摘要
对农业废弃物无害化处理后,添加一定的无机肥后制作成有机无机复混肥,使其肥料化资源利用.为了进一步研究有机无机复混肥的肥效,2001～2003年在夏玉米上进行了连续3年田间试验,试验结果表明,有机无机复混肥可以促进玉米生长,增加玉米生物产量1958.0～2770.5kg·hm-2,改善玉米产量结构,提高玉米籽粒产量866.0～1144.5kg·hm-2.并能降低玉米耗水系数,提高玉米水分利用效率2.680～3.399kg/ mm·hm2 .在旱地施用有机无机复混肥,可以提高旱地水资源的利用效率.
After the agricultural waste has been decomposed to be harmless to environment,the organic-inorganic fertilizer was made from it by added up a certain inorganic fertilizer in order to utilize it as resource of manure.In order to study the effect of the organic-inorganic fertilizer on crops,the field experiment of applying the organic-inorganic fertilizer in summer maize was carried out from 2001 to 2003.The result showed that the organic-inorganic fertilizer could improve the growth of maize,increase the yield of dry plant of summer maize 1 958.0~2 770.5 kg·hm^(-2),make better the composition of yield of summer maize,increase the yield of summer maize 866.0~1 144.5 kg·hm^(-2) and raise the water use efficiency of summer maize 2.680~3.399 kg/(mm·hm^(2)).The water use efficiency can be improved by applying the organic-inorgainc fertilizer to crops in dry land.
