【摘要】 1999～ 2 0 0 0年于惠州梅菜原产地兼主产区—土桥进行了梅菜地膜覆盖栽培试验。结果表明 :该栽培法和常规栽培相比 ,土壤温度、土壤含水量、土壤有机质含量和土壤孔隙度分别提高 5 7℃、 2 6 5 %、 4 1 17%和 17 14 % ,移栽后幼苗成活时间提早 4d ,移栽后一个月幼苗株高和株幅分别提高16 0 %和 5 1 6 % ,产量提高 2 9 8～ 5 8 3% .更多还原

【Abstract】 During 1999～2000, the method of covering soil with plastic film in Meicai culture was tested in Tuqiao-the original place and main production region of the crop in HuiZhou. It was found that, by using this method, the soil temperature?water content?organic matter content and porosity could respectively be raised 5.7℃?26.5%? 41.2% and 17.1%. The seedling survived 4d earlier, and, one month later, it was 16.0% higher and 51.6% wider than common seedling. The production could increase 29.8～58.3%.更多还原
