豫粳 6号品种具有叶短、直立、色淡 ,分蘖力极强 ,植株紧凑 ,茎基粗壮 ,节间短 ,穗大粒多 ,熟相佳 ,灌浆速度快等突出优点。每 6 6 6 7m2 6 5 0kg以上水平的产量结构应为 :有效穗数 2 3万左右 ,每穗总粒数 130粒左右 ,结实率 95 %左右 ,千粒重 2 6 5g以上。主要技术措施有 :旱育长龄健根多蘖壮秧 ;扩行缩墩减苗 ;适时适度搁田 ;均衡施氮 ,前后期施氮比例为 6∶4,增施促花复合肥。氮、磷、钾配比以 1∶0 5∶0 6为宜
Yujing 6 varieties with short leaves, upright, pale, strong tillering ability, compact plants, stalks stout, short internodes, spike large grain, cooked phase is good, fast filling and other prominent advantages. Each 6 6 7m2 6 5 0kg above the level of output structure should be: effective spike number about 230,000, the total number of grains per panicle is about 130, about 95% seed set, 1000 grain weight more than 265g. The main technical measures are: drought-tolerant long-Jian Kenneth multi-tiller sturgeon seedlings; extension expansion pier shrinking seedlings; appropriate moderate Tian; balanced nitrogen application, the proportion of nitrogen application before and after 6: 4, increase the flowering compound fertilizer. Nitrogen, phosphorus and potassium ratio of 1:05:06 is appropriate
