江苏宝山县长兴区种植绿肥大草(苜蓿),是该地小熟和大熟作物肥料的来源,所以绿肥收成的好坏,直接影响水稻的增产。1956年全面实行中稻改种晚稻,由于晚稻收获期过晚,不能适期下种苜蓿,给农业生产带来一个新的矛盾。而在晚粳稻田中间作大草(以下简称间作草),就能解决这个问题。现把长兴区潘石乡红星农业社第八队试种间作草成功的经验介绍于后,供参考。八队总耕地261.2亩,种间作草72.6亩,解决了79亩大田的肥料。据4月28日普查,
Changxing District, Baoshan County, Jiangsu Province, planting green manure (alfalfa) is the source of small and mature crop fertilizers in the area. Therefore, the harvest of green manures directly affects the increase of rice yield. In 1956, the full implementation of mid-season rice replanting late rice, late harvesting of late rice, can not planted under the kind of alfalfa, to agricultural production has brought a new contradiction. In the middle of late japonica rice fields for big grass (hereinafter referred to as intercropping grass), we can solve this problem. Now Changxing District Pan Shixiang Red Star Agricultural Corps eighth trial of intercropping grass success stories introduced for reference. Eight teams total 261.2 acres of arable land, planted 72.6 acres of grass, to solve the 79 acres of fertilizer field. According to the April 28 census,
