Only 30 centimeters in height and only 15-20 centimeters in trunk, the chestnut super dwarfing cultivation can produce high yield early. Chestnut super-dwarf, high-yield and high-quality cultivation techniques are implemented, which is conducive to tree management and reasonable close planting. It is beneficial to enter the result period and the high yield period early. The key technologies are as follows.
1. The dwarfing anvil Jinpingshu is similar to the original species, but the tree is mushroom-shaped, nearly flat-topped, the trunk is short and obvious, the main branch and lateral branches are diagonally spread, and the base and trunk are 45-50 degrees. At the end of the fall, the branchlets drooped. Nuts fan spherical or spherical, single fruit weight 8-10 grams, the general management conditions under the strain of 5-10 kg, the quality of the upper. Under the same environment and cultivation conditions, compared with common chestnut anvil trees, the dwarfing rate of Jinpingxiaoshu as an anvil is as high as 30%.
2, special plastic dry height only 30 cm, leaving the trunk only 15-20 cm. Dwarfism can dwarf the tree body and reduce the tree crown, which is beneficial to increase the number of plants per unit area and achieve the purpose of early high-yield production. No center dry, single-leaf curtain, opening in a round shape, favorable ventilation and light transmission. Take many summer toppings to promote branching and improve branch order to quickly complete the tree for early results. Specific operation:
1. In the first year, in the early spring, the short height of the seedlings was set at 30 cm. When the sprouts were budding, the shoots were germinated below 20 cm, and 3-4 branches above 20 cm were allowed to grow for one year.
2. In the second year, in the early spring, all vigorous annual branches were cut off from the trunk at a distance of 30 cm, leaving no center dry. In this way, new shoots will inevitably grow well. Around the middle of May, 1-3 cuppings are performed to promote secondary shoots or three tips. Entering the dry season in July, these shoots are generally 20-30 cm in length, and then they stop growing due to drought, etc.
In the third year, under adequate fertilization, the branches on the plant can generally become the result of the mother branch. Each mother branch can produce 2-3 result branches, and each result branch in May can appear 2 Above the female flowers, and the formation of the overall results. For vigorous growing branches should be picked up at about 30 cm. The extension should still be slanted around, removing most of the male inflorescences and erasing all the shoots that germinate in the autumn. In this way, tree shaping can be completed in 3 years after planting, and it can enter rich production period in 4 to 5 years.
3, supporting measures 1, scion varieties must be excellent. Must be selected for the local variety.
2, must configure the pollination varieties. We planted with the combination ratio of Qingzha, Xiaozha, and Shushu Hongyou strains.
3, must strengthen the management of fertilizer and water. For 1-2 year-old saplings, thin fertilization is applied. From April to August, 50-100 grams of urea are applied every month to enter the dormancy period in winter. Combined with deep-turning soil, 30 kg of compost is applied per plant and 0.25 kg of ternary compound fertilizer. After entering the 3rd year of the result period, appropriate fertilization will be carried out in stages: the first topdressing will be about 0.5kg per urea in the early to late April; the second topdressing will be 0.3kg per urea from July to mid-August. Calcium superphosphate 1.0 kg and potassium sulfate 0.5 kg; the third is basal fertilizer, combined with deep plowing to improve the depth of compost 50 kg.
