Causes and Countermeasures of low Fruit setting rate of Apricot

Apricot is a deciduous tree with strong adaptability, cold resistance and drought tolerance. its fruit is one of the common fruits, sweet and juicy, rich in nutrition, rich in sugar, protein, calcium and phosphorus, and is an important economic fruit tree in China. But many fruit growers often have a low fruit setting rate. What's going on at this time? How to improve the fruit setting rate of apricot trees? Let's take a look.

First, the reason for the low fruit setting rate

1. Varieties: there are many varieties of apricot, and some varieties have low seed setting rate, such as sweet hazelnut, wheat yellow apricot, red jade apricot and so on. The introduced varieties such as Golden Sun Apricot, Kate Apricot and Italy No.1 have higher seed setting rate and strong cold tolerance.

2. Environmental discomfort: when planting, the environmental conditions are not suitable for the growth and development of apricot trees. If you encounter a low temperature climate during the flowering and fruiting period, the flowers and fruits will freeze and stop growing, and fall off in serious cases. Especially in orchards planted in valleys and depressions, it is easy to cause freezing injury and lead to flower and fruit drop.

3. Improper cultivation: due to improper management and extensive cultivation, the orchard leads to tree weakness, lack of nutrition, more abortive flowers, lack of nutrients and fruit drop. In addition, excessive pruning, partial application of nitrogen fertilizer, watering too frequently, these will lead to plant overgrowth, seize a lot of nutrients, resulting in insufficient supply of flowers and fruits, flowers and fruits, resulting in low fruit setting rate.

2. Methods to improve fruit setting rate

The main contents are as follows: 1. Choose to plant in the land with high and flat terrain, deep soil layer, loose and fertile soil, good drainage and leeward to the sun, so as to avoid the accumulation of cold air and the occurrence of frost injury to flowers and fruits.

2. Seed selection: the varieties with high complete flower ratio, high self-flowering seed setting rate and strong cold resistance should be selected, especially if they are planted in the apricot orchard at late frost.

3, cold prevention: to do a good job of cold prevention measures, you can postpone the flowering, so as to miss the late frost, so as not to cause falling flowers and fruits. In early spring, the ground can be thawed by watering and covering straw, so as to accelerate the rise of ground temperature, promote the growth of apricot trees, and white the trees to resist the severe cold.

4. Artificial pollination: when the effect of natural pollination is poor, artificial pollination can be used to provide the best method of apricot fruit setting rate. The suitable varieties of anthers were collected and placed in the environment of 26 degrees at room temperature to disperse pollen as soon as possible. The pollen was collected and inseminated successfully by the method of point insemination. The time of insemination was 1-2 days after single flower flowering.

5. Hormone spraying and fertilizer spraying: Aido water collecting agent can be sprayed at full flowering stage, and borax solution is mainly sprayed to improve the spraying method, which can improve the utilization rate of chemicals and fertilizers, accelerate plant absorption and improve fruit setting rate.

The above are the reasons and countermeasures for the low fruit setting rate of apricot trees. I hope it can help you. If you want to know more about fruit tree planting, please pay attention to us.
