近几年来,我省棉产区有的社队把泰兴黑豆套种在麦田里,再在豆田里套种棉花,逐步形成了“麦豆棉”三熟制。一、好处 (一) 增产增收:肖港公社丰胜大队从1975年实行“麦豆棉”三熟制,并在大面积上进行了“麦豆棉”三熟制和“麦棉”两熟制对比试验。三熟制平均每亩收粮食386.5斤(早熟3号大麦),泰兴黑豆160.9斤,皮棉215.4斤;两熟制平均每亩收粮食436斤,皮棉206斤。如果把豆算作粮,三熟制则多收粮111斤,多收皮棉9.4斤。 (二) 增加油料和饼肥:100
In recent years, some of the cotton production areas in our province have inter-planted Taixing black beans in the wheat fields and then planted cotton in the bean fields to gradually form a “three-cropping system” of wheat and cotton. First, the benefits (a) increase production and income: Fenggang brigade in Xiao Gang commune since 1975, “wheat bean” three cooked system, and in a large area on the “wheat bean” three ripening system and “wheat cotton” two cooked Comparative test system. The average yield per mu for the three-cropping system is 386.5 kg (barley aged 3), 160.9 kg for Taixing black bean, and 215.4 kg for lint. The average yield per mu for double-cropping system is 436 kg for grain and 206 kg for lint. If the beans count as food, more cooked rice is cooked 111 pounds, more than 9.4 kg cashmere. (B) increase oil and cake fertilizer: 100
