Natural Resources Survey And Excellent Individual Along With Cultivate Technology Research On Qinghai Pear Trees

The project was designed to investigate and study surrounding resources species and distribution of the pear trees focusing on the vacancy of pear trees research in Qinghai Province, on the basis of knowing resources, selection of fine individual was studied, fine individual was selected; the study of the growth activities and cultivation techniques of the twigs and fruit of pear trees was carried out, then the cultivation techniques of pear trees in Qinghai Province was putted forward.1.By the analysis and study of resources survey, inquiring the distribution range,distribution species and distribution quantity of pear trees resources in Qinghai Province. the resources of pear trees is distributed mainly in Guide county,Ledu county and Minhe county. The total resources of pear trees amounted to 10863 plants in Minhe County; it was 13.8% of the total resources amount of three county distributions. Among them, Soft Pear were 7537 pants ,accounting for 64.9% of the total resources amount in this county; Winter Fruit Pear were 3326 plants ,accounting for 30.6% of the total resources amount in the county. the total resources of pear trees amounted to 48499 plants in Guide county, accounting for 61.7% of the total resources amount of three county distribution. Among them ,Soft Pear were 28181 plants, accounting for 58.1% of the total resources amount in this county; Long Handle pear were 20318 plants, accounting for 41.9% of the total resources amount. The total resources of pear trees amounted to 19265 plants in Ledu County, accounting for 24.5% of the total resources amount of three county distributions.2. Fine individual of Qinghai pear trees was selected in this study. After analysis and comparison of the index as grows,yield,quality,antibiotic activity, three fine individual were selected ,which were Soft Pea(rGAR supply1),Long Handle pea(rGHDC supply2),Winter Fruit pear(MMCYD8).3. The growth activities of the twigs and fruit of Soft Pear were studied, it provided scientific basis for the high yield cultivation and management of pear trees.4.The high yield cultivation technique,form-pruning techniques,Arrangement techniques of pollination tree,the fruit-bagged techniques,the pest control techniques and the cultivation technical specification of Soft Pear were putted forward by study...
