为了了解棉花的主要器官(叶、蕾、花、铃)之生育进程,以便为其优质高产栽培技术提供理论依据,我们于1984—1986年对地膜棉花单株生育进程进行了观察.供观察的品种为新陆早1号,其中1984年在一四二团观察4株(4月25日播种);1985年在一二二团良种站观察6株(4月17日播种),在本所试验地观察10株(4月21日播种);1986年在本所试验地分别于4月12,17,22,27日和5月4日播种,每一播期观察2株.各试验点均采用60+30厘米宽窄行方式播种.从棉苗第一片真叶出现之日起,
In order to understand the fertility process of main organs (leaves, buds, flowers and bolls) of cotton in order to provide a theoretical basis for its high-yielding and high-yielding cultivation techniques, we observed the cotton plant growth process from 1984 to 1986 The variety was Xinluzao No.1, of which 4 were observed in one hundred forty-two regiments in 1984 (sown on April 25); six were observed at one hundred and twenty-two regiment (1985) in 1985 (sown on April 17) Ten plants were observed experimentally (sown on April 21); in 1986, the two plants were sown in April, 17, 22, 27 and May 4, respectively, and two plants were observed in each sowing date Are using 60 +30 cm wide and narrow row way sowing.From the first true leaf appear on the date of cotton seedlings,
