Effect of No tillage and Minimum Tillage Cultivation on Yield and Quality of Rice and Economic Benefit Analysis
In order to explore the effect of different cultivation conditions on yield and quality of rice,taking two different types of rice as materials(Longdao 5which was semi erect panicle variety and Dongnong 428 which was curve panicle variety)that cultivated in the second accumulated temperature region of Heilongjiang province.Contrast test was conducted to analyze the economic benefit of no tillage,minimum tillage and conventional tillage.The results showed that no tillage and minimum tillage cultivation had negative impact on yield and quality,and the effect of no tillage cultivation was greater than minimum tillage.The economic benefit of minimum tillage cultivation was greater than no tillage and conventional tillage.The economic benefit of no tillage cultivation was not great due to its great effect on yield.
