Field management techniques of eggplant after planting

After planting slow seedlings, eggplant should be ploughed and loosened as early as possible, and the field soil is loose, which is beneficial to increase soil temperature and promote root growth. Eggplant has a long growth period and high requirements for fertilizer and water. The principle of watering is to control first and then promote. Generally speaking, watering should be controlled before the door eggplant is set, and the slow seedling water after planting should be properly watered gently when necessary, and the seedlings should be ploughed and squatted immediately after watering. When the diameter of the door eggplant reached more than 3 cm and the fruit began to grow rapidly, the squatting seedlings ended and began to be watered. After the temperature rises, more and more water is needed, especially when eggplant and Simandou are relatively expanded, it usually takes 4 to 5 days to water once, so that the soil relative humidity is maintained at about 80%, and watering should be reduced when the temperature gradually drops in the later stage. Eggplant is not resistant to waterlogging, but also afraid of high temperature and humidity, retting roots and rotten fruit, pay attention to drainage in the rainy season, it is appropriate to water in the morning and evening in summer, in case of thunderstorm and hot rain, we should also take the measure of "waterlogging garden" to release clear water over the field and reduce the soil temperature.

Eggplant likes fertilizer, so it is very important to supply seedlings and promote fruit in the early stage. After seedling retardation, combined with ploughing and shungou, about 100 kg per mu of manure is applied to eggplant and Simandou. In the expansion period of eggplant and Simentou, each manure is sparse or nitrogen. For autumn eggplant with long growing period, it is necessary to continue to fertilize and prolong leaf bolls to promote fruit growth.

Before and after fruit-setting of eggplant, eggplant retains two cymbal-shaped branches and erases the rest of the axillary buds on the main stem in order to reduce nutritional consumption and facilitate ventilation and light transmission. In principle, the leaves are not picked during the growth period, especially the functional leaves in the upper layer of the plant, which has a strong photosynthesis and has a great impact on the fruit, let alone should not be removed. However, with the harvest of the fruit, the old leaves and yellow leaf disease leaves in the lower part of the plant can be removed, which is helpful to improve the ventilation and light transmission condition and reduce the occurrence of the disease.
