海城市验军乡二道村1987年共种70亩早稻,在连续40天干旱的不利气候条件下,获得了平均亩产549.4公斤的好收成。科技示范户孙日胜的3亩水稻旱种平均亩产582.3公斤;戴洪库的3亩达569.2公斤。据计算,旱稻亩产500公斤的纯效益比亩产600公斤玉米增加70元左右,因而受到农民的欢迎。二道村农民的经验是,要想使水稻旱种高产,必须把好“三关”。提高播种质量保全苗旱种稻应选择早熟、幼苗顶土力强、抗旱、抗倒、耐肥的高产品种。经几年的试种,他们认为秋光品种较为合适。因此,今年的水稻
Erdao Village, Haijun City Military Examination Township A total of 70 mu of early rice was planted in 1987, obtaining a good yield of 549.4 kilograms per mu under the adverse climatic conditions of 40 consecutive days of drought. Science and technology demonstration households Sun Risheng 3 acres of dry cultivation of rice average yield of 582.3 kilograms; wearing Hong library of 3 acres of 569.2 kilograms. It is calculated that the net benefit per 500 kilos of dry land per mu is about 70 yuan higher than that of 600 kilograms per mu, which is why farmers are welcome. The experience of Erdao village peasants is that in order to make dry cultivation of rice high yield, we must make a good “three levels off.” Improve the quality of planting seedlings of dry and upright rice should be selected precocious, strong top soil seedlings, drought-resistant, anti-down, high-yield resistant varieties. After several years of trial planting, they believe that autumn light varieties are more appropriate. Therefore, this year’s rice
