Recently, when the author investigated the province's main cotton producing areas in Hubei, Hunan, Jiangxi, and Hebei provinces, several new conditions emerged in cotton production this year. First, the comparative benefits of cotton planting have decreased, and many farmers have been facing cotton fields. The selection of area is very late, many have not applied base fertilizer, and the fertility of the cotton field is insufficient; second, increasing the number of wheat and rapeseed pods, the harvest is delayed accordingly, and early application of base fertilizer cannot be applied ahead of time; third, the availability of available nitrogen fertilizer on the agricultural resources market is insufficient to meet cotton Fertilizer demand. Therefore, in the management of cotton seedlings, we must highlight the use of topdressing as a remedy, pay attention to top-dressing at the seedling stage, apply early seedlings, and promote early growth of cotton seedlings. Why should we put special emphasis on the application of cotton seedlings? The reasons are as follows: One is that the cotton seedling stage is the period with the highest nitrogen content in all growth stages. The nitrogen metabolism is the most active during the seedling stage. The nitrogen content in this stage is more than 3.3%, which is higher than other fertility stages. The second is the growth rate of the main root of cotton seedlings, which is 4-5 times faster than the young shoots on the ground. After the first true leaf of cotton is developed, the nutrients stored in the cotyledons are basically used up. If the fertilizer supply is insufficient, the extension of the main root and the development of lateral roots will be inhibited. In production, it is necessary to “strengthen the seedlings first to build a strong root and to develop a deep rooted seedling.†Third, the temperature of cotton at the seedling stage is relatively low, with less light, more rain, more soil moisture, poor permeability, microbial activity is blocked, the organic matter decomposition and nutrient release rate in the cotton field is slowed down, if the top dressing is late and less, the cotton root is not easy to be absorb. Fourth, there is not enough stamina in cotton field soil, the soil organic matter content shows a downward trend, and the storage fertilizer and fertilizer supply capacity are weakened. Fifth, some cotton fields are extensively cultivated, and the amount of base fertilizer applied is not large, and it is applied to the surface of the soil. After the rain, the loss of nutrients is more. Sixth, the application of a good seedling fertilizer, one can increase the seedling factor of cotton; two can increase the number of real leaves; three can increase the true leaf area and increase the photosynthetic efficiency; four can accelerate the growth process. According to the research of the agricultural scientific research department, after three true leaves appear in the cotton, the flower buds begin to differentiate. Applying the seedlings can promote early-onset early-onset growth, allowing flower buds to differentiate earlier, and then lead to early budding, early flowering, premature peach growth and early harvest. The following improvements should be made in the top-dressing techniques of cotton: First, the seedlings must be planted on a seedbed before transplanting. Sending marrying manureâ€, after the transplanting, early recovery of An Miao Fei; second is to change the application of delayed fertilizer as a quick-effect fertilizer, promote the application of ammonium bicarbonate and urea, Dingmiao should be followed by fertilizer twice, 3-4 true leaves when chasing the first Times, 8-9 kg of ammonium per acre or 3-3.5 kg of urea. When 6-7 true leaves are chased once, 15 kg of ammonium bicarbonate or 5 kg of urea per mu. The use of fertilizer at the foot of the cotton field, can be reduced as appropriate; the third is to change the applicator, shallow device for the ditch or play deeper, to reduce the loss of fertilizer; Fourth, change the dry water after application, fertilizer to the water, According to the Institute of Measure, Yunmeng County, Hubei Province, the content of available nitrogen in cotton soil at the seedling stage was 17.5 PPM (millions), and that after watering was 25 PPM (million). 7.5PPM (million parts), the effect is significant.
