近年来,棉区黄枯萎病发病率上升,面积逐年扩大,棉铃虫为害严重,给棉花生产带来很大损失,挫伤了棉农种棉积极性。为寻找棉花增产途径,我们对植物有机营养素进行了试验,取得了良好的效果。邢台县南石门乡分别在初蕾期、盛花期、吐絮期喷施,浓度500倍液,亩产皮棉84.15公斤,比对照增产27.02％。1994年威县示范2万亩,平均亩产籽棉230公斤,比对照增产23％。抗枯萎病能力显著增强,据调查,连喷三遍的控制住了枯萎病发展,并恢复了正常。
In recent years, the incidence of yellow blight in the cotton area has risen, and the area has been expanding year by year. The serious damage to cotton bollworm has caused great losses to cotton production and dampened the enthusiasm of cotton growers. In order to find ways to increase yield of cotton, we tested the plant organic nutrients and achieved good results. Shimen Township, Xingtai County, respectively, in early buds, full bloom, bolting floculation period, the concentration of 500 times liquid, 84.15 kg of lint per mu, an increase of 27.02% over the control. Weixian demonstration of 2 million mu in 1994, the average yield of 230 kg of seed cotton, 23% more yield than the control. Fusarium wilt resistance was significantly enhanced, according to the survey, even spray three times control the development of blight, and returned to normal.
