How to raise the latest potted fruit trees?

Fruit trees are dwarfed as pot cultivation has been favored by many people, but fruit trees are always fruit trees, and their roots will be restricted to a large extent because of the limited volume of the container. therefore, it is necessary to make the limited potted soil much more fertile than the natural soil in order to maintain the normal life activities of pot planting. Let's take a look at how to raise potted fruit trees.

Flowerpot selection

The flowerpots of potted fruit trees should choose tile pots, buckets and wooden boxes with good ventilation, good root growth and low price, which are mainly round in shape. among all kinds of texture containers, plain tile pots are the most suitable for planting fruit trees. The size of the flowerpot can be determined according to the needs, the general indoor or balcony display can choose the inner caliber of 25 cm 45 cm, 20 cm high about 35 cm.

Basin soil allocation

1. 6 parts of fertile ripe soil, 2 parts of river sand, 1 part of rotten sheep dung, 1 part of retting leaves and horseshoe fermentative fertilizer, mixed evenly according to proportion and sifted.

2. 5 parts of compost soil, 2.5 parts of garden soil and 2.5 parts of sandy soil, and then add 0.5 kilogram of 25% kryptonite compound fertilizer per cubic meter and mix well.

3. 4 parts of garden soil, 3 parts of humus soil, 2 parts of fine yarn soil and 1 part of plant ash were fully mixed and screened.

Pot culture

Select seedlings with strong plants, full bud eyes and no diseases and insect pests to be planted in pots before sprouting in spring. Before planting, root pruning, necrotic roots, and injured lateral roots should be trimmed, excessively long lateral roots should be cut short to promote their growth into fibrous roots, useful fibrous roots should be retained as far as possible, and overlong fibrous roots should be cut to about 20 cm, and disinfected by soaking them with 5-degree stone sulfur mixture. When planting, put a few pieces of broken tiles on the hole at the bottom of the basin, put a layer of coarse sand, add some nutritious soil, put into the seedlings, put the root system evenly, add enough nutritious soil to compact, pour enough water, and cover with plastic film.

Fertilizer and water management

As the root growth of potted fruit trees is limited, the nutrients absorbed by potted fruit trees are far from enough to meet the growth needs of fruit trees, so special attention should be paid to fertilizer and water management. Fertilization should be based on organic fertilizer, supplemented by available fertilizer, in line with the principle of less application for many times, combined with extra-root topdressing. In general, diluted organic fertilizer solution is applied every 7 to 10 days or so, urea solution can also be applied alternately with organic fertilizer liquid for 2 or 3 times in the early stage, and a small amount of nitrogen and potassium compound fertilizer can be applied on the basin soil in the last fertilization in September. 0.3% potassium dihydrogen phosphate plus 0.3% urea is used for extra-root topdressing to ensure nutritional supply. Potted fruit trees should maintain a certain humidity of the potted soil during the growing period, and should be watered in time after drying, but it should not be too wet. Water once in the morning and evening in summer and every other day in autumn. watering should be strictly controlled during the dormant period, with the basin soil but dry.
