Detailed instructions on planting methods:

Selection of containers: The containers for big cherry cultivation have good air permeability and no toxic effect on the root system. The best effects are burning pots and wooden barrels, followed by purple sand pots and plastic pots, and enamel pots are the worst, because big cherries are not easy to survive after being put into pots.

Soil preparation: the root system of big cherry has strong respiration and large oxygen consumption. Soil requires high permeability, especially sandy loam with loose soil and deep soil layer. The ratio of nutrient soil is peat soil: manure: sand =5:3:2.

Selection of seedlings: the seedlings of big cherry should choose trees with strong growth, full branches and buds, developed roots and no pests and diseases. Small perennial trees should be short, with reasonable branch distribution and large taper between branches.

Upstream basin:

Time: The time for big cherries to cook is mostly in early spring. Trim the damaged roots and branches to expose new stubble and cut off the parts with pests and diseases before serving in the basin. Secondly, check the drain hole of the container to keep the container drained smoothly.

Methods: Put a tile upside down on the drainage hole, then spread a layer of furnace ash and slag about 20 cm, put in nutrient soil, and finally put in seedlings. After 2 ~ 3 times of raising seedlings and pressing soil, the soil surface is about 5 cm away from the mouth of the container.

Fertilization: Big cherry should be watered frequently when there are many branches and leaves and the temperature is high, otherwise the soil will be too dry, which will affect its growth, flowering and fruiting. Fertilization should master the principle of applying thin fertilizer frequently. From spring to autumn, it is generally required to apply decomposed rapeseed cake fertilizer every 10 ~ 15 days. In autumn, 0.5% potassium dihydrogen phosphate aqueous solution should be sprayed 2 ~ 3 times to promote plant growth and flower bud differentiation.

Heat preservation and moisture retention: Big cherries are cold-resistant, and plastic film greenhouses can be used for cold protection in cold regions. Keeping the temperature at about 25℃ during the fruit-setting period and the humidity at 50% ~ 60% during the growth period is beneficial to flower bud differentiation and increase the yield. If there is freezing injury in the local area, potted cherries must be kept warm and moist.

Flower and fruit management: The flower and fruit thinning of big cherry is the key point of flower and fruit management, and bud thinning is stronger than flower thinning, and flower thinning is stronger than fruit thinning. There are a large number of flower buds in the tree, and some flower buds are thinned out in bud stage. The operation method is that the flower buds of 1/3 ~ 1/4 are neglected on the cluster-like fruiting branches, and cross-pollination is carried out at the flowering stage. When the fruit grows to the size of soybean, the heteromorphic fruit is neglected.

Pruning: the terminal bud of big cherry and the central bud of the flower cluster are leaf buds. Flower buds are pure flower buds, mainly axillary buds and bouquets. Axillary buds are usually planted at the base of 1 annual branches, and attention should be paid to the position of flower buds when pruning. Pruning is mainly in summer, supplemented by pruning in winter.
