According to the growth habits, plots are selected, and idle plots such as Tiantougou and barren slopes can be planted. Apply 4000 kg of decomposed farmyard manure per mu, turn over the ground and rake carefully.
Second, colonization.
It can be planted in spring, summer and autumn, and the survival rate in autumn before defoliation is high. Cultivation methods include strip method and single plant method. Fill the fine soil and tamp it, and water it. Before planting, the seedlings can be cut into short piles of 15*20 cm to reduce the evaporation surface and stimulate the emergence of strong new shoots under the incision.
Third, on-site management
1. Intertillage weeding: within one or two years after transplanting the surviving soil, weed 3-4 times a year, the first time 1 time is in spring when new leaves sprout, the second time is in May-June, the third time is in July-August and the fourth time is in late autumn and early winter.
2. Erect binding: Raspberry branches are soft and often droop to the ground due to the weight of the fruit, which pollutes the fruit and affects the quality and yield. The drooping branches cover each other, which makes management difficult, resulting in poor ventilation and light transmission. Scaffolding should be set up and branches tied in late April.
3. Topdressing: After germination in early spring and in young fruit period, intertillage weeding and topdressing should be combined. Apply decomposed human and animal manure or nitrogen fertilizers such as ammonium sulfate and urea in spring, summer and autumn. Apply decomposed fertilizer or compost, fire ash, etc. In winter. The method is to ditch between rows to a depth of about 20 cm, and then cover the soil.
4. Trimming and shaping: spring cutting, summer cutting and autumn cutting. Spring scissors combined with scaffolding to tie branches. Cut off the thin and dry part at the top to promote the germination of strong fruiting branches from the lower lateral buds. At the same time, cut off the broken branches, over-dense branches and diseased branches at the base, and keep 7-9 thick branches. Cut off the dead branches, diseased branches and weak branches, and the sparse branches will grow too densely, which will affect the dense branches with ventilation and light transmission, reduce unnecessary nutrient consumption and improve the fruit yield in the coming year.
5. Drainage and irrigation: In case of dry weather or excessive rain, a large number of flowers and fruits fall, drainage and irrigation should be done in time.
Fourth, harvesting and processing.
The fruit period of raspberries is July-165438+ 10, starting from long summer. When the raspberry fruit is fully developed and green and immature, it should be harvested in batches to remove impurities such as receptacle, stem and leaf, scalded with boiling water for 2-3 minutes, and spread out to dry. Don't pile it in rainy days, or it will be moldy and loose.
