高粱是我县主要粮食作物之一,一般每年播种四十万亩左右,占春田面积60%。在生产上表現抗災稳收,能調节茬口,錯开农活,培养地力,籽实、稭秆用途广泛,群众习慣种植。目前,高粱单位面积产量不高,缺苗是重要原因之一。缺苗严重的需要重种、改种、补种或套种其他作物;缺苗一般的則不能充分利用地力和日照,影响产量。根据历年統計,高粱缺苗情况列表如下(表一)。 Sorghum is one of the main grain crops in our county, generally planting about 400,000 mu per year, accounting for 60% of the spring field. Displaced in the production of disaster-resistant steadily, can adjust stubble, stagger agricultural work, cultivate fertility, seed, straw use a wide range of habits of people planting. At present, sorghum yield per unit area is not high, lack of seedlings is one of the important reasons. Lack of seedlings need serious seed replanting, replanting or intercropping of other crops; lack of seedlings generally can not make full use of fertility and sunshine, affecting the yield. According to the statistics over the years, the list of sorghum lack of seedlings is as follows (Table 1).
