提高宜优673中高海拔区域制种产量关键技术

摘要

Yiyou 673 is a high yield and quality variety matched by the rice research institute of Fujian Academy of Agricultural Sciences.Its hybrid seed yield is low in the middle-high altitude areas.After many years of observation and investigation,we found the factors initially,and summarized the corresponding technical measures for high-yield cultivation.%宜优673是福建省农业科学院水稻研究所配组的高产优质品种,但该品种在中、高海拔地区制种产量低。经过多年的观察调查,初步找到该品种在中海拔区域制种低产的成因,并总结出相应的高产栽培技术措施。
