Fruit trees should pay attention to calcium

Calcium plays a role in balancing the physiological function of the body in the growth process of fruit trees. For example, the effective calcium content in orchards with serious water accumulation, low organic matter content, and strong soil acidity is often too low, which affects the growth and development and fruiting of fruit trees.

The main symptoms of calcium deficiency in fruit trees: When the plant grows to about 20 cm, the tip of the young leaf curls into a hook shape. After a few days, it turns brown and brown, and gradually expands toward the lower part of the leaf. Withered, leaves are usually smaller than normal leaves, plant root growth is inhibited, the new root is short and thick, curved, tip often brown to death, the lack of calcium in the fruit often causes the loss of calcium protection of the pulp cells, resulting in a large range of fruit drop before fruit harvest, fruit day Burning, fruit cracking, and rotten fruit disease occur severely and are not resistant to storage and transportation.

Calcium supplementation method: The commonly used calcium fertilizers in fruit trees are calcium chloride and calcium nitrate. Generally, the application method is foliar spray, and the concentration is 0.3%-0.5%. The absorption of calcium in fruit trees has two peak periods in a year, the first time in the month after flowering. The second time around one month before fruit harvesting, the spraying effect was best at these two peak periods. In addition, the application of organic fertilizer to the orchard, fertilization of the soil or appropriate application of lime and soil acidity, can promote plant absorption and utilization of calcium.
