Detailed Guide to the Latest Techniques for Pinching Eggplant

Eggplant is one of the common vegetables in our daily lives. It has a relatively long growth period, and during cultivation, once the plant height exceeds 1.6 m, it becomes difficult to manage, so many vegetable growers adopt the pinching method for cultivation, with good results. So when should eggplant be pinched? What should be noted when pinching? Let's learn about it together.

1. When to pinch

In greenhouse cultivation, pinching eggplant too early easily shortens the eggplant's growth and development period, leading to reduced yield; while pinching too late allows the eggplant to grow faster, and the top stems and leaves will touch the greenhouse roof, which not only inhibits growth but also, due to the influence of the greenhouse film, increases the chance of the plant developing disease. So generally, when the plant grows to 1.8-2 m, it can be pinched, and this is the most suitable time for pinching.

2. Pinching method

Pinching should be carried out according to the branching characteristics of the eggplant. When pinching, it is advisable to leave two leaves above the top inflorescence; the main purpose of keeping these two leaves is to synthesize nutrients through their photosynthesis to promote the growth and development of the eggplant fruit. Pinching is generally done on a sunny morning, as this can promote wound healing and avoid infection by pathogens and microorganisms. When pinching, simply pinch off the plant's growing point with your hands, then take it out of the greenhouse.

3. Precautions for pinching

First, when pinching, pay attention to the time and environment. It is suitable to do it on sunny days, in greenhouses with large ventilation, and under relatively high humidity, as this helps wound healing after pinching and can also avoid infection and disease caused by pathogenic bacteria. The removed stems and leaves should also be taken out of the greenhouse. In addition, when pinching, leave 1-2 leaves above the young fruit to help increase photosynthetic products to supply the fruit's growth, and also to provide shade for the young fruit to avoid sunscald. After pinching, strengthen fertilizer and water management. Keep the soil supplied, and when watering, bring fertilizer with the water to ensure sufficient nutrition. At the same time, spray foliar fertilizer rich in trace elements to prevent physiological diseases. For the prevention and control of pests and diseases, act promptly, detect early, and control early.
