信阳地区处于江淮流域,自然条件优越,气候具有南北稻区昼夜温差大和雨量较多的特点,很适合水稻种植,属一年一季和稻麦两熟区.全区常年种稻约500万亩,占总耕地面积60%左右,而稻谷产量占粮食总产80%左右.根据本区水稻生产中存在的问题,提出几点意见:一、品种严格提纯复壮,合理搭配.多年来各地自行引种,缺乏严格去杂提纯措施,造成品种多、乱、杂局面,大大地影响了产量.一般纯种能增产10%,所以对当家品种如南京11号、84矮63、珍珠矮11号、广选3号等,必须认真进行穗选和块选(有条件的可建立三圃制),并选用生育期125-130天、130-135天、135-140天的不同熟期的品种搭配种植,以便错开农活,达
Xinyang area is in the Yangtze River and Huaihe River Basin, natural conditions are superior, the climate has a large temperature difference between day and night in the northern and southern rice and rainfall characteristics, it is suitable for rice cultivation, is a year and rice and wheat two ripening area.The perennial species of about 5000000 acres of rice, Accounting for about 60% of the total cultivated land, while the output of paddy accounts for about 80% of the total grain output.According to the existing problems in rice production in this area, a few suggestions: First, the species strictly purified and rejuvenated, with reasonable. The lack of strict measures to remove impurities, resulting in more variety, chaos, miscellaneous situation, greatly affected the yield.General purebred can increase 10%, so the varieties such as Nanjing 11, 84 short 63, pearl short 11, No. 3, etc., must ear carefully selected and block selection (conditions can be established San Pu system), and select the growth period of 125-130 days, 130-135 days, 135-140 days of different maturity varieties with planting, In order to stagger the farm, up
