冷烂锈稻田通过工程改良、垄作栽培、湿润栽培,分别比对照(未改良)提高泥温3.12℃、3.30℃、2.62℃,水温3.38℃、3.51℃、1.95℃。每亩净增产分别为218斤、303斤、181斤。四种处理产量差异达到极显著水平。从经济效益来看,工程改良每亩净增收10.07元,并且以后不再投资(为一次性投资,以后多年均产生效益);垄作栽培净增收29.95元;湿润栽培净增收18.82元。通过一年的试验初步表明:以上几种改良冷烂锈稻田的方法都是有效的,在生产上是有实际意义的。
Cold paddy rice paddy through engineering improvements, ridge cultivation, wet cultivation, respectively, than the control (unmodified) to increase the mud temperature 3.12 ℃, 3.30 ℃, 2.62 ℃, water temperature 3.38 ℃, 3.51 ℃, 1.95 ℃. Net yield per acre were 218 pounds, 303 pounds, 181 pounds. The difference between the four treatments reached a very significant level. From the economic point of view, the project improved net income per acre 10.07 yuan, and no longer invest (for a one-time investment, after many years have produced benefits); ridge cultivation net income 29.95 yuan; wet cultivation net income 18.82 yuan. Through a year of preliminary tests showed that: The above methods to improve the cold rotten rust paddy fields are valid, in the production of practical significance.
