【摘要】 为了研究金铁锁应用地膜覆盖栽培的效果,笔者采用白色农膜覆盖、黑色农膜覆盖、不覆盖任何农膜(CK)研究了金铁锁种子直播栽培的效果。结果表明:用地膜覆盖栽培比不盖膜栽培第1年可明显提高保苗率,增加根重;第2年保苗率明显降低,根重无明显差异;第3年保苗率和根重都明显降低。种植第1年可用农膜覆盖,种植第2、第3年不能再盖膜。3年连续盖膜栽培可导致金铁锁最终产量降低。更多还原

【Abstract】 The paper aims to study the cultivation effect of Psammosilene tunicoides W. C. Wu et C. Y. Wuunder plastic mulching. 3 treatments of white plastic mulching, black plastic mulching and cultivation withoutmulching were carried. The results showed that plastic mulching could significantly improve the survival rate ofseedling and increase the root weight in the first year. Compared with the cultivation without mulching, in thesecond year, the survival rate of seedling decreased significantly and the root weight had no significantdifference, but in the third year, the survival rate of seedling and the root weight both decreased significantly.Therefore, plastic mulching cultivation can be taken in the first year, but not in the second and the third year. 3years of consecutive cultivation under plastic mulching will lead to the final yield decrease.更多还原
