Walnut tree planting points
1, planting time Before planting, soil preparation should be carried out. Dig a hole a square meter and open the topsoil and the soil and soil. When the backfill is completed, the topsoil should be filled and the earth should be filled. How many seedlings are taken when planting, generally using a 45-meter row spacing, 33 plants per acre, a 1:10 ratio of pollinating trees, and applying a farmer's manure and topsoil per hole. Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.

It is not easy to be late when spring is planted. Therefore, walnut trees can be planted after the soil is thawed until late March. The earlier the time, the better.
2, seedling selection
The quality of seedlings directly affects the success or failure of the establishment of the park and the economic benefits. Therefore, it is necessary to choose the pure and excellent varieties, the main roots of the seedlings are developed, the lateral roots are intact, there are no pests and diseases, the branches are strong, the flowering is easy, the resistance is strong, and the general plant height is more than 1 meter. , The basal diameter is not less than 1cm, 2~3 years old with more fibrous roots grafted strong seedlings.
3, seedlings before planting
First trim the roots of the seedlings, cut the main roots to remove the new section, cut off the rot, cut the tiers according to the size of the seedlings, and tie the bundles according to a certain amount; each bundle of a bundle should be immediately put into the clear water to soak, the water depth is higher than that of the root, low In the grafting site is appropriate, soaking time more than 12 hours, so that the roots suck enough water. After the seedlings have enough water to absorb them, they are put in 2000 times ABT rooting powder solution and soaked for 5 to 20 minutes to increase the survival rate. After the 0.5% carbendazim solution is placed in the mash, they are quickly disinfected. Finally, muddy roots are used to prevent the seedling roots from drying out.
4, planting
When planting, first release water, water should be more than appropriate, and then fill the mixture of topsoil and farmyard fertilizer, put in the saplings, pay attention to the grafting site when the seedlings go north (because the tree has light, the grafting position can be adjusted north of the crown distribution, In addition, northerly wind blows northwest to prevent wind-breaking.) And it is necessary to straighten and then fill the earth. When filling, fill it from the Western Zhou Dynasty to the middle and keep it uniform. After filling with soil, it is advisable to gently raise the seedlings to the previous position, and planting should not be too shallow or too deep. If it is too deep, it is easy to grow poorly, and the slow seedling slows the survival rate; if it is too light, it is easy to lose water and cause dead seedlings.
5, post-plant management
After the seedlings are planted, the tree trays should be covered in order to prevent running. Film size 90cm2, first leveling the ground, when the film is covered with two plastic film center through the center of the seedlings, flattened and spread, and then use fine soil around the roots and seedling roots compaction, compaction to prevent wind blown film caused by loss water. The saplings after planting were dried and dried at full shoots of 60 cm to 80 cm. After the trunk is set dry, the tree trunk will be trapped with a special bag to prevent damage to the leaf insect pests such as beetles. After the temperature rises, the wind will be gradually protected and the bag will be removed. After the saplings have sprouted, it is necessary to strengthen the management of soil fertilizer and pests and diseases.
