今年我省早、中稻杂种示范栽培800多亩。统计28个点,480多亩,平均亩产1031.5斤,其中亩产1200斤以上的88.62亩,1300斤以上的16.24亩,有小面积高达1700—1800斤,形势喜人。通过一年实践,我们对杂种的根系发达、耐肥抗倒、分蘖力强、成穗率高、不早衰、穗大粒多、空壳少等优势,有了进一步的认识。根据这些特性,采取相应的栽培技术,可以获得大面积每亩一季千斤以上的产量。 This year in our province, early rice hybrid demonstration cultivation of 800 mu. Statistics 28 points, 480 mu, the average yield of 1031.5 kg, of which 88.62 mu per mu yield of more than 1200 pounds, more than 1300 pounds of 16.24 acres, a small area of ​​up to 1700-1800 pounds, the situation is gratifying. Through one-year practice, we have further understanding of the hybrid root system developed, resistance to fattening down, strong tillering ability, high ear rate, early premature aging, spike large grain, less shell and other advantages. According to these characteristics, take the appropriate cultivation techniques, you can get a large area per acre more than one kilogram of output.
