塔耳公社劳动大队今年有1,030亩红花草子普遍获得高产。其中亩产鲜草8,000斤以上的有280亩,6,000斤左右的570亩。除留种67亩外,963亩草子可肥田1,348亩。这个队红花草子高产的主要经验之一是积极推广草子和夏粮、夏油作物轮作。 近年来,这个队在逐步扩大三熟制的同时,将一部分原来的草子-双季稻田,实行草子和油菜、大麦或小麦轮作换茬。从而大大改善了土壤的理化性状,促进了草子的高产。我们在该队调查了21块草子高产田,亩产超过8,000斤的18块都是轮作的,其中12块是和油菜轮作的。由于轮作,土壤的速效养分显著提高(附表),不仅绿肥产量高,也有利于油菜或大、小麦的生长。
TAR commune labor brigade 1,030 acres of red flowers this year, the general access to high yield. Among them, more than 8,000 kilograms of fresh grass per mu has 280 mu and 570 mu of 6,000 kilos. In addition to remaining species of 67 acres, 963 acres of grass can be fertile fields 1,348 acres. One of the main experiences of the team’s high yield of safflower is to promote grass and summer crops and summer crop rotation. In recent years, while gradually expanding the three-crop system, part of the original grass-double cropping paddy field has switched its crop of grass and rape, barley or wheat. Thus greatly improving the physical and chemical properties of soil, promoting the high yield of grass. We surveyed 21 high-yielding weeds in the team and all 18 of the more than 8,000 kg per mu were in rotation, of which 12 were rapeseed. Due to rotation, soil available nutrients increased significantly (schedule), not only high yield of green manure, but also conducive to the growth of rape or big wheat.
