旱地复种方式在人多地少、光热资源丰富,经济贫乏的丘陵地区必然向多熟、多样力向发展。目前,早地多熟复种方式存在着两个较为突出的问题:一形式较单一,山上是麦—苕、豌—苕两熟制,山下是麦/玉/苕三熟带状复种制,经作物争地矛盾很突出;二是多熟下的组合配套不尽合理,产量不高不稳。 Dryland multiple cropping in less people, rich in light and heat resources, poor hilly areas will inevitably to more cooked, diversified development. At present, there are two prominent problems in the early multipurpose and multi-cropping system: one is simpler, the other is wheat-pomfret and peas-pomfret, while the foot of the mountain is wheat / jade / Contradictions in the fight for crops is very prominent; Second, under the combination of multi-cooked unreasonable, the output is not high and unstable.
