In consideration of the climate and geography conditions at Jiuchang township, Xiuwen county, 3 (typical) profiles of upland yellow soil were inspected for physical and chemical characteristics and soil water characteristic curves. The condition of agro-chemistry were analyzed for farming land soil. The utilization measures of farming were proposed in view of the soil characteristic.

Journal of Changjiang Vegetables (2008)

Free-virus potato seed were used to investigate the dry matter accumulation and nitrogen, phosphorus, potassium nutrition characteristics of Hui-2, a high yield potato cultivar. The result showed that the nitrogen (N), phosphorus (P2O5) and potassium (K2O) absorption rate in the leaves were kept paces with the dry matter accumulation rate which showed a double-peak curve , the peak appeared during the seedling to squaring stage and full flowering to late flowering stage respectively. The dry matter accumulation and nutrition absorption had a single-peak curve in the tubers and the peak appeared in wilting stage. Full-bloom stage to wilting stage was the main stage of dry matter formation and nutrition accumulation. Before the final flowering stage, the distribution of dry matter and nutrition in leaf was larger than in tuber, after that, the trend was reverse. The absorption ratio of nitrogen, phosphorus and potassium of Hui-2 were nitrogen (N)∶ phosphorus (P2O5)∶potassium (K2O) = 1∶0.140∶1.919, that is, the absorption amount of N, P2O5, and K2O for formation of 500 kg tubers was (N) 2.756 kg, phosphorus (P2O5) 0.310 kg and potassium (K2O) 4.256 kg respectively.

Free-virus potato seed were used to investigate the dry matter accumulation and nitrogen,phosphorus,potassium nutrition characteristics of Atlantic by pot experiment.The result showed that the plant grew rapidly during the earlier growing stage,and the tuber emergence was early.The accumulation rate of root was fastest in bud stage while stems and leaves were in squaring stage and tuber was in flowering stage with the same trends of absorption and accumulation of nutrition.During the earlier growing stage,dry matter and nutrition distributed main in leaves.With the development of plant and the tuberization and expansion,the distribution in tuber ascended and reached over 80%.The relativity of accumulation of dry matter,nitrogen,phosphorus,potassium and the days after emergence for Atlantic can well fitted with trinomial function.The absorption ratio of nitrogen,phosphorus and potassium of Atlantic were nitrogen(N)∶phosphorus(P2O5)∶potassium(K2O) = 1∶0.175∶2.142,that is,the absorption amount of N,P2O5,and K2O for formantion of 500 kg tubers was(N)1.609 kg,phosphorus(P2O5) 0.281 kg and potassium(K2O) 3.445 kg respectively.

Five new strains of potatos breeded by 60Co-γ ray radiation were identificated. The result showed that the yield of F8-02, 17.9 kg higher than plot of Favorite(CK) with the increasing rate of 79.2%, was the highest among the tested treatments. F8-01,with the yield of 5.8 kg and increasing rate of 25.7%, was the second most yield increase strains. Compared to CK,both F8-02 and F8-01 showed resistance to potatos late blight and comprehensive characters.

The field experiment was conducted with potato seeds soaked by Tianda-2116 for 12h.The results showed that different soaking concentration had different regulation effects on growth,yield and quality of potato.Tianda-2116 increased root activity,chlorophyll content in leaves and yield of potato and also improved quality.The application of 5.0 g.kg-1 had significant effect,yield was increased 23.8% than CK,big tuber rate was 40.50%,and the content of dry matter,protein,starch and reducing sugar were 21.85%,24.82%,18.36% and 23.36% higher than control,respectively.
