In recent years, the enthusiasm of the peasant friends in the city to develop thin walnuts has been high. In order to improve the survival rate of plants and promote their rapid growth, early results should be achieved as soon as possible, and the following points need to be grasped in planting techniques:
1. Seedling quality. Selection should be pure, vigorous growth, full buds, no pests, high-quality root grafted grafted plants, require 80 cm above the seedlings, root diameter 1.2 cm or more, within the plastic belt full of 7 to 8 leaf buds.
2. Variety requirements. The suitable cultivars were Liao 1 and Liao 7 with early results, high yield, few diseases, and a high rate of 60%.
3. Planting time. It is advisable to use it before mid-to-late March.
4. Planting density. Plant spacing 3 meters 5 meters.
5. Expand hole fertilizer. Digging length, width and depth are 60-80 cm tree pits. It is recommended to apply 10 kg of manure or 20 kg of manure dung for high temperature fermentation in each tree pit, add 0.5 kg of double green manure, and mix it with the soil on the top surface and fill it in the pit. It is forbidden to use unfermented raw manure in order to avoid burning the root system.
6. Planting methods. First, fill the pit with 2/3 of the topsoil after mixing. If it is a sandy beach, fill in 5 to 10 centimeters of good soil at the bottom of the pit, fill in the top soil of the mixed fertilizer to 2/3, and then place the seedlings. . When planting, the root system will be stretched and the seedlings will be straightened. The seedlings will be gently raised upwards when filling with topsoil to make the root system fully contact with the soil. The depth of planting should be equal to the level of the neck and the ground. Watering in time after planting promotes survival. Then pour water every 10 days.
7. Fix it. Due to the habit of injuring the walnut trees, the pruning during the dormancy period is prone to injury. Therefore, the drying time is the budding period, and the dry height is generally 80 to 90 cm.
8. Anti-draw. Just planted walnut seedlings spring prone to pumping phenomenon. After the planting is completed, the tree must be wrapped with plastic film in time, or the tree seedlings should be put on a plastic tube, and the soil in the lower mouth should be buried strictly. After three months of planting, winter measures should be taken.
