鲁西地区棉花苗期病害的发生特点与防治方法

The Oil Content Difference of Cottonseed Harvested at Different Locations and Different Periods

棉花苗期病害及其如何防治一直以来都是鲁西地区困扰棉农的难题。通过对鲁西地区棉花苗期病害发生特点的分析,从种子处理、农业防治、化学防治三个方面提出了温汤浸种、药液浸种、药剂拌种、种衣剂应用、精选良种适期播种、深耕冬灌精细整地、及时中耕提高地温和喷药防病等防治技术,为广大棉农提供参考。

This paper takes conventional cotton E- kang 9 as test material,study the effect on the cottonseed oil content determination under harvested at different locations and different periods. The results show that: with time after the shift,cottonseed oil significantly increased; in the longitudinal space,cottonseed oil content has no significant difference in 1 ~ 9 cotton boll branches,in the upper part boll cottonseed oil content was significantly higher than that of the lower boll; in the horizontal space,the inner boll,middle boll and peripheral boll,cottonseed oil content have no significant difference; the same seed with prolonging the storage time,the oil content has the increasing tendency year by year.
