冬闲田白菜薹免耕和翻耕栽培比较试验

利用水稻冬闲田对白菜薹进行免耕和翻耕栽培比较试验，设计了免耕留蔸15 cm、免耕留蔸35 cm和机械翻耕（CK）3个处理，比较了白菜薹的生产成本、移栽成活率、前期产量和总产量。试验结果表明，2种栽培方式下白菜薹总产量无显著差异；免耕栽培的生产成本高于机械翻耕栽培；综合来看，在面积较小或地形限制等不方便采用机械翻耕的条件下，可利用水稻冬闲田进行白菜薹免耕栽培。

Effects of No-tillage Cultivation on Cabbage Sprouts in Winter Fallow Field

In the paper, we compared the effects of no-tillage cultivation (with rice straw height of 15 cm and 35 cm respectively) and mechanical tillage cultivation on the production cost, transplanting survival rate, early-stage yield and total yield of cabbage sprouts which were cultivated in winter fallow field. The results showed that, the two kinds of cultivation methods had no significant difference on total yield, and the production cost of no-tillage cultivation was higher than mechanical tillage cultivation. We could use the no tillage cultivation to produce cabbage sprouts in winter fallow field, on the condition that it was not convenient to use mechanical tillage cultivation because of the terrain restriction.
