There are quite a few kinds of blueberries on the market at present. What Bian Xiao wants to introduce to you today is the variety of Lanfeng blueberry. So what are its characteristics? What are the planting techniques? After reading the following, I fully understand!
1. What are the characteristics of Lanfeng blueberry?
Lanfeng blueberry is a mid-mature variety bred by hybridization in New Jersey, USA, which is characterized by vigorous growth and strong drought resistance.
Extremely high yield and strong continuous high-yield ability.
The fruit is big, light blue, thick in fruit powder, hard in flesh, dry in pedicel and light in flavor.
The potential of the tree is medium, with a height of 1.2~ 1.8 meters, which is upright and gradually opens after fruiting.
The plant spacing is (0.6 ~ 1.5) 3m, and 330 saplings can be planted per mu.
The yield per mu is about 2000 Jin in the full fruit period.
Second, planting techniques of Lanfeng blueberry
1, preparation before planting:
(1) Fixed-point: When the fruit tree is fixed-point, it is made of bamboo or hemp stalks, and the lower end is cut into a wedge shape for easy insertion into the soil. When measuring the planting point, first measure a baseline according to the terrain, houses or roads, then measure a line perpendicular to the baseline, and then mark the position of each fruit tree with measuring rope according to the predetermined plant spacing and mark it with white ash.
(2) Excavation: excavation can be started after the fixed point is set.
The size and depth of the tree hole depends on the soil conditions. The sand is loose and the roots are easy to stretch. The tree hole can be slightly smaller, with a diameter of 80 cm and a depth of 70 cm. Clay soil is sticky, and the root system is difficult to extend. The diameter and depth of the tree hole need to reach 1 m.
2. Planting period:
(1) Fruit trees are generally planted from the end of June to the end of March in 10.
The autumn planting period should be as early as possible after deciduous fruit trees and before soil freezing. The spring sowing date is suitable after the earth thaws and before the fruit seedlings germinate.
The advantage of autumn planting is that the planting time is earlier and the ground temperature is higher, which is beneficial to root activity, and even new roots will grow in that year, thus reducing the delay time of seedlings in the next spring and improving the growth of surviving seedlings.
(2) The fruit seedlings bought in early winter can't be planted in the ground, but can only be followed indoors, in the yard and in the greenhouse.
Stay in the field until the next spring.
The method is to cultivate seedling roots with fine sand or fine soil and water them effectively.
Before planting, please soak the seedling roots in clear water for 2- 12 hours, then dip them in mud and cultivate them with fine soil. After the soil is cultivated, it must be watered thoroughly.
(3) When the branches are pulled apart, they will peel off, which will cause confusion of the trees and affect the young trees' fruiting and early high yield. The following measures should be taken for stripping: if the branches grow vigorously and baldness is serious, thinning should be carried out, and measures should be taken to promote the germination and branching of bare segments on the branches; Sparse useless branches to improve illumination; Strips with growth and development space can be leveled and transformed into fruiting branches.
Precautions for opening branches: fasten the rope, and don't pull the branches into an arch. For the upper and lower branches of the crown, all branches should be pulled out to facilitate the balanced growth of plants.
3. New shooting management
Thinning new shoots and weak branches that do not bear fruit, combined with pulling, kneading and propping branches, makes the distribution of branches reasonable, and the illumination inside and outside the crown is sufficient and even, which not only promotes nutrient synthesis and branch enrichment, but also promotes fruit swelling and coloring, and reduces wound rot caused by thinning branches in winter.
Pay attention to leave branches on your back properly to prevent burning branches every day.
4. Pruning can adjust the relationship between fruit trees and environment.
Adjust the quantity and quality of organ formation, adjust the absorption, transportation and distribution of nutrients, and thus adjust the relationship between fruit tree growth and fruiting.
Correct pruning can improve the lighting conditions in the tree, increase the area coefficient of young leaves, make mature leaves distribute in layers, form a good leaf curtain structure and make full use of light energy.
It can also adjust the relationship between individual structure and group structure of fruit trees, improve ventilation and light transmission conditions of orchards, and use space more effectively.
Maybe many friends have eaten Lanfeng blueberry. After all, it is still common in the market, mainly because it has many benefits to the body.
