Eggplant is a fertile vegetable and is suitable for cultivation on soils with high organic matter content and strong water and fertilizer retention capabilities. For growers, proper fertilization is the key to high eggplant yields. How to fertilize eggplant for high yield?

1. The eggplant in the greenhouse should be fertilized with enough base fertilizer

Apply 6000 kilograms of organic fertilizer per mu. If it is an old shed, the application amount can be reduced, and an additional 20 to 30 kilograms of potassium sulfate can be applied.

The eggplant base fertilizer should be fully spread with organic fertilizer and potash fertilizer, and then turned into the soil. It is important to note that the organic fertilizer must be fully decomposed and treated with a professional starter as much as possible.

2. Phosphate fertilizer should be applied more during the eggplant seedling stage

During the seedling stage of eggplant, more phosphorus fertilizer is applied at the seedling stage, which can result in earlier results. Generally, 9 square meters of seedbed can be applied with 200 kg of sieved and decomposed organic fertilizer, 0.5 kg of calcium superphosphate and 0.5 kg of potassium sulfate.

When the eggplant seedlings grow to 4-5 true leaves, if the lower leaves are lighter in color, 0.1%-0.2% potassium dihydrogen phosphate or urea can be sprayed on the foliage, which can ensure the cultivation of strong seedlings.

3. Topdressing fruit fertilizer in time

The whole plant enters the period of fruit growth, stems and leaves also begin to grow vigorously, and the amount of fertilizer required increases. At this time, the first top dressing is carried out, which is called fruit fertilizer, which is the key fertilization period.

For eggplant fertilization, apply 30-40 kilograms of ammonium sulfate or 15-20 kilograms of urea per acre, apply in holes or furrows, cover with soil and water after application.

Fourth, the expansion of eggplant fertilizer

When the fruit of "Dai eggplant" swells, it is the peak period of eggplant's need for fertilizer. At this time, the second top dressing is carried out, that is, enlarged fertilizer.

The bulking fertilizer is mainly nitrogen fertilizer, along with phosphorus and potassium fertilizers, and also pay attention to the foliar topdressing of calcium, boron, zinc and other medium and trace element fertilizers.

5. Foliar spraying of eggplant

From the fruiting period, 0.2%-0.3% urea, 0.2%-0.3% potassium dihydrogen phosphate, 0.1%-0.2% magnesium sulfate and other fertilizers can be sprayed according to the growth. Usually once every 7-10 days, spray 2-3 times in a row.
