So what planting techniques do you need to master in order to increase the yield of prunes? Let's take a look at it next!
First, trim the planting skills.
1, variety selection
There are many kinds of prunes. If you want to plant prunes, you must choose a more suitable variety according to the local soil conditions and climate conditions. The variety with big and full fruit, small stone, good color, good taste and high yield is of course the best, but market factors should also be considered, such as which variety of prune is more popular. At present, the best varieties of dried plums on the market mainly include French plum, red Messi, blue honey and Stanley. Please refer to the local area for details.
2. Orchard construction
Although prune is a new fruit introduced from Europe, its planting requirements are not high. Many places in China are very suitable for planting, which is very similar to our traditional plums, and the choice of planting sites is similar.
After the address is selected, the hole should be cultivated to prevent the threat of germs and pests. Then sprinkle enough fertilizer in each hole as base fertilizer, then plant it at the interval of three meters between rows and two meters between plants, and build a garden around the fence.
3. Fertilizer and water management
After planting prunes, in addition to the base fertilizer, fertilizer is usually applied three times a year. The first time is the flowering period, you can use urea and add a small amount of potassium fertilizer to promote the flowering period. The second time, when the fruit grows, potassium fertilizer is mainly used to promote the fruit expansion. In addition, you can spray a proper amount of foliar fertilizer and apply a small amount of urea to prevent the branches from aging. The third time was after picking fruit. Compost is mainly used at this time, which can play a good role in maintaining pruning trees and better prepare for the coming year.
Step 4 trim and reshape
It is best to prune plum blossoms every year. When there are no flowers and fruits, prune some long and messy branches at the bottom of the plum, and prune some old branches at the same time, and keep the main branches of the plum growing rapidly, and then prune them after reaching a certain height, so as to grow new lateral branches and maintain a good crown and tree shape.
Mature prunes mainly prune some weak branches, dead branches, diseased branches and dense branches to ensure the yield of prunes.
5. Artificial insemination
Plum blossom can be pollinated naturally, but the phenomenon of physiological fruit drop is serious and pollination is unstable. In order to increase the yield of plum blossom, it is necessary to carry out artificial pollination. You can collect flower buds and pollen in flowering period, and then pollinate in sunny morning, so the success rate of pollination will be higher. Generally, it can be pollinated by acupuncture, daubing, spraying, or even patting pollen wrapped in cotton cloth.
6. Sparse flowers and fruits
We should carry out reasonable flower thinning at flowering stage, tap some long and dense flowers, sick flowers and weak flowers to ensure a reasonable fruit setting rate; Secondly, thinning fruit after fruit setting and removing some weak fruit, diseased fruit, abnormal fruit and dense fruit can reduce the probability of fruit dropping and improve the yield and quality of dried plums.
7. Prevention of pests and diseases
The resistance of prunes is still relatively strong, and the probability of onset is relatively small, but we still need to spray reasonable chemicals, such as carbendazim and chlorothalonil, which are all suitable; Some pests still occur from time to time, which is also common in many fruit trees. We can use trapping method to trap and kill, and at the same time, we can also use targeted chemicals to spray and kill, such as dimethoate milk and trichlorfon.
To sum up, farmers must master more correct planting techniques and scientific management methods if they want to increase the yield of prunes. I hope this article can help everyone.
