Raspberry planting site is sandy loam with deep, slightly acidic or neutral soil layer. The p H value is 5.5-7.5. Concentrated contiguous planting in flat land or gentle slope land. Avoid building gardens in windy, low-lying and waterlogged saline-alkali land.
During the planting period, 5-7 plants can be planted in each hole in spring and autumn, with about 2000 plants per mu.
Planting method: it is advisable to dig ditches for raspberry planting, and the distance between the ditch and the center of the ditch is 2.5 meters. It is 40 cm deep and 50 cm wide, and 50 tons of high-quality farmyard manure is applied per hectare.
The planting effect in spring is better after ditching in autumn. The spacing between trees is 0.7-0.8m. When planting seedlings, plant them deep and shallow. The root system leaves the ground 10- 15 cm, and the soil is buried to the original soil mark of the seedlings.
Field management and irrigation: keep the soil moist after planting and water it in time when the soil is dry. If you encounter more problems in planting, you can consult experts on cloud breeding platform, which is the world's largest agricultural science and technology question and answer website. There are tens of thousands of planting and breeding experts, and every question raised will be answered within 2 minutes.
Fertilization, weeding and pest control: topdressing a small amount of nitrogen fertilizer (about 1.5g per plant) in the year of planting to promote the growth of new shoots, loosen soil and weed control, and pay attention to pest control.
Plant management: New shoots with a growth length of more than 50 cm and poor erectness should be tied tightly with main poles. Cover with soil to prevent cold and remove soil blockage: before winter, cover the plant with soil to prevent cold and winter, and bury the whole plant tightly to avoid ventilation.
Beginning of spring withdrew its soil in mid-April, which was too early and the humidity difference between day and night was large, which was not conducive to the germination of basic buds. In addition, the upper soil moisture is also easy to lose in the morning.
Support setting: a pillar (wood column and cement column) is set every 5- 10 meter in the line. For example, the wood column is 8-10cm thick and 2.3m long, with 1-2 iron wires pulled on it and1.3-1.5m off the ground.
In spring, the mother branches will be evenly tied to the wire, and new buds will grow that year. Results After the mother branch was drained, the new branch was tied to the iron wire as appropriate.
Pruning and shaping, fixed branch pruning: when raspberries are put on the shelves, fixed branches are pruned, and the spacing between branches bound on the fence wire is 10- 15 cm.
Picking: 2-3 times in summer and autumn. In summer, when the new shoots grow to 40-60 cm, the core is removed to promote the growth of lateral branches. In autumn, the excessive growth of new shoots should be excavated to promote the maturity of new shoots and improve their overwintering ability.
Cleaning the fruiting mother branches: thinning the fruiting mother branches, and immediately thinning the fruits after picking, so as to improve the ventilation and light transmission conditions of the long branches in the current year as soon as possible.
Pruning basic branches: Prune main branches before winter, and keep the length of 1.3- 1.8m, with an average of 6-8 branches per plant, with a maximum of 10 branches.
Fertilization, the first time from flowering to young fruit formation, is mainly nitrogen fertilizer, which promotes the vegetative growth of basic branches and fruit expansion.
The second basic branch grows vigorously for the second time, mainly phosphorus and potassium fertilizer, which is beneficial to the later growth of basic branches.
Irrigation and drainage, in terms of soil moisture, is most suitable for plant growth when the soil moisture reaches 60% to 80% of the maximum water capacity. The general water content of different soils can also be judged by manual measurement and visual inspection according to experience, which can be used as a reference index for irrigation and drainage.
