堆肥与化肥配施对甘肃河西内陆灌区玉米生长及产量的影响

Effects of combination with compost and chemical fertilizer for maize growth and yield in Gansu inland irrigation area

研究了堆肥与化肥配施对甘肃河西内陆灌区玉米生长及产量的影响。结果表明,堆肥与化肥配施玉米农田中全年光能利用率以处理7(堆肥60 000 kg/hm2+磷二铵210 kg/hm2)最高,为0.884%;玉米水分利用率、经济产量、生物产量和经济总收入均以处理7最高,其中,经济产量水分利用效率为46.85 kg/mm,生物产量水分利用效率为85.72 kg/mm,经济产量为17 280.99 kg/hm2,生物产量为30 886.09 kg/hm2,经济总收入为35 922.5元/hm2。

This study investigated the combination with compost and chemical fertilizer on the growth of inland irrigation of maize and grain yield.Results showed that light energy use efficiency in maize fields was the highest（0.884%）on treatment 7（compost 60 000 kg/hm2＋diammonium phosphate 210 kg/hm2）;Maize water use efficiency,enconomic yield,biological yield and total economic benefit was the highest on treatment 7,economical yield water use efficiency was 46.85 kg/mm,biological yield water use efficiency was 85.72 kg/mm;Economical yield was 17 280.99 kg/hm2,biological yield was 30 886.09 kg/hm2and total economic benefit was 35 922.5 yuan/hm2.
