棉花进入开花结铃期,正是上海伏旱季节。这时棉花需要大量水分,以保证棉株体内各项生理活动的正常进行。适时抗旱,就能使棉花多结铃,结大铃,产量高,品质好。然而,由于对“三看”(看天、看地、看棉花长相)技术的认识不一致,采取的灌溉措施不同,抗旱的效果也就不一样。现就学习泥城公社人民大队关于棉花花铃期灌溉的实践经验,谈谈我们的体会。 Cotton into the flowering period, it is the summer drought season in Shanghai. At this time, cotton needs a lot of water to ensure the normal physiological activities of cotton plants. Timely drought, we can make more cotton boll bell knot bell, high yield, good quality. However, due to the inconsistent understanding of the technologies of “Three Looks” (looking at the sky, looking at the place and looking at the cotton), the irrigation measures adopted are different and the effects of drought control are different. Now study the people’s brigade of mud city commune on cotton flower irrigation period of practical experience, talk about our experience.
