The branches and vines of Schisandra chinensis are soft and cannot stand upright, and they need to be attached to a bracket to grow upward. Therefore, its plastic work includes two tasks: setting the bracket and pruning.
(1) Set the support
The growth of Schisandra chinensis in different planting years is very different. Under the condition of poor seedling quality and poor management, the plant height can only reach 50 ~ 60 cm, but the average growth height can reach 150 cm in the second year after pruning, and the frame surface can be covered in the third year. Therefore, it is generally possible to erect the scaffold in the spring of the following year (mid-May). The bracket can be made of poles and sunscreen polyethylene ropes. Most of the shoulder poles are bamboo poles, with a length of 2.0 ~ 2.2 meters and a head diameter of 1.5 ~ 2.0 cm. 3 15 polyethylene rope with suitable thickness for sun protection, and its upper end is fixed on the first iron wire on the upper part. According to the plant spacing of 1 ~ 2 per plant, when the plant spacing is less than 50 cm, 1 plant can be set for each plant and placed about 5 cm beside the plant; When it is more than 50 cm, each plant should be evenly inserted or fixed on both sides of the plant. The soil part of the bamboo pole should be coated with asphalt to prolong its service life, and the pole should be fixed on three lines with thin iron wires. In the Schisandra chinensis garden with good seedling quality and management, the plant growth height in that year can reach about 2 meters. Therefore, scaffolds should be set up in late May of the year of planting to promote the rapid growth of plants.
(2) Plastic surgery
The purpose of shaping Schisandra chinensis is to make it grow and develop according to the requirements of growers through human intervention and induction, make full use of shelf space, effectively use light energy, reasonably reserve branches and vines, adjust the relationship between vegetative growth and reproductive growth, cultivate healthy and long-lived plants, make them adapt to climatic conditions, and facilitate farming, pest control, pruning and harvesting, thus achieving the goal of high yield, stable yield and high quality.
The tree shape of Schisandra chinensis is usually 1 or two groups of main vines, that is, each plant chooses 1 or two groups of main vines, which are respectively wound on evenly arranged brackets, and L ~ 2 fixed main vines are reserved on each bracket, and each main vine is provided with lateral vines and fruiting mother branches, and the spacing of each fruiting mother branch is 15 ~ 20cm, which is evenly distributed, so that. The advantages of this shaping method are that the tree structure is relatively simple and the shaping and pruning technology is easy to master; Cultivation can be carried out between plants, which is convenient for weed control; The volume and load of the workshop are small, and the requirements for soil, fertilizer and water conditions are not strict. However, because the plant is relatively upright, it is easy to form a situation that the upper part is strong and the lower part is weak, and the result part moves up, which needs to be strengthened.
