花生是我省大春主要油料作物,面积和产量均占80％以上。种植区域主要分布在丘陵地带,长期沿袭着传统栽培技术,加上土质瘦薄,自然灾害频繁,春季气温不稳定,播种时容易遭受低温寒潮和干旱影响,往往造成烂种炕芽,缺窝缺苗严重,生育中后期又常遇伏旱和洪涝灾害袭击,产量很不稳定。为了改变这种状况,1982年引进了花生地膜覆盖栽培,经连续几年小面积试验、示范均获得成功,为花生稳产高产找到了一条可靠途径。近年来,为了深化花生地膜覆盖栽培技术,提高技术经济效益。在不同的生态区,进行了花生地膜覆盖栽培的配套技术研究,据13个重点示
Peanut is the major oilseed crop in spring in our province, with an area and output of over 80%. The planting areas are mainly distributed in the hilly areas, long-term follow the traditional cultivation techniques, coupled with thin soil, natural disasters, the temperature instability in spring, when seeding vulnerable to cold and drought, often causing bad kang buds, lack of nest Severe seedlings, fertile midsummer and often encounter drought and flood disasters, the output is very unstable. In order to change this situation, the peanut mulching cultivation was introduced in 1982 and succeeded in demonstrating for several years in a small area. It has found a reliable way for the steady and high yield of peanut. In recent years, in order to deepen the peanut plastic film mulching cultivation techniques, improve technical and economic benefits. In different ecological zones, peanut mulching cultivation techniques supporting technology, according to the 13 key show
