粉垄早稻+再生稻亩产稻谷1000公斤种植模式可行性分析

利用粉垄农耕新技术,经粉垄栽培水稻试验表明,粉垄中低产稻田耕作层由传统耕作15—18cm增加到22—25cm,早稻利用超级稻组合种植产量达550—650kg/667m2,比传统耕作增产20%左右;粉垄水稻根系发达,早稻收获后作再生稻栽培,低位分蘖,每667m2产量可达400kg以上。据此分析了在广西双季稻地区尤其是发展秋冬种的地区,粉垄早稻+再生稻实现"一种两收"亩产稻谷1000kg,利用再生稻比晚稻提早成熟收获20—30d发展秋冬种高值种植的可行性。

The feasibility study of "smash-ridging" early rice + regenerated rice cultivation model

Using the technology of ＂smash -ridging＂, the study results show that this new technology has increased the soil - layer depth of paddy field from normally 15 - 18cm to 22 -25cm. The yield of early rice has reached 550 - 650kg per 667 m2 ,20% higher than CK with stronger root system. The re- generated rice after harvest of early rice has yielded more than 400kg per 667 m2, and could make a to- tal of 1000kg per 667m2 in one cultivation, earlier harvest of 20 - 30 days than normal late rice. It also shows the feasibility of smash - ridging early rice ＋ regenerated rice cropping system for high value - added autumn -winter cropping model.
