改革耕作制度是充分利用自然资源,解决用地养地、改善生态系统,发展农业生产的一项措施。为此,我们在过去棉粮,棉油间作的基础上,又对棉田间作绿肥的配置形式及后效进行研究。实践证明,它不仅能培肥地力,改良土壤,而且能在三年交替循环中,达到增产增收,在目前土壤肥力普遍下降的情况下,有一定的现实意义。一、研究内容1.1.2尺等行距隔—垄棉花种—垄柽麻。2.1.2尺等行距隔两垄棉花种—垄柽麻。3.2尺大垄垄沟内套种柽麻。4.1.5尺等行距隔—垄棉花种—垄柽麻。
Reforming the system of farming is a measure that makes full use of natural resources, settles land for cultivation, improves ecosystems and develops agricultural production. Therefore, on the basis of past cotton and cotton intercropping, we also studied the configuration and effect of green manures in cotton fields. Practice has proved that it can not only fertilize soil fertility and improve the soil, but also in three years of alternating cycles, to increase production and income in the current decline in soil fertility generally have some practical significance. First, the research content 1.1.2 Ruler line spacing - ridge cotton species - Ridge ridge linen. 2.1.2 feet and other rows spaced two ridge cotton varieties - Ridge ridge Ma. 3.2 feet wide furrows ridge furrow hemp intercropping. 4.1.5 feet and other line spacing - ridge cotton varieties - Ridge ridge Ma.
