根据三年水稻晚栽高产技术研究的结果,认为营养士旱育,长龄带蘖的壮秧是晚栽高产的关键。中熟品种稀播晚栽产量高于早熟品种晚播晚栽。晚栽品种以沈农1033较安全,在辽宁省南部可用辽粳5号。本文还阐明了晚栽水稻的生育特性,经济性状及产量变化规律,并提出了晚栽高产的其他技术措施.
According to the results of three years of late rice high-yielding cultivation techniques, it is considered that the nurse of nurses in the nursery and the long-aged and tillering seedlings are the key to high yield of late-cropping. Medium maturing varieties of late sowing late sowing more than late varieties of early maturing late sowing. Late planting varieties Shennong 1033 safer, available in southern Liaoning Liaodi 5. The article also clarified the characteristics of late growth of rice fertility, economic traits and yield changes, and put forward late planting high yield of other technical measures.
