大豆是一种生长期短、比效耐阴抗倒的作物,对其他作物的田间管理影响较小。大豆根瘤又能因氮,种植大豆还能养地,因而短合于与多种作物,果树间作套种;大棵作物间套种大豆还能减轻草害,既省工,又能保土。1.大豆与玉米间作大豆与玉米间作是黄淮海地区主要的间作形式之一。大豆为豆科作物,直根系,株矮叶小,本身寄生有根瘤艻可以因氮,是需磷、钾较多的作物。玉米为禾本科作物,须根系,株高,叶大而长,属喜氮需肥需水
Soybean is a crop that has a short growth period and is more effective than shade-tolerant crops and has less impact on field management of other crops. Soybean nodules can also be due to nitrogen, soybean cultivation can also be short, so short with a variety of crops, fruit intercropping; intercropping large crop of soybean can also reduce grass damage, both labor, but also soil conservation. 1. Soybean and maize intercropping Soybean and maize intercropping is one of the main intercropping forms in Huang-Huai-Hai region. Soybean leguminous crops, straight roots, plants, short leaves, parasitic nodules can be due to nitrogen, phosphorus, potassium more crops. Corn is a gramineous crop, fibrous roots, plant height, large and long leaves, is a need for water, nitrogen fertilizer
