First, planting raspberries can be planted in spring and autumn. Planting methods include single planting and strip planting. The plant spacing of each plant line is 2 meters, and the band planting is suitable for large-scale planting with a spacing of 2.5 meters, a plant spacing of 0.3 meters, and 330 planting holes per acre. Before planting, the roots of the seedlings should be soaked in water for 12-24 hours. They must be planted and buried in shallow depths. The roots of the seedlings should be 10-15 cm from the ground when they are deeply planted; shallow burial is not to exceed the depth of 30 cm around the seedlings. The original seals on the branches. The scaffolding is one of the important measures for the high yield of tree seedlings. A pillar is erected every 5 to 10 meters in the row, 1.2 to 1.5 meters high, and two iron wires are pulled. The upper iron wire is fixed on the top of the pillar and the lower iron wire is 1 meter away from the ground. The scallops can be attached to the wire. Second, pruning The first time pruning is carried out in the early spring to plant pruning, and the dense and weak branches and broken branches must be cut off. When the new shoots grow to 40-60 centimeters in length, the 10 centimeters can be picked up for the less dense plants. The second trim is the pruning of the basal branches (ie, the new shoots of the year). The basal branches remain within 1.3-1.5 meters. Each year, 6-8 strains of strong basal branches are selected for each strain, and the rest are cut off. The third trimming is after the harvest is completed, the result of the mother tree must be removed. Third, the fertilizer and water management Shiji Fei should be in the early autumn to maturity farmyard fertilizer, but also can add appropriate amount of chemical fertilizers, such as urea, ammonium phosphate and so on. When fertilizing, fertilize on the side of 40-60 cm from the plant, about 0.7 kg of fertilization per plant. Mix the basal fertilizer with the soil and change to the other side of the plant during the second year of fertilization. Top dressing was divided into 2 parts. The first topdressing was in flowering to young fruit formation stage. Nitrogen fertilizer was the main fertilizer. The second topdressing fertilizer was in the late fruit harvest stage. The topdressing fertilizer was mainly phosphorus and potassium fertilizer, and the average fertilizer was 50 per plant. g, topdressing fertilizer on the side of the plant 50 cm, it is best to cover a thin layer of soil. In areas where dry and dry rain is not suitable for top dressing, fertilizers can be sprayed on branches or leaves for extra-root fertilizer. Fourth, winter cold winter temperatures below -35 °C area, should take cold measures. The cold-proof time should not be too early, generally in the early winter after several early frosts, before the soil is completely frozen. When burying in the cold, first cut the raspberry basal branches as required, and push them straight down in one direction along the row. Stack the pillow soil at the bends of the twigs to prevent heavy pressure after the burial. When the soil is buried, it must be photographed in order to prevent wind penetration. Take the soil 1 meter away from the plants to prevent root damage. When spring soil withdraw time is generally stable at 3°C-5°C when the ground temperature is 10cm, it is necessary to withdraw the soil on both sides and then remove the soil on the soil so as not to bump the shoots. After the soil is removed, the branches shall be tied to the wire in time. V. Breeding Techniques (1) The ramie method The red raspberry has a large number of root litchis every summer. When it grows to 1-1.3 meters, it will be picked up to promote the development of the root system. By the autumn, it will develop into a separate new seedling. (2) Cuttage The annual sticks of 40 centimeters are clipped in autumn and stored in the cellar. In the early spring, the two ends of the shoots were inserted into a 1-meter-wide crucible at a spacing of 20 cm, with two per cut. The cuttings are bowed. After the new shoots are rooted, the shoots are cut from them and they become 2 seedlings. (3) Bracting method The ability of blackberry to grow root lychee is weak, but it has the characteristics of the primordial branch to touch the roots. Therefore, blackberry breeding can use this method or cutting method. When the batten is punched, a shallow ditch is dug along the extension direction of the basal branches so that the entire twig is bent in the ditch and fixed. When the new root shoots below the root, gently press the soil, do not cover the leaves, and in the fall, separate from the mother plant to become several new plants.
