杂交早稻“一季加再生”的高产品种(组合)筛选试验

[目的]探索实施油-稻-稻不足、一季稻-油菜有余的地区推广早稻＋再生稻＋油菜种植模式的可行性和经济效益.[方法]开展早稻再生稻栽培试验.[结果]陵两优268和陵两优104具有效分蘖多、再生能力强、穗大粒多、结实率高等优势,且两季产量均比对照显著增产,可作为早稻＋再生稻＋油菜3熟栽培优选品种,进一步开展试验示范.[结论]该研究可为提高双季稻的比例同时促进油菜生产提供科学依据.

Screening Test on High-yielding Varieties and Combinations Hybrid Rice of a Season with Regeneration

[ Objective ] The aim was to explore the feasibility and economic benefit of the planting model in promoting early rice ＋ regeneration rice ＋ rape in the region of the surplus area of one season paddy rape and cole, and the oil - rice - rice shortage in rice producing areas. [ Meth- od] The early rice and ratooning rice cultivation trail was conducted on. [ Result] Test results showed that Linliayou 268 and Linliayou 104 had many advantages of the more effective tillers, the regeneration ability, the large spike number, seed setting rate higher, and the two season＇ s yield were significantly increased comparing with control, so it could be used as the three cultivation species preferred of early rice and ratoon rice and rape, to carry out the test demonstration. [ Conclusion] The study provides a scientific basis for improving the ratio of two season rice and promoting rape production.
