摘要
本研究以水稻抛秧技术为龙头，把选用优质品种、塑料软盘种子包衣“五统一”育秧、机械抛秧、一次性全层施肥、提早烤田、化学除草等技术，在单因子试验选优的基础上，组装配套，形成优质、轻型栽培，达到高产、高效的水稻“优轻高”栽培新技术。结果表明，米质可达部颁二级米标准；６６７ｍ２平均产量５０８．２ｋｇ，比湿润秧手插增产１０．６％；用工节省５．５个工日，减少２７．５％，而且免去拔秧、插秧和中耕除草“三弯腰”，劳动强度大大降低；节省生产成本１８．６％；增收节支增长７９．１％。具有显著的经济效益和社会效益。
Based on a single factorial experiment design , this study was conducted mainly for rice seedling throwing cultivation technique integrated with other techniques, such as utilization of excellent cultivars, unified seedling nursry of coated seeds on soft plastic trays in “five aspects” (namely, unified cultivar,unified seed coating, unified sowing time, unified seedling nursery and unified management), mechanical seedling throwing, fertilizer application in a lump to whole plough layer, land drying ahead of schedule and chemical weeding, etc , in order to form a model of excellent and light cultivation to abtain high yield with high efficiency(i e new techniques for“excellent/light/high”rice cultivation) The result showed that the rice measured up to the second class quality of Agricultural Ministry standard; the yield averaged 508 2kg per 666 7m 2, 10 6% higher than that of hand transplanted wet seedlings; 5 5 working days were saved, which decreased by 27 5% less than usual Since bending jobs, such as seedling pulling, rice transplanting, cultivating and weeding, etc , were avoided, labour intensity was enormously lightened The new techniques could save 18 6% of production cost and increase net income by 79 1 % and hence could bring about remarkable economic benifit and social benifit
