在地、县科委的重视和支持下,《应用酶制剂防治蕾铃脱落试验》的课题,经过五年三个点试验,已经告一段落,现将该项试验总结如下: 棉花的蕾铃脱落是生产中的一个普遍现象,脱落率一般在60～70％,严重的高达80％,影响棉花产量。因此,认识蕾铃脱落的原因和研究减少蕾铃脱落的途径,对提高棉花单位面积产量有着重要的意义。棉花蕾铃脱落的机理,国内外有许多学者,做过研究,曾提出一些假设和学说。例如英国植物
At the prefectural and county science and technology Commission’s attention and support, the subject of “Application of enzyme preparation for prevention and control of the falling-off of the lampblack” has come to an end after three years of three-point tests. Now, the test is summarized as follows: Is a common phenomenon in production. The rate of shedding is generally 60-70% and the severity is as high as 80%, affecting cotton production. Therefore, it is important to know the reasons for the shedding of the buds and the ways to reduce the shedding of the buds. It is of great significance to improve the yield per unit area of cotton. Cotton buds off mechanism, many scholars at home and abroad, did research, had put forward some assumptions and doctrines. For example, British plants
