Generally, you can choose to sow in summer and autumn. Before sowing, you should disinfect the seedbed properly to cultivate strong seedlings. After one month, the seedlings can be transplanted into the greenhouse. Generally, 2500-2800 plants are planted per mu, and the roots are sown. Cut in time, keep two pieces, break the others, and bandage the support in time. If you set fruit, you can use balanced compound fertilizer or water-soluble fertilizer to spray 10 ~ 20kg of water, or spray it once a week, about three times. Eggplant fruit can be supplemented with 1-2 times of urea, about 15 kg per mu, and sprayed with 1-2 times of marine myopia, which can promote root growth, improve disease resistance and improve eggplant fruit quality. Later, the temperature dropped, the plastic shed was closed sooner or later, and it was ventilated during the day. Eggplant is easy to drop flowers and fruits, which can be adjusted by growth regulators.

It can remove diseased leaves in time, prevent and control pests, especially underground pests, use bifendate to prevent and control underground pests, use carbendazim, pyrazoline and other drugs to prevent and control diseases, and add sea elf foliar fertilizer to enhance the disease resistance of eggplant trees.

Eggplant needs nitrogen fertilizer most, so eat less at high temperature. The dosage of urea per mu should generally be controlled within 30 kg. Because of high temperature and energy saving, the transformation speed of urea after being injected into soil is relatively fast, and the excess part may be lost after the plants meet the demand. In particular, the proportion of sand loss will be even greater. It is advisable that bicarbonate should not exceed 40 kg per mu of city appearance. If the city is too big, it will not only lose nutrients, but also cause ammonia damage to eggplant leaves and fruits.

It has become a habit for vegetable farmers to spray water when harvesting chemical fertilizers, but this method can not be used in high temperature period in summer. Because of the high temperature, a large amount of ammonia will volatilize when spraying fertilizer, which will reduce the efficiency of fertilizer. Especially bicarbonate is more likely to cause ammonia poisoning in eggplant. Ditching or bloodletting is the most effective. After topdressing, bury the soil with a thickness of less than 5 cm to reduce the volatilization of effective components of chemical fertilizer. Eggplant needs nitrogen fertilizer most, but phosphorus and potassium fertilizer are also indispensable. When you pour fertilizer, you can't recycle nitrogen fertilizer every time. It is best to harvest 3 yuan compound fertilizer twice in the fruiting period, twice and not more than 40kg per mu, so as to meet the demand of eggplant growth and fruiting.

In the early stage of eggplant bacterial wilt, only one or several leaves of individual eggplant faded, gradually contracted, and then expanded to the whole plant. (william shakespeare's "Hamlet" and "Eggplant Famous Words") () In the later stage, the diseased leaves dry up and turn brown, and they turn brown from the middle of the stem, and the seriously diseased plants fester or appear hollow. After the emergence of diseased plants, the disease spreads quickly, especially when the weather is fine after heavy rain or showers, the disease is more rapid and the condition is aggravated.

Pathogens mainly overwinter in the soil, and in the second year, rain, irrigation and soil spread, invaded from the wounds at the lower part of the host root and stem, and propagated and spread in the catheter. The pathogen can survive for about 200 days in the host, 2 ~ 6 years in the soil, and its condition is serious under high temperature and high humidity. Twain 25 is the highest peak of plant diseases. Other conditions causing eggplant bacterial wilt are: slightly acidic soil, too high field temperature, long-term rain or sunny days after heavy rain, high temperature and high humidity weather, and insufficient nitrogen and potassium fertilizer in farmland.
