摘要
为了探索改善土壤环境、促进花生生长发育、提高产量的合理施肥方式,以施用干鸡粪15 000kg/hm^2所含营养元素为基准,开展相同氮磷钾含量、不同有机质梯度随机对比试验。结果表明:各施肥方式处理可改变土壤酶活性状况,提高荚果与植株的养分累积吸收量,可将氮、磷、钾肥利用率从T2(纯化肥处理)的26.3%、11.3%、31.7%提高到T5(化肥配施干鸡粪11 250 kg/hm^2)的73.8%、20.0%、64.1%,后者花生荚果单产最高,为7 338.0 kg/hm^2,较T2增产27.60%,为本研究最佳施肥方式,即在施干鸡粪11 250 kg/hm^2基础上施尿素84 kg/hm^2、磷酸二铵124.5 kg/hm^2和硫酸钾64.5 kg/hm^2。
In order to explore the rational fertilization mode to improve soil environment,promote peanut growth and development and increase yield,based on the basic standard of fertilization as the N,P and K contents of 15 000 kg/hm^2 dried poultry litter,the contrast tests were conducted under six treatments of different combinations of N,P and K fertilizers and organic matter fertilizer.The results showed that the soil enzyme activities could be improved and the nutrient accumulation and absorption amounts of pods and plants were increased under fertilization treatments.The utilization rates of N,P and K fertilizers of T2 treatment were26.3%,11.3% and 31.7%,while those were raised to 73.8%,20.0% and 64.1% under T5 treatment,respectively.The pod yield of T5 treatment was the highest as 7 338.0 kg/hm^2,which was 27.60% higher than that of T2 treatment.Therefore,T5 treatment was the best fertilization mode,which was combined with11 250 kg/hm^2 dried poultry litter,84 kg/hm^2 urea,124.5 kg/hm^2 diammonium phosphate and 64.5 kg/hm^2 potassium sulphate.
