Matters needing attention in plum planting

Plum is a traditional fruit variety in China, which is widely distributed in our country and is basically planted in every region. Plums and plums are also very similar, but there are still essential differences between them. Today, we are mainly here to understand some problems that need to be paid attention to in the process of plum planting. Let's take a look.

1. Selection and planting of seedlings

Now there are many varieties of plums, so when we plant them, we should choose plum seedlings that are pure, excellent, well-developed roots, full flower buds, strong and free from diseases and insect pests. When planting, it is necessary to make rational use of land resources, and control the permeability of the field. In general, the spacing between rows of each plum tree is about four meters, and the spacing between plants is 2.5 to three meters.

2. Pollination tree collocation

In order to improve the fruit setting rate and the quality of plums, it is necessary to distribute the number of pollination trees reasonably when planting. In general, it is planted according to the ratio of three to one, four to one and eight to one. In addition, the variety of plum trees planted had better be multi-variety, but a single variety is not the best planting plan. We can grow it with black amber, black gemstone, beautiful plum, American late-maturing plum, royal gemstone and so on.

3. Management of flowering and fruiting period

When plum florescence meets overcast and rainy weather, in order to prevent Rain Water from scouring pollen and affecting pollination, you can cover the crown with a film to cover the rain. Of course, you can also collect pollen for artificial pollination. In the full bloom of plums, we need to thinning flowers properly, to get rid of some stunted flowers, flowers damaged by diseases and insect pests, and flowers that grow too dense. After the fruit is set, in order to ensure the yield and quality of plums and reduce the drop of fruit, it is necessary to thinning the abnormal fruit, disease and insect fruit, dense fruit, weak fruit, etc., do not be reluctant to give up.

4. Pruning and shaping

In the process of plum tree growth, reasonable pruning should be carried out according to its age, tree potential, growth stage and plum tree varieties, not blindly pruning, otherwise it will also affect the yield and quality of plums. During the sapling period, it is necessary to cut frequently to form a complete tree shape, and at the same time to dwarf the tree body as much as possible and expand the crown. Adult plum trees need to control the tree potential, make proper cutting, thinning and cultivation of branches, so as to maintain the vitality of the tree and ensure its yield.

5. Light regulation

The effect of light on the growth of plums is also very great, in the process of fruit tree growth, we should reasonably control the distance between branches, which can enhance the ventilation and light transmittance of the crown. The second is in the summer, to carry out appropriate shading, transmittance control at about 30%. When the sun is mild and the light intensity is weak, the transmittance can be increased appropriately, and the transmittance can reach about 60% to 80%. However, the demand for light during fruit ripening period is relatively large, which should be controlled at least above 85%.

6. Temperature and humidity management

During the growth of plum trees, the management of temperature and humidity is very important. In the flowering period of plum trees, it is best to control the temperature at 20 to 25 degrees, which is conducive to the spread of pollen. In the process of fruit growth and development, there are no strict requirements for temperature, as long as the lowest temperature is not less than ten degrees. Finally, the humidity of plum growth and development period is generally about 50%, the humidity of flowering period is 60%, and the humidity of fruit growth period is between 40% and 50.

When planting plums, in addition to the above-mentioned points, we also need to pay attention to the rational use of medicine and scientific fertilization, which have a great impact on the yield and quality of plums. If you have any other questions to consult, remember to leave a message below.
