In the management of comprehensive agricultural technical measures in tea gardens, the effect of rational fertilization on tea production and quality improvement is most significant. Reasonable fertilization in tea plantations should depend on the age, vigor, and yield of tea plants; the nutrient levels, physical and chemical properties of tea plantations; and the types and nature of fertilizers in tea gardens as well as seasonal weather conditions. Most of the middle and lower reaches of the Yangtze River in China are in the early summer of Meiyu period, accompanied by heavy rain, high-temperature and hot summer droughts and droughts, so the summer tea garden fertilization technology is particularly important. The microbial fertilizer expert, Golden Baby, will make the following recommendations in this article on some considerations for tea summer pruning:
1. The characteristics of the timeliness of summer tea fertilization seize the season, and it is a magic weapon in agriculture when it is not in violation of agriculture. In the tea plantation, summer fertilization also has to take care of the season. Since the interval between spring tea and summer tea is short, it is better to use early dressing in the tea garden in the summer. The vigorous growth and multiple picking of the tea tree by the spring tea consumes a lot of nutrients in the body, and the nutrient reserves in the tea tree body and the tea garden soil will have different degrees of deficit. In addition, the summer is the peak season for the reproductive growth of tea trees. When the flower buds were bred in large quantities, the fruits grew rapidly in the previous year and consumed a lot of nutrients. If they are not top-dressed in time, the tea tree nutrients will be disjointed, affecting the growth and growth of the summer shoots, showing budding shoots. Less, slow growth, short internodes, yellow leaves, small leaves, thin leaves, multiple buds (for clips) and other symptoms, affecting both yield and quality, so it is necessary to timely fertilizer. The first summer top dressing is applied immediately after the end of the spring tea, usually in mid-to-late May. The southern tea region can be advanced to late April or early May. The northern tea region can be extended to early June. The second top dressing in summer can be performed after the end of the second tea, in about the end of June and early July. It is customary to call this secondary top dressing a “relay fat” or “fat fat fertilizer.” Green food tea gardens and organic tea gardens should be selected by specialized agencies and meet the types of fertilizers allowed in green food tea gardens and organic tea gardens, such as manure (not Include banned substances proposed by licensing agencies, human and poultry excrement (harmless treatment), organic tea special fertilizer, etc. If tea farmers in organic tea gardens want to better improve the quality of tea, we recommend The baby's microbial fertilizer is applied to the base fertilizer together. This not only ensures that the whole plant nutrients are easily absorbed, but also beneficial substances secreted by microorganisms in the bacterial fertilizer will increase the disease resistance and growth speed of the plant.
2. The amount of fertilizer to be used in tea plants in summer should be emphasized. The amount of top dressing in summer tea gardens depends on the age of the tree, the growth potential is strong and weak, the level of tea production is high, the soil nutrient level in tea gardens, and the management level of tea plantations are taken into consideration. The tea yield is the main factor used to determine the amount of fertilizer. in accordance with. In general, 100 kg of dry tea is produced per acre, and the annual total nitrogen application is about 15 kg, of which the top dressing accounts for about 50% of the annual nitrogen application. The amount of topdressing fertilizer in the summer accounted for about 25 to 30% of the annual nitrogen application rate, that is, the first time in the summer (in late May), accounting for 10% of the annual nitrogen application rate; and the second time in the summer (2 after the tea). From late July to early July, it accounts for 15 to 20% of the annual nitrogen application. Three teas are often classified as autumn tea in production, so the second summer fat is also called autumn fat. General production of tea gardens, such as the use of special compound fertilizer for tea, can be used after the spring tea and after the second tea, Mu 50 to 100 kg. In the tea gardens with water sources, the foliar fertilizer can be sprayed once before the second tea and before the three teas in the summer. The foliar fertilizer concentration is: ammonium sulfate 1%, urea 0.5 to 1.0%, Aonong 300 times solution, and Fuquan 300 times Liquid, EM 1000 times liquid, brassin 10000 times, etc., as a supplement to the top dressing. About 150kg per acre spray fertilizer solution.
