Effects of Soil Amendment Fertilizer on Cotton Growth and Yield

Abstract:

As new approaches to comprehensively utilize urban-rural wastes, waste resources and straws of wheat, maize, cotton, rice, rape and etc. (as principal raw material) were used to prepare environment-friendly products(soil amendment fertilizer) for water-saving agriculture (the processing techniques were established).In this paper, the cotton growth and yield were studied under the application of water-saving products(soil amendment fertilizer). Results show: for all prescriptions, under the application amount of 750kg/hm2 (equivalent to regular fertilization and investment), the fresh and dry weight in cotton seedling stage increased by 10-20% over control and the prehot seasonal boll increased by 2.0-2.54/plant compared with control respectively; the yield under all prescriptions increased over control with an increasing range of 4.70-14.25%; the quarterly irrigation can be decreased by 1-2 times(saving irrigation amount of 600-1200m3 /hm2).The above results show that soil amendment fertilizer can not only conserve moisture, but also increase soil fertility, promote cotton seedling growth and increase dry matter accumulation.
