摘要
试验设置有机肥(667m2用清粪水1000～2000kg)作高粱移栽底肥,在高粱拔节期和孕穗期限量追肥(667m2用尿素8～32kg)。结果表明:不施化肥,只施有机肥1000kg/667m2的高粱产量最低(285.51kg/667m2);施有机肥2000kg/667m2、拔节期和孕穗期分别追施尿素8kg/667m2的高粱产量最高(435.24kg/667m2);施有机肥1500～2000kg/667m2、追尿素12～20kg的高粱产量达398.58～435.24kg。经品质、农药残留、重金属等项目分析,符合高粱卫生安全指标要求,说明施肥对高粱籽粒品质没有影响。
Three organic fertilizer amounts （as the base manure） and four urea amounts （as the top dressing） were tested to investigate effects of different application amount of organic and urea fertilizers on yield and quality of sorghum. The results show that the yield of applying 1000 kg/667m^2 of organic fertilizer is the lowest （285.51 kg/667m^2） and the yield of applying 2000 kg/667m^2 of organic fertilizer, 8 kg/667m^2 of urea at the jointing and booting stage respectively is the highest （435.24 kg/667m^2） in the all tested treatments. The yield can reach to 398.58～435. 24 kg/667m^2 when 1500～2000 kg/667m^2 of organic fertilizer （as the base manure） and 12～20 kg/667m^2 of urea （as the top dressing） are applied. The analysis index of quality, pesticide residue and heavy metals is in accord with the standard of sorghum healthy and safety, which expresses that the tested fertilizers has no effects on sorghum quality.
