Plum tree, also known as cherry plum, is a common fruit tree. Because the fruit is exquisite and fruity, the taste is sweet and sour, and it is rich in nutrients. It is popular among people and is rich in nutrients such as protein, fat, vitamins, calcium, phosphorus and iron. It can improve appetite, promote digestion, nourish beauty, and lubricate the skin. Therefore, the market demand for plums is also very high. It is also good to grow plums. How to fertilize high-yield plum trees? Let's go check it out!
1, base fertilizer
The general base fertilizer is able to supply the long-term nutrients of plum trees, mainly based on late-effect farmyard manure. Compost, manure, crop straw, green manure, and fallen leaves can all be used as fertilizers. An appropriate amount of quick-acting nitrogen fertilizer can be added to the base fertilizer, and these fertilizers can well satisfy the large amount of nitrogen required for the early spring germination and flowering of plum trees. In addition, it is recommended that growers apply base fertilizer in autumn, because the ground temperature in autumn is high, and the base fertilizer after application can be decomposed as soon as possible, which will not cause excessive damage to the roots of the plants. Of course, it can also directly apply decomposed farmyard manure.
2. Topdressing: According to the characteristics of the fertilizer required for each phenological period of plum trees, a certain amount of quick-acting fertilizer is applied in stages during the growing season.
Plum tree topdressing time is generally divided into the following periods:
(1) Top dressing before flowering: In order to satisfy the germination and flowering period of plum tree, a large amount of nutrients are needed, and the quick-acting nitrogen fertilizer can be applied about 10 days before the germination of plum tree.
(2) Post-flowering topdressing: At this time, the young fruit and the new shoots enter the peak of growth at the same time. In order to avoid competing with each other, the quick-acting nitrogen, phosphorus and potassium fertilizers should be applied in time to reduce the physiological fruit drop and increase the fruit setting rate. Promote the simultaneous growth of young fruit and new shoots.
(3) Fruit swelling and flower bud differentiation period: After the physiological fruit drop to the fruit into the rapid expansion period, the application of available nitrogen, phosphorus and potassium fertilizer can greatly improve the photosynthesis efficiency and promote the accumulation of nutrients in the tree, which is beneficial to the fruit. Inflated, it is also conducive to the differentiation of flower buds.
(4) Topdressing in the late stage of fruit growth: topdressing during the beginning of fruit coloring to harvesting. This time, phosphorus and potassium fertilizers are the main factors, and quick-acting nitrogen fertilizer combined with spraying is good for foliar spray fertilizer, so as not to promote the growth of the tree after the autumn and affect the nutrient accumulation of the tree. This time, the fertilizer is extremely important for tree growth, high yield and stable yield, fruit quality and annual yield.
In summary, if a farmer friend wants to plant a high-yield plum tree, it is best to master the professional fertilization techniques and management methods. I hope this article will help everyone.
