高粱坐苗的发生与年份(水分、温度)土质、地势、品种和茬口有关,主要是土壤瘠薄、严重缺磷和苗期低温所引起的.从长远的观点看,提高土壤肥力是防治高粱坐苗的根本措施.当前对一些易发坐生苗地块,只能采取综合措施,排除诱发因素,加以预防.1.提高土壤肥力,是防治高粱坐苗的根本措施.据调查,高粱坐苗普遍发生在低产地块.这些地块,土壤严重缺氮、缺磷,有机质含量低,土壤干、 The occurrence of sorghum seeding is related to soil quality, topography, variety and stubble in year (moisture and temperature), mainly caused by soil infertility, severe phosphorus deficiency and low temperature at seedling stage. In the long run, increasing soil fertility is the key to preventing and controlling sorghum The basic measures of seedlings.Currently for some prone-sowing plots, only to take comprehensive measures to eliminate the predisposing factors, to be prevented.1.Improvement of soil fertility, is the fundamental measure to control sorghum sitting seedlings.According to the survey, sorghum sitting seedlings Commonly occurred in low-yield plots of these plots, the soil is a serious lack of nitrogen, phosphorus deficiency, low organic matter content, dry soil,
