【摘要】 通过大田微喷灌节水灌溉方式研究锌腐酸肥料对冬小麦群体、产量及品质的影响。采用磷肥种类为锌腐酸磷酸二铵和普通磷酸二铵;氮肥种类为锌腐酸尿素和普通尿素;不施肥为对照。结果表明:底施普通尿素和磷酸二铵处理的拔节期总茎数和单株茎数均较高;底施普通尿素和磷酸二铵,拔节期追施锌腐酸尿素产量最高,达6 730.5 kg/hm~2。拔节期追施锌腐酸尿素处理的籽粒产量均高于追施普通尿素,增产主要与成穗数和穗粒数增加有关;底施锌腐酸尿素和锌腐酸磷酸二铵,追施锌腐酸尿素的小麦籽粒品质指标最高,拔节期追施锌腐酸尿素的提质效果优于普通尿素。更多还原

【Abstract】 Effects of zinc humic acid fertilizers on community,yield and quality of wheat through water-saving irrigation with micro irrigation were studied. Experimental fertilizers included phosphate fertilizer, nitrogen fertilizer. Phosphate fertilizer species were zinc humic acid diammonium phosphate and ordinary diammonium phosphate,nitrogen fertilizer species were zinc humic acid urea and ordinary urea. The result showed that the total number of stem per hectare and stem number per plant of the treatment with ordinary urea and diammonium phosphate were relatively high. The yield was the highest with ordinary urea and diammonium phosphate used as basal fertilizers and zinc humic acid urea topdressed in jointing stage,which was 6 730. 5 kg/hm2. The yield with zinc humic acid urea applied in jointing stage was higher than that with ordinary urea,which was mainly associated with the increase of number of ears per hectare and grains per ear. Quality indicators were the highest with zinc humic acid diammonium phosphate as basal fertilizer and zinc humic acid urea as both basal and topdressing fertilizer,the effect of zinc humic acid urea applied in jointing stage was better than that of normal urea.更多还原
