玉米和大豆间作是充分利用地力、光能和空间,提高二者总产量的好方法。但间作方式不同,产量表现也不一样;在以玉米为主间作物的前提下,大豆产量受间作方式的影响较大。一般的规律是,玉米行数愈少,大豆增产愈显著,大豆行数愈少,其产量愈低。究竟以那种间作方式为好,各地试验结果很不一致。事实上,因受气候、品种和栽培技术等条件的影响,各地的合理间作方式是不相同的。为了探索六盘水市自然条件和生产水平下,既不严重影响玉米产量而又利于大豆增产的间作方式,特进行了本试验。
Intercropping corn and soybeans is a good way to make full use of soil fertility, light energy and space and to increase the total output of both. However, the intercropping methods are different, and the yield performance is also different. Under the precondition that the main crops are corn, the soybean yield is greatly affected by the intercropping method. The general rule is that the fewer corn rows, the more significant the soybean yield, the less the number of rows of soybeans, the lower its yield. What kind of intercropping method is better, the test results across the inconsistency. In fact, due to the influence of climatic conditions, varieties and cultivation techniques, the reasonable modes of intercropping are not the same everywhere. In order to explore the natural conditions and production levels of Liupanshui city, neither seriously affect the yield of corn but also conducive to soybean intercropping mode, especially the test.
