| 摘 要： | 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30~45 kg/hm2,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3.8~10.2 cm,铃数增加5.7万~9.4万个/hm2,铃重增加0.1~0.19 g;并且以穴施最经济有效。

| 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/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. |
