Detailed Explanation of Key Points in Plum Tree Planting and Management Techniques
Plum belongs to the Rosaceae family, Prunus genus. Its appearance is crystal clear and translucent, with a sweet and sour taste, and it is loved by many people. Plums help promote the secretion of gastric acid and gastric digestive enzymes, and surveys show that plums contain an astonishing amount of antioxidants, and are known as a “super fruit” for anti-aging and disease prevention. Today, the editor brings you the management methods for plums, let's take a look together.
1. Planting Method
Plum trees are generally planted starting in spring, because plums are prone to frost damage in autumn and winter. After selecting a site and building the orchard, dig planting holes. The planting holes are generally 1-1.2 m deep, with a diameter of 0.8-1 m. When digging the holes, the excavated soil must not be transported outside the orchard; it should be placed around the holes for later use. Then place the plum sapling vertically in the hole, being careful not to let the roots tangle together, and spread all the roots out, because this helps the roots grow comprehensively and absorb nutrients. When filling with soil, shake the trunk while filling so that all of the trunk comes into full contact with the soil. When the fill reaches 20-30 cm, mix fertilizer with the soil and continue filling. When the fill reaches 50-70 cm, tamp the soil while filling, and finally leave it 10-20 cm above the ground. Water immediately after filling with soil.
2. Soil and Fertilizer Management
Plum trees have very low requirements for soil; no matter what kind of soil it is, they can quickly adapt and grow normally, and there are no particular requirements for pH. However, deep soil layers and fertile soil can promote the growth and development of plum trees, and some vegetable crops can also be planted between each tree. But if the soil is relatively poor and shallow, some beans such as broad beans can be planted. Of course, these are not planted for your own consumption, but are turned into the soil as fertilizer for the trees around the Beginning of Spring the following year.
3. Fertilization Timing
(1) Post-harvest fertilizer: Post-harvest fertilizer is mainly applied after harvesting the fruit in summer. This stage is when plums need fertilizer the most. The main fertilizers used can be farmyard manure and green manure. The purpose is to restore the nutrients lost by the tree after harvest and prevent premature leaf drop.
(2) Pre-flowering fertilizer: Pre-flowering fertilizer is applied in spring when the flower buds begin to sprout. The amount of fertilizer needed is the least, and quick-acting nitrogen fertilizer is mainly applied. The purpose is to promote flowering.
(3) Fruit-swelling fertilizer: Fruit-swelling fertilizer is applied when the fruit begins to form a stone, with the purpose of promoting fruit enlargement and providing sufficient nutrients. Compost is mainly applied, and the fertilizer requirement is second only to the post-harvest period.
The above is a brief summary by the editor of the matters needing attention before and after planting plums. Plums are actually very easy to grow, and their soil requirements are not strict at all, unlike other fruits. The main thing is still the three fertilizations during the growth period. These three fertilizations are related to the final yield and quality of the plums. Of course, plum trees also have many diseases that need to be prevented and treated.
