摘 要:[Objective] The objective of this study was to explore the long-term effect of Fenlong cultivation for one time. [Method] The physical and chemical properties of soil and rice yield and quality were investigated and determined by measuring the soil at the depth of 23 cm in the paddy field with Fenlong cultivation and 16 cm of control (conventional farming) for 7 years. [Result] Compared with the control, the average yield of early rice of the Fenlong cultivation increased by 1 972.5 kg/hm2 of the first year, an increase of 23.87%, and milled rice and protein increased by 15.95% and 14.61%, while the increase rates of organic matter, available nitrogen, available phosphorus and available potassium per hectare were 74.58%, 67.01%, 104.41% and 129.62%, respectively. In the 7th year after Fenlong cultivation, the yield increased by 234 kg/hm2 from the control, an increase of 3.21%, and milled rice and protein increased by 0.5% and 0.14%, while the increase rates of organic matter, available phosphorus and available potassium per hectare were 745.8%, 62.635 and 73.37%, respectively, and the increase rates of total nitrogen, total phosphorus and total potassium were 46.03%, 50.58% and 36.65%, respectively. During the 7 years after Fenlong cultivation, the yield increased by 3.21-23.87%, and its average net income per season increased by 1 843.61 Yuan/hm2 with a gain of 18.03%. [Conclusion] At the 7th year after Fenlong cultivation, the paddy field still had the furrow remain at a depth of 22 cm, which was 46.67% thicker than the traditional one. The yield and quality of paddy rice increased for 7 consecutive vears showed that Fenlon.q cultivation was highly feasible for paddy field.[目的]探索稻田粉垄一次后的多年后效作用。[方法]稻田粉垄23 cm,对照(传统耕作)16 cm,持续7年对其土壤理化性状和水稻产量品质调查与测定。[结果]稻田粉垄当年早稻每公顷比对照增1 972.5 kg、增幅23.87%,稻米品质整精米率和蛋白质分别比对照提高15.95%、14.61%,土壤每公顷有机质、有效氮、有效磷、有效钾含量增幅分别为74.58%、67.01%、104.41%、129.62%;粉垄后第7年早稻每公顷比对照增234 kg、增幅3.21%,稻米品质糙米率和精米率分别比对照提高0.5%、0.14%,土壤每公顷有机质、有效磷、有效钾含量增幅分别为45.8%、62.63%、73.37%,土壤每公顷全氮、全磷、全钾含量增幅分别为46.03%、50.58%、36.65%;粉垄耕作7年间产量增幅为3.21%~23.87%,其平均每季净效益增收1 843.61元/hm^2、增益18.03%。[结论]稻田粉垄第7年耕层仍保留22 cm,比传统增厚46.67%,且水稻当年至第7年增产提质,表明粉垄耕作稻田可行性高。
