再生稻与晚稻共生栽培,即是在中稻以后蓄留的再生稻田里套栽一季晚稻,实行两稻共生,同期收获。再生稻,晚稻共生(又称水稻2插3收)是针对中稻加再生稻地区1年内对自然资源不能充分利用,种植双季稻温光资源又不足,而且再生稻产量又不稳定的情况,为提高产量和土地利用率而研究出的一种新的稻田耕作制度。1990年在头季稻严重倒伏,晚稻又受长时间干旱的影响下,中稻、再生稻、晚稻三季合计亩产达到770.9～882.6公斤,比对照亩增产179.6～291.3公斤,增产30.37～49.26％。四川省泸县、纳溪、
Reproductive rice and late rice symbiotic cultivation, that is, after the middle-aged rice stored in regenerative rice fields planted late rice, the implementation of two rice symbiosis, the same period of harvest. Regeneration rice, late rice symbiosis (also known as rice 2 insert 3 received) is for mid-rice plus ratoon rice within one year can not make full use of natural resources, planting double rice temperature and light resources are not enough, and ratoon rice yield is not stable, A new rice farming system developed to increase production and land use. In 1990, under the influence of heavy lodging in the first season of rice and long time drought of late rice, the total output of mid-season rice, ratoon rice and late rice in the three season reached 770.9 ~ 882.6 kilograms, increased by 179.6-291.3 kilograms and 30.37-49.26% more than the control mu.
