随着植棉技术的进步,棉花施肥技术也在不断的发展。由五十年代以农家有机肥为主到六十年代的重施氮化肥,发展到现在苗轻、蕾控、重施花铃肥,NPK 三要素配比施用,棉花产量也在不断提高。当前棉花施肥配比中一般是苗期多用NP 肥,蕾期以后配合钾肥施用,苗期施钾极少。我们根据棉农历史上用草木灰拌种习惯,在当地农民试用钾化肥拌种的启示下,于1984—1985年进行了氯化钾拌棉种对棉苗素质影响的试验,取得了壮苗、抗病、早发的显著效果。1985
With the progress of cotton planting technology, cotton fertilization technology is also unceasing development. From the 1950s to the farmers of organic fertilizer to the sixties of the re-application of nitrogen fertilizer, developed to the present light, bud control, re-implementation of Hu Ling, NPK three elements ratio of application, cotton production is also rising. The current ratio of cotton fertilization is generally used more NP seedling seedling stage, with the application of potash after the budding stage, very little seedling application of potassium. According to the history of cotton farmers with straw ash seed dressing habits, local farmers try potassium seed dressing enlightenment, carried out in 1984-1985 cotton chloride cotton varieties on the quality of cotton seedlings trials, and achieved strong seedlings, anti-aging Sick, early onset of significant effect. 1985
