玉米搞地膜覆盖栽培,增产效益十分显著。1986年111团二连李淑敏在138亩田中种了50亩地膜玉米,裸地栽培88亩。除覆膜外,其它技术措施相同。地膜玉米总产达45025公斤,单产900.5公斤;裸地88亩,共收55000公斤,单产625公斤。地膜玉米较裸地玉米增产275.5公斤;亩产值增加99.18元,虽然亩多投入25元,但亩利增加74.18元。玉米搞地膜覆盖,经济效益明显提高,为玉米高产开创了新的路子。 试验中我们体会到,地膜栽培好处很多,主要有以下五条:
Maize mulch cover cultivation, yield increase is very significant. In 1986 111 group Erlian Shu-Min Lee in 138 acres of field planted 50 acres of plastic corn, 88 acres of bare land cultivation. In addition to filming, the other technical measures the same. The total output of plastic film corn 45025 kilograms, yield 900.5 kilograms; bare land 88 acres, a total of 55000 kilograms, yield 625 kilograms. Mulched corn increased 275.5 kilograms more than bare land corn; the output value per mu increased 99.18 yuan, although the mu more invested 25 yuan, but the profit increased 74.18 yuan. Maize engage in plastic film coverage, economic benefits improved significantly, creating a new way for high yield of corn. We experience in the experiment, a lot of benefits of plastic film cultivation, mainly in the following five:
