| 摘 要： | 以旱区广大群众最为关心的种植密度,滴水量,施肥量为考虑因子,将棉花单铃重,衣分,籽棉产量作为考查指标,把正交试验设计方案引入高密度棉花膜下滴管研究中.采用归一化处理不同数量级的指标,比以往单独考虑各因素对指标的作用,合理而又更加直观;同时考虑了误差对指标的影响,从而提高了F检验的灵敏度.得出了在膜下滴灌的新疆旱区,土壤...

| Abstract: | The article is based on taking planting density,irrigation quantity and fertilization factors to consider,which are most concerned in the arid region,and considering boll weight of cotton,lint and seed cotton yield as indexs,the drip irrigation of cotton with high planting density by means of orthogonal experiment.we analyze error on indicators in order to raise the sensitivity of F-Test and deal with indicators by unitary processing that is more reasonable and intuitive than considering the effect of various factors on the indicators separately.Result shows that seed cotton yield is the highest with boll weight,lint and other quality increased when soil fertility in Xinjiang is moderate,planting density is between 225,000and 250,000 plants / hm2,irrigation quantity is about 300mm,and standard fertilizer is 2,200kg/hm2.This conclusion provides the theoretical basis for local production. |
