摘要
Abstract
In order to determine the reasonable amount of potato specific fertilizer,the sweet potato variety Xiguahong was used as the experimental material,and four treatments(0 kg/hm2,225 kg/hm2,450 kg/hm2,675 kg/hm2)were set up to study the effects of different amounts of potato specific fertilizer on sweet potato yield and soil nutrients.The results showed that the treatment with 450 kg/hm2 of potato specific fertilizer had the highest yield(44 715 kg/hm2);the regression analysis results showed that when the amount of potato specific fertilizer was 435.19 kg/hm2,the sweet potato yield was the highest;with the increase of potato specific fertilizer,there was a increasing trend of alkali hydrolyzed nitrogen,available phosphorus,available potassium,and EC value,while pH value decreased.In the actual production process,it is necessary to apply potato specific fertilizers reasonably based on the soil basic fertility.关键词
