Fertilization type

Base fertilizer

The type of base fertilizer in summer is mainly organic fertilizer, and the best application is in May. Because at this time, the roots and fruits grow well, and the branches and leaves will stop growing. At this time, fertilization will not cause the second growth. After fertilization, water will be poured, and the soil, fertilizer and roots will be closely connected to promote the absorption of fertilizer

Autumn base fertilizer should be applied after fruit harvest. At this time, the root system is in the growth period, and it will heal quickly even if it is injured. When fertilizing, part of the small roots can be cut off, which can trim the roots and promote the growth of new roots. In terms of the proportion of fertilizer, nitrogen fertilizer can be appropriately increased to promote the growth of branches and leaves

Topdressing

Topdressing before flowering: topdressing in early may mainly selects nitrogen, phosphorus and potassium fertilizer. Timely topdressing can meet the needs of flowering and fruit setting of plants

Topdressing with backward flowers: the pomegranate flower is backward and needs topdressing in time. This is the biggest period when pomegranate needs fertilizer. The development of young fruits and the growth of new shoots need sufficient nutrients. At this time, appropriately increasing nitrogen fertilizer can reduce physiological fruit drop. If the amount of topdressing before flowering is large, the amount of fertilization can be reduced appropriately after flowering

Fertilization method

Shallow ditch fertilization

Dig a deep circular ditch at the outermost edge of the flowerpot, apply fertilizer into it, and then cover it with soil. When digging, be careful not to cut off the root system of pomegranate. This method is applicable to the seedlings of pomegranate

Hole fertilization

Directly dig a small pit about 20cm deep next to the pomegranate, pour the fertilizer into it, and then cover it with soil

Foliar fertilizer

This method is simple and easy, the amount of fertilizer is small, and the effect is fast. Mainly dilute the fertilizer and spray it on the leaf surface. The absorption is obvious 10-15 days after spraying. This method can improve the nutritional status of the root, promote the development of the root system and enhance the absorption capacity. However, foliar fertilization cannot replace soil fertilization, and the two should complement each other

However, the best time for foliar fertilization is before 10 a.m. and after 4 p.m. when the temperature is moderate and the sun is not strong
