玉米覆盖地膜的高产栽培有着不推而广的发展趋势。但因地膜供不应求和成倍的涨价,势必要直接影响玉米地膜覆盖高产栽培技术的迅速发展。为此,辽宁西丰县农业技术推广中心,在1987年中,重点在房木乡并同房木乡农科站进行了玉米覆盖半幅膜的多点试验,均获成功,降低了成本,增加了经济效益。在万福、普安两个村三户科技示范户进行了8亩试验。将垅距59.4厘米三改二变为90厘米的畦作,上种穴距33—39.6厘米的双株紧靠或留小拐子苗,实行单向窗植,即二行并成一行种,上覆盖半幅膜(45厘米宽),透气覆盖面可达25—30厘米宽。这样在同样
Maize mulching film high-yield cultivation has not pushed the development trend. However, due to the shortage of mulching film and doubling prices, it is bound to have a direct impact on the rapid development of maize mulching cultivation techniques. To this end, Xifeng County, Liaoning Agricultural Technology Promotion Center, in 1987, focusing on Fangmu Township and Fangmu Township Agricultural Station conducted a multi-point test of corn covered half-film, were successful, reducing costs and increase the economy benefit. In Wanfu, Pu’an two village three families of technology demonstration households conducted 8 acres of test. The distance from 59.4 centimeters to three to two into 90 centimeters of work, on the seed point 33-39.6 cm from the two strains close to or stay small seedlings, the implementation of one-way window planting, that is, two lines and into a line, on the line Cover half the film (45 cm wide), breathable coverage up to 25-30 cm wide. This is the same
