不同种植方式对棉花出苗率、产量及纤维品质的影响

Effect of Different Planting Methods on Cotton Yield and Fiber Quality

以鲁棉696作为供试材料,设置播种时间(5月25日、6月5日)、播种深度(3cm、5cm)和覆盖物(基质、50%基质+50%耕作层土壤、耕作层土壤)的三因素再裂区试验。探究不同处理方式对棉花出苗率、产量、纤维品质的影响。试验表明,选择6月5日播种,播种深度为3cm,覆盖物为50%基质+50%耕作层土壤,棉花出苗率、产量、纤维品质达到最优。

Using 696 as the test material,set sowing time(May 25,June 5),sowing depth(3cm,5cm)and covering(substrate,50%matrix+50%tillage soil,tillage soil).Explore the influence of different treatment methods on cotton seedling yield,yield and fiber quality.The experiment showed that sowing on June 5,with a sowing depth of 3cm,the covering of 50% substrate+50% tillage soil,reached the optimal cotton yield,yield and fiber quality.
