摘要
通过盆栽试验,比较研究了生物有机复混肥(BCF)、包硫缓释肥料及无机复合肥的效应.结果表明,BCF能显著增加土壤中微生物数量,提高土壤有效磷和有机质含量,促进植株生长发育,提高产量.同等施肥量下,BCF的处理在植株生长过程中固氮菌、有机磷细菌、钾细菌分别是无机复合肥处理的3.1～7.6倍、3.6～6.4倍和2.4～9.2倍;产量较无机复合肥的处理增加了5.8%,有机质增加了14.6%.
A pot experiment was carried out to compare efficiencies of an inorganic compound fertilizer, a sulfur coated slow release fertilizer and a new biological-organic compound fertilizer （BCF）. The results showed that the application of BCF increased the soil microorganisms greatly, raised the available P and organic matter contents, promoted plant growth and development, and increased plant yield. With the same fertilizer amount, the number of N-fixing bacteria, P-releasing bacteria, K-releasing bacteria of BCF treatment increased by 3.1 ～ 7.6 times. 3.6 ～6.4 times and 2.4 ～9.2 times respectively when compared with the inorganic compound fertilizer treatment; while the yield of BCF treatment increased by 5.8% and organic matter content increased by 14. 6%.
