Coring technique of eggplant

Eggplant is one of the common vegetables in our daily life, its own growth period is longer, when the plant height is more than 1.6 meters, it will cause management difficulties, so many vegetable farmers will take the heart-picking method to cultivate, the effect is better. So when does the eggplant pick its heart? What should you pay attention to? Let's get to know it.

1. When to pick the heart

In greenhouse cultivation, early coring of eggplant can shorten the growth and development period of eggplant and reduce its yield, while eggplant grows faster when it is too late, and the top stems and leaves will come into contact with the roof of the greenhouse, so that the growth will be restrained. Moreover, because of the influence of greenhouse film, it increases the probability of plant disease. Therefore, it is generally possible to pick the heart when the plant grows to 1.8 to 2 meters, and it is most suitable to pick the heart at this time.

2. The method of picking out the heart

Coring should be carried out according to the branching characteristics of eggplant, and two leaves should be left above the top inflorescence. The main function of keeping two leaves is to promote the growth and development of eggplant fruit through their photosynthesis. The coring time is usually carried out in the morning on a sunny day, which can promote wound healing and avoid bacterial and microbial infection. When coring, you can pinch off the growth nodes of the plant with your hands, and then take them out of the shed.

3. Matters needing attention

First of all, heart removal should pay attention to time and environment, which is suitable to be carried out in sunny days, large ventilation rooms and high humidity, so that it is beneficial to wound healing after heart removal, and at the same time, pathogenic bacteria can be avoided, and the removed stems and leaves should also be taken out of the shed. In addition, 1-2 leaves should be left on the end of the young fruit to facilitate the increase of photosynthate to supply the growth of the fruit, but also to shade the young fruit and avoid sunburn. After picking the heart, it is necessary to strengthen the management of fertilizer and water. Keep the soil in, carry fertilizer in the water when watering, ensure adequate nutrition, and spray foliar fertilizer rich in trace elements to avoid physiological diseases. For the prevention and control of diseases and insect pests should be timely, early detection, early control.
