🌱 间作

在同一块田地里同时种植两种或两种以上的作物。

间作

间作是指在同一块田地里同时种植两种或两种以上的作物。作物行可以交错种植,也可以一种作物填补另一种作物之间的空隙。

这种做法与农业本身一样古老。玉米、豆类和南瓜一起种植,被称为美洲原住民农业的“三姐妹”,就是一个经典的例子。豆类攀爬在玉米秆上固氮;南瓜匍匐生长,遮蔽杂草。每种作物利用的光照、水分和根系空间都不同。

农民为什么这样做

间作会使后续环节变得复杂。两种作物共用一块田地,播种、喷洒农药和收割都会变得更加困难。因此,间作在规模较小、劳动密集型的农场中盛行,而在大型机械化农场中则举步维艰。

    My family has been intercropping beans and corn for generations. It's just how we've always done it, never knew there was a specific term.

    Does intercropping actually improve yield or is it more about pest management and soil health? I've read conflicting things.

    This is basically the opposite of modern monoculture farming. Interesting how traditional methods are coming back into fashion.
