地膜覆盖栽培是一项新兴而重要的农业技术措施。大量的农业生产实践证明,地膜覆盖具有增温、保墒、改善土壤理化性状等作用,因而可以促进作物正常生长,获得早熟、高产、优质的效果。尤其在北方生育期较短的地区,增产增收的效益更为明显。但是地膜覆盖栽培也要配合一定的条件,才能达到预期的目的。否则效果就会降低,甚至得不偿失。因此在实行地膜覆盖栽培时,应注意以下八忌: 一忌不选地 地膜覆盖栽培应选择具有中等或中等以上肥力的地块,并应具有浇水条件。不能选择沙土地、二洼地及坡地。
Film mulching cultivation is a new and important agricultural technology measure. A large number of agricultural production practices have proved that plastic film mulching has the functions of increasing temperature, preserving soil moisture and improving the physical and chemical properties of soil, and thus can promote the normal crop growth and achieve the effect of early maturity, high yield and good quality. Especially in the northern region where the growth period is short, the benefits of increasing output and increasing income are even more obvious. However, the film mulching cultivation must also meet certain conditions in order to achieve the desired purpose. Otherwise the effect will be reduced, or even outweigh the benefits. Therefore, in the implementation of plastic film mulching, should pay attention to the following eight bogey: Avoid whether to choose plastic film mulching should choose medium or medium fertility plots, and should have watering conditions. Can not choose sand land, two depression and slope.
