一.試驗的目的本試驗的目的是探索各种棉籽处理方法对于防治棉苗病害的效用。一方面,通过对比的方法,进一步明确在南方棉区的具体条件下,目前所推行的温湯浸种和藥剂拌种的效果大小;另一方面,探索抗生素对于防治棉花苗期病害的作用。对于已推行的温湯浸种和藥剂拌种的防病效果,近年来各地区棉农反映不一致,有的已加以肯定,有的認为效果不显著,有的甚至于認为反而造成不良后果——燙种影响出苗率。引起这样分歧結果的原因究竟是在哪里?一方面可能是由于处理的技术掌握得不一定恰当,但是另一方面不同的土壤、气候以及棉籽等条件对于同一种处理方法的反应也可能有差异。因此,在一种条件下已經肯定的办法,在另一种条件下必須經过进一步的試驗証明。
The purpose of the test The purpose of this experiment is to explore the effectiveness of various cottonseed treatments for the control of cotton seedling disease. On the one hand, the contrast method is used to further clarify the effects of soaking seeds and medicinal seed dressing in the southern cotton area under the specific conditions; on the other hand, to explore the role of antibiotics in the prevention and treatment of cotton seedling disease. In the recent years, cotton farmers in all regions have reflected inconsistencies, some have affirmed it, and some have found that the results are insignificant, and some even think that it has adverse consequences instead - Hot species affect the emergence rate. Where are the causes of such disagreements? On the one hand they may be due to improper handling of technologies, but on the other hand different conditions such as soil, climate and cottonseed may also respond differently to the same treatment. Therefore, the method that has been affirmed under one condition must be proved through further tests under another condition.
