The shape and size of fruits vary greatly. The leaves are oval, the flowers are purple, the fruits are obovate or oblong, the color is purple, and some are light green or white. They are common vegetables and also refer to the fruit of this plant.
Eggplant likes high temperature, the optimum temperature for seed germination is 25 -30 degrees Celsius, and the optimum temperature for seedling development is 25 -30 degrees Celsius during the day, 15 degrees Celsius -20 degrees Celsius at night, which is lower than 15 degrees Celsius, causing slow growth and flowering. /kloc-metabolic disorder below 0/0℃.
Eggplant needs high-intensity light time. Under the condition of long sunshine and high intensity, eggplant grows vigorously, with good flower bud quality, high fruit yield and good coloring.
Eggplant needs less water before molding, but it needs more water after rapid growth, and it needs the most water before and after harvest, so it is necessary to fully meet the water demand. Eggplant likes water and is afraid of it. When the soil is wet and poorly ventilated, it is easy to cause root retting, and the air humidity is high, which is easy to cause diseases.
It is suitable for cultivation in soil with rich organic matter and strong water and fertilizer conservation ability. Eggplant has a large demand for nitrogen fertilizer, which delays flower bud differentiation and obviously reduces the number of flowers, especially in full bloom. If nitrogen is insufficient, more short flowers will appear and plants will not develop well. Under the condition of low nitrogen fertilizer level, the effect of phosphorus fertilizer is not obvious, and the absorption of potassium increases sharply in the later stage.
