实行双油制,即油菜～花生一年两熟轮作制,是发展我县花生生产的重要途径。1986年全县双油制推广面积达14,950亩,占花生总面积的54.4％。 一、发展双油制是发展花生生产的必然趋势 (一)发展双油制,是耕作改制的需要,是农民的自觉要求。 我县历史上花生生产是以一年一熟的春花生为主,近三十年来,由于修水利,种绿肥,水稻面积已扩大至65万亩,而花生面积则由1955年的18万亩压缩到不足3万亩,尤其是春花生面积仅剩4,570亩,只占16.6％。且大部分集中在一片三线(涟淮片、废黄河线、张河线和盐河线)的沙地薄地,花生单产一直在100公斤上下波动。
The implementation of double oil system, that is, rape ~ peanut crop rotation system for two years a year, is an important way to develop peanut production in our county. In 1986 the county double oil system to promote an area of 14,950 acres, accounting for 54.4% of the total area of peanuts. First, the development of double-oil system is an inevitable trend in the development of peanut production (A) The development of double-oil system is the need of farming and restructuring and is consciously required by peasants. The history of peanut production in our county is mainly based on spring peanuts cooked in one year. In the past three decades, the area of paddy has been expanded to 65 million mu because of water conservancy and green manures, while the peanut area has increased from 18 million mu Compressed to less than 30000 acres, especially the spring peanut area of only 4,570 acres, only 16.6%. And most of them are concentrated in the thin sandy land of a third line (Lianhua Huai, Huanghe River, Zhanghe River and Yanhe River). Peanut yield has been fluctuating up and down by 100kg.
