在毛主席革命路线的指引下,我们组织了工人、工农兵教师、学员三结合的实验小组,进行了棉花丰产试验,获得了亩产皮棉224.3斤的较好收成。试验面积一亩,土质为垅田胶泥土,中壤偏重,肥力中等,前作水稻。72年3月用牛翻耕两次,深度约6寸左右。耕地前每亩施土渣肥25000斤,过磷酸钙70斤。品种为4101(衣分39.6％)。3月13号播种,营养钵保温育苗,4月17日大小苗分类移栽,计划密度每亩5,000株,厢宽8尺,行距2尺。整个生育期内中耕松土8次,培土两次,灌溉5次,及早整枝,彻底治虫,棉株长势良好。由于该田为水改旱,耕层较浅,土壤粘重板结,影响棉花根系发育,造成早衰。现将经验初步总结如下。一、突出早字、狠抓管字
Under the guidance of Chairman Mao’s revolutionary line, we organized a combined experimental group of workers, workers, peasants and soldiers, and trainees to conduct a cotton yield experiment and obtain a good yield of 224.3 kg of mule per mu. Test area of an acre, soil for clay soil, medium-heavy, medium fertility, before the rice. 72 years in March with cattle plowing twice, the depth of about 6 inches. Acre soil fertilizer 25000 kg per acre before arable land, 70 kg of superphosphate. Variety 4101 (clothing points 39.6%). March 13 seeding, nutrition bowl seedling incubation, April 17 size seedlings transplanted planted density of 5,000 per acre, car width 8 feet, spacing 2 feet. Tillage 8 times throughout the growing period, earth twice, irrigation 5 times, early pruning, complete pest control, cotton plant grows well. As the field of water to drought, shallow plow, soil sticky compaction, affecting cotton root development, resulting in premature aging. The experience is summarized as follows. First, highlight the early word, pay close attention to the word
