我县八万亩棉花,其中平原一万亩、山区二万亩、丘陵五万亩左右。过去部份棉花苗期迟发,后期早衰,所以产量不高。一九七九年棉花后劲虽然较足,但忽视了后期防虫,预计每亩少收十斤皮棉;一九八○年约有三分之一的棉地因发黄叶枯死病和受红蜘蛛为害而早衰,这类棉地,每亩要少收二、三十斤皮棉。从多年的经验教训得出结论,要棉花高产,就要添后劲,防早衰,增结秋桃。(一)象我县这样的棉区能不能够增结秋桃夺高产?我们认为是能够的。首先,我县过去很多高产典型之所以增产,就是因为增结了秋桃。1、一九八○年,湓城公社庆丰大队第十生产队水改旱的棉花,分为后劲足、后劲一般和早衰的三种类型,经过检查测定,秋
My county 80,000 acres of cotton, of which 10,000 hectares of plains, mountainous area of 20000 acres, about 50000 acres of hills. In the past some cotton seedling late, late premature aging, so the yield is not high. Although the cotton stamina in 1979 was relatively adequate, it neglected pest control at the end of the year. It is estimated that it will receive a minimum of 10 pounds of lint per mu. About one-third of the cotton fields died of the yellow leaf blight in 1980 and the red spiders Premature damage to damage, such cotton, less per acre to receive two or three pounds of lint. From many years of experience and lessons learned, to high-yielding cotton, we must add strength, prevent premature senility, increase knot autumn. (A) As the cotton area like my county can not increase knot Autumn wins high yield? We think it is possible. First of all, the county in the past a lot of high yield typical reason to increase production, it is because of the increase of autumn peach. 1. In 1980, the tenth production team of Qingfeng Brigade in Yuncheng commune changed the drought-hardened cotton into three types: stamina, stamina and premature aging. After examination and determination, autumn
