Eggplant Fertilization Time and Method

Eggplant is a common vegetable in daily life, some farmers specialize in growing it to make money, but if you want eggplant to be high-yielding, you need to fertilize it well. What is the time and method of fertilizing eggplant?

First, the law of eggplant fertilizer requirement

The absorption of nitrogen, phosphorus and nitrogen by eggplant increased. The absorption of nitrogen, phosphorus and potassium at seedling stage only accounted for 0.05%, 0.07% and 0.09% of the total. In the early stage of flowering, the absorption increased gradually, and the nutrient absorption from fruiting stage to unsuccessful period accounted for more than 90% of the whole period, and the fruiting period accounted for about 2 prime 3. The nutritional needs of each growing period are different. Fertilizers in the early growing period mainly promote the vegetative growth of plants. With the progress of the growing period, the transport of nutrients to flowers and fruits increases. The absorption of nitrogen and potassium increased significantly during flowering. During this period, if there is a lack of nitrogen, the flower development is poor, the short style flower increases and the yield decreases.

2. Time and method of fertilization for eggplant:

1. Fertilizing eggplant before planting: the rotten organic fertilizer 4000kg, diammonium phosphate 40kg, potassium sulfate 30kg, calcium superphosphate 50kg can be applied per mu, and then turn over for the second time, and turn the fertilizer evenly.

2. Seedling stage: eggplant has a large demand for phosphorus in seedling stage, which can promote the flowering and fruiting of eggplant and advance the fruiting time. Therefore, it is necessary to strengthen the application of phosphate fertilizer at the seedling stage, but it is mainly farm manure. When the seedlings grow to about 5 true leaves, if it is found that the plant is lighter, foliar fertilizer should be sprayed properly to ensure the robust growth of the seedlings.

3. Fruit-promoting fertilizer: when the door eggplant enters the growth period, the fruit growth rate accelerates rapidly, and the whole plant will enter the fruit growth period. Stems and leaves will also enhance the growth ability, at this time the nutritional demand increases, the application of fertilizer should also be increased. This stage is also the first topdressing of eggplant, the purpose is to promote fruit growth, increase nutrition accumulation, is the key period of fertilization. Pay attention to the amount of fertilization, the main fertilizer ammonium sulfate-based, the application of hole application method, after fertilization to cover fine soil, pour enough water to improve the utilization rate of fertilizer.

4. Full fruit fertilizer: when eggplant enters the fruit expansion period, that is, the full fruit period, this time is also the period of high nutrition demand of eggplant. Therefore, the second topdressing work should be carried out at this stage, which is called fruit fertilizer. The fertilizer in the full fruit stage is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, and pay attention to the application of foliar fertilizer and a small amount of trace elements. Work together with watering to promote the absorption of fertilizer and enhance the immunity of the plant. Promote fruit expansion, but pay attention to the dosage, if the dosage is too much, it can easily lead to fertilizer damage of eggplant.
