| Abstract: | The effect of nitrogen,phosphorus and potassium coordination employment on the yield of first order non-poisonous potato protospecies and the quantity of seed tuber was explored.The results indicated that the best application fertilizer scheme of potato yield was as follows: manure 11 250 kg/hm2,nitrogen fertilizer 172.5 kg/hm2,phosphatic fertilizer 75 kg/hm2,potassium fertilizer 150 kg/hm2,N∶P∶K was equally 1∶0.4∶0.9.Thus,the output reached 30 481.5 kg/hm2,and the ratio of products and investment was 3.1∶1.The best application fertilizer scheme of potato seed tuber was as follows: nitrogen fertilizer 156 kg/hm2,phosphatic fertilizer 85.5 kg/hm2,potassium fertilizer 120.5 kg/hm2,N∶P∶K was equally 1:0.55:0.77.Thus the quantity reached 158 055 per hectare. |
