Cultivation and management of orange bonsai, making spring orange bonsai bonsai how to prune orange trees

   recently saw in Wu Xuefen Orange Garden, a citrus science and technology demonstration household in Xiaotang Township, Xiangshan County, that he had another "science and technology" project this year-- citrus bonsai.

   Wu Xuefen earned 300000 yuan from growing tangerines last year, of which Chunxiang was the biggest, accounting for 2/3. Chunxiang varieties are not only sweet, tasteful and mature, but also have beautiful fruit shape, personality and appeal. "wouldn't it be nice for residents who have the conditions to plant a few plants at home for people to watch?" So he had a whim and planned to cultivate citrus bonsai.

   Wu Xuefen told reporters that he bought green plastic buckets specially from Sanmen and planted 300 plants in mid-April. "each pot costs 200 yuan, and it can be sold now." In this regard, he is full of confidence.

  1. Select a container

The containers of    potted fruit trees are mainly round, so that the roots can spread evenly around. At the same time, the containers need to be permeated and breathable to ensure the oxygen demand for root growth and prevent the rotting roots caused by stagnant water in the containers.

   in all kinds of texture containers, sukiyaki pot is the most suitable for planting fruit trees. When using other texture containers, in order to overcome the disadvantage of poor air permeability, you can lay 5 cm thick coarse sand at the bottom of the basin, pad a layer of new tiles along the inner wall, and then fill the soil to plant trees.

   II. Soil, fertilizer and water management

   1. Preparation of basin soil

The basin soil suitable for the growth of fruit trees in    is generally neutral (PH value is 4.5 Mel 7.5), sandy loam or sandy soil rich in humus. When preparing, 4 parts of ripe pastoral soil, 2 parts of river sand, 1 part of plant ash, fully mixed evenly, crushed and screened. The culture soil should be disinfected before use, such as cooking disinfection, baking disinfection or medicine (1.5% formalin) disinfection.

   2. Fertilizer and water management

   because the root system of fruit trees can only absorb nutrients from the basin, only the organic fertilizer in the basin can not meet the needs of the growth and development of fruit trees, so we must pay attention to fertilizer and water management during the growing period. Fertilization should be based on organic fertilizer, reasonably mixed with chemical fertilizer, mixed with rotten organic fertilizer before sprouting, with an appropriate amount of phosphate fertilizer, about 1 kg of fertilizer and water per plant to promote sprouting and blooming neatly; extra-root topdressing in the fruit setting period after flowering, 0.3% potassium dihydrogen phosphate plus 0.3% urea, sprayed twice every 15 days to promote the expansion of young fruit and the growth of new shoots. Applying phosphorus and potassium fertilizer at 20 tons 30 days before harvest, applying 40 grams of potassium dihydrogen phosphate in each pot, and then pouring water thoroughly can increase the number of fruits and improve the quality. After the fruit was harvested, the ternary compound fertilizer was applied again and watered. Before the defoliation of fruit trees in autumn, rotten soil fertilizer was applied as base fertilizer. Watering should be strictly controlled during the dormant period, so that the basin soil is only dry.

   3, pour the basin

Because the nutrients in the potted soil are absorbed by the fruit trees or washed away in frequent watering,    needs to be emptied in time every 2-3 years to replace the new nutrient soil. After the lump of soil is deducted upside down, cut off the 3cm thick old root around the basin soil, mix the organic fertilizer and nutritious soil to fill the bottom, then bring the lump of soil into the basin, and then add fertile soil around to fill it, and pour water once.

   III. Crown control plastic surgery

   1. Choose the shape of potted fruit trees. According to the different requirements of upright and sagging of fruit trees and varieties, you can shape imaginative trees, such as natural round head shape, tower shape, single-branch cliff shape, two-branch deer horn shape, three-branch cup shape, weeping willow shape, dragon curve shape and so on. It should not only be beneficial to the result, but also have aesthetic effect and improve its ornamental value.

   2. Spray shaping applies chemical control technology to dwarf the tree. In summer, foliar spraying plant growth retarders (such as dwarf, paclobutrazol, etc.) should be applied three times in the vigorous growth period of potted fruit trees, which can make the branches stout, the internodes shorter and the plants dwarf. In addition, the main measures to promote flower dwarfing and shape pruning are: wiping buds, picking hearts, taking branches, twigs, ring cutting, retraction, renewal, pulling branches and so on. And through the opening branch angle and thinning long branches, dense branches and ineffective branches and other methods to enhance the light to form an ideal tree shape.

   IV, Flower and Fruit Management

When there is a large amount of flower buds in fruit trees,    should thinning flowers in the bud stage, fruit thinning should be carried out after the physiological fruit drop period; if the number of flower buds is small, more flowers can be left. Artificial pollination should be carried out at the same time.

Shaping and pruning according to the design, through curved stem, curved branch, circle branch, cylindrical shape, oblique stem shape, double stem shape, fan shape, vertical branch type and other shapes, in order to enhance the aesthetic feeling and promote the growth and fruit of potted trees.
