Detailed Explanation of the Latest Fertilization Methods and Key Technical Points for Eggplant
Eggplant cultivation is basically very common in our country, and the management work during cultivation is very important. Especially fertilization, because eggplant has a very large demand for nutrients during important growth periods such as the full fruit stage and flowering stage. Therefore, when applying fertilizer, we must not only meet the nutritional growth needs of eggplant, but also appropriately adjust the fertilizer according to the growth conditions. So below, the editor has brought you the fertilization methods for eggplant. Let's take a look together!
1. Apply sufficient base fertilizer
The growth cycle of eggplant is relatively long, its roots extend deeply, and its branches and leaves are lush. It is a vegetable that likes fertilizer and needs fertilizer. Therefore, applying sufficient base fertilizer is the key to ensuring the healthy growth of eggplant, and if greenhouse plastic film cultivation is used, topdressing in the middle and late stages is relatively difficult, so the amount of base fertilizer applied also needs to be increased. The fertilizer is mainly farmyard manure, and the farmyard manure must be fully decomposed and properly fermented to prevent fertilizer loss. It can also eliminate harmful substances in the fertilizer, improve the utilization rate of the fertilizer, and promote the nutrient absorption of eggplant.
2. Cultivate seedlings
The growth of eggplant seedlings is closely related to the growth of eggplant throughout the entire growth period, and it is especially important for flower bud differentiation. Therefore, topdressing at the seedling stage is very important. At the seedling stage, the demand for phosphorus is relatively large, which can promote the flowering and fruiting of eggplant and advance the fruiting time. Therefore, at the seedling stage, the application of phosphate fertilizer should be strengthened, but it is still mainly farmyard manure. When the seedlings grow to about 5 true leaves, if the plant color is found to be relatively light, foliar fertilizer should be sprayed appropriately to ensure the robust growth of the seedlings.
3. Fruit-promoting fertilizer
When the first eggplant enters the growth period, the growth rate of the fruit accelerates rapidly, and the entire plant will enter the fruit growth period. The stems and leaves will also enhance their growth capacity. At this time, the nutrient demand increases, and the application of fertilizer must also be increased. This stage is also the first topdressing for eggplant, with the purpose of promoting fruit growth and increasing nutrient accumulation. It is a key period for fertilization. When fertilizing, pay attention to the amount. The main fertilizer is mainly ammonium sulfate, applied by the hole application method. After fertilizing, cover with fine soil and water thoroughly to improve the utilization rate of the fertilizer.
4. Full fruit fertilizer
When eggplant enters the fruit expansion period, that is, the full fruit stage, this is also a period of high nutrient demand for eggplant. Therefore, at this stage, the second topdressing work should be carried out, which is called full fruit fertilizer. The fertilizer at the full fruit stage is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, and attention should also be paid to the application of foliar fertilizer and a small amount of trace elements. Together with watering work, it promotes the plant's fertilizer absorption and enhances the plant's immunity. It promotes fruit expansion, but attention should be paid to the amount. If the amount is too much, it can easily cause fertilizer damage to eggplant.
The above is a brief introduction to eggplant fertilization methods. In fact, when fertilizing, not only the fertilization methods need attention, but many other aspects are also very important. For example, dosage, location, etc. If you want to know what other specific precautions there are when fertilizing, you can enter our website to view related articles!
