Ankang Citrus Vesscosa High Yield And Cultivation Technology Research

Ankang is the most abundant heat resource in Shaanxi Province, the development of Citrus vesscosa has become this region people out of poverty important pillar industry. In recent years, with the development of social economy and the expansion of planting area,varieties of clutter, management extensive, diseases and insect pests serious, economic benefit is low, and other issues have become an obstacle and restricting the development of the industry.In order to promote the healthy development of the industry, the Citrus vesscosa better service in production, combining with geography, natural resources in southern Shaanxi Province, this study conducted in Ankang Citrus vesscosa high yield and cultivation technology research and achieved the following results:1. The research puts forward the Ankang Citrus vesscosa high yield and cultivation technology(1)the park site selection:at an altitude of 600 m below; slope below 20°; PH 5.5 ~ 7.5; sandy loam;(2)the seedling quality, choose good block grafting; root system developed, seedling height 1.0 ~ 1.2 m; ground diameter more than 1.0 cm;(3)soil preparation in advance, planting hole 1 m square, each hole applying composting manure 25 kg; flat planting density of 4m*5m, gentle slope planting density of 3m*4m; plant after watering, tree plate coated, the survival rate can reach more than 93%.2.Summarizes Ankang Citrus vesscosa main pests — Bactrocera minax comprehensive prevention and control technologyAdhere to the principle of combining biological control and chemical control, the key technical measures, timely picking fruit drop, removal of maggot fruit, and deep processing; in mid-may to mid-june, the appropriate use of drug prevention and treatment; before freezing the whole park plowing once; pest fruit rate can be controlled within 5%.Put forward the reasonable tree and soil management techniquesBy comparison test, Ankang Citrus vesscosa trimming should give priority to with natural heart-shaped; strengthen soil management at the same time, the organic fertilizer after picking fruit(the flourishing fruit trees 50 kg/each) at a time, to ensure high yield.Above research results, to promote well-being Citrus vesscosa industry healthy development has positive practical significance.
