孙智慧同志: 《新疆农垦科技》编辑部转来你的来信。你在信中提到秋收拾花时发现棉花“僵瓣子”特别多,有的人说是采用地膜后引起的;也有人说是化学除草剂的副作用。我认为这些说法是没有根据的,也不确切。生产实际证明,地膜植棉和化学除草都不会增加僵瓣花的比例,僵瓣花的形成主要是病虫害的结果。 棉花的生长发育,需要一定的外界环境条件,人类在长期的栽培过程中,根据棉花的生育规律,千方百计采取措施创造较适宜的环境条件,促使棉花有一个良好的生长发育进程,以争取达到高产、稳产、优质、早熟的目的。
Comrade Sun Zhihui: “Xinjiang Agricultural Reclamation Science and Technology” editorial department transferred your letter. You mentioned in the letter that when harvesting flowers in autumn, you find that there are so many “petals” of cotton that some people say it is caused by the use of plastic film. Some people say that it is a side effect of chemical herbicides. I think these statements are unfounded or incorrect. Production proved that plastic film mulching and chemical weeding will not increase the proportion of stiff petal flower, stiff petal flower formation is mainly the result of pests and diseases. Cotton growth and development, the need for some external environmental conditions, human long-term cultivation process, according to the law of the birth of cotton, do everything possible to take appropriate measures to create a more suitable environmental conditions, to promote cotton have a good growth process in order to achieve high yield , Stable production, high quality, precocious purpose.
