How to cultivate raspberries artificially? A detailed explanation of the key cultivation techniques

The raspberry varieties currently cultivated are mainly domesticated varieties bred from wild raspberries, with an average yield of 320 kg per mu, and high yields of more than 500 kg, and a output value of more than 3,500 yuan per mu. The cultivation techniques are as follows:

Soil selection: Raspberries are widely adaptable, but it is best to plant them in sandy loam with good permeability, and waterlogging should be avoided. Planting time: Both around the Start of Winter and around the Awakening of Insects are suitable. When transplanted in winter with branches, a small amount of fruit will be produced the following year. Planting density: This should be determined according to soil fertility and management level. If fertility is good and the management level is high, planting may be appropriately sparse; otherwise, it should be appropriately dense. Generally, 300-500 plants are planted per mu. Rational fertilization: Raspberries need to be fertilized 3 times each year. The first is winter fertilizer, mainly barnyard manure, applied at about 1.5 tons per mu; the second is flower fertilizer at the beginning of flowering in mid-March, applying 600-800 kg of diluted decomposed manure water per mu or 10-15 kg of ternary compound fertilizer; the third is seedling-strengthening fertilizer after orchard cleaning is completed, applying 1-1.5 tons of decomposed organic fertilizer or 8-12 kg of ternary compound fertilizer per mu. Pinching and pruning: In spring, when the seedlings grow to more than 160 cm, pinch them by removing the top at about 160 cm in height to promote branching. Pruning is generally carried out around the Start of Winter, mainly removing overly thin branches, overly dense branches, and diseased and pest-damaged branches. The number of branches retained should be determined according to the vigor of the tree; retain more when the tree is vigorous and fewer when it is weak.
