The Latest Methods to Improve Plum Fruit Set Rate
The plum is a fruit with fairly high recognition in our country. It is loved by many people, and plum trees are now planted across a very wide area in our country. However, many people find when growing them that their fruit set rate is very low. So how to improve the fruit set rate has become something many fruit growers need to pay close attention to. So let me introduce several methods for improving the plum fruit set rate. Let's take a look!
1. Planting and pollination
When planting plum trees, we need to pay attention to reasonably configuring the tree specifications within the orchard. We must ensure there is a certain number of pollinizer trees in the orchard, especially where a relatively large proportion of the trees have low fruit set or produce little pollen. The number of pollinizer trees should be maintained at around 30 percent. Then during the flowering period, bees can be released appropriately for pollination, using bees to carry out pollination work for the plum trees. Artificial pollination should also be carried out appropriately, using a writing brush or a brush to transfer pollination pollen onto the flowers of the varieties, improving the pollination rate.
2. Temperature control
Plum trees are fairly sensitive to temperature changes. When planting, we need to pay attention to doing a good job of site selection, and it is not suitable to choose low-lying places that easily accumulate water. This avoids water accumulation and poor ventilation leading to insufficient temperature, which would affect plum growth. Then during the flowering period of the plum trees, we need to pay attention to observing weather changes, and when the temperature changes greatly, we must make preparations. Smoke can be used appropriately to prevent advection frost, watering should be reasonable, and when frost occurs, the trees should be sprayed appropriately at night to reduce the frost phenomenon and improve the plum fruit set rate.
3. Shaping and pruning
The plum tree's tree form is relatively large, and during the growing process we need to pay attention to controlling the tree form well and doing a good job of shaping and pruning. For some trees growing too vigorously, the overly dense and overly long branches should be cut off, bud removal should be done well, and the angle of the tree canopy should be widened. Then the pruning method should be reasonably adjusted according to tree age and tree vigor. Reasonable pruning can not only concentrate nutrients in the flowers and fruits, but also improve the permeability within the fruit tree and enhance the plum tree's growth capacity. Then for weak-growing trees, light pruning or no pruning can be used to increase their nutrients and improve the fruit set rate.
4. Pest and disease control
Plum trees have a great many pests and diseases, and many of them harm the flowers and fruits of the plum tree. This causes various adverse phenomena such as flower and fruit drop and rotten fruit in plum trees. Therefore we must also focus on doing a good job of pest and disease control for plum trees and enhance the plum tree's disease resistance. During the full flowering period, we should pay attention to spraying agents such as sterilization fat and do a good job of disinfection. Then in winter we should do a good job of clearing the orchard, removing diseased and disabled remnants, weeds, and so on within the orchard, and deeply plow the soil to destroy the overwintering sites of pathogens. After disease occurs, corresponding measures should be taken promptly to ensure the healthy growth of the plum trees and increase yield.
The above is a brief introduction to how to improve the plum fruit set rate. The fruit set rate of plum trees has a direct relationship with their yield, so everyone must pay close attention to it. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
