棉花育苗移栽已在生产上普遍应用和推广,收到了显著地增产效果。为了更好地掌握育苗移栽技术,进一步探讨不同移栽期、苗令、温度与缓苗的关系,从而找出育苗移栽的适宜时期和苗令,我们研究了棉花育苗移栽中的几个问题。研究方法试验地为两合土。PH7.5左右,地下水位约1.5米,有机质0.76％。试验均采用营养钵塑料薄膜保温育苗。品种为徐州142。1975年试验面积为一亩。3月20日播种育苗,4月31
Cotton seedling transplanting has been widely used in production and promotion, received a significant increase in yield. In order to better grasp the seedling transplanting technology to further explore the different transplanting period, Miao Ling, the relationship between temperature and Huanmiao to find the appropriate period of seedling transplanting and Miao Ling, we studied the transplanting of cotton seedlings in the few A question. Research methods test for the two combined soil. PH7.5 or so, groundwater level of about 1.5 meters, 0.76% of organic matter. Experiments are nutrition bowl plastic film incubation nursery. Variety for Xuzhou 142. 1975 test area of one acre. March 20 sow seedlings, April 31
