摘要
在荒漠绿洲带的南疆进行免耕种植不同播期的棉花。结果表明:同一播期内,免耕条件下的棉花株高矮于传统耕作的,但有效果枝数与单株成铃数都高于传统耕作,其产量间的差异不显著;不同播期棉花之间的产量差异达到5%显著水平。在免耕下,播期为4月15日的棉花产量最高。
The cotton is planted in different times in no - tillage land in south Xinjiang that belongs to desert oasis belt. The result shows that, within the same sowing time, the height of cotton which is planted in no - tillage land is lower than that planted by tradition cultivation, but the numbers of availability cotton branch and bell of individual plant is beyond the traditional cultivation cotton. The output has no difference. However, the output difference between the cotton which is sowed in different periods reaches 5 %. The production of cotton whose sowing time is April the 15th is the highest under no - tillage.
