2005年在宁远县大枧头村进行了稻草覆盖还田晚稻免耕节水栽培技术试验示范,结果表明,晚稻采用稻草覆盖还田免耕节水栽培技术可以降低田间水温和泥温,有利于插后返青分蘖,能有效改善水稻的经济性状,从而明显提高晚稻的产量。同时可以减少灌水次数,节约大量灌溉用水,具有较好的经济、社会和生态效益。
In 2005, Daitou Toucun, Ningyuan County, carried out demonstration experiments on no-tillage and water-saving cultivation techniques of late rice covering straw and returning rice. The results showed that water-saving cultivation technique of late-rice without straw can reduce field water temperature and mud temperature, Plug tiller back green, can effectively improve the economic traits of rice, thereby significantly increasing the yield of late rice. At the same time, it can reduce the frequency of irrigation and save a lot of irrigation water, which has good economic, social and ecological benefits.
