How big a pit to plant cherry trees

The width and depth of the pit for planting cherry trees can be controlled at 30 centimeters and 30 centimeters, because the root system of cherry trees is relatively small, so most growers choose annual cherry seedlings for planting. Fertilizer should be applied at the bottom of the pit before planting, and the seedlings should be watered thoroughly once after planting. After the seedlings sprout, the principle of watering should be followed as soon as they are dry. In order to make cherries grow better, they should generally be watered with thin fertile water once or twice.

The root system of cherry trees is not very large. Nowadays, most people choose to plant annual cherry saplings. The pit of cherry trees is 30 centimeters wide and 30 centimeters deep. Before planting, some phosphorus and potassium fertilizer and stable fertilizer should be applied at the bottom of the pit. After planting, the seedlings should be watered thoroughly. After the seedlings germinate and survive, they can be irrigated in accordance with the principle of watering as soon as they are dry. Generally, they should be watered with thin fertilizer once or twice to promote the growth and fruiting of cherries.

1. Suitable temperature

The temperature of big cherry should be controlled at about 10 ℃ during germination and above 15 ℃ during flowering. When the temperature is above 20 ℃, the growth rate of new shoots is the fastest. When the temperature is 20-25 ℃, it only takes about 50-60 days for fruit to mature. Big cherries are afraid of cold and frost. In order to make them grow normally, they should be protected from frost in early spring and winter.

2. Soil requirements

Planting big cherry is best to choose the soil with deep soil layer, soft soil and good ventilation. Many varieties of cherry seedlings require higher soil acidity and alkalinity, and the soil pH value had better be neutral.

3. Moisture requirement

When planting big cherries, it is necessary to ensure sufficient water, especially the root system of the seedlings, and strictly control the moisture. Too high moisture will make the branches and leaves of the big cherry seedlings flourish, but it will affect the root respiration and lead to root ulceration; too low moisture, due to the root system can not absorb enough water to lead to early senescence, which will affect the yield.

4. Lighting requirements

The growth, fruit setting rate, fruit ripening time and quality of cherry trees are related to light to a certain extent. Only with sufficient sunshine can big cherry trees grow normally, and the fruit setting rate will be increased, and the fruit ripening time will be accelerated to a certain extent. and the sugar content in the fruit will be higher, if the light is insufficient, it will make the periphery of the crown grow, the life span of tree branches will be reduced, and the yield and quality of fruit trees will be affected.

5. Daily disease control

The common pests of cherry trees are mulberry scale, stinging moth, beetle, pear heart borer, cherry leaf spot, bacterial perforation and so on. Traditional Chinese medicine should be more prevented in the planting process, generally pruning in summer, cutting off and burning the branches in time, and spraying Baume 5-degree stone sulfur mixture once in the defoliation period. before the spring shoot leaves stop growing, spray 1200 times of dimethoate and 1200 times of methyl topiramate. You can spray 50% marathon emulsion 1000 times and 65% Dyson zinc 400 times 500 times in July and August.
