摘要

以粉煤灰为主要包膜材料

同时添加硝化抑制剂双氰胺(DCD)

对普通复合肥进行包膜

制备了DCD含量分别为0%

2%和4%的4种包膜缓释复合肥

并进行土壤培养试验和田间试验

研究包膜缓释肥的氮素释放特征及其对大白菜生长的影响。结果表明:(1)硝化抑制剂与粉煤灰包膜结合能有效地保持氮素养分较长时间处于NH4+-N形态

减少了因转化为NO3--N形态而造成的养分淋溶损失。4种自制包膜肥的缓释效果为:4%DCD>2%DCD>1%DCD>0%DCD。(2)在施肥水平相同的情况下

与普通复合肥相比

4种自制包膜复合肥均能提高大白菜中后期叶绿素含量、净光合速率(Pn)、蒸腾速率(E)

但与树脂包膜肥相比差异不显著

表现为:1%DCD≈2%DCD>0%DCD>4%DCD。与普通复合肥相比

除DCD含量为4%的包膜肥减产减收外

其他3种自制包膜肥使生物产量提高14.0%～17.2%

经济效益提高14.5%～17.5%

与树脂包膜肥相比差异不显著;所有包膜复合肥与普通复合肥相比

能提高含糖量、糖酸比及维生素C含量和降低硝酸盐及有机酸含量

且与施用树脂膜复合肥的效果相当。

Abstract

Four homemade compound fertilizers with nitrification inhibitor dicyandiamide(DCD) being ratio 0%

2% and 4%

separately were prepared out of common compound fertilizer by coating them with fly ash as major material.Soil incubation experiment and field experiment were used to study N-release characteristics of the fertilizers and their effects on Chinese cabbage.Results showed that:(1)Using four kinds of fertilizers could keep N as NH+4-N for a long time

consequently

reduce the risk of nitrate N losses.The...
