Selection of high-quality, disease-resistant varieties: Terry Peak, Shuangkang, Yapeng 58, Zhongshe No. 4, Jiafen No. 10 and other late-maturing varieties, in recent years mainly used wool 802 for post-production delay. ? Grasp the appropriate sowing date: generally determine the sowing time according to the arrival time of the early frost. Generally 100 to 110 days before the box for the sowing period. North China is mostly planted in the middle of July. ? Live with a shed to ensure that Miao Miao Zhuang, and prevent poisoning. Judging from the experience of the past years, all the transplanting in the autumn is heavy and the live virus is light. Compared with transplanting, direct seeding has the advantages of not damaging the roots, preserving seedlings, reducing the chance of virus infestation, eliminating the time for seedlings to grow, and strong growth potential. ? Greenhouses are covered with high-temperature and anti-aging film, and they are covered with greenhouses in the early stage. They can be covered with live air from the seedling stage, and can prevent rain, high ground temperature and rain erosion from the seedling stage, which will help the seedlings thrive. In order to prevent the disease and ensure the seedlings are full, we have the following measures: (1) Clean up the environment, fertilize the soil, increase the application of phosphorus and potash fertilizers, and avoid the removal of litter and debris from the front hoeing vegetables and the weeds surrounding the greenhouse where the locusts are likely to breed, and then perform fine soil preparation and fertilization before replanting. According to the fertility of the soil and the amount of fertilizer applied to the Shangyu vegetables, 2,000 to 5,000 kg of decomposed organic fertilizer per 667 m2 is appropriate. In addition, the application of phosphorus and potassium compound fertilizer 20 to 30 kg or 200 to 300 kg of cake fertilizer, is conducive to enhance resistance. ? (2) Seed disinfection, the amount of inactivated virus per 667 square meters of 100 to 150 grams, seeds first soaked with water for 4 to 6 hours, and then disinfected with 10% trisodium phosphate or 1% potassium permanganate solution for 20 minutes, After that, use water to wash the liquid for germination. Can also not germination, soaking after sowing. ? (3) Grasp the sowing technique and the rule of seedlings and seedlings to ensure that the whole seedlings are grown and the width of the seedlings is 0.8-1.0 meters. Open two rows of planting trenches each, 6.7 centimeters deep and wide. Ditch the bottom water. After the water infiltrates, 2 to 3 seeds are sown every 30 to 34 cm. Seeds should be dispersed properly. Cover soil 1 cm thick after sowing. For sunshading and lowering the temperature and preventing sun exposure, small oil radish or fennel (4 kg per 667 m2 (1 mu)) can be sowed in advance between the rows in the bank. The seedlings grasp the principle of early seedlings, multiple seedlings, late seedlings, and preservation seedlings. Out of crowded seedlings after the Qimiao. 2 to 4 true leaves during the crowded, sick and weak seedlings, leave two plants per hole. The seedlings will be set before and after mid-August. Dingmiao should choose strong, remove diseased seedlings and weak seedlings. Each 667 square meters (1 acre) Bao Miao 4000 ~ 4500. Can not be too dense, to prevent the late Miao long. ? (4) Water Management at Seedling Stage Wet and moist surfaces should be maintained throughout the seedling period. Seedling water 2 to 3 times, in the morning and evening, will help reduce and stabilize the temperature. After emergence and sub-seedling, sub-cultivation was carried out to protect the roots, and the ground temperature was stabilized. Gradually, small ditches were cultivated to form small ridges. ? (5) Apply growth inhibitors to prevent leggy seedlings from being susceptible to extreme longevity under conditions such as shading, weak light, high temperatures, and high soil moisture. For this purpose, when the two leaves are at one heart, 500 micrograms/gram of chlormequat is sprayed once every 7 days, and the growth can be suppressed for three consecutive times. ? (6) Regular use of pesticides at seedling stage, prevention of phytotoxicity, damping-off, and blight are the first steps in the eradication of lice and eradication of transmission vectors. Before the seedlings were exhumed, a high concentration of stubble was sprayed on the ground, on the scaffolds and around the perimeter. Every 7 to 10 days thereafter. Medications should be used alternately to prevent aphids from developing resistance, and they should be treated early to cure them. Spraying should be thorough and detailed, and leaves and leaves should be sprayed. Hanging silver ash film (10 cm wide) at the mouth of the shed will have 2 to 3 strips, which will have a certain effect. Secondly, anti-poisoning agents are regularly sprayed at the seedling stage. Use 1000 times solution of plant disease spirit, or 1000 times solution of phytoalexin, and 83 to 100 times 50 times of agent. 0.1% potassium permanganate plus 0.2% potassium dihydrogen phosphate mixture, etc., alternating, once every 15 days, a total of 3 to 4 times. Thirdly, plant growth promoters can be sprayed 2 or 3 times at the seedling stage, such as multi-increase and high-yield production. In particular, sunny days after the cloudy days, the sugar nitrogen solution (0.3% concentration of sugar and urea) can be sprayed. Nutrition, promotes robustness, and enhances resistance to disease. Fourth, we must avoid human trafficking. Pull out poisonous strains separately and then wash hands with soap. ? Doing a good job in mid-term management: At this time, from late August to the end of September, it is a good opportunity for tomato growth after the fall. The focus of management is to ensure that the fruit is protected. ? (1) The management of water and fertilizer is generally done by pouring a large amount of water in 7 to 8 leaves of the seedlings and then cultivating the seedlings. The ideal plant type of seedlings is: the plant half-stretched and half-shrinked, but it does not turn over. The tip of the plant does not spit water or have slight drops of water in the morning. Afterwards, the leaves do not sag or slightly droop to a moderate degree. If the leaves of plants are hypertrophic and stretched, they are of a long-length type, and they must strengthen the cultivator, and they may spray Ketocin to control their growth. During the seedling stage, if the weather is too dry or the soil is too arid, it can also be poured in small amount in the flowering period, and shallow cultivating. When the first fruit is sitting, it begins to pour water and promote fruit enlargement. Every 7 to 10 days after the water, to ensure that the soil is moist. After the water to enhance ventilation and dehumidification. When the fruit on each plant has been seated, watering should be reduced to promote fruit ripening. ? Top dressing is generally every time sitting and catching fruit and watering to chase a fat. Each 667 square meters (1 acre) sub-urea 15 to 20 kilograms, or ammonium sulfate 30 to 40 kilograms, 15 to 20 kilograms of ammonium phosphate, 30 kilograms of ammonium nitrate. ? (2) Decorating fruits and plants to adjust flowering and fruit setting in late August, the temperature is high, and the temperature difference between day and night is small, and it is easy to fall flowers. Generally, 10 to 20 micrograms/gram of 2,4-D silk flower or 30 to 40 micrograms/gram of tomato flower spray is used to increase fruit setting rate. The use concentration increases with the seasonal temperature. To prevent empty fruit, add 10 μg/g gibberellin to decorate. ? Immediately before flowering, the vines were put into a rack and single branches were pruned. The growth period is short in the fall, leaving three panicles topping. In order to increase the rate of large fruit, each fruit is selected and left to retain 3 to 4 large fruit, and the excess fruit and fruit are removed in time. The bottom old leaves and diseased leaves were removed late. ? Strengthen late management: In October, the outside weather gradually turned from warm to cold. The management focuses on heat preservation, cold prevention, and moisture prevention and disease prevention. ? (1) Temperature and humidity management with live tomato in greenhouses. In July and August, the weather is hot and the ventilation should be increased as much as possible; in the rain-free weather, the top wind must be put; straw or straw curtains should also be used to cover the flowers on the roof. Shade, so that the greenhouse temperature is not higher than 30 °C during the day, not higher than 20 °C at night. After September, the outside temperature dropped, gradually falling film to reduce the ventilation volume, and appropriately increasing the temperature and stimulating the fruit. In the middle and late September, when the outside minimum temperature reaches 15 to 12°C at night, the surrounding area will be tightly sealed. Increase ventilation at noon in the morning to eliminate moisture and prevent disease. In October and mid-October, the night temperature in the shed fell to 10°C, and the top seam insulation was closed so that the shed temperature was maintained at 20 to 25°C during the day and not less than 5°C at night. If the night temperature was below 5°C, it was prone to frost damage. Should be promptly harvested. Infertility nights should be installed in the greenhouse when the night temperature dropped to 10 ~ 12 °C. ? (2) Water and Fertilizer Management The amount of watering in early October should be small. After the water is used, ventilation and dehumidification should be strengthened to reduce the amount of condensation and condensation time. To prevent premature aging, a small amount of urea can be traced. The water is stopped in mid-October. ? (3) Strengthen the prevention and treatment of disease After the film is placed, the humidity in the greenhouse is high, and it is prone to diseases such as early plague, late plague, and leaf mold. In addition to enhancing ventilation and dehumidification, it should also be combined with chemical control. Such as chlorothalonil, Ruizhi mildew, metalaxyl manganese zinc, phosphorus aluminum, mancozeb, antiviral, thiophanate-methyl, etc., alternating use, 7 to 10 days 1 time. ? Timely harvest freeze protection and do a good job of storage and listing in phases. Late autumn tomatoes are generally harvested before and after mid-October. For early harvest and marketing, it is also possible to use 1000-2000 μg/g ethephon ripening. From late October to early November, when the temperature of the shed falls below 5°C, especially when the temperature of the cold stream is forecasted, all antifreeze should be picked in time. The picked fruit can be stored at a low temperature of 0.5 to 2°C. Picked green ripe fruit can be stored in greenhouses in stages. Its storage method is: (1) The fruit is sprayed with 50% carbendazim 500 times for 5 days before picking to reduce the rot in the storage period. ? (2) Greenhouse disinfection before entering the room can be sterilized with sulphur, and chlorothalonil can also be used for all-in-one spray disinfection. Generally, about 3,000 kg of tomatoes can be stored in the greenhouse at 1 point. ? (3) Fruit sorting Select green ripe fruit without wounds, lesions, or insect eyes for storage. The fruit and unripe fruits were soaked in 200 μg/g ethephon for 3 minutes, and matured at 20 to 25°C. ? (4) Storage method Generally, the straw is laid on the ground, and then 3 to 4 layers of fruit are stacked in parallel, and the straw is covered (though it cannot cover the film). During storage, the temperature is 10 to 12°C, not less than 8°C, no more than 15°C, and humidity 70% to 80%. Turn over once every other week to remove fruit and rot. This can be listed for supply to New Year's Day or even the Spring Festival.
