Time and method of fertilization for eggplant

When sowing, an appropriate amount of fully mature farm manure can be applied. Seedling stage: you can apply appropriate amount of phosphate fertilizer, farm fertilizer, and spray appropriate amount of foliar fertilizer. Fruit growth period: appropriate amount of ammonium sulfate fertilizer can be applied. Full fruit period: can apply appropriate amount of nitrogen fertilizer, phosphorus and potassium fertilizer, and spray appropriate amount of foliar fertilizer and trace elements.

First, apply sufficient base fertilizer

1. Eggplant has a very long growth cycle, deep root extension and luxuriant branches and leaves, so it is a vegetable that likes fertilizer and needs fertilizer, so it is the key to ensure the healthy growth of eggplant. If plastic film is used to plant eggplant, it is generally not so convenient to top fertilizer in the middle and later stage, so it is necessary to apply sufficient base fertilizer.

2. In general, farm manure is mainly applied, which should be fully mature and fermented to prevent fertilizer loss, eliminate harmful substances in fertilizer, effectively improve the utilization rate of fertilizer, and promote eggplant to absorb nutrients.

Second, cultivate seedlings

The main results are as follows: 1. The growth of eggplant seedlings is closely related to the growth of eggplant in the whole growth period, especially for flower bud differentiation, so topdressing should be carried out in time in the seedling stage, and eggplant has a great demand for phosphorus in the seedling stage. Phosphorus can promote eggplant to blossom and bear fruit earlier.

2. therefore, in the seedling stage, an appropriate amount of phosphate fertilizer can be applied, but it is mainly farm manure. When the seedlings grow to about 5 true leaves, if the plant color becomes lighter gradually, foliar fertilizer should be sprayed properly, which is beneficial to the healthy growth of the seedlings.

Third, promote fruit fertilizer

The main results are as follows: 1. When the eggplant enters the growing period, the fruit growth rate will be accelerated, and the whole plant will enter the fruit growth period, the stem and leaves will also increase growth, and the nutritional demand at this stage will also increase. Therefore, the application of fertilizer should also be increased.

2. this period is also the first topdressing of eggplant. Fertilization is mainly to promote fruit growth and increase nutrition accumulation. When applying fertilizer, we should pay attention to the amount, mainly ammonium sulfate, and hole application can be adopted. After fertilization, a small amount of fine soil should be covered, and the soil should be watered thoroughly, which can improve the utilization rate of fertilizer.

Fourth, rich fruit fertilizer

The main results are as follows: 1. When eggplant enters the stage of fruit expansion, it is also the period of high nutrition demand of eggplant, so it is necessary to carry out the second topdressing work, also known as full fruit fertilizer, mainly with nitrogen fertilizer and supplemented by phosphorus and potassium fertilizer.

2. Foliar fertilizer and a small amount of trace elements can also be applied, which can be fertilized at the same time of watering, which is helpful to promote the fertilizer absorption of the plant, improve the immunity of the plant, and promote the expansion of the fruit, but pay attention to the dosage, if the dosage is too much, it will easily cause fertilizer damage to eggplant.
