本文是对三年来茄果类蔬菜地膜覆盖栽培的试验总结。通过实际观察,证明地膜覆盖栽培可提高地温3—5℃,并能保水抗旱防涝,提高土壤肥效,有利于蔬菜根系的发育,从而提高早期产量与总产量。对青椒“三落”有一定的抑制作用,可比对照增产50—80％,番茄可增产20—40％,茄子可增产50—60％。地膜覆盖栽培,方法简便,成本低廉,是有利于推广的一项新技术。
This article is a summary of experiment of plastic film mulching of solanaceous vegetables in three years. The actual observation shows that plastic film mulching cultivation can increase the ground temperature by 3-5 ℃, maintain waterlogging, prevent waterlogging and improve soil fertility, which is beneficial to the development of vegetable roots and thus improve the early yield and total yield. Green peppers, “three down” have a certain inhibitory effect, yield 50-80% more than the control, tomato can increase 20-40%, eggplant can increase 50-60%. Film mulching cultivation, method is simple, low cost, is conducive to the promotion of a new technology.
