保水剂对土壤和棉花生长发育及产量的影响

Effect of Aquuasorb on Soil and Growing Development and Yield of Cotton

通过盆栽和田间试验，主要研究保水剂对土壤和棉花生长发育的影响。结果表明：土壤中的保水剂含量在0．030％～0．100％内，土壤表面蒸发明显降低，pH值趋于酸化；保水剂的用量在30～45kg／hm^2，能够明显提高棉花的产量，增产幅度达10％以上，对纤维品质没有影响，株高增加3．8．10．2cm，铃数增加5．7万～9．4万个／hm^2，铃重增加0．1～0．19g；并且以穴施最经济有效。

The bonsai and the field experiments have been carried out to discover the effect of aquasorb on soil and breading to the growth of cotton. According to the experiment results ： When content of the polymer in soil was in the range of 0.030% -0.100% ,evaporation of soil moisture was deceased,the pH value tended to be lowered; amount used in 30- 45 kg/ha could obviously increase the output of the cotton, the production increase scope reaches above 10 % ,to the textile fiber quality not tremendous influence, high increases 3.8 - 10.2 cm, the bell number increases 5.7 ten thousand- 9.4 ten thousand per ha, the bell increases 0.1 -0.19 g;and it was the most economical to fertiliz in pre-dug holes.
