花生地面覆盖塑料薄膜,是一项新的高产栽培方法,也是一项防御低温冷害的有效措施。我县从1979年开始试验,1980年又进行了多点试验、示范,均收到了显著的增产效果。1980年试验、示范点11个,面积共144.9亩,平均每亩增产荚果160.4斤,增产36.2%。平均计算,每亩可增加收入55.14元。此外,这种栽培方法还可提高饱果率和出仁率,并可省去除草、铲趟和清棵的用工。 Peanuts ground plastic film, is a new high-yield cultivation methods, but also an effective measure to prevent cold damage. Our county began to experiment from 1979, carried out more experiments in 1980, and demonstrated that they both received significant increase in production. In 1980, there were 11 demonstration sites with a total area of ​​144.9 mu, with an average yield of 160.4 kg of pod per mu, an increase of 36.2%. On average, it can increase income by 55.14 yuan per mu. In addition, this cultivation method can also improve the rate of full fruit and kernel rate, and eliminating the need for weeding, shoveling trips and clearing trees.
