目前全国棚室瓜果类蔬菜生产迅猛发展。但是由于棚室为固定设施,连茬使用着棚室内的有限土地。因此形成茬次频繁,大量增施有机肥难度大,导致棚室内土壤肥力下降。并且由于菜农增加化肥的用量,导致土壤孔隙度减少,地表板结,严重阻碍着土壤中微生物的活动,从而棚室瓜果蔬菜表现根系活性差,茎蔓发育不良。果实品质、产量都受到影响。笔者为解决这一问题,在棚室内做一养土增温耕作技术试验,取得明显的效果。
At present, the production of greenhouse fruits and vegetables in the country is growing rapidly. However, as the shed is a fixed facility, the stubble uses limited land within the shed. Therefore, the formation of stubble frequently, a large number of additional organic fertilizer difficult, leading to shed indoor soil fertility decline. And because vegetable farmers increased the amount of fertilizers, resulting in decreased soil porosity, surface compaction, seriously hindered the activity of soil microorganisms, so that the greenhouse vegetables and fruits show poor root activity, stalks and vines dysplasia. Fruit quality, yield are affected. In order to solve this problem, the author did a experiment to raise soil temperature in tilling room and achieved obvious results.
