Cultivation techniques of black raspberry

Black raspberry, also known as purple raspberry, is a common fruit in hillsides and wet places under the forest. It has the laudatory name of "fruit of life". It has high nutritional value, and many people like to pick and eat it. At present, most areas are planted. What are the cultivation techniques of black raspberry?

1. Land selection and preparation

Black raspberry has high requirements for soil, and it is suitable to grow in the environment of deep soil layer, good drainage and irrigation and rich organic matter, so try to choose the soil rich in organic matter to plant. After selecting the land, it is necessary to turn the soil 25cm or so deeply and apply enough mature farm manure.

2. Colonization

(1) planting time: early spring.

(2) planting method: select some robust black raspberry plants, plant them in the cave at a distance of 2 to 1.5 meters, and finally cover the soil and pour enough water to fix the roots.

3. Post-planting management techniques.

(1) Water requirements: black raspberries do not have high requirements for water, generally as long as the soil is moist, so in the middle of June, more watering can be appropriate when there is little precipitation, and the rest of the time, the amount of watering can be determined according to soil moisture and plant growth.

(2) Fertilizer requirements: raspberry has high requirements for fertilizer, generally apply more available nitrogen fertilizer in the growing period, apply more nitrogen fertilizer before flowering and fruiting period, and properly apply phosphorus and potassium fertilizer to ensure balanced nutrition. If the soil nitrogen is sufficient, it should be dominated by phosphorus and potassium fertilizer, otherwise it should be dominated by nitrogen fertilizer.

(3) bracket: black raspberries grow vines after growing for a certain period of time. At this time, it is necessary to build some supports in the orchard. It is best to build a pillar every 5 meters.

(4) coring: when the branch grows to about 1.2 meters, it is necessary to pick the heart in time to promote the growth of lateral branches of the plant.

(5) pruning and shaping: when black raspberries grow too dense, dense branches, miscellaneous branches, diseased branches and other branches that are not conducive to plant growth should be cut off, generally at least three times a year to ensure the healthy growth of blackberries.
