How to grow BlackBerry

In order to grow BlackBerry, it is necessary to choose good breathable soil, drain and irrigate regularly in the process of planting, carry out regular ploughing and weeding in the garden, fertilize and irrigate the BlackBerry garden in spring, cover with straw and wheat straw, and manure regularly to ensure the nutrients needed for BlackBerry growth, and pruning at the right time can promote the better growth of BlackBerry seedlings. We should also pay attention to the prevention and control of insect pests in the process of planting.

Blackberries are somewhat similar to raspberries, and beauty is easier to grow and easier to grow.

1. Soil requirements

The soil growing BlackBerry requires good air permeability, and the thickness of the living soil layer in the orchard is preferably about 40cm. Their roots are distributed in 10-30cm soil, and the content of organic matter in the soil should be at least 1%.

When building a BlackBerry garden, if you are in a barren mountain or hilly area, trench the permafrost in the yard according to the row spacing of planting blackberries in autumn and winter, and fill the ditches with wheat straw, leaves and withered grass rich in organic matter.

In order to prevent damage to the roots of BlackBerry trees, BlackBerry gardens that have been built should be turned deeply into the soil after they are pruned and put on the shelves in late autumn and before sprouting in early spring next year. To avoid damaging the roots of BlackBerry trees, they should be turned shallow near the roots and deep away from the roots, so as to ensure that the soil in the BlackBerry orchards is loose and rich in organic matter.

2. Drainage requirements

From March to April to the sprouting period of BlackBerry branches, from May to June after flowering to the young fruit expansion period, and after the fruit was harvested in August, if the weather is relatively dry, you can irrigate once respectively. When the fruit trees mature in July, if the weather continues to dry, they should be irrigated every 7 days or so. Generally, as long as the irrigation can soak the soil 15-30cm, it is necessary to reach 60-70% of the maximum field capacity. Drip irrigation, hole irrigation and other methods can be used for irrigation.

If the tenth of the BlackBerry Garden is lower or the groundwater table is relatively high, in the season with more Rain Water, in order to prevent BlackBerry sound waterlogging, the BlackBerry Orchard should be drained in time.

3. Weeding

Weeding should be done frequently in the first two years of the BlackBerry planting garden, generally 6-8 times a year, and only 3-4 times a year after the BlackBerry orchard is completed. Ploughing and loosening the soil in time can keep the soil moist, eliminate weeds in the garden and promote BlackBerry growth.

4. Coverage

After fertilizing and irrigating the BlackBerry garden in spring, the border of the BlackBerry orchard can be covered with rice straw and wheat straw. the thickness of the cover is generally controlled at about 5-8cm, and the soil in the garden should be turned over once after 3-4 years of continuous mulching.

5. Fertilization

In order to ensure the better growth of BlackBerry, in the process of planting BlackBerry, we mainly apply high-quality organic fertilizer, supplemented by chemical fertilizer, so as to maintain and increase the indecent assault in the soil, and improve the structure and biological activity of the soil to a certain extent. when applying fertilizer, it is necessary to prevent harmful substances from fertilizer from entering the soil to cause pollution to the environment.

Base fertilizer application: generally apply base fertilizer to BlackBerry orchard in late autumn, mainly spread organic fertilizer after high temperature fermentation or retting, can be mixed with a small amount of chemical fertilizer, the amount of organic fertilizer should be calculated according to 1.5-5kg fertilizer per kilogram of BlackBerry, generally 45~60t/hm2 organic fertilizer needs to add 450~525kg/hm2 diammonium carbonate, 50~600kg/hm2 potassium sulfate and so on. In order to increase the yield of BlackBerry, the amount of organic fertilizer applied can be increased to more than 75t/hm2. If the local fertilizer resources are scarce, the amount of fertilizer should be up to one kilogram per kilogram of BlackBerry.

Topdressing: according to the growth status of BlackBerry seedlings to determine the amount of fertilizer, mainly topdressing phosphorus and potassium fertilizer, if the BlackBerry growth is not very good, more nitrogen fertilizer, topdressing generally choose quick-acting fertilizer, topdressing about 3 times a year. The first topdressing was carried out when the sprouting branches occurred after sprouting, mainly applying nitrogen fertilizer to meet the nutrients needed by the BlackBerry seedlings at the flowering stage and promote the better growth of the sprouting branches; when the BlackBerry seedlings were enlarged after setting the fruit, the second topdressing was carried out, generally applying nitrogen and phosphorus fertilizer or compound fertilizer to promote fruit development and annual branch growth. After the fruit is ripe, the third fertilization is carried out to increase the accumulation of nutrients in the tree, improve the cold resistance of the BlackBerry tree in winter, and lay a good foundation for the high yield of the following year. The method of ditch or hole application can be adopted when topdressing, and the soil should be covered after fertilizer is applied. And proper watering.

6. Pruning

Set up a fence-shaped support in the garden, and in the year of planting, set up a pillar about 2.5cm in length along every 5-6cm of the planting row. The pillar should be buried in the ground of 60-70cm, the ground height is about 1.8m-1.9m, and 2-3 wires are tied to the pillar.

In early summer, when the height of the sprouting branch reached 1-1.5cm, the seedlings were cored to promote the growth and development of lateral branches; after picking the fruit from July to August, the dead branches of the fruit trees were removed, the sprouting branches of the previous year were removed from the roots, and the lateral branches on the sprouting branches were carefully cut off to reduce the damage to the branches of the same year, and the dead branches should be cleared out of the BlackBerry orchard in time.

7. Disease control

In order to promote the better growth of BlackBerry, improve the ecological environment in BlackBerry garden and strengthen cultivation management, we should pay attention to the prevention and control of natural enemies and make full use of the natural control effect of natural enemies in planting BlackBerry. We can choose efficient biological agents and chemical pesticides of Didu for control, and we should also pay attention to the rotational use of drugs in order to reduce the amount of pesticides and reduce the impact on BlackBerry quality and pesticide residues.

Pests such as ground tiger, red caterpillar and beetle will have a certain impact on BlackBerry. in the process of planting, we should master the occurrence law of land tiger and other pests, use poison bait to trap them, and take measures to trap them by using their phototaxis. We can also use efficient and low-toxic pesticides to prevent pests such as caterpillars and moths. In the process of planting, we should grasp the occurrence rules of pests and prevent them as soon as possible to reduce losses.
