Applying “control lost fertilizer†can save at least 10 kilograms of fertilizer per hectare of cotton fields, save 1.5 workers and increase the output of 17 kilograms of seed cotton, which is equivalent to a direct increase of income of 86 yuan. This figure is a one-year subsidy for the farmers to plant one mu of land per year. sum. The reporter learned from the Seminar on Controlling Lost Fertilizer Experiments in the Yangtze River Cotton Region held in the province recently that the loss-controlling fertilizer developed by the Key Laboratory of Ion Beam Bioengineering of the Chinese Academy of Sciences has been successful in demonstrations along the Yangtze River.
In the past, due to the backward use of traditional fertilizers, the farmland utilization rate of chemical fertilizers was only about 35%. The vast majority of nitrogen fertilizers evaporate into the air and into rivers, lakes and seas, threatening human and livestock health. "Controlling Lost Fertilizer" not only has a good control effect of nitrogen fertilizer, but also has the characteristics of environmental protection, natural degradation, long-term application can improve soil physical and chemical properties, improve soil fertility and water retention capacity.
The scientific and technical personnel of the Institute of Cotton Research of the Provincial Academy of Agricultural Sciences studied the growth and development of cotton, the distribution of three peaches, and the composition of yield in the loss-controlled nitrogen fertilizer experiment. The results showed that: Cotton with loss-control nitrogen fertilizer was growing steadily in the early stage, and compared with the control in the middle and late period. Significantly increased, Qiu Tao increased by 36.31%, production increased by 10% to 25%, in the case of reducing the use of fertilizer 10% to 30% of the case, the cotton yield does not decrease. Experts from the Provincial Agriculture Commission pointed out that controlling one or two lost fertilizers will solve the problem of fertilizer requirement for the whole cotton growing period, and it will increase the yield, and solve the problems of large amount of fertilizer used for cotton, many times of fertilization, and difficulty in fertilizing.
