Cultivation and Management techniques of Crispy Red Plum

Crispy red plum is a common fruit on the market, it is different from other plums, its skin is thin, the fruit is crisp, the meat is sweet and resistant to storage, so it is loved by the majority of consumers. It also attracts a lot of people to plant, so how to manage the cultivation of crispy red plums? Let's get to know it with the editor.

1. Fertilization

The principle of thin application and diligent application should be adopted for young trees, from planting survival to budding, fertilizing once, applying only clear dung water and amino acid water soluble fertilizer, and then mainly available nitrogen and phosphorus fertilizer, once before germination and again after leaf expansion. Adult trees are generally fertilized three times a year, the first time from March to early April, when the root system is in the period of growth and germination, which needs to absorb nutrients, promote spring shoot growth, promote flower bud differentiation and increase fruit setting rate, so this fertilization is more important. Quick-acting nitrogen fertilizer and phosphorus-potassium compound fertilizer are mainly applied to each plant, half a jin of compound fertilizer is applied to each plant, and nitrogen fertilizer can be added properly if the tree is weak, but not if the tree is strong. In order to maintain calcium after flowering, calcium is the fourth largest element needed by fruit trees, which must be paid attention to. After fruit setting, each plant is applied 2-3 jin of high potassium compound fertilizer.

2. Tree disk cover

For adult trees, they can cover the tree plate with weeds or straw all the year round, and fertilize or expand holes to change soil into the garden in autumn, which can not only cultivate the soil, but also keep the soil moist in summer and reduce the soil temperature, which is beneficial to plant growth. It can be ploughed once in the whole garden in autumn, 10-20 cm is appropriate, combined with turning the soil to apply organic fertilizer.

3. Drainage and irrigation

In the fruit ripening period, the demand for water is low, if there is sudden heavy rain or too much rainfall, it is very easy to cause poor fruit coloring and fruit cracking, so attention should be paid to strengthening drainage yield in the rainy season. Torrential rain in summer and continuous rain in autumn are easy to cause dead trees, and the low humidity is not conducive to the growth of crispy red plum branches, so it is necessary to open ditches in time to drain water. The peak of water demand is in the fruit expansion period, when drought will affect the fruit quality and yield, but it is not suitable to water too much, so as to keep the soil moist.

4. Shaping and pruning

For the pruning of crispy red plum, different pruning methods should be adopted according to different plants and different crown shapes. For plants with exuberant growth and more flowering, the fruiting branches that have been harvested should be weak and strong; for those with closed crown, the twigs should be cut back and cut off the branches of diseases and insect pests and withered branches to increase the crown permeability. For the plants with strong growth and few blossoms, some weak branches should be thinned, and a few dense branches should be selected to shorten the cut, so as to increase the external permeability of the crown and the inner green leaf layer. For plants with weak growth and large amount of flowering, the fruiting branches that have been harvested should be cut off in time; after shortening in spring, the germinating shoots should remain strong and weak; for plants with weak growth and less flowering, the weak branches should be shortened; after shortening in spring, the germinating shoots should be weak and strong, so that the crown should be replaced with strong shoots.
