摘要
以早熟晚粳新品种武运粳30号为材料,探讨在机插条件下不同密肥管理对该品种产量的影响。结果表明,在行株距为29.7 cm×9.9 cm、每丛5.3株苗规格下武运粳30号产量最高。建议在今后的机插生产中,尽量调小株距、加大抓苗量,达到适宜的群体关系,促早够苗,以获得足够多的有效穗数;在穗肥施用方面,在中期及时搁田、及早落黄的基础上,分2次(倒4叶期和倒2叶期)施穗肥,每667 m^2用量为10 kg尿素或9 kg尿素+9 kg复合肥配合施用。
The effects of different density and fertilizer management on yield of mechanical transplanting rice were studied, with Wuyungeng 30 as material. The results showed that the yield is higher under the condition of plant specifications 29.7 cm×9.9 cm and 5.3 plants/hilh The author put forward some suggestions: turning down the row spacing, increasing grabbing seedlings and using panicles fertilizer at the time of 4th and 2nd to flag-leaf with 10 kg/667 m2 urea or 9 kg/667 m2 urea+9 kg/667 m2 compound fertilizer.
