棉花间作春甘蓝的方式及效益研究

PATTERNS AND BENEFITS OF INTERCROPPING COTTON WITH SPRING CABBAGE

本试验研究了棉花间作春甘蓝的方式、效益及配套栽培技术。结果表明,在保证棉花不减产的前提下,棉花间作春甘蓝亩增收1546～2490kg春甘蓝,亩纯收益比单作棉花提高136.5～198.4%。非盐碱棉田的间作方式2∶2(2行棉花间作2行春甘蓝)和1∶1(1行棉花间作1行春甘蓝)均可;盐碱棉田宜采用2∶2的间作方式。露地栽培春甘蓝的育苗时间为元月上旬;最佳移栽时间为3月底至4月初;最优移栽苗龄为8叶苗龄;最适密度为3000株/亩;适宜品种为中甘11号。

Intercropping cotton with spring cabbage could ensure normal yields of cotton and got an additional yield of 1546～2490kg of spring cabbage per mu. The net income from intercropping per mu was 136.5～198.4% higher than that from sole cotton cropping. In the no-saline-alkali cotton fields, patterns of intercropping in 1:1 (each cotton row followed by one row of spring cabbage) and 2 : 2 (every two cotton rows followed by two rows of sp ring cabbage) were suitable. However, in the saline alkali cotton fields, the intercropping pattern in 2 : 2 did well. The seedling-raising time of spring cabbage was the first ten-day period of January. The most adaptable transplanting period was from the end of March to early April. Seedlings with 8 leaves were the most suitable for transplanting. The appropriate density was 3000 plants per mu and the adapted variety was Zhonggan 11.
