一、小麦扬花末期喷硼、磷和腐殖酸钠供试品种是小麦扬麦一号,于五月七日小麦扬花末期,分别用0.2％的硼砂、2％的过磷酸钙和0.25％的腐殖酸钠根外喷雾,喷后每隔一周取样测千粒重,直至收割。试验结果表明,小表扬花末期根外喷磷和腐殖酸钠能增加千粒重。喷磷的,前期灌浆效果不如腐殖酸钠,但对后期灌浆有利,增粒重效果最好,千粒重比对照增加3.23克。喷腐殖酸钠能加速小麦籽粒灌浆,千粒重比对照增
First, wheat at the end of flowering season boron, phosphorus and sodium humate test varieties wheat Yangmai one, on May 7 wheat flowering stage, respectively, with 0.2% borax, 2% of superphosphate and 0.25% Sodium humate spray outside the spray, spray every other week after the sampling of 1000 grain weight, until harvesting. The experimental results show that small praising flowers end-phase phosphorus and sodium humate can increase 1000-grain weight. Phosphating, pre-grouting effect is less than the sodium humate, but the late grouting beneficial, the best grain weight, grain weight increased 3.23 grams more than the control. Sodium humate spray can accelerate the grain filling of wheat, 1000-grain weight increase compared with the control
