High-yield planting techniques of black pearl cherries!

Black pearl cherry is a kind of excellent cherry which has been cultivated by Chinese cherry. The fruit is beautiful in shape and purplish red in color. It is a high-grade fruit in the market. The selling price is higher than ordinary fruit and it has good commodity value. Here are some high-yield planting techniques of black pearl cherry!

I. Garden site selection

Black pearl cherry likes light, is not resistant to waterlogging and drought, so it is suitable to choose sloping land with good light, which is conducive to drainage and deeper soil layer to build a garden, and the sandy loam soil with a pH value of 6: 7 is the best. If the garden is built on flat land or clay land, attention should be paid to trench drainage and soil improvement. One month before planting, the trenches of 80~100cm and deep 60~80cm can be opened according to the planting row, and the soil can be pressed layer by layer, such as miscellaneous leather, crop straw, phosphate fertilizer, pig manure water, etc. It can also be planted according to the designed density, and then enlarge the hole and improve the soil year by year.

II. Seedling colonization

It can be planted from September to February of the following year, but it is the best in the Xiaoyang spring climate from October to November. By dwarfing and dense planting, the row spacing is 1.5x3.0m (150trees per mu), and the self-flowering rate of black pearl cherry is high, but it is not suitable for pollination trees. but in order to obtain more reliable yield, pollination trees can be planted at 1:8. At present, Dahongpao cherry is the main pollination variety, and the root should be well watered and watered thoroughly. After it has all infiltrated, sprinkle a layer of fine niobium soil on the tree plate, and finally cover the tree plate (thick 2~5cm) less than 1.0m in diameter with weeds to maintain soil moisture.

Third, shaping and pruning

During the period of young trees, summer pruning is mainly used to pick the heart and pull branches from strong branches in summer to promote branches to form medium and short branches, mainly in winter pruning, and more to promote bouquet-like fruiting branches. On the other hand, high-yield trees mainly use winter pruning and retraction to improve the lighting and ventilation conditions of trees, so that they are not sparse on the outside and inside, and have three-dimensional results, renew the weak branches, retract the senile branches, and at the same time retract to the branches between the rows, so as to maintain the ventilated and transparent zone around the 80cm between the rows, properly retain the internal long branches according to the situation, twist and coring in summer, and cultivate them into new branches. in addition, cherry buds are solitary. In short pruning, leave leaf buds as cutting buds.

IV. Fertilizer and water management

Young black pearl cherry trees grow fast and are easy to flower. In order to produce early and high yield, the management of fertilizer and water should be strengthened in the year of planting, so that it can quickly form a high-yield crown, and stop growing before July, so as to complete flower bud differentiation as soon as possible. When the dense planting garden enters the high-yield period in the third year, the amount of nitrogen fertilizer should be properly controlled and phosphorus and potassium fertilizer should be increased. The orchard is ploughed once a year in winter, the interrow weeds are weeded with herbicides 2 or 3 times a year from March to October, and the tree plates and rows are covered with weeds or crop straw from March to April. Proper irrigation should be given during 5 consecutive days of drought to keep the soil moist to reduce fruit cracking.

The above is the introduction of the high-yield planting techniques of black pearl cherries by Tuliu. in the process of planting, we should also pay attention to the prevention and control of diseases and insect pests. The main diseases of black pearl cherries are leaf spot, perforation, dry blight, brown rot and so on; pests are mainly pear heart borer, peach tumor aphid, mulberry white scale, boat caterpillar, etc., and pesticides such as pyrethroid, imidacloprid, quick culling and scavenging can be used respectively.
