Intensive cultivation of apple dwarfing anvil
The efficient cultivation of dwarfing anvil is a widely used cultivation technology in the world apple production advanced countries, and is also the development direction of China's modern apple industry. Vigorously promoting this advanced cultivation mode is of great and far-reaching significance in promoting China's apple cultivation system to be in line with international standards and realizing the strategic transformation of China's apple production from quantity-type to quality-type, from apple production to power production.
Technical points:
1, Da Miao built the park and set up a stand. Use 2-3 year old dwarf rootstock or dwarf intermediate stock large seedlings. Seed seedling height is 1.3 meters or more, and the diameter of the varieties is more than 1.0 centimeters above 5 centimeters above the interface; a 3. Migao's cement pillars are respectively equipped with a 12-gauge steel wire at 1m, 2m and 3m, and a bamboo pole is erected beside each tree to support the center to grow robustly.
2, the determination of planting density and methods. The planting density is determined by the growing variety, rootstock growth and soil fertility. Strong growing species (Fuji, Jonah, etc.) or better soil conditions and flat land, planted with larger plant spacing; weak growing varieties (Gula, U.S. 8, honey crisp, etc.) or poor soil conditions and sloping lands , using a smaller plant spacing planting. At the same time, there are different planting densities in different regions. It is generally recommended that the row spacing is 1.5 to 2 meters, 3.5 to 4.5 meters, and 74 to 170 plants per mu. The ratio of plants and row spacing is 1:2 to 3, suitable for wide-row planting. To determine the centerline of a good tree behavior, the ridge width is 1.2 to 1.5 meters, and the ridge height is 20 to 30 centimeters.
3, increase organic fertilizer, improve the soil. Before the planting, deep ditching and organic soil improvement were applied. The depth of the ditch was about 60 cm and the width was about 1 meter. Through soil improvement, the content of soil organic matter in the concentrated distribution area of ​​the roots reaches more than 1%.
4, between the rows of grass, tree cover. Plant artificial grass or natural grass in the orchard line. Artificial grass orchards can use clover, alfalfa, ryegrass, etc.; natural grass orchards to timely remove the vicious weeds. When the grass grows to 30-40 centimeters, about 10 centimeters will be castrated to cover the tree disk.
5, spindle-shaped pruning, help strong dry. Take spindle-shaped pruning to maintain the center of the stem upright and robust growth, after the completion of the shaping of the tree height 3 to 4 meters, dry height of 0.6 to 1 meters, the center stem spiral on the birth of 15 to 20 uniform lateral branches, lateral branch base roughness Not more than 1/4 of the dry thickness of the center of its place of birth; simplified pruning, reducing the number of branches and branches, the amount of acres after pruning in winter is controlled at 80,000 or so is appropriate.
