Cultivation techniques of fruit trees

In the cultivation technology of fruit trees, we should first choose good fruit tree varieties, and choose excellent varieties with pure seedlings and suitable for local natural environment conditions.

1. Look at the root system: the root system of excellent fruit tree seedlings should have more lateral roots and fibrous roots, which are evenly distributed. One or two seedlings should have more than three lateral roots, and the roots should not lose water.

2. Specification selection: the height of excellent fruit trees should be 1 ~ 1.3m, and the ground diameter should be 0.8 ~ 1cm. Grape Miao Di diameter is not less than 0.6 cm.

3. Germination status: There must be more than 6 full and full leaf buds in the shaping area below the fixed stem level, so that good branches can be produced after the fixed stem. Grape seedlings must have 3 ~ 4 full buds with high maturity.

4. Whether there are pests and diseases: choose seedlings without pests and diseases, and the seedlings that belong to the quarantine scope should have quarantine certificates.

The cultivation techniques of fruit trees should be suitable for the site and trees. In front of and behind the house, peaches, bayberry and pomegranate can be planted. ; Pears, persimmons, chestnuts and dates can be planted at the back and sides of the house. Potted kumquat, grape, fig, pomegranate and dwarf peach can be planted on windowsill, terrace, roof platform and low wall, and attention should be paid to the configuration of different varieties of fruit trees in early, middle and late stages.

Fruit tree cultivation technology, choose neutral soil with convenient irrigation, ventilation and light transmission, loose and fertile soil for planting. Most fruit trees are perennial herbs. To apply plantar fertilizer, the row spacing is 40-70 cm and the depth is 20-30 cm. Then, the land is leveled and made into a belt-shaped boundary with a width of 70 cm, and the boundary surface is higher than the ground 10 cm. Choose strong seedlings with a height of about 15cm, many branches, thick branches, lush leaves and no pests and diseases, and plant them in zigzag. Generally, it is more appropriate to plant it tonight. After planting, water the roots.

Management is very important in fruit tree cultivation techniques. Loosening and weeding are generally carried out 3-5 times a year to prevent soil hardening, and appropriate watering is used to cultivate soil and help seedlings. Ginseng needs a lot of fertilizer. Fertilizing according to the needs of plants and spraying Gendalin in time can promote the transportation of photosynthetic products (nutrients) on leaves to roots, improve the nutrient conversion rate and loosening ability, make roots swell rapidly and greatly improve the content of effective substances.

Pay attention to the cultivation techniques of fruit trees.

1. The dormancy period of fruit trees is from defoliation in winter to germination in the next year. At this time, almost all fruit tree diseases and insect pests began to hide in the wintering nest, unable to eat or move, and went into hibernation. Therefore, this is the best time to control fruit tree diseases and insect pests once a year.

2. After the trunk is painted white in winter, it can not only increase the pest control effect, but also help the fruit trees to prevent freezing. There are two kinds of whitening agents commonly used, lime-sulfur mixture and lime-copper sulfate mixture.
