不同土壤改良剂对盐碱地棉花产量的影响
Effects of Different Soil Ameliorant on Cotton Yield in Saline-alkali Land
摘要
Abstract
Objective] The aim was to select the optimal combinatiion of saline-alkali cotton.[Method] Using the orthogonal experiment de-sign with four factors and three levels, effects of compound fertilizer, humic acid, phosphogypsum and cow dung on plant height, fruit-bearing branch number, number of bolls and yield of cotton were studied.[Result] The results showed that phosphogypsum was the most influential for cotton yield. The best ameliorant combinantion was compound fertilizer 450 kg/hm2 , humic acid 600 kg/hm2 , phosphogypsum 22 500 kg/hm2 , cow dung 7 500 kg/hm2 .Under this treatment, cotton plant height was medium level, fruit-bearing branch number and num-ber of bolls were the highest level, the seed cotton yield was 3 146.8 kg/hm2.[Conclusion] The study can provide technical support for im-proving cotton yield in saline-alkali land.关键词
