浙江瑞安县马屿区因地制宜推广了春大豆→水稻→小麦连作的三熟制和络麻→水稻→油菜连作的三熟制,获得了显著增产。现将以上两种耕作制的增产效果,栽培技术分别介绍如下:春大豆→水稻→小麦连作一年三熟制春大豆与水稻连作在马屿区栽培已有多年历史,农民称之为豆通(意即大豆种后通田插水稻)。全区有10,000多亩土壤瘠薄的稻田,加上冬种小麦的影响,每年大熟只能种一季晚籼稻,俗称单插田。几年来,当地农民利用瘠薄 Zhejiang Province Ryu County Mayu based on local conditions to promote the spring soybean → rice → wheat continuous cropping three lines and Ma flax → rice → Rape continuous cropping system, access to a significant increase. Now the above two kinds of farming system yield effects, cultivation techniques were introduced as follows: Spring soybean → rice → wheat continuous cropping year Three-year-old spring soybean and rice continuous crop cultivation in the Mayu area has many years of history, peasants called bean (That is, after the soybean Tongtian inserted rice). The region has 10,000 acres of barren soil in paddy fields, coupled with the impact of winter wheat, annual ripening can only plant a season late indica rice, commonly known as a single field. For years, local farmers have been using barren land
