What medicine can make Myrica rubra bigger?

At this stage in May and June, it is necessary to provide a large number of nutrients such as potassium and phosphorus to fruit trees to prevent the lack of trace elements such as calcium, magnesium, iron, zinc and boron. At the same time, it is necessary to spray functional fertilizers on the leaves and control watering to promote the expansion and development of fruits, evenly color them and improve the sugar content and taste.

Let's talk specifically about how to make bayberry fruit bigger:

1. Potassium supplementation

Calcium supplement

Operation method: During the young fruit period and fruit expansion period, spray 1 times of calcium nitrate solution or chelated calcium every 7- 10 days, mainly on the calyx depression of the fruit, and spray twice.

Magnesium supplementation

Operation method: spraying magnesium sulfate on the leaves. Ordinary fruit trees or fruit trees with mild magnesium deficiency can be sprayed with 1-2% magnesium sulfate 1-2 times, and fruit trees with severe magnesium deficiency can be supplemented with 1.5 kg of magnesium sulfate per mu for root fertilization.

Step 4 supplement boron and zinc

Operation method: For the fruit trees lacking boron and zinc, 0. 1-0.3% borax and 0.3-0.4% zinc sulfate can be sprayed according to the tree conditions.
