摘要:

节水与高值化是稻田生态种养模式的未来发展方向之一。采用农户种养和田间调查的方法,研究了水稻垄栽种养新模式的水稻产量、经济效益以及水分的运动过程。结果表明:与水稻单一种植(CK)相比,稻野鸭种养模式(RM)和稻鳖种养模式(RT)的水稻产量增加了9.4%和18.0%,RM和RT的利润、产投比、劳动生产率、成本收益率比CK分别增长了4.2和14.4倍、32.6%和8.9%、3.4和4.3倍、245.0%和24.6%,确保粮食增产和农民增收;水稻垄栽种养模式改变了水分运动路径,经蒸腾作用的水分损失量比水稻常规种植模式高16%,间接说明水稻垄栽种养模式可提高水的利用效率。

Abstract: Water saving and high-value is one of development directions of the ecological planting and breeding model in the future. In this paper, rice yield, economic benefits and the process of water movement in the planting and breeding model under rice ridge cultivation were studied with the method of farmers’ planting and breeding and field survey. The result showed that, compared with rice mono-planting model (CK), the rice yield of rice-mallard complex ecosystem under rice ridge cultivation (RM), rice-turtle complex ecosystem under rice ridge cultivation (RT) increased by 9.4% and 18.0%, respectively, and net income, output/input ratio, labor productivity, cost-benefits ratio in the RM and RT increased by 4.2 and 14.4 times, 32.6% and 8.9%, 3.4 and 4.3 times, 245.0% and 24.6%, respectively, which ensured increasing food production and farmer’s income. The planting and breeding model under rice ridge cultivation changed the pathway of water movement. The quantity of water loss via transpiration in the planting and breeding model under rice ridge cultivation was 16% higher than CK. Our results suggest that the planting and breeding model under rice ridge cultivation can increase water use efficiency.
