V48—2(V20 A X测48—2),是湖南杂交水稻研究中心培育成功的一个早熟杂交稻新组合。1988年我县引进该组合在望城、石埠、乐化、松湖等乡作早稻试种,面积共413亩。3月底4月初播种,4月底5月初插秧,7月15日左右成熟,全生育期只有106天。在今年7月份酷热无雨的特殊气候条件下,由于高温逼熟,使早稻生育期缩短空秕粒增多,V48—2也比正常年景早熟4～5天,但仍然获得平均亩产917斤,最高的达1035斤的好收成,比常规稻亩增150～250斤,增产21.4～35.7％。按每百斤稻谷21.50元计,亩增值32.25～53.75元,亩增纯收入29.25～47.75元。群众认为是目前杂交早稻中一个早熟高产的好组合,明年可以推广。
V48-2 (V20 A X 48-2), is a new breed of early-maturity hybrid rice cultivated successfully in Hunan Hybrid Rice Research Center. In 1988, our county introduced the combination of early rice cultivation in the towns of Hope City, Shibu, Yuehua and Songhu, covering an area of 413 mu. The end of March early April sowing, early April early May planting, July 15 or so mature, the whole growth period of only 106 days. In July this year, under extremely hot and rainless special climatic conditions, due to high temperature ripening, early rice growth period to shorten the increase in empty grains, V48-2 than the normal years of premature 4-5 days, but still get an average yield of 917 pounds , The highest up to 1035 pounds of good harvest, than the conventional rice acres by 150 to 250 pounds, an increase of 21.4 ~ 35.7%. Calculated at 21.50 yuan per kilogram of rice, the added value of mu is 32.25-53.75 yuan, and the net income of mu is increased by 29.25-47.7 yuan. The masses think it is a good combination of early maturity and high yield in hybrid early rice and can be popularized next year.
