摘要: 【目的】探索农耕新方法粉垄栽培水稻的可行性及其对水稻产量和品质的影响。【方法】以Y两优1号, 汕小占为供试材料,传统翻耕浆耙栽培为对照(CK),进行早稻粉垄栽培和晚稻免耕抛秧栽培试验,对相关性状和产量、品质进行调查和测定;并对粉垄后第三造轻耕种植水稻的产量及土壤的紧实度进行调查。【结果】粉垄栽培与CK相比,早造粉垄稻田耕层厚度加深7 cm,土壤速效养分多数指标增加10%以上,水稻总根数量及白根数量分别增加14.83%—25.36%、20.18%—97.78%,稻株生物产量增加29.96%—31.89%,结实率增加7.62%,稻谷产量增加23.87%,整精米率、蛋白质分别增加15.95%、14.61%;晚造免耕抛秧比CK的总根数量和白根数量分别增加6.02%—22.75%、48.03%—65.91%,产量增加9.25%,整精米率、蛋白质分别增加7.43%、5.61%;早晚两造合计增产16.48%,增加收入6 706.5元/hm2;粉垄后第三造轻耕种植水稻收获时耕作层土壤的紧实度比对照降低68.00%—333.33%,产量增加7.97%。【结论】粉垄栽培水稻,当造和后一造免耕均可行,均能提高稻谷产量和改善稻米品质,增加纯收益;粉垄后第三造仍能提高稻谷产量,粉垄后稻田具有持续增产能力。

Abstract: 【Objective】The feasibility of the new farming method of Fenlong cultivation for rice, and its effects on yield and quality of rice were studied.【Method】YLiangyou1 and Shanxiaozhan were used as materials in the test, the traditional ploughing with rake was used as CK, and smash-ridging cultivated early rice and no-tillage of late rice were carried out to investigate the related characters, yield and quality of rice. The yield of the third time planted rice after Fenlong and soil compactness were investigated.【Result】Compared with the traditional cultivation, Fenlong planted early rice increased the plough layer by 7 cm, most indicators of soil available nutrients increased by more than 10%, total number of root and white roots increased by 14.83%-25.36% and 20.18%-97.78%, respectively, the plant biological yield increased by 29.96%-31.89%, seed setting rate increased by 7.62%, yield increased by 23.87%, the whole head rice rate and protein increased by 15.95% and 14.61%, respectively; In no-tillage and seedling-throwing late rice, compared with CK, Fenlong total number of root and white roots increased by 6.02%-22.75% and 48.03%-65.91%, and yield increased by 9.25%, the whole head rice rate and protein increased by 7.43% and 5.61%. The early and late rice total yield increased by 16.48%, income increased by 6 706.5 Yuan/hm2. Compared with the CK, the third time planted rice after Fenlong farming, soil compactness reduced by 68.00%-333.33%, and yield increased by 7.97%. 【Conclusion】Fenlong cultivation of early rice and no-tillage late rice are feasible and it can increase rice production, improve rice quality, and increase  net income. Fenlong still can increase the yield of the third time planted rice, the rice paddy field possess the sustainable yield increasing ability after Fenlong farming.
