摘要
在水稻上进行PGPR促生菌肥效果试验,试验结果表明该生物肥料对水稻生长发育和产量的影响明显高于对照和单施N、P、K化肥,改善了水稻经济性状。使株高、穗长、单位面积穗数显著优于对照,有效分蘖比单纯施用化肥平均增加20个/m2,结实率提高1.8%,处理区施用PGPR促生菌肥比单施化学肥料和不施肥对照分别增产26.0%和53.9%。
The experiments were conducted to study the effects of PGPR bio-fertilizer on rice. The results indicated that the application of the bio-fertilizer was better than that of N、P、K chemical fertilizer only. The effect could not only improve rice economic properties, increase height of rice, and length of ears, but also improve the bearing fruit rate of 1.8%, increase yield 26.0% and 53.9% more than N、P、K chemical fertilizer only and contrast.
