Eggplant is a common vegetable in our life. Farmers who grow eggplant know that eggplant needs more fertilizer and more water, especially in the result period. Therefore, in the process of planting eggplant, fertilizer and water management is a major link in the high yield of eggplant cultivation. So how do eggplants manage fertilizer and water?
1. Fertilization management
Fertilization for eggplants is recommended in accordance with the principle of “light application of seedling fertilizer, stable application of flower fertilizer, and application of fruit fertilizerâ€. After the planting and slowing the seedlings, combined with watering, the manure can be applied thinly or about 5 kg of compound fertilizer, and then applied once every 10 days to meet the growth and development needs of the seedlings.
After the first harvest, it is necessary to re-apply topdressing. It can be combined with cultivating and cultivating soil to embed the fertilizer into the soil. Generally, 20 kg of compound fertilizer is applied to the acre, or 10 kg of urea and potassium chloride, respectively, and it will be applied once every 10 days or so. For the needs of the growing fruit.
The most vigorous period of fruit harvesting is also the period when fertilizer is most needed, and the amount of fertilizer needs to be increased. In the middle and late stages, the aging of the plants and the decrease of the fertility are carried out. The root dressing method can be used. Generally, 1%-3% superphosphate leaching solution or 2%-3% potassium sulphate solution or 0.1%-1% urea solution can be sprayed on the foliar surface. , or 2%-3% compound fertilizer solution, spray once every 7-10 days, sprayed better in the morning or evening.
2, watering management
Eggplant requires more water and generally maintains 80% soil moisture. The result period is the period when the eggplant needs most water. The watering should be timely poured according to the condition of fruit development: the first flower should be controlled when the flower is open; when the fruit begins to develop and the bracts are stretched, watering should be promoted to promote the growth of young fruit. When the fruit grows to a diameter of about 3-4 cm, it grows fastest, and it is also the time when water is most needed. Pay attention to watering; re-watering 2-3 days before harvest to promote rapid fruit growth.
The above is the water and fertilizer management of eggplant. The area of ​​eggplant grown in China is gradually expanding. Many farmers will choose greenhouse greenhouse cultivation. In the process of eggplant cultivation, water and fertilizer management is the key. Farmers who grow eggplants must master the above management. Key points.
