以2012年常州市水稻苗情哨田块的多点苗情监测数据为样本,分析归纳了种植方式、栽插丛数、播栽期、肥料运筹等因素对机插稻产量形成的影响。结果表明,机插稻较直播稻更高产,减穗增粒特征明显。机插稻获得高产的适宜栽插丛数为1.8万丛/667 m2,适宜移栽秧龄为15~20 d,氮肥运筹中基蘖肥与穗肥适宜比例为6∶4,基蘖肥中基肥与分蘖肥适宜比例为3∶7,分蘖肥最适施用时间为移栽后第2叶龄和第3叶龄。提高抽穗至成熟期干物质积累量是提高机插稻产量的重要途径。

Taking the 2012 multi-point data from rice growth monitoring fields in Changzhou city as sample, the effects of planting pattern, planting density, sowing and transplanting date, application of fertilizer on the machine-transplanted rice were analyzed and summarized. The results showed that machine-transplanted rice yield is higher than direct-seeding rice, the main feature is the ears decreasing but the grain number increasing. The optimum planting density of machine-transplanted rice is 1.8×104 points per 667 m2, the optimum transplanted seedling age is 15~20 days, the optimum proportion between the basal-tiller nitrogen and earing nitrogen is 6∶4, the optimum proportion between the basal nitrogen and tiller nitrogen is 3∶7, the optimunm period of the tiller nitrogen is the sec-ond and third leaf age after transplanted. Increasing the accumulation of biological-yield between heading stage and maturity stage is the key way to increase the yield of machine-transplanted rice.
