Recently caught four fruit trees can increase production

For apples, grapes, citrus, cherries, peaches, the difference between the south and the north, the sheds are different from the open-air, and the details of each fruit management are different, so here are only the main points, each fruit tree The management method should still be based on the temperature, age, and stage of each place.

1. Watering has doorways. In the case of ensuring the growth of fruit trees, reasonable moisture control adjustments are made according to the rainfall conditions. It is not advisable to use well water. The flowering period of the fruit tree is gradually rising, and the root system of the fruit tree has entered the normal growth state. At this time, if the well water is poured into the fruit tree, the root system is subjected to external stimulation because the groundwater temperature is lower than the temperature of the upper layer, causing the nutrient supply in the tree to be disordered. Physiological dysfunction, it is easy to cause unpollinated flowers and fruitless results.

Note: Do not blindly water, do not be in the crowd. It is important to observe the state of your own fruit trees.

2. Fertilization should be controlled. According to the previous year's tree potential, the use of base fertilizer, and the use of germination fertilizer, balanced fertilization was carried out. Should not be excessive, lack of supplements.

In many orchards, excessive fertilization is common, resulting in soil nutrient imbalance. In particular, the orchard, which has been used for a large amount of chicken manure for many years, tends to cause excessive accumulation of phosphorus in the soil, antagonizing the absorption of trace elements such as iron, zinc and manganese, causing symptoms of deficiency of fruit trees and fruits, affecting tree growth and fruit quality. Therefore, it is necessary to carry out balanced fertilization according to the fertilizer requirement of fruit trees.

Note: Balance fertilization and apply balanced fertilizer. Organic fertilizer must be fermented before use. Unfermented organic fertilizer will damage roots and burn roots.

3, disease prevention is the key. The flowering period is the initial infection period of the disease throughout the year. The temperature rise, germination and leaf spreading provide a suitable and sufficient food for the pests. In addition to paying attention to the protection and treatment of the spray before the rain, it is also necessary. Clearly remember what pests and diseases have occurred in the past, remember what medicines have been used before, then try to alternate and use them the next time you take the medicine. Always pay attention to the recent weather forecast and the actual situation of your own orchard, to decide the timing of spraying, rather than dare to push the day two days in advance, once you miss the opportunity to spray, the future pests and diseases will be hard to prevent.

Note: Prevention is the key, and the disease prevention is good at the flowering stage. The disease in the whole year can be reduced by at least 80%.

4, the frost has to be prevented. Last year's frost caused most of the northern fruit trees to suffer varying degrees of damage. Therefore, preventing frost is very important.

Note: When the night frost is heavy frost, effective measures should be taken to save it. Every effort should be made to protect the fruits remaining on the tree, to grow and grow, to achieve high quality fruit standards, to sell a good price, and to reduce the damage caused by frost. To a minimum.
