近年来，滴灌节水农业技术及其与灌溉设施相配套的水肥一体化技术在乌兰察布马铃薯生产中的应用越来越广泛。但实际生产中，种植者常因将杂质含量大、难溶解的常规肥料应用于滴灌系统，而造成滴头堵塞。液体肥料具有溶解性好、杂质少等优点，是利用滴灌设施进行追肥的理想肥料。在田间试验条件下，研究了在适量降低基肥用量的同时，通过每667m2滴灌追施10、20、30kg农季高液体肥对马铃薯生长、产量及商品性状的影响。结果表明，追施农季高液体肥处理比传统追肥处理增产显著，马铃薯块茎产量增幅达13．52％-22．36％，商品率提高4．68％-6．55％，每667m2增收401．85-527．95元，经济效益显著提高。表明农季高液体肥可以在马铃薯作物上推广应用。

In recent years, Wulanchabu is developing the drip irrigation of water saving technology vigorously, and the fertigation technology in potato production is applied more and more widely. In practical production, growers usually used the conventional fertilizer which is difficult to dissolve, and cause drop head congestion. The liquid fertilizer is the ideal fertilizer for use in drip irrigation, which is dissolved completely, and has little impurity. In this research, basic fertilizer rate was appropriately reduced, and Nongjigao, a liquid fertilizer, was applied as additional fertilizer through drip fertigation at the rate of 10 kg, 20 kg, and 30 kg on the basis of 667 m2 land to study the effects of the liquid fertilizer on the growth, tuber yield and tuber characters of potatoes. The results showed that compared with traditional fertilization, the liquid fertilizer could increase potato tuber yield by 13.52% - 22.36%, marketable tuber percentage by 4.68% - 6.55%, and income by 401.85 - 527.95 Yuan on the basis of 667m2 land, suggesting that ＇Nongjigao＇ has potential to be extended for use in potato production.
