不同基肥用量对青饲玉米产量的影响

对青饲玉米施用不同的肥料品种和用量作基肥,对产量有明显的影响：有机肥作基肥,肥效期长,但玉米吸收慢,满足不了玉米快速生长的需求;纯化肥N、P、K搭配作基肥,玉米生长快,产量高,但到后期有脱肥现象;以化肥N、P、K搭配一定量的农家肥作基肥最好。

Effects of Different Planting Density and Fertilizer Ratio on Maize Yield

This study of green corn type and content of applying different fertilizers as basal, the results showed that had obvious effect on production： organic fertilizer as basal, exploiting the period was long, but corn absorb slowly, meet the needs of the alerts of maize growth; Pure as basal fertilizer N, P, K collocation, maize growth was fast, high output, but late to have to take off the fat phenomenon; To match a certain amount of fertilizer N, P, K farmyard manure as basal best.
