麦田间作春甘蓝的生长发育特性

麦田间作春甘蓝，小麦对间作甘蓝产生遮荫，使其田间光照显著减弱，地温降低、湿度增大。与单作甘蓝相比，间作甘蓝生长发育特性主要表现为：球叶合抱力下降，球叶数减少，外叶数增多，同时叶片光合速率降低，总干物质积累减少，尤其是向叶球的干物质分配减少，最终经济产量较单作降低２５．７％。提高间作甘蓝产量的关键是采用早熟品种和早熟栽培措施

Studies on Growing Characteristics of Intercropping Cabbage with Wheat

Intercropping spring cabbage with wheat, cabbage was in the shade of wheat and had poor ecological conditions with significantly low light intensity, soil temperature and high air humidity. As compared with single cropping cabbage, intercropping cabbage had the more rossette leaves and the fewer heading leaves, the lower photosynthetic rate, the less total dry matter accumulation and the ratio of dry matter distribution to heading leaves. The yield per 667m2 for intercropping cabbage decreased 25.7% than single cropping. Using early mature variety and early mature culture methods can increase the yield of intercropping cabbage.
