The Investigation And Evaluation Of Apple Orchard Management Model In Jingning County

This investigation with Chen Chuan,Li Dian and Jia He in Jingning County of Gansu province,each township selected three orchard,which were Chen Chuan orchard 1(C-1),Chen Chuan orchard 2(C-3),Chen Chuan orchard 3(C-3),Li Dian investigation orchard 1(L-1),Li Dian orchard 2(L-2),Li Dian investigation orchard 3(L-3)),Jia He investigated orchard 1(J-1),Jia He investigated orchard 2(J-2)and Jia He investigated orchard 3(J-3).In this paper,9 different management models of 14-17 year old apple trees were investigated,which mainly aimed at the investigation and summary of soil and fertilizer water,pest control and fruit tree pruning in orchard.Through the appraisal of the income and fruit quality of the year of the orchard,the most suitable model of orchard management was selected to provide the basis for the management of the orchard through a scientific model,and then to improve the yield and quality of the orchard.The detail results are as follow.1.After investigating the nine orchard management models,it was found that the growth of new shoots in the L-1 mode was 64.82 cm.J-1 orchard was 17 years old.The fruit tree was thickest at 21.56 cm,followed by orchard L-1,L-3,L-2,C-2,J-3 and orchard J-1.The principal component analysis found that the nine orchard management models were ranked L-3,C-2,J-3,L-1,C-1,J-1,L-2,C-3 and J-2 in order to speculate that the management quality of Li Dian orchard in Jingning county was higher.2.After investigating the input and income of these nine orchards,it was found that orchard mainly invested in thinning and thinning,artificial pollination,bagging,picking bags,picking leaves,turning fruits and harvesting.According to the output of orchard,total income and pure income,the nine orchard can be divided into high yield orchard,middle class orchard and low yield orchard.The high yield orchard has L-3,C-2,L-1,J-3,middle orchard with C-1,L-2,J-1,and low yield orchard with C-3 and J-2.The highest income L-3 planted 8 mu orchard with 20 thousand and 800 kg of high quality commodity fruit,25 yuan in total,208 thousand and 300 yuan in orchard net income and 26 thousand yuan in pure income,12 thousand yuan higher than that of middle class orchard,18 thousand yuan higher than that of low yield orchard.3.The fruit quality of the fruit orchard of the nine different management models was investigated.The fruit weight,coloring index and sugar and acid ratio of the fruit of Li Dian orchard were better.4.The management mode of high quality orchard in Li store was 2700 kg of bio organic manure and 120 kg of high nitrogen potassium compound fertilizer.The compound fertilizer of 80 kg of urea-calcium superphosphate-potassium sulfate was applied to 1:2:1 at the end of March.When picking leaves,turning fruit,laying reflective film,so that the fruit coloring.
