摘要
1992到 1997年 ,在 2 9个村镇 4 5个试验点进行了花生施用生物磷肥的对比试验。试验结果表明 ,花生施用生物磷肥后 ,出苗早 ,苗壮 ,成熟期提前 ,荚果饱满 ,花生产量显著提高 ,平均增产 568.5kg/hm2 ,增产幅度为 7.0 %～ 4 9.3% ,平均增产 15.6%。
The control experiments with application of biological phosphorus fertilizer to peanut were made in 45 selected units in Hebei Province from 1992 to 1997. The results showed that when biological phosphorus fertilizer was applied, peanut germinated early and grew well, maturing period moved up, maturity was fine and yield of peanut increased remarkably. The average yield increased by 15.6% (568.5 kg/hm 2) and the rate range of the increased yields was 7.0%～49.3%.
