Colonization 1. Land preparation Deeply turning up soil: fertilizing the soil. In the fall and winter season, the soil is deep-turned 25~30cm, and the soil will be used to improve the physical structure of the soil and kill the overwintering pests in the soil. In combination with site preparation, basal fertilizer is applied, and 3,000 to 3,500 kg of decomposed organic fertilizer is applied per 667m2, 50 to 100 kg of superphosphate, and 10 to 15 kg of potassium sulfate. All localities should regulate the amount of fertilizer according to soil fertility. Advocate the use of bio-organic fertilizer, to do the car according to local farming habits. 2. Cultivation methods Whether it is in open cultivation or protected cultivation, it should be covered with high mulching film. 3 timely planting Open field cultivation: In early March, the temperature is stabilized at 15°C for transplanting. Protected Cultivation In February, when the soil temperature at a depth of 10cm is stable at 13°C, it is suitable for transplanting. Field management Irrigation Irrigation should not be irrigated with large water and watered in cloudy water in the evening. Advocate sprinkler irrigation, drip irrigation, irrigation under the membrane. In the process of eggplant growth, the number of irrigations and the amount of irrigation in different growth periods are performed according to conventional cultivation management. 2. Other management Pruning, moderate pruning, usually lateral branches below the eggplant must be removed, leaving the trunk and 12 branches. Stand: The eggplant is exposed to the ground and facilities are cultivated. It is advisable to use wooden stakes or bamboo poles to set up the stand to fix the plants, combine the cultivating and weeding, and put the earth upside down to prevent lodging. Picking leaves: During the growth process, the old yellow leaves and diseased leaves of the base are removed promptly to facilitate ventilation and plant growth. Flower protection and fruit protection: In early maturing cultivation, plant growth regulators can be applied to protect flowers and fruits. However, 2.4D flower should not be used. Pest Control 1. Agricultural control Select pest-resistant species, cultivate age-appropriate seedlings and use of grafted seedlings; strictly implement the crop rotation system; use high ridge mulching film to cover cultivation; apply scientific fertilization and irrigation, reasonably close-growing, cultivate robust plants, promote early ridge closure, and remove heavy strains in time. Remove diseased leaves and diseased fruits and bring them out of the fields or sheds to burn or bury them deeply; clean the pastures, deepen the soil, and reduce the sources of winter diseases and insect pests. 2. Physical control Greenhouses are cultivated in high-temperature disinfection in greenhouses in the greenhouse; yellow locusts are killed in the field to kill locusts, whitefly, and leafminer; etc.; sweet and sour larvae are seduce and killed; frequency-reducing insecticidal lamps are used to trap and kill insects; field silver ash film or hanging silver ash Membrane strips repel aphids, cover insect nets, prevent insects and prevent diseases; artificially remove pest egg pieces and kill pests. 3. Biological control Protection and use of natural natural enemies such as ladybugs, grasshoppers, and bees are naturally controlled by the aphids. Bt emulsion, avermectin and other control of cotton bollworm, tobacco budworm. Actively promote the prevention and control of pests and diseases such as plant-derived pesticides, agricultural antibiotics, and microbial pesticides.
