在印度西姆拉的酸性丘陵土壤中种植马铃薯,施N肥表现好(Sharma,1986)。Negi等(1982)曾报道过,为有效地利用N肥,平衡施用P、K肥是必要的。Sharma等(1980)发现连年施用农家肥有利于马铃薯生长,因其可部分满足马铃薯对P、K肥的需要。虽然农家肥含有数量可观的N、P、K,但关于它对N肥有效性的影响还知之甚少。因此,本研究进行了温室和田间试验,评价农家肥对马铃薯N肥
Planting of potato in acid hilly soils in Shimla, India, performed well (Sharma, 1986). Negi et al. (1982) reported that it is necessary to balance the use of P and K fertilizer in order to utilize N fertilizer efficiently. Sharma et al. (1980) found that perennial application of peasant fertilizer is beneficial to potato growth because it partially meets the potato’s requirement for P and K fertilizer. Although farmed manure contains a significant amount of N, P, K, little is known about its impact on the effectiveness of N fertilizer. Therefore, this study conducted greenhouse and field experiments to evaluate the effect of peasant fertilizer on potato N fertilizer
