| 摘 要： | 三熟制油菜简化施肥的试验结果表明,简化施肥对油菜株高、茎粗、有效分枝数、第一节位高、主花序长和主花序角果数都有一定影响,而对油菜每荚粒数没有影响,对单株角果数、千粒重、成熟期干物质积累和理论产量的影响较大,产量从高至低依次为简化施肥Ⅲ、简化施肥Ⅱ、常规施肥(CK)、简化施肥Ⅰ。简化施肥对油菜生育进程影响很小,前期几乎没有影响,到了生育后期差异1~3 d;简化施肥比常规施肥减少生产投入294.0~450.0元/hm2,增收181.8~1100.7元/hm2,以简化施肥Ⅲ的经济效益最高。

| Abstract: | Tests of simplified fertilization for the triple cropping rapeseed were carried out in red soil paddy field of Jiangxi.The results indicated that simplified fertilization had a certain influence on rape plant height,stem diameter,effective branches,the first section height,length of rachis and number of pods per rachis,while had no influence on the number of seeds per pod.Simplified fertilization had a greater effect on the number of pods per plant,1000-seed weight,dry matter accumulation at the mature stag... |
