【摘要】 通过盆栽和田间试验研究了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％范围内,土壤表面蒸发明显降低,pH值趋于酸化;用量在每公顷30-45 kg内能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3．4-11．3 cm, 公顷总铃数增加5．7万-9．4万个,铃重增加0．1-0．19 g;并且以穴施使用最经济有效。更多还原

【Abstract】 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 · hm-2 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 3.4 - 11. 3 cm, the bell number increases 5. 7 -9. 4 ten thousand per hectare, the bell increases 0. 1 -0. 19 g;and it was the most economical to fertiliz in pre-dug holes.更多还原
