What about cherry blossoms and fruits?

Cherry planting after falling flowers will certainly reduce the results, but that is why sometimes there will be fruit drop phenomenon, which will bring great losses to fruit growers. Do not have such a phenomenon to learn to understand prevention, if there is such a problem, you can seriously look at the following content, will briefly introduce the reasons for falling flowers and fruits and preventive measures.

First, the reason for falling flowers and fruits

1. Pollination and fertilization

Flowering heavy rain leads to incomplete flower development, imperfection, deformity, loss of style, etc., resulting in inability to fertilize or poor fertilization. Rain Water makes pollen lose vitality, lose pollination, can not complete pollination, pollen loss, adhesion, can not rely on wind pollination.

two。 Malnutrition

Flowering and fruiting requires most of the nutrition, especially nitrogen fertilizer, if the fertilizer is insufficient, the limited nutrition will fall and no longer continue the expansion and development of the ovary. Will not bear fruit, young fruit lack of fertilizer will stop growing, at the same time, there will be physiological flower and fruit drop. Spring shoot growth or summer shoot growth will consume a lot of nutrients, blossom and fruit nutrition will not fall.

3. Improper management

After the spring shoot is harmed by the red spider, it will cause a large area of fallen leaves, or leaf yellowing, can not carry out light and effect, reduced nutrition will drop flowers and fruits. Sunburn is the cause of fruit drop. If you use too much fertilizer, or use a fertilizer with a high concentration of heat, the absorptive capacity will decrease after the accumulation of water and damage to the root for a long time after rain. The growth of the tree is abnormal, the secretion of hormones is out of balance, and the fruit stalk will fall off without the timely use of growth regulators.

II. Solutions

1. Artificial pollination

Pay attention to the weather in real time, collect enough pollen before continuous rain, after no continuous rain, you can carry out artificial pollination in time, do not miss the development time, and increase the fruit setting rate. Rain during flowering can cover cling film to prevent Rain Water from entering the crown.

two。 Supplementary nutrition

Before flowering or after fruit setting, nitrogen fertilizer was applied once respectively to ensure fertilizer supply without lack of nutrition. With the addition of some phosphorus and potassium fertilizer, the male fruit expanded rapidly and was not easy to fall. For physiologically fallen flowers and fruits, gibberellin must be sprayed at this time to protect flowers and fruits.

3. Administration and Management

Do not apply nitrogen fertilizer to make the leaf color thick green lead to insect harm, after being harmed by red spiders, you should timely spray avermectin, triazotin, benzenite and other agents. Fertilizer should be just right every time, not too much, do not apply hot poultry fertilizer. After it rains, it is necessary to supply water and dredge the drainage channel and drain it quickly.

Cherry flower and fruit drop in addition to the lack of fertilizer caused by physiological fruit drop, there are other reasons, according to the symptoms of the tree should be able to determine what is the reason, and then find a suitable way to solve this problem. Our goal will be achieved.
