利用杂交优势来提高水稻产量,是一个值得研究的问题。今年我场试种了六个组合的杂种,计26亩,亩产都在1000斤左右,其中2.6亩,亩产达1185斤。一年的实践证明,水稻杂种具有很大的增产潜力,其杂种优势表现如下: 一、秧苗长势好,分蘖早,抗性强。杂种在秧苗期间长势旺盛,落谷后十天左右开始分蘖,比一般品种分蘖早而多,根系发达,茎秆粗壮,抗寒力也比当家品种强,
Using the advantages of hybridization to increase rice yield is a problem worth studying. This year, I experimented with six hybrids in the field, measuring 26 acres with a yield of about 1,000 pounds per mu, of which 2.6 acres and an average yield of 1185 pounds per mu. One year of practice has proved that rice hybrids have great potential for yield increase and their heterosis shows as follows: First, the seedlings grow well, early tillering and strong resistance. Hybrids grow vigorously during the seedling period, starting tillers about ten days after the fall, early and more than the average varieties of tillering, developed roots, stem sturdy, cold hardiness than the varieties,
