利用早稻田间作夏季绿肥——田菁,是一条自力更生开辟晚稻肥源的新途径,对夺取晚稻丰收促进全年平衡增产和培养地力都具有一定作用。1974年,我们在监利县与贫下中农相结合,开展早稻间作田菁的试验示范工作,全县间作田菁面积共2.5万亩。通过一年的进一步实践,对早稻间作田菁的栽培技术摸到了一些经验。现就以下三个问题总结如下。
The use of early rice field as a summer green manure - Sesbania is a new way to develop self-reliance on late-season fertilizer sources, which will play an important role in seizing the harvest of late rice and promoting balanced production and cultivating fertility throughout the year. In 1974, we Jianli County and poor middle peasants combined to carry out the early rice intercropping Tianjing experimental demonstration work, the entire county for the total area of 25,000 acres Tian Jing. Through one year’s further practice, some experience has been gained in the cultivation technology of the early-season rice cultivar Tian Jing. The following three questions are summarized below.
