What to do when eggplant fruit set rate is low? Teach you how to effectively increase the fruit set rate

Eggplant is a plant of the genus Solanum in the nightshade family. At present, there are quite a few varieties of eggplant, such as red eggplant, black eggplant, purple eggplant, and green eggplant. It is a common vegetable in our daily life, and also a favorite vegetable for many people. So when we grow eggplant, how do we increase the fruit set rate of eggplant? Let's learn about it together.

1. Pinching treatment

The rule of eggplant fruit set is generally that each branch fork sets one fruit, which means the more branch forks there are, the higher the fruit set rate of the eggplant will be. Based on this rule of eggplant fruit set, after transplanting, we should promptly carry out pinching treatment on the eggplant plants to promote the growth of new branches, and then after the new branches grow, continue with the next round of pinching treatment. The purpose of doing this is to promote branching, thereby increasing the fruit set rate.

2. Promote the weak and control the vigorous

If the eggplant plants are growing rather weakly, then without the influence of other external conditions, their natural fruit drop will also be especially serious. Of course, this does not mean that the better the eggplant plants grow, the higher their fruit set rate will be. In order to maintain the normal growth of eggplant plants and reduce flower and fruit drop, we need to reasonably promote the growth of weak plants and reduce the growth of overly vigorous plants, so as to increase the fruit set rate of eggplant. Generally speaking, this goal is achieved through fertilizer and water management, applying more fertilizer to weak seedlings and balanced fertilization to overly vigorous seedlings.

3. Artificial pollination

Using artificial pollination to achieve the effect of increasing the fruit set rate of eggplant is mainly a commonly used method for eggplant grown in protected cultivation. Eggplant flowers generally open at six in the morning, and the period from six to eight o'clock is not suitable for pollination. Generally, pollination should be carried out after eight o'clock, and the best pollination time is from eight to ten o'clock, when the pollination success rate is the highest, and the natural fruit set rate is also higher.

4. Hormone treatment

Using hormones to achieve the effect of increasing the fruit set rate of eggplant is a method currently adopted by many large-scale planting bases. Using hormones to increase the fruit set rate of eggplant is very simple, and the success rate of fruit set is also extremely high. At the same time, the yield of eggplant is also very good, but there is still a certain impact on quality. Commonly used hormones include 20 ppm 4-CPA and 30-40 ppm 2,4-D. Both hormones are used during the flowering period to prevent flower and fruit drop, thereby increasing the fruit set rate of eggplant.

5. Pest and disease control

Pests and diseases also have a great impact on the fruit set rate of eggplant. Among them, the main ones are the harm to eggplant from Verticillium wilt, red spider mites, and aphids, so we must make adequate preventive preparations. Generally, before sowing, the eggplant seeds need to be treated, for example, soaking the seeds in new high-fat film for 1 hour, or soaking the seeds in 55°C warm water for 15 minutes. Of course, there is also the need to carry out pest and disease control measures during the fruit set period of eggplant, selecting targeted pesticides for control, so as to achieve the purpose of protecting flowers and fruits.

The above are several methods introduced today about increasing the fruit set rate of eggplant, and I hope they can help everyone. Moreover, increasing the fruit set rate of eggplant is also the key to increasing eggplant yield. If everyone is interested in growing eggplant, you can leave a message for consultation.
