摘要
通过对本地区早、中、晚熟代表品种进行乳苗早栽试验,并与五月下旬移栽中苗相比,乳苗表现出较强的优势。乳苗早栽秧苗素质的各项指标,均比对照中苗提高;产量高于对照,并且按照熟期不同,增产幅度由早熟品种向晚熟品种递减。
Experiment of early transplanting nursing-seedling was carried out, using early maturing, middle maturing and late maturing varieties in this region as experimental material. Compared with middle-seedling transplanting in late May, nursing-seedling had stronger superiority. Every index of seedling quality of early transplanting nursing-seedling was higher than those of middle-seedling, so yield did it. According to different mature stages, the range of yield increased taking on the trend of decline from early-mature to late-mature varieties.
