| 摘 要： | 为探讨不同耕作条件对两种类型水稻的产量和品质的影响,以黑龙江省第二积温带主栽的两个不同类型的水稻品种(半直立穗型品种龙稻5号和弯曲穗型品种东农428)为试验材料,进行不同耕作方式(免耕、少耕、翻耕)的对比试验,最终进行了3种不同耕作方式的效益分析。结果表明:稻田免耕、少耕栽培方式对水稻产量和品质均产生负影响,且免耕明显大于少耕;少耕栽培方式经济效益明显高于翻耕、免耕栽培方式,由于免耕栽培方式对产量影响过大,经济效益并不是最高。

| Abstract: | In order to explore the effect of different cultivation conditions on yield and quality of rice, taking two different types of rice as materials（l.ongdao 5 which was semi erect panicle variety and Dongnong 428 which was curve panicle variety）that cultivated in the second accumulated temperature region of Heilongjiang prov ince. Contrast test was conducted to analyze the economic benefit of no-tillage,minimum tillage and convention al 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 mini- mum 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. |
