| 摘 要： | 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。

| Abstract: | Based on two—year field experiment, this study consistes of three planting systems and four kinds of ptastic film used to mulch the ground for seed production of Brassica pekinensis Rupr. The study was conducted in Taigu, Shanxi. The planting systems involved seed production from(ⅰ) seedlings planted directly (ⅱ) transplanting seedlings, and (ⅲ) mature plants. The study we have performed showed that no matter what planting systems were used the plastic film mulching on the ground raised the seed yield of B. pekinensis by about 30％; and seed qualities such as 1000—grain weight and eolour and lustre were improved. The study also shows that both polyethylene and potyvinyl chloride were favourable covering material. |
