Fruit tree planting methods and techniques in spring

China Garden Network April 12th news: Fruit trees in the spring planting period, although the temperature is relatively warm, the rain is more, the humidity is high, the survival rate after planting is high, easy to grow new roots and new shoots, but if the method is not appropriate, it will also cause planting The post-survival rate is low. The methods and techniques for introducing fruit trees in spring are as follows.

First, choose seedlings. Choose high-quality seedlings without pests and diseases, strong growth, developed roots, short internodes, and no water loss. The trunks of the seedlings and the leaves on the branches are full of green and shiny.

Second, the application of fixed root fertilizer. 7 to 15 days before planting, the mountain orchard is based on the deep turning of the planting hole. The flat orchard is under the topsoil of the fruit pier, 0.5 kg of bean bran or peanut bran per plant, or 10 to 15 of pig beef fat. kg. Fertilizer should be thoroughly mixed with the soil, and should not be in direct contact with the root group to prevent burning of the root group, that is, the fertilizer should be applied 30 to 35 cm away from the planting point, or under the planting point, 35 to 40 cm from the topsoil, and Break the clods on the planting point and apply a small amount of fully decomposed manure water 3 to 5 days before planting to mix well with the soil.

Third, seedlings finishing. After the seedlings are transported back, they should be placed in a cool and sheltered place to keep the roots moist. If the number of seedlings is large, it should be graded according to size, graded, and properly trimmed to roots and shoots. Cut rotten roots, dried roots and roots before planting. The rotten roots are cut to the white, even if the roots are cut a little. Too weak or improperly positioned branches should also be cut off. When the weather is too dry during long-distance transportation or planting, a part of the leaves should be cut off to reduce water evaporation.

Fourth, planting. When planting, the roots should be straight and straightened, distributed evenly and slightly obliquely downwards in all directions in the planting hole. If the roots are broken down from the straight roots, the roots should be smoothed from bottom to top. Fill in the fine soil layer by layer and compact it by hand, but do not use too much force to prevent the root system from being crushed. When the soil is half filled, the seedlings are gently lifted to the soil, the roots are straightened, the plants are fixed, and the soil is filled with the feet. The covering soil cannot be higher than the grafting interface. Pillar support should also be provided to prevent the roots from being shaken.

5. Watering in time. After the saplings are planted, the roots of the water and the grass are moisturized. Within 5 days after planting, water is sprayed once a day, and water is sprayed once every other day for 5 days. After 20 to 30 days, the topsoil can be gently opened. If there is new root germination, one thin mature manure can be applied.

Sixth, scientific and fixed. After the seedlings are planted, according to the height of the seedlings, shortly cut at 50 to 60 cm full buds, then apply bio-oil or paint on the wound to prevent draining.

In order to prevent the fruit tree pier from sinking, according to the depth of the planting hole or ditch, the amount of grass should be buried to determine how high the fruit pier should be, so that the grafting interface of the seedlings after the subsidence is just exposed to the ground, thus benefiting the fruit trees. Growth and development.
