通过湘北平湖区机械直播早稻创丰1号高产配套技术研究,结果表明:(1)适宜播量75kg/hm2;(2)适宜播期4月4日左右;(3)适宜大田施氮量172.5~187.5kg/hm2;(4)播后20d用5%稻杰悬浮剂600~900ml/hm2加10%千斤乳油600ml/hm2防除稻田杂草达90%以上,控制了草害;(5)示范片群体结构合理,结实率较高,产量高,平均产量7.10t/hm2,高产丘块7.71t/hm2。基本上解决了人工撒播出苗、除草、倒伏难题,有利于实现水稻生产全程机械化生产。
The results showed that: (1) Suitable sowing rate was 75kg / hm2; (2) Suitable sowing dates were on April 4; (3) Nitrogen application rate in field was 172.5 ~ 187.5kg / hm2; (4) After 20 days of sowing, weed control over grass weeds with 600% ~ 900ml / hm2 of 5% Daojie suspension and 600ml / hm2 of 10% The population structure is reasonable, high seed setting rate, high yield, the average yield of 7.10t / hm2, high yield mound 7.71t / hm2. Basically solved the problem of artificial sprouting, weeding and lodging, is conducive to the realization of full mechanized production of rice production.
