地膜玉米控释肥肥效试验研究

Experimental Study of Efficiency of Controlled Release Fertilizer for Film Mulching Maize in Year 2011

对全膜双垄沟播和半膜平铺穴播条件下6种不同控释肥肥料组合控释肥试验,结果表明,控释肥基施651 kg/hm2、拔节期追施349 kg/hm2组合方式增产效果最好,在全膜双垄沟播条件下玉米产量达到8 088 kg/hm2,在半膜平铺穴播条件下产量达到7 675 kg/hm2,分别较对照增产26.10%和38.61%。

An experiment was conducted with 6 treatments of different fertilizer combinations under the conditions of film whole-mulching double furrow sowing and film half-mulching hole sowing. The results showed that the combination of the base application of controlled release fertilizer 651 kg/hm^2 and topdressing of controlled release fertilizer 349 kg/hm^2 at jointing stage had a best effect in yield increasing. The maize yields reached 7 675 kg/hm^2 under the condition of film whole-mulching double furrow sowing and 8 088 kg/hm^2 under the condition of film half-mulching hole sowing, increasing by 26.1% and 38.61% respectively.
