In the spring planting period of fruit trees, although the weather is warm, the rainfall is high, the humidity is high, and the survival rate of the trees is high, new roots and new shoots should be grown. However, if the method is improper, the survival rate after planting will be low. This not only wastes money and manpower, but also has a great impact on early fruit production. The methods and techniques for spring planting of fruit trees are presented for reference by farmers. First, the selection of good seedlings is a guarantee of high quality and high yield. No pests and diseases are selected, and the growth is robust. The root system is developed and the internodes are short and thick. High-quality seedlings without water loss, the leaves on the main stems and branches of the seedlings are full of green and glossy. 2. 7-15 days before the establishment of sufficient root-fertilizers, the mountain orchards will deepen the planting holes, and the ground orchards will have 0.5 kg of fermented bean dregs or peanut slag, or pig cattle, under the surface soil of the Guodun Pier. 10-15 kilograms of manure, the fertilizer should be mixed well with the soil, can not be in direct contact with the root system to prevent burns roots, that is, the fertilizer applied 30-35 centimeters away from the colonization, or under the site of the colonization, 35-40 cm from the topsoil At the same time, the soil clods on the site of the planting site are broken, and 3-5 days before planting, a small amount of fully decomposed manure water is poured to make it mix well with the soil and absorb it. 3. After the seedlings have been transported, they should be placed in a cool and sheltered place to keep the roots moist. If the number of seedlings is large, they should be sorted by size, graded, and properly trimmed on the roots and treetops. Cut rot, roots and roots before planting. When the rot roots are cut to white, even a good one needs to be cut off a little, mainly to control the germs of the diseased roots and to stimulate the emergence of new roots. If the shoots are too weak or improperly positioned, they must be cut off. When the weather is too dry, a part of the leaves should be cut off to reduce evaporation. Fourth, when planting and planting, all roots should be straightened and straightened out. The direction is evenly distributed in all directions in the planting hole. Slightly obliquely and downwardly, if the lateral roots are divided into several layers from the straight root, they should be stratified from the bottom to the top. Shun, fill in the fine soil layer by layer, hand compaction, but do not use too much force to prevent the root system pressure, in the soil fill to half, gently raise the seedlings, straighten the roots, righting the plant, In the filling of soil with the foot compaction, the soil can not be higher than the grafting interface, but also should be set up to support the pillars to prevent shake the roots. 5. Immediately after watering and seedlings are planted, water is immediately poured onto the roots and the grass is moistened. Within 5 days, water is poured once every day. After 5 days, water is poured every other day. After 20-30 days, the topsoil can be checked. Such as the new roots germination, can be applied to a thin decomposed manure water, seedlings survived, should be diligently applied thin nitrogen fertilizer-based organic quick-impact liquid fertilizer. Sixth, after scientifically setting the seedlings, according to the height of the seedlings, a short cut at 50-60 centimeters, and then apply bio-oil or paint on the wound to prevent draining, which is conducive to the growth and development of fruit trees.
