田林县浪平乡近几年来平均亩产600多斤,从81-85年测产知道,每年都有亩产超千斤,实测亩产高达1298斤。可见,中稻生产潜力还很大,可以进一步提高单产,增加粮食产量。现从气候方面分析浪平乡中稻生产中存在的问题。 一、浪平乡中稻农业气候条件分析 (一)热量资源充足,有利中稻生长 根据水稻对热量条件的要求,日平均气温大于12℃才能开始生长发育,大于21℃才能正常抽穗开花。浪平乡地域目前中稻常用品种需要大于0℃积温和生育期,见表一。
In recent years, Tianlin County, Langping Township, has produced an average of 600 kilos per mu in recent years. From 81 to 85 years of testing, it has been learned that every year, there are over 1000 kilos of mu produce, and the measured output per mu is as high as 1298 kilos. Can be seen that the potential of medium-sized rice production is still great, you can further increase yields, increase food production. Now from the climate analysis of Longping Medium Rice production problems. First, Longping rural agronomy analysis (A) sufficient heat resources, favorable growth of rice According to the requirements of rice on calorie, the average daily temperature is greater than 12 ℃ to start growth and development, more than 21 ℃ to heading and flowering. Waves Township region Currently common varieties of rice need more than 0 ℃ accumulated temperature and growth period, see Table 1.
