Study On Problems And Countermeasures Of Walnut Industry In Hanbin County, Shaanxi Province

Hanbin is located in the southeast of Shaanxi Province,the hinterland of Ankang City.Due to natural and historical reasons, there are many areas is still inaccessible in long term, low level of productivity,enriched resources are difficult to effective development and utilization,single industrial structure of agriculture, agricultural production capacity is weak, narrow channels of farmers’ income, the employment situation is grim, the absolute level of income is low,the problem of slow agricultural growth still exists.In poor condition of agricultural production,limited sources of income of the farmers,under the difficult to increased the income, an increase in migrant workers, local farmers urgently need to find a way to make full use of local advantages of resourcesform a large-scale, sustained and stable way of income, changes in rural economic situation fundamentally improve the income level of agricultural producers.In recent years, in order to make full use of local advantages of resources to enable farmers to find practical ways to increase revenue, it is critical to discover potential problems and to be addressed.In this paper,we combine the home visits and fieldwork investigation method,we analyze and comprehensive evaluation the local walnut cultivation and management problems and by selecting the orchard address,the relationship between different cultivation management,soil composition and walnut growing differences, put forward the corresponding countermeasures to accelerate the development of Hanbin walnut industry.The results show, select Walnut Address, that elevation, slope position, slope direction have different influences on the walnut growing.In addition, there are factors in the growth of walnut planting density, interplanting mode and fertilization, pruning and other factors.(1)With the rise of sea level, it has an excellent walnut plants growing its share has increased, indicating planted walnut in the appropriate range, altitude and growing presence of certain positive correlation.(2)In terms of slope position, on the whole walnut growing with rising slope position was a negative correlation.(3)The proportion of plants with walnut slope from the sunny, semi-sunny, semi-shady slope to change, with excellent growing gradually reduced, further evidence of walnut favored plant.(4)With the planting density increases, the worse the overall growing walnut trees, walnut trees growing and planting density negatively correlated. In the three cases in intercropping, interplanting dwarf walnut growing crops generally good, good good walnut growing than the highest, followed by pure forest, high bar interplanting than the minimum described interplanted crop of dwarf walnut growth has some positive action, high bar interplanting growth there is a certain negative impact on walnuts.(5)Hanbin District of soil survey found widespread soil nitrogen deficiency Hanbin phosphorus and in the daily management should be more nitrogen and phosphorus.(6)Pest survey results, along with the deepening of pests in Walnut, the proportion of the tree has excellent growth rapidly decreased, indicating pests constitute a very adverse effect on the normal growth of walnut. Therefore, in the process of development of the walnut industry, in the development of Walnut Park site should be selected, and the process of planting pay attention to proper planting density, not when interplanted tall crops interplanting, daily management to be more emphasis on nitrogen and phosphorus and pests prevention.This study attempts to analyze the problems and current development of the walnut industry in Hanbin,trying to identify the variety of factors that constraints Hanbin walnut industry development:(1) Walnut site selection unreasonable.(2) Planting management problems.(3) Aging seedlings and seedlings more varieties messy, irrational structure.(4) The problem of widespread barren soil. Proposed the development of the walnut industry Hanbin feasible suggestions:(1) The development of Walnut, required in accordance with the principle of suitable tree.(2) Strengthening walnut management skills training, improve fruit quality, improve fruit quality.(3) Suitable breeding local varieties, varieties for regional harmonization.(4) To strengthen links with the outside world, cooperation, attract investment.(5) Scientific and rational fertilization.This research is important for the healthy development of the walnut industry of Hanbin.
