我县常年棉花铺地面积十万亩左右,是江苏省中等产棉县,过去棉花产量,一直低而不稳。七十年代平均亩产皮棉62.67斤,其中1979年只有40.3斤,从1980年以后,由于认真落实党中央国务院的一系列植棉政策,实行科学植棉,大搞育苗移栽。四年来,棉花产量持续上升,1980年亩产皮棉85.8斤,1981年亩产皮棉111.5斤,1982年亩产皮棉129.4斤,1983年亩产皮棉145.3斤,四年平均递增19.19％。在1983年增产中,其中有5985担皮棉,是通过改制钵子的直径而取得的。就是将原来钵子直径5.5厘米,高9厘米的小营养钵,改成直径为7.5厘米,高12厘米的大营养钵,因此,改制后棉花在生理生态上,具有五大特点:一是钵子体积大适应苗龄长,叶片多,根系发育好;二是改小苗(2叶一心)为大苗(4—5叶)移栽;三是大苗移栽,抗植伤能力强,成活率高;四是大钵苗利于加快生育进程,缓苗期短,生长快;五是花芽分化已在
Our county annual cotton floor area of about 100,000 mu, is a middle-cotton-producing counties in Jiangsu Province, the past cotton production, has been low and unstable. In the 1970s, the average mu yield was 62.67 kg, of which only 40.3 kg in 1979. Since 1980, due to earnestly implementing a series of cotton planting policies of the Party Central Committee and State Council, scientific cotton planting has been carried out and seedlings planted. In the past four years, cotton output continued to rise. In 1980, 85.8 kg of lint per mu was produced, 111.5 kg of lint per mu in 1981, 129.4 kg of lint per mu in 1982 and 145.3 kg of lint per mu in 1983, an average increase of 19.19% over four years. Among the increase in production in 1983, of which 5,985 camel cottons were obtained through restructuring the diameter of the bowl. Is the original bowl diameter 5.5 cm, 9 cm high small bowl, into a diameter of 7.5 cm, 12 cm high nutrition Bowl, therefore, the cotton after the reform in the physiological and ecological, with five major characteristics: First, the large bowl volume Adapt to the long seedling age, more leaves, root development is good; second change seedlings (2 leaves one heart) for the seedlings (4-5 leaves) transplanting; Third, transplanting seedlings, anti-plant injury ability, high survival rate; Fourth Large bowl seedlings help to speed up the process of fertility, Huanmiao short, fast growth; Fifth flower bud differentiation has been
