Eggplant is a very popular vegetable, but many farmers do not know how to effectively increase the yield of eggplant. As the demand for eggplant market continues to rise, it is very important to learn more ways to increase eggplant production. The growers introduced that it is more appropriate to grow eggplants in a solar greenhouse because of the higher yields. Let's take a look at the cultivation techniques of growing eggplant in the solar greenhouse, and hope to help the growers. First, timely seeding Eggplant is a kind of vegetable that is warm and heat-resistant, but it is afraid of dry heat and cold. The suitable temperature for growth is 15-30 degrees. It should be kept at 25-30 degrees for a long time in one day, and keep the temperature difference between day and night. Not less than 15 degrees at night). Therefore, according to the local temperature and light and other climatic conditions, the thermal insulation performance of the solar greenhouse, the market demand, the cultivation and management technology level of the growers and other factors are considered comprehensively, and the planting times are selected, but the cultivation and management of the wintering hoe is difficult. Second, choose the right variety (1) Need to select the variety according to the lighting conditions In winter, the sunlight in the greenhouse is weakened, purple orchids are planted, and the fruits are not easy to be colored. Professional growers recommend that you choose green varieties such as Xi'an green eggplant and Kaifeng green apple. If you can take effective light-filling measures, you can also grow purple varieties, such as Beijing six-leaf eggplant, Liaojiao No.3 and so on. (2) Grafting cultivation Japanese citrus, wild eggplant, etc. can be used as rootstocks, cultivars can be used as scions, and grafting cultivation (anti-Verticillium wilt) can be carried out by splicing or beveling. (3) The mulching film is covered with mulch and covered with sorghum. Third, enhance the lighting (1) Selecting a greenhouse film If the colorless transparent plastic film is selected as the shed film, it is beneficial to the coloration of the purple eggplant fruit. If it has a light blue film or other color film, the fruit of the purple eggplant is not easy to be colored. (2) Moderate close planting and pruning According to soil fertility, variety characteristics, water and fertilizer conditions, etc., the number of plants per acre is generally recommended to plant 3000-3500 plants for early maturity, 2500-30000 plants for mid-late ripe crops, and more double-pruning pruning (ie, above the eggplant, all staying two) One branch, one eggplant per branch), remove the lower old leaves in due course, and leave 2-3 leaves on the top eggplant in time to top. (3) Artificial fill light The greenhouse is planted from November to April of each year, and additional lighting measures are required. Fourth, variable temperature management On sunny days, 25-30 degrees in the morning, 22-20 degrees in the afternoon, 18-15 degrees in the middle of the night, and 15-10 degrees in the middle of the night. The temperature can be appropriately lowered on a cloudy day. 5. Fertilization and watering (1) Rational fertilization Apply 5-6 square decomposed organic fertilizer per mu to base fertilizer, 2/3 application, and 1/3 ditch application; generally start topdressing after the eye of the eggplant, each layer of fruit will be followed by 1 fat, organic fertilizer, cake fertilizer , human excrement, etc. (all must be cooked), chemical fertilizers are ammonium sulfate, ammonium nitrate, urea, potassium sulfate, diammonium phosphate, etc., with water. (2) Foliar fertilizer Spray with 0.2% urea and 0.3% potassium dihydrogen phosphate at the seedling stage and the flowering result period as appropriate (afternoon). (3) Scientific watering Generally, it is watered by submerged under-film irrigation technology. It should be watered in the morning on a sunny day. The water volume should not be large, prevent flooding of large water, strengthen ventilation management, reduce humidity; pay attention to weather forecast, avoid rainy days and rainy days after watering. Watering is properly controlled at the beginning of the disease. Sixth, to prevent falling flowers and fruit In order to prevent falling flowers, the plants are treated with plant growth regulators. After the fruit is inflated, the residual flowers that have not fallen off are gently removed to prevent infection with gray mold. Timely harvesting of fruits In summary, in order to improve the output of eggplant, it is necessary to use scientific planting techniques. I hope this article will help everyone.
