低酚棉亦称无毒棉,其棉饼、棉油、棉秆、棉叶不经脱毒即能食用或饲用。棉籽富含蛋白质、脂肪,有较高的利用价值。我县自1986年引种试验,4年累计示范3.54万亩,平均亩产皮棉60.46公斤,总经济效益22.73万元,并总结出其丰产配套栽培技术。一、选用高产、优质、多抗品种我们经4年多层次试验、示范,在45个低酚棉品种(系)中,筛选出具有适应性广、抗枯黄萎病、高产优质品系石无16。该品系株型半松散,生育期125天,属中晚熟品种。籽指10.5克;单株结铃性强,铃重达5.3克;衣分平均40.3%,绒长平均295毫米。易出苗,苗蕾期生长快,后期早熟不早衰,而且抗枯黄萎病、耐蚜虫,丰产性强。4年9处试验,其中4处第一、
Low-phenol cotton, also known as non-toxic cotton, the cotton cake, cotton, cotton stalks, cotton leaves can be eaten without eating or feeding. Cottonseed is rich in protein, fat, has a high value. My county since 1986, introduction of the test, 4 years cumulative demonstration of 35,400 mu, an average of 60.46 kilograms of lint per mu, the total economic benefit of 227,300 yuan, and summed up its high yield and supporting cultivation techniques. First, the selection of high yield, high quality, multi-resistant varieties We tested after 4 years of multi-level demonstration of 45 low-phenol cotton varieties (lines), screened with wide adaptability, resistance to Verticillium wilt, . The strains are semi-loose plant type, growth period of 125 days, is a middle-late maturing varieties. Seeds refer to 10.5 grams; single boll bell, boll weight of 5.3 grams; clothing average 40.3%, velvet length average 295 mm. Easy to emerge, the rapid growth of seedling bud stage, early premature aging is not premature, but also resistant to Verticillium wilt, resistant to aphids, high yield and strong. 4 years 9 trials, of which 4 first,
