Artificial cultivation of raspberry

At present, the cultivated raspberry varieties are mainly selected from wild raspberry, with a yield of 320kg per mu, a high yield of more than 500kg and an output value of more than 3500 yuan per mu. The cultivation techniques are as follows:

Soil selection: raspberry has a wide adaptability, but it is better to plant on sandy loam with good permeability and avoid stagnant water. Planting time: the Beginning of Winter and before and after sting. If the branches are transplanted in winter, there will be a small amount of fruit the following year. Planting density: it should be determined according to soil fertility and management level, and those with good fertility and high management level can be sparsely planted properly, otherwise they should be planted densely. Generally, 500 plants are planted in 300 Mu. Rational fertilization: raspberries need to be fertilized three times a year. First, winter fertilizer, mainly barnyard manure, about 1.5 tons per mu; second, flower fertilizer at the beginning of flowering of raspberries in the middle of March, with 600 kilograms of dilute cooked manure water per mu or 10 kilograms of ternary compound fertilizer; and third, strong seedling fertilizer after the end of the clear garden, applying 1.5 tons of rotten organic fertilizer per mu or 812 kilograms of ternary compound fertilizer. Core pruning: when the seedling grows to more than 160 cm in spring, remove the top at the seedling height of about 160 cm to promote branching. In general, pruning before and after the Beginning of Winter is mainly to remove branches such as over-twigs, over-dense branches and branches of diseases and insect pests, and the number of leaves should be determined according to the strength of the tree.
