间作套种是我国农业生产的传统经验,是充分利用地力、光能、热能资源的有效形式,是增加复种的有效措施之一。间套作方式在我国南北方都普遍存在,并且面积大、效果好,尤以早作更明显。间(套、混)作作物的搭配原则是:(1)高秆喜光作物与矮秆耐荫作物,如向日葵—小豆,玉米—木薯,玉米一花生等;(2)浅根系作物与深根系作物:如黄花茅(Anthoxanthnm odoratum)牧草—长叶草前(Plantago lanceolata)药草;(3)豆科作物与非豆科作物;如高粱—菜豆(豆类),玉米—大、小豆,棉花—矮秆豆类等;(4)直立型作物与蔓性作物:如小麦—苕子,大豆—甘薯,玉米—甜瓜,高粱—红花等。
Intercropping intercropping is a traditional experience of agricultural production in our country and an effective form for making full use of geo-energy, light energy and heat energy resources, and is one of the effective measures to increase multiple cropping. Intercropping methods are common in both northern and southern China, and the area is large, the effect is good, especially as early as more obvious. The principle of collocation between crops is that: (1) high-quality hi-yield crops and dwarf shade-tolerant crops such as sunflower-adzuki bean, corn-cassava and corn-peanut; Crops such as Anthoxanthomodoratum pasture - Plantago lanceolata herb; (3) Legumes and non-leguminous crops; such as sorghum - beans (legumes), corn - large, adzuki beans, cotton - Dwarf legumes, etc .; (4) upright crops and trailing crops: such as wheat - razor clam, soybean - sweet potato, corn - melon, sorghum - safflower and so on.
