A, planting method:
1, walnut is not strict on environmental conditions. General altitude of 500-1500 meters, the average annual temperature of 9 ~ 16 ℃, annual rainfall of 800-1200 mm, sandy loam or containing calcareous soil, PH6.5-7.5, the soil is deep, loose, fertile, well-drained places can be planted.
2, the soil is too sticky, too wet, poor drainage soil should not be planted. Walnut is a light-loving fruit tree, requires sufficient light, in the mountainous areas of the establishment of the garden should choose the best southward slope.
3, land preparation is to improve the survival rate of walnut cultivation and growth and development of an important link. The time for land preparation is generally half a year before afforestation. The way of land preparation can be selected according to the conditions of walnut orchard: generally the slope is below 10 degrees or flat land, the use of comprehensive land preparation.
4, according to the planting of the plant spacing, with the trend of the slope into a reverse-slope terracing, the slope is greater than 20 degrees, with the fish scale pit land preparation. That is, in the planting point into a small platform, the following with stone masonry can. At the same time, according to the planting density, digging planting pits in the whole garden, generally require 1 meter square, digging pits when the soil is placed in layers.
5, walnut sapling branch pith, high water content, so the ability to resist cold is poor, in the more cold, dry areas are prone to frost damage, resulting in dry branches. Therefore, in order to ensure the normal growth of young walnut trees, winter cold work is very important.
6, in the walnut seedlings at the base of 30 centimeters within the cultivation of a mound of soil, which can effectively increase the thickness of the protective layer of soil root system, like to give it more cotton clothes, so as to achieve the effect of cold.
7, through the trunk of the seedlings white way, can effectively relieve the temperature difference between the sun and shade of the trunk, cold effect is very good. Commonly used whitening agent formula: salt, quicklime, water at a ratio of 1:12:30 preparation, preparation can be added to the appropriate amount of adhesive to increase the effect of its coating.
Two, planting management:
1, planting time in late March before and after budding, planting 1 ~ 2 years old seedlings survival rate is high, should be watered thoroughly after planting, and strengthen the management of water and fertilizer, selection of Ramla special fertilizer, frequent loosening of the soil and weeding, pay attention to the drainage of the rainy season, pay attention to the control of pests and diseases in June-July.
2, growth period should be pruning, dry height to maintain above 3m. Do not cut branches after leaf fall, otherwise it is easy to cause injury flow, affecting the growth of trees.
3, planting time deciduous fruit trees in winter is generally appropriate, evergreen fruit trees in spring is appropriate, planting should be done to achieve specification, to achieve horizontal and vertical rows.
4, when planting the grafted mouth should be exposed to the ground, the root system should be stretched, and then cultivate the soil, stamping, irrigation, water seepage and then seal the hole, in order to facilitate the preservation of water.
5, tree body tall walnut tree life long, hundreds of years of large trees can still maintain a high yield. Tree tall, thick branches and leaves, a large walnut tree crown diameter of up to more than 10 meters, covering an area of 100 to 200 square meters.
Three, walnut tree can be used as road greening protection forest; because of its tough wood, elasticity, is also used in the industry of superior materials. Walnut shells can be processed into works of art. Walnuts and walnuts, cashews, hazelnuts in the international market is known as the "four nuts".
Four, walnut tree, the trunk of the adult tree on the different species, its height is generally in the 2 ~ 10 meters, high or more than a dozen meters; broad crown; bark gray-green when young, old gray and longitudinally fissured; twigs glabrous, glossy, peltate bearing glands, gray-green, and later with brown.
Expanded Information:
1, walnut tree crown majestic, white trunk, branches and leaves, green shade cover the ground, in the garden can be used for road greening has a protective effect.
2, walnut tree wood tough, elastic, fine grain, beautiful color, commonly known as false rowan wood, is the military and furniture industry to use the best materials.
3, walnut shells can be processed into works of art and beautiful, its shells are hard, not easy to deteriorate.
4, walnut fruit ripe in August to September after the harvest, peeling, drying, drying and hiding. mid-March will be soaked in cold water for 2-3 days, fish out and mixed with wet sand, piled up in a sunny place. High 30~35cm, covered with l0cm thick wet sand, sprinkle water 1 time a day to keep wet, evening cover grass curtain or film moisturizing insulation, 10~15 days shell cracking, white can be sown. Pick 1 time a day, batch sowing, sowing should be enough moisture sowing.
