目前,在大面积棉花生产上,一播全苗壮苗技术还很不过关,大部分棉田每年总有不同程度的缺苗。我团场历年因大量缺苗断垄而不得不补种移栽的棉田比例常常不下三分之一至二分之一,如遇气候反常年份,棉田缺苗断垄情况达到二分之一以上。由于不能一播全苗,带来很多不良后果,造成一系列田间管理极为被动。诸如三类苗比例激增,棉苗发育推迟,密度得不到保证,面积完不成计划。全团场棉花每年由此浪费了大量的人力和物力,也影响了棉花的产量。调查分析各连队棉田缺苗断垄的原因,总结推广一播全苗壮苗的技术经验,对高速度发展棉花生产具有很现实的意义。为此,根据我团场多年棉花生产的实践及保棉花全苗壮苗的有关资料做了认真的分析归纳,现综述如下:
At present, in a large area of cotton production, a broad seedling strong seedling technology is still not pass, most of the cotton fields each year there are varying degrees of lack of seedlings. In recent years, due to a large number of lack of seedlings and breaking the ridge in our country, the proportion of cotton fields that have to be planted with transplanting is often not less than one-third to one-half. In case of weather anomalies, . Due to the inability to broadcast the whole plant, it brought many adverse consequences, resulting in a series of field management activities that were extremely passive. Such as the proportion of three kinds of seedlings surge, delayed cotton seedling development, density can not be guaranteed, the area can not be completed. The whole group of cotton each year wasted a lot of manpower and material resources, but also affected the production of cotton. Investigating and analyzing the reasons for lack of seedling and breaking ridge in the cotton fields of various companies and summarizing and popularizing the technical experience of planting all seedling and strong seedlings has very realistic significance for developing cotton at a high speed. To this end, according to my field of cotton production for many years and ensure that all cotton seedling strong information on the relevant information has been carefully analyzed and summarized are summarized as follows:
