【摘要】 为了验证长效多元复合肥在新疆水稻、玉米、冬小麦生产中的施用效果,于2018—2020年进行了大田试验。结果表明:通过基施长效多元复合肥加苗期追施1次氮肥,为水稻、玉米、冬小麦生长提供氮、磷、钾和各种中微量营养元素,解决作物后期早衰和中微量营养元素供应不足等问题。大田对比试验和示范试验结果表明,水稻增产89.7～120.5 kg/667m~2,增产率12.9%～16.5%,增加纯收入248.13元/667m~2;玉米增产153.0 kg/667m~2,增产率15.1%,增加纯收入290.7元/667m~2;小麦增产67.1 kg/667m~2,增产率12.9%,增加纯收入154.3元/667m~2。种植大户无论种植水稻、玉米还是小麦单一作物,应用该项技术每年都可增加纯收入2万元以上。更多还原

【Abstract】 In order to verify the application effects of long-acting multi-element compound fertilizer on rice,corn and winter wheat production in Xinjiang,field experiments were conducted from 2018 to 2020.The results showed that through the base application of long-acting multi-element compound fertilizer and topdressing nitrogen fertilizer once at seedling stage,it provided nitrogen,phosphorus,potassium,and various medium and trace nutrients for the growth of rice,corn and winter wheat;in addition,the problems of premature senescence and insufficient supply of medium and trace nutrients were solved.The results of field contrast tests and demonstration tests showed that rice yield increased by 1 345.5-1 807.5 kg/hm~2 with an increment of 12.9%-16.5%,and the net income increased by 3 721.95 yuan/hm~2;corn yield increased by 2 295 kg/hm~2 with an increment of 15.1%,and the net income increased by 4 360.5 yuan/hm~2;wheat yield increased by 1 006.5 kg/hm~2 with an increment of 12.9%,and the net income increased by 2 314.5yuan/hm~2.The application of this technology can increase the net income by more than 20 000 yuan per year for large growers,regardless of rice,corn or wheat.更多还原
