麦田施用不同基肥的肥效试验

MANURE TRILE OF DIFFERENT INITIAL DRESSING IN WINTER WHEAT

对麦田施用不同基肥的效应进行定位试验。结果表明,中产麦田,单施氮磷化肥做基肥,当年增产效果较好。施用有机肥和有机肥加氮磷化肥配合做基肥,即有利于培肥地力,又利于当季增产。秸秆还田加氮磷化肥配合做基肥能明显增加土壤有机质,改善土壤理化性状,但增产效果较差。

Effect of different initial dressing on winter wheat was studied in a located experimental site, The results show that in middle yieldwheat field, initial dressing with nitrogen and phosphorus fertihier conld achieve good rresult in the some year it was applied. There was benifit to soil powerand increase production in the same year it was applied when initial dressing with organure manure or organic manure combined with nitrogen and phosphorus. Applingstraw combined with nitrogen and phosphorus could increase soil organic substance, improve soil physical and chemical characteristiics, but the effect of increase production was lower.
