More and more people are planting raspberries, so do you know the potted method of raspberries? The following is the planting method of potted raspberries that I carefully arranged for you. Let's have a look.

Planting method of potted raspberry

Basin selection:

Choose 35~40cm flowerpots, clay pots and wooden barrels, but there should be leakage holes at the bottom.

Preparation of basin soil;

Restricted by containers, potted raspberries should choose soil with rich and loose soil, good water and fertilizer conservation performance and good ventilation performance, and the ideal soil is natural humus soil.

Plastic decoration:

After the seedlings are put into the pot, stubble can be removed at a height of 3~5cm. When the new branch grows to 20 cm, the top of the branch can be removed (enucleated) to promote the germination of new lateral branches. When the lateral branches grow to 20 cm, they can be cored repeatedly until autumn, and they can blossom and bear fruit in the next year.

Watering:

The temperature is low in spring, so watering should not be too much, and it is advisable to do it once every 2~3 days. In summer, when the temperature is high and the transpiration is large, the watering frequency can be increased and the ground can be sprayed with water to cool down; Reduce watering times in autumn. It is advisable to water thoroughly without exudation every time.

Fertilization:

The nutrition of potted raspberries is supplemented by topdressing. Fertilizer can be fermented with water and combined with watering. It is wise to apply less fertilizer and more fertilizer.

Overwintering management:

Overwintering dormancy, potted raspberries, 165438+ 10 raspberries begin to hibernate after defoliation, and the ideal place is outdoor vegetable cellar. If there is no vegetable cellar, it can be placed in cold places such as corridors and basements. The temperature must be controlled at 5c? ~-5c？ Suddenly, if the temperature is too high, it will germinate in advance, and if it is too low, it will freeze raspberries. Regularly check the humidity, that is, control the watering, but also maintain a certain humidity of the basin soil, so as to avoid neglecting watering and dying of thirst when sleeping. In addition, potted raspberries have another feature. If the winter management conditions are good and the temperature and humidity reach the growth conditions of raspberries, raspberries will not shed leaves and continue to grow.

Scientific cultivation method of raspberry

Before planting, the roots of seedlings should be soaked in water 12-24 hours to make the roots absorb enough water and improve the survival rate. The requirement of planting is deep planting and shallow burial. Deep planting means that the roots of the seedlings are off the ground 10- 15 cm, and shallow burial means that the soil should not exceed the original soil marks of the seedlings within 30 cm around the seedlings. Deep planting is because the new roots move up year by year with the growth of tree age, while the roots below will age year by year. In order to ensure the normal growth of trees, deep planting should be carried out. The purpose of shallow burial is mainly to shorten the slow seedling stage and improve the survival rate.

After raspberry is planted in spring, it usually takes 1-2 months to extract the basic branches, because the nutritional center of the plant is in the underground roots, not on the ground. This is the particularity that raspberries are different from other kinds of fruit trees, so it is appropriate to investigate the survival rate of raspberries for 2 months after planting. After planting in autumn, the roots of raspberries have resumed growing before the soil is frozen, but some buds on the ground go into dormancy and do not germinate, which not only improves the survival rate, but also lays a good foundation for the rapid growth in the next year, so the survival rate of raspberries planted in autumn is higher than that planted in spring.

Key points of raspberry planting

Carry out soil preparation

The best soil preparation method for raspberry orchard is comprehensive mechanical soil preparation, and the soil preparation time should be carried out half a year before planting.

Fertilizer management

According to the soil conditions in the planting area. Generally, organic fertilizers are mainly applied, such as manure, compost, oil cake, peat and other solid fertilizers, which are not easy to lose. Spraying Zhuhuawang No.2 at the flower bud differentiation stage can promote the formation of flower-forming genes, and spraying Zhuangguodiling at the young fruit stage can thicken the fruit pedicel and increase nutrient transport.

water management

Raspberry root system is very shallow, so it is not easy to absorb deep soil moisture. Therefore, root water should be poured in time after planting, so that the young roots can be closely combined with the soil, and the roots begin to sprout and grow to fix the young trees. When the flowers bear fruit, the water consumption is even greater, and the growing water needs to be irrigated. After defoliation in winter, seedlings should be watered with frozen water before burying soil in winter to prevent cold and improve the wintering ability of trees.

Pruning and scaffolding

Pruning is mainly aimed at the first-class stems and flower stems, thinning some branches and improving the nutritional space of the population. Scaffolding can reduce the interference of primary stems, improve illumination and increase yield. It is necessary to put a healing antiseptic film on the trimming mouth to promote wound healing.

Overwintering protection

In areas where the temperature is below -35℃ in winter, cold protection measures should be taken. Generally, it is carried out after several first frosts and before the soil freezes. Coat the tree with a tree protector to protect it from overwintering.
