The Trilogy of High-yield cultivation of eggplant

I. watering, fertilizing and pruning

Before the fruit expansion period, water should be properly controlled. After the fruit enters the expansion period, the water supply is guaranteed and watering should be carried out in the morning. In the process of eggplant growth, diseased, old, yellow leaves and diseased fruits should be removed in time, and diseased plants should be removed. Wash your hands with strong soapy water when pruning and crossing to prevent virus transmission during operation. Door eggplant can not be watered before expansion, in the door eggplant length of 3-4 cm, the first topdressing irrigation, with urea 15 kg, potassium sulfate 7 kg mixed hole application, and combined with watering, the amount of water should not be too large. When the second topdressing began to expand, 15 kg of urea was used per mu, and the interval between the two topdressing was about 10-15 days. At the same time, we should actively take measures to protect flowers and fruits, such as choosing plant hormones to spray flowers to promote fruit setting.

? II. Control of diseases and insect pests

Adhere to the plant protection policy of "prevention first, comprehensive prevention and control". Use frequency vibrating insecticidal lights, black lights, double-wave lights and other traps to kill pests in the open field. Pay attention to the rotation of drugs and strictly control the safety interval of pesticides, such as Botrytis cinerea can be used 1500 times, 3 times every 1 day, 64% mancozeb powder is used 3 times every 3 days, Verticillium wilt and Fusarium wilt can be used twice every 5 days. Aphids were sprayed with 400g / mu of 22% dichlorvos smoke, used 5 times every 5 days, and tea yellow mites were used 1000-1500 Fu solution, 10% imidacloprid wettable powder, twice every 3 days.

? III. Harvest time

Those who have applied chemical pesticides shall be tested for pesticide residues 1-2 days before harvest, and shall be collected in time after they are qualified, and will be put on the market in graded packaging. Harvest basis: the suitable harvest time is to narrow the distance between the deep and shallow zigzag stripes under the eggplant library. Early harvest affects yield, late harvest quality decreases, but also affects fruit growth, but eggplant seedlings should be harvested late when they are booming. Harvest time: choose afternoon or evening harvest. The branches are crisp and easy to break in the morning, and the water content is low and the quality is poor at noon. To prevent breaking branches or pulling off fruit stalks, it is best to harvest with scissors that prune fruit trees.
