大多数蔬菜根系分布较浅 ,对土壤含水量反应极为敏感 ,南方地区雨水较多 ,地下水位高 ,土壤上层积水 ,渍害严重 ,造成土壤水肥气热失调 ,经常引起蔬菜秧苗沤根和烂根 ,导致蔬菜显著减产甚至绝收。为探索蔬菜基地防渍新思路 ,近年来 ,我们在蔬菜基地采用埋设地下暗管的方法调节? Most of the vegetable root distribution is shallow, very sensitive to soil moisture response, the southern rainwater more, groundwater level is high, the upper soil water, serious soil damage, resulting in soil water and fertilizer gas heat imbalance, often caused by vegetable seedling roots and rotten Roots, resulting in a significant reduction of vegetables even absolutely. In order to explore the new ideas of vegetable base stain-proofing, in recent years, we use the method of planting buried underground tube in the vegetable base?
