March is the spring planting period of fruit trees. Although the temperature is warmer, the rain is more, and the survival rate after planting is high, if the method is not correct, it will also result in a low survival rate after planting. To master the scientific methods and techniques of fruit tree planting.
The seedlings are selected to be high-quality seedlings with no 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 solid and shiny.
7 to 15 days before the application of fixed-root fertilizer, 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 pig. Beef fat 10~15 kg. The 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 fixed point, or under the planting point, 35 to 40 cm from the topsoil, and Crush the clods on the planting point and apply a small amount of fully decomposed manure water for 3 to 5 days before planting to mix well with the soil.
After the seedlings are finished, the seedlings 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 by 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.
When planting and planting, the roots should be straight and straightened, distributed evenly and slightly obliquely downward 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.
Immediately after watering the seedlings to plant the soil, immediately rinse the roots and cover the grass to moisturize. Within 5 days after planting, water is sprayed once a day, and once every 5 days, water is sprayed once every other day. After 20~30 days, the topsoil can be gently opened. If there is new root germination, one thin mature manure can be applied.
After scientifically planting the dried seedlings, according to the height of the seedlings, shortly cut at 50~60 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.

Steroid hormones, also known as steroid hormones, are a class of tetracyclic aliphatic hydrocarbon compounds with a cyclopentane polyhydrophenanthrene nucleus. It has very important medical value. It has a clear role in maintaining life, regulating sexual function, body development, immune regulation, skin disease treatment and birth control.
Steroids include steroids (eg cholesterol, lanosterol, sitosterol, stigmasterol, ergosterol), bile acids and bile alcohols, steroid hormones (eg adrenal corticosteroids, androgens, estrogens),
