矿物源腐植酸肥料对冬小麦产量和经济效益的影响

Effects of Mineral Humic Acid Fertilizer on Winter Wheat Yield and Economic Benefit

通过田间试验,研究了施用矿物源腐植酸肥料对冬小麦生长、产量、经济效益的影响。试验结果表明:底肥施用矿物源腐植酸肥料,同时在冬小麦拔节期、孕穗期、灌浆期各喷施1次矿物源腐植酸较单独底肥施用矿物源腐植酸肥料、常规施肥可以明显改善冬小麦的生物学性状,促进灌浆结实,增加穗粒数、千粒重,增产率达15.00%,增产效果显著;产投比达3.30∶1,经济效益明显。

The effects of mineral humic acid fertilizer on the growth,yield and economic benefit of winter wheat were studied through field experiment.The results showed that compared with application of mineral humic acid fertilizer as base fertilizer and conventional fertilization,when mineral humic acid fertilizer was applied as the base fertilizer,mineral humic acid was sprayed once at the pulling stage,booting stage and filling stage of winter wheat,the biological characters of winter wheat were significantly improved.It could promote the grain filling,increase the number of grains per ear,1000-grain weight,and the yield increased by 15.00%.As the ratio of production to investment reach to 3.30∶1,the increase in the economic benefit was obvious.
