活性腐殖酸有机肥对水稻产量·养分吸收的影响

目的]研究活性腐殖酸有机肥对水稻产量、生长状况和养分吸收的影响。方法]以水稻为研究对象,采用水稻盆栽试验,分别设置活性腐殖酸有机肥和化肥的不同用量处理。结果]施用活性腐殖酸有机肥比等养分量化肥明显提高水稻经济系数;施用活性腐殖酸有机肥主要通过增加水稻的穗粒数来提高经济产量;活性腐殖酸有机肥明显提高水稻磷吸收量,化肥处理明显提高钾吸收量,而都对氮吸收无明显影响。结果]在腐殖酸肥料处理中,水稻的株高、总分蘖数、有效分蘖、生物产量等指标随着肥量的增大都呈现先增加后降低的趋势,处理⑥均达到最大值。在施用化肥的处理中,水稻各指标的变化趋势同腐殖酸肥料处理,但处理⑨的有效分蘖和生物产量为最大值。结论]施用活性腐殖酸有机肥可以提高氮肥利用率,提高水稻产量。

Effect of Humic Acid Fertilizer on Rice Yield and Nutrient Uptake

Objective] The research aimed to study the effect on rice yield,the growth status and nutrient uptake using activity humic acid fertilizer.Method] Rice was studied as the research object by rice potted trial.Humic acid fertilizer and chemicalfertilizers were set up to treatments with different dosages.Result] The humic acid fertilizer increased economy coefficient of rice significantly.Applying Humic acid fertilizer mainly improved economic output by increasing the TNSP of rice.Using humic acid fertilize...
