1, technical points (1) Change the density. For the orchards with a spacing less than 4 meters and a spacing less than 2 meters, density reconstruction is performed. According to the standard of 45-55 strains per acre, it is adapted to local conditions. (2) Change the tree body. For tree crown height greater than 2.5 meters, the tree structure is disordered or the branches are handed over. The orchard with poor light should undergo tree transformation. (3) change the variety. High-risk alternatives, push down reconstruction. Replanted with good new varieties. (4) Change the soil. Every 2 to 3 years, deep plowing or troughing is performed, with a depth of 40 cm to 50 cm and a width of 60 cm or more; fertilizing the soil; grass cultivation to increase soil organic matter content. (5) change the method. Reduce fertilizer use. The orchards are mainly fertilized with organic fertilizers and supplemented with chemical fertilizers. The annual organic fertilizer consumption accounts for more than 80% of the total. The use of highly toxic, high-residue chemical pesticides is prohibited. Film coated with sugar. Promote fruit coloring and increase sugar content. (6) Change facilities. The capacity of the reservoir should be built at 20 cubic meters per mu of orchard. According to the requirements of electric power safety, the power supply to the field and the facilities are standardized to facilitate mechanical operations. With the construction of trunk roads and operation roads as the core, the operation road should ensure the normal passage of farming machinery and small-sized transportation vehicles. 2, increase production efficiency goals In the province's main fruit producing areas, 3 million mu will be demonstrated and promoted to further improve the quality of the fruit, and the mu will increase by 200 yuan. It is estimated that the added benefit will be 600 million yuan.
