| 摘 要： | 研究寒地稻草还田对寒地水稻生长发育、产量和品质的影响。结果表明,不同还田量处理的水稻株高、地上部植株干重、叶绿素含量和叶面积指数在生育转换期较对照低,长穗期和结实期与对照无明显差异;不同还田量处理在每穗粒数和结实率上与对照相比均达到显著水平,产量、穗数和千粒重均未达到显著水平;秸秆还田处理的稻米出糙率和精米率高于对照,垩白率和垩白度低于对照。还田9t/hm2处理提高了蛋白质含量,同时也提高了直链淀粉含量,但降低了食味品质。

| Abstract: | The effects of straw return plus nitrogen fertilizer on growth and development,yield and quality in rice were studied.In comparison with the rice-straw removal treatment,the rice-straw return treatment reduced the plant height,dry matter weight,chlorophyll content and leaf area index during growth transition period,whereas no significant differences between both the treatments were observed during the heading period and the grain-filling period.There were no significant differences in yield components (grai... |
