为合理开发利用冷浆稻田提供科学依据,从1989～1991年设置起垄栽培与普通栽培对比试验,小区面积为500m~2,重复4次。三年的试验结果表明,起垄栽培利于改善冷浆地水、气、热状况,增加土壤通气透水性,总孔隙度和耕层土温。促进土壤速效养分的释放供应,促使水稻根系活力,增加水稻有效分蘖和干物质含量,确保稻谷结实率和安全成熟,其增产率达6.8％～12.3％。可为进一步开发利用延边地区和北方寒冷地区冷浆稻田提供行之有效的方法。
In order to provide a scientific basis for the rational development and utilization of cold paddy rice fields, a contrast experiment of ridge cultivation and ordinary cultivation was set up from 1989 to 1991, with an area of 500m ~ 2 and repeated 4 times. Three years of experimental results show that Ridge cultivation is conducive to improving water, gas and heat conditions of cold slurry, increasing soil aeration and water permeability, total porosity and topsoil temperature. Promote the release and supply of soil available nutrients, promote root activity of rice, increase effective tiller and dry matter content of rice, and ensure rice seed setting rate and safe maturity. Its yield increase rate is 6.8% ~ 12.3%. It can provide an effective method for further exploitation and utilization of cold paddy rice fields in Yanbian area and cold northern areas.
