Key points for choosing and using foliar fertilizer on eggplant

Foliar feeding is a supplement to the plant's absorption of nutrients, in which growers spray the nutrients the plant needs directly onto the leaves. This supplements the shortfall of root fertilization. Below, let's find out what foliar fertilizer is generally used on eggplant to make the fruit swell quickly, and what the application techniques are.

1. What foliar fertilizer is generally used on eggplant?

1. After spraying eggplant with amino acid foliar fertilizer, within ten seconds it spreads radially and is absorbed and transformed by the eggplant plant in multiple directions, thereby increasing the eggplant's endogenous substances, regulating physiological metabolic activity, and raising chlorophyll content and photosynthesis. This can prevent the appearance of small leaves, curled and shrunken leaves, withered yellow leaves, and spotted leaves, as well as disorders such as flower and bud drop, boll drop, rough dwarfing, flower rot, withering and premature aging in eggplant.

2. Only by reasonably shaping the planting density and plant architecture of eggplant can flowering be better promoted. During planting, manual pollination should be strengthened so that the eggplant grows and swells quickly, thereby increasing eggplant yield and ensuring higher output and income.

3. Spraying eggplant with foliar fertilizer can promote early maturity, bringing it to market half a month earlier, capturing the market, and thereby increasing one's own economic returns.

2. What are the application techniques for eggplant foliar fertilizer?

1. Fertilizer requirements of eggplant

(1) Macroelements: among the three major elements nitrogen, phosphorus and potassium, eggplant has the greatest demand for potassium, followed by nitrogen fertilizer, and the least demand for phosphorus fertilizer, with a ratio close to 3:1:4.

(2) Medium and trace elements: elements such as calcium and magnesium have a relatively large effect on eggplant growth. When eggplant lacks calcium, the plant grows slowly, the growing point becomes deformed, and the leaf margins of young leaves lose their green color; when it lacks magnesium, the area near the leaf veins, especially near the main vein, turns yellow, the leaves lose their green color, and the fruit becomes smaller and develops poorly.

2. How to use eggplant foliar fertilizer

(1) Dilute the foliar fertilizer with water. High-concentration powder formulations need to be dissolved by adding water. For the dilution factor and the calculation method for adding water, take Liheng 300ml as an example here: 0.3L*1000=300L, that is, add 300 kg of clean water and stir.

(2) Sprayer: it is best to spray with one that has a good atomization effect, as this can increase the foliar absorption rate and reduce waste.

(3) Foliar spraying: when spraying eggplant, it is best to focus on the underside of the leaves and the surface of the eggplant, which can effectively swell the eggplant fruit and promote rapid nutrient absorption. Spray evenly once; do not go back and forth spraying multiple times.

3. What are the usage and dosage of eggplant foliar fertilizer?

1. When spraying high-potassium, high-calcium amino acid foliar fertilizer, avoid high-temperature weather, because high-temperature weather will quickly evaporate the high-potassium, high-calcium amino acid foliar fertilizer on the eggplant. Therefore, choose an overcast day, which helps the high-potassium, high-calcium amino acid foliar fertilizer be fully absorbed by the eggplant.

2. When mixing and using with strongly alkaline pesticides, first choose a small area for testing, and only after no other problems occur should it be promoted over a large area. Moreover, fertilizing eggplant can effectively alleviate various types of pesticide damage, fertilizer damage and freezing damage.
