我国多数棉区,在棉花蕾、花期常遇高温、多雨的天气,尢其在水肥充足的情况下,极易造成棉株徒长,使生长与发育失调,影响了棉花的稳产、高产和纤维品质。解决这个问题需要靠综合的农业技术措施,其中包括研制和使用新的植物生长调节剂,以便通过调节棉株内部激素代谢等生理生化过程,更有效地协调棉株的营养生长和生殖生长的关系,塑造比较理想的株型和田间结构,改善成铃结构增加铃重,使棉花获得高产、稳产和提高纤维品质。
In most cotton fields in our country, cotton buds and flowering often encounter high temperature and rainy weather, especially in the case of sufficient water and fertilizer, which can easily result in the growth of the cotton plant and the imbalance of growth and development, which affects the stable yield, high yield and fiber quality of cotton. The solution to this problem requires a combination of agro-technical measures, including the development and use of new plant growth regulators to better coordinate the vegetative and reproductive growth of cotton plants by regulating physiological and biochemical processes such as hormone metabolism within the plant , Shape the ideal plant type and field structure, improve boll structure and increase boll weight, make cotton get high yield, stable yield and improve fiber quality.
