Cotton is the main economic crop in Taocheng District of Hengshui City. It is the main source of income of peasants. To increase the yield of cotton and improve the quality of cotton, the implementation of soil testing and formula fertilization technology is an important measure. This year I stood in Peach City Pendu Township agricultural technology demonstration base to promote a 300-mu cotton formula fertilizer demonstration. First of all, we collected soil samples prior to sowing cotton for laboratory analysis, the test results 0-20 cm soil organic matter content of 1.105% -1.423%, an average of 1.214%; alkaline nitrogen content of 70.5ppm-81.3mm, an average of 74.2ppm ;
