为了提高大白菜(B. campestris ssp pekinensis.)种子的产量和质量,我们进行了两年地膜覆盖研究。结果表明:无论直播小株、育苗小株、老株那种采种方式,凡使用地膜覆盖的均比不覆盖的产量增加30％左右,质量也明显的提高;聚乙烯、聚氯乙烯都是良好的地而覆盖材料,在大白菜种子生产中可以取得相近似的效果。
In order to improve the yield and quality of B. campestris ssp pekinensis seeds, we conducted a two-year plastic film mulching study. The results showed that no matter the live seedlings, small seedlings and old seedlings were collected, the quality of mulching with plastic mulching increased by about 30% than the uncovered mulching, and the quality was also improved obviously. Polyethylene and polyvinyl chloride were all good Of the ground cover material, can produce similar results in the production of Chinese cabbage seeds.
