High-yield cultivation and management of planting raspberry

Raspberry is very adaptable and can be planted in most areas outside the Qinghai-Tibet Plateau in China. Raspberry can endure a low temperature of-40 ℃ and 45 ℃ in the north, and can be planted anywhere in the south. Some changes will take place in the subtropics because the roots of raspberries do not have natural dormancy and will grow year-round without falling leaves when their symbiotic conditions are met. The fruit can be picked twice a year, but the fruit type is slightly smaller than that in the north, and the yield is higher than that in the north. There are many varieties of raspberries, with more than 400 species in the world. From the fruit shape, there are red, black, yellow, purple and other colors. The weight of the fruit is generally 10 grams at 5 Mel, and the maximum is up to 20 grams. The output of raspberries is 1000, 000, 500 kilograms per 667 square meters.

Gardening and planting

Raspberry can be planted in spring and autumn. It is better to plant raspberry in spring before seedling germination after soil thawing (March-April) and in autumn after seedling texturization to before soil freezing (October-November). Raspberry field planting row spacing 2.5 meters, plant spacing 0.8 meters, 2-3 plants per hole, 667 square meters 660-990 plants. Soak the roots of the seedlings for 12-24 hours before planting to ensure that there is enough water in the seedlings. When planting, the root of the seedling is 15 cm from the ground and 30 cm around the seedling. When covering the soil, the soil should be compacted, and the soil should not exceed the imprint of the seedlings. Pour water thoroughly at one time.

Set up a frame to introduce branches

When the branch grows to 1.5 meters, it must be put up to introduce the branch. Set up a column at a distance of 5Mel 10 meters in the line, 1.5 meters high, and pull two wire wires. The upper wire is fixed at the top of the pillar, and the lower wire is 1 meter from the ground. Fan the branches to the wire and tie it up.

Pruning

Pruning is divided into three times, the first pruning is at the time of planting, after the seedlings survive, the thin and weak branches and damaged branches should be cut off. When the new shoot grows to 40ml / 60cm in the same year, the plants with lower density can be coring for 10cm to promote the germination of new lateral branches and increase the number of branches. The second time is the pruning of basal branches (that is, new shoots of the current year). It is appropriate to keep the basal branch shears at 1.3-1.5 meters, and prune more than 1.5 meters. 8 strong basal branches are selected for each clump, and the rest are cut off. The third pruning is when the fruit-bearing mother branch is cut off at the end of the harvest.

Fertilizer and water management

Base fertilizer should be in early autumn, mainly rotten farm manure, or an appropriate amount of chemical fertilizer can be added. The base fertilizer was 40 cm away from the plant and mixed with the soil on one side. When applying chemical fertilizer, the soil should have sufficient moisture, and about 0.5 kg of compound fertilizer should be applied on the side 50 cm away from the plant. Raspberries are root plants. Drought watering, the soil moisture can reach 40 cm, the original is drought can be irrigated, waterlogging can discharge. Pour frozen water once before the weak side enters winter. In arid areas, some leaves and broken straw can be covered around raspberries, which can prevent water evaporation and increase soil fertility.

Intermediate ploughing and weeding

Raspberry weeding can be carried out twice a year, chemical weeding can use alachlor, glyphosate, simazine, Liguron and other chemical weeding (according to the instructions). In order to improve the utilization rate of land, we can plant some dwarf plants in fruit trees, such as legumes, potatoes and so on.

Raspberry fruit can be picked and listed in well-done, and industrial deep processing must be fully ripe before it can be harvested.
