水地棉花产量不稳定,例如地处泾惠灌区中心的高陵县通远公社火箭大队,2,000亩棉花,1970年亩产皮棉44.4斤,71年69.5斤,72年71斤,73年122.1斤,74年75.6斤,76年54.6斤,77年75斤,78年122.3斤(测产)。水地棉花亩产低于100斤,经济收入不如粮食或其他经济作物。该大队73年以来3,000亩粮田,亩产都在千斤以上,产值120元以上。棉花是经济作物,其经济收入低于粮食作物,怎能调动社员种棉花的积极性呢?所以,研究水地棉花栽培技术,首先要研究棉花亩产100斤、120斤以上的稳产栽培技术。在实践中深感棉花生产受自然气候条
Water cotton yield is unstable, for example, the Tongyuan commune rocket unit in Gaoling County, located in the center of Jinghui Irrigation District, has 2,000 mu of cotton, 44.4 kg of lint per mu in 1970, 69.5 kg in 71 years, 71 kg in 72 years and 122.1 kg in 1973, 74 years 75.6 pounds, 76 years 54.6 pounds, 77 years 75 pounds, 78 years 122.3 pounds (measured output). Water cotton yield less than 100 pounds per mu, economic income is not as good as food or other cash crops. Since its establishment in 1973, the brigade has 3,000 mu of grain fields, each producing over 120 kilos of grain and producing more than 120 yuan of output value. Cotton is a cash crop, its economic income is lower than food crops, how to mobilize the enthusiasm of members of cotton? So, to study cotton water cultivation techniques, we must first study the cotton yield of 100 pounds, more than 120 pounds of stable cultivation techniques. In practice, cotton is deeply affected by natural climatic conditions
