棉花营养钵育苗,是夺取高产的重要措施。但据笔者近几年的调查,植棉区总是免不了因管理不当而造成烧芽烂种死苗现象,其死苗率在17.5%～28%左右,尤其是在4月中下旬至移栽前,苗床管理稍有闪失,即导致高温烧苗,有的前功尽弃,因此播种以后,抓好苗床管理,是提高成苗率的关键。出苗前,要高温、高湿催全苗,水分是主要矛盾。薄膜育苗的苗床温度高,耗水大,而棉籽要吸 Cotton nutrition bowl nursery, is an important measure to seize high yield. However, according to the author’s investigation in recent years, cotton growing areas are inevitably caused by improper management of burned buds dead seedlings phenomenon, the dead seedling rate of 17.5% ~ 28%, especially in late April to transplanting Before the seedbed management a little accidental loss, which led to high temperature burning seedlings, and some tried out, so sowing, do a good job of seedbed management, is to improve the rate of seedling rate. Before emergence, to high temperature, high humidity reminder seedlings, water is the main contradiction. Film nursery seedbed temperature is high, water consumption, and cottonseed to suck
