目前菜农除用薄膜覆盖技术外,还在春地保温防冻越冬方面作文章。笔者1993年在孔宅村与菜农一起搞了春地秋耕保温防冻提早定植试验。 试验方法:收完秋茬蔬菜后,把地通耕20cm深,使地略休闲,然后按早春需栽培蔬菜品种打好行距,将行距用小施拉机开沟深25cm—30cm左右。把预先备好的有机肥按每亩5000kg施入沟内,淡小水,粪用土压实,土 At present, farmers in addition to using thin-film technology, but also in the winter heat insulation winter overwinter article. In 1993, I made a trial on the early planting of the autumn ground-holding and freezing-thawing in spring in Kongzhai Village and vegetable farmers. Test Method: After harvesting autumn stubble vegetables, tillage 20cm deep, the ground slightly leisurely, and then according to the early spring need to cultivate vegetable varieties to lay the line spacing, spacing will be small with a deep drawing machine ditching 25cm-30cm or so. The pre-prepared organic fertilizer 5000kg per mu into the ditch, light water, soil compaction, soil
