When the jujube tree blooms in the season, the flowering is particularly serious, what should I do?

What are the reasons for the fall of jujube trees in our local jujube orchard, because the root system of jujube trees is very late, the growth period is short, and the flowering amount is large, the flowering period is long, coupled with the uneven distribution of nutrients, it is easy to lead to serious jujube tree flower and fruit fall, in the jujube orchard in North China, there are two obvious flower and fruit drops, the first flower fall is about 1 week after the full flowering period, and the second flower fall is about 10 days at the end of the full flowering period, if you look at it from the whole year, The peak period of jujube tree flower and fruit drop is about mid to late June to early July every year, and in late July, it has entered the second fruit drop peak, and the natural fruit setting rate is often only 1.

Every spring, in the budding, flowering and young fruit stages of jujube trees, fast-acting nitrogen fertilizer should be appropriately applied to ensure the growth of the tree and the nutritional needs of flowers and fruits.

First of all, it is necessary to see if there is a pest, and if there is indeed a pest, it is necessary to use the corresponding anthelmintic medicine for insect control. If it's just a matter of breed, you don't have to worry too much.

The most common reason is that the tree is too vigorous, which is likely to be overnutrition, too vigorous growth, too vigorous branches and leaves, which will cause the jujube tree to consume too much nutrients, difficult to enter reproductive growth, or no nutritional support after entering reproductive growth.

The second reason may be because of the high temperature and drought weather, if there is high temperature and drought weather during flowering and fruiting, it may affect the survival of pollen and the success rate of pollination.

The third possibility is that pollinator trees are not sufficiently formulated, which will lead to poor pollination and failure to bear fruit. In the end, it may be because of rainy flowering and rainy days, pollen absorbs water and splits, and death cannot be fertilized.

Jujube trees that bloom and do not bear jujube require fertilization, pruning, and artificial pollination.

1. The flowering and fruiting of the jujube tree may be due to excess nutrients, which leads to the excessive growth of the branches and leaves of the jujube tree, which consumes a lot of nutrients and makes it difficult for the jujube tree to bear fruit. At this time, it is necessary to reduce the frequency of fertilization, and each time fertilizer is applied, the fertilizer needs to be diluted with water before watering.

2. The flowering of jujube trees may also be caused by the lack of pruning, the growth of jujube trees is very rapid, if not pruned in time during the growth period, it will lead to the growth of jujube branches and do not bear fruit. At this time, it is necessary to immediately prune off the long branches, dense branches, weak branches and dead branches on the jujube tree, so that the jujube tree can bloom and bear fruit smoothly.

3. When jujube trees are subjected to continuous high temperature or rainy weather during flowering, the success rate of pollen pollination will be reduced, resulting in the condition that jujube trees do not bear fruit. In this case, manual pollination is required, and a brush can be used to apply the pollen dots of the stamens to the female flowers.

Field management of date palms

Nowadays, people who grow jujube trees are paying more and more attention to chemical fertilizers, and gradually even no longer use organic fertilizers. In fact, this kind of square bark early style is not very good for the development of jujube trees. Long-term application of chemical fertilizers can lead to a decrease in fruit yield and quality.

Therefore, organic fertilizer is the main fertilizer, supplemented by chemical fertilizer is the best way to achieve uniform utilization of fertilizer. Organic fertilizers are still readily available today. Don't skimp on the money.

Organic fertilizers are cheap. Long-term use can also improve the fruiting period of jujube trees to a certain extent.

Jujube tree diseases and insect pests are relatively easy to occur, but because the initial onset of some diseases is not very obvious, more and more people have begun to pay attention to the problem of pests, which means that the prevention and control of some diseases are not in place at that time, and the frequency of diseases is getting higher and higher. Diseases are no more harmful than insects, so we should pay more attention to diseases so as not to be caught off guard.

In normal growth, the jujube tree is to bloom, and it will only set fruit after the flower blooms.

First, the flowering period of three sprays in the full flowering period that is, 60 when the flowers open, choose a sunny and windless day before 10 o'clock in the morning or evening, evenly spray water to the jujube flowers, every 2 3 days, spray 2 3 times, can improve the fruit setting rate of about 40.

2. Reasonable pruning Jujube tree pruning is mainly based on thinning, and the combination of truncation and shrinkage. Dredging dense branches, removing cross branches, cutting off drooping branches, compressing excessively tall branches, light retraction of strong trees, retraction of weak trees, appropriate removal of old branches for old trees, and pruning of young trees around shaping.

3. Timely opening of the nail Opening the nail is annular peeling. It should be carried out when the jujube tree flowers are one-third open, and the nails should be opened at thirty or forty centimeters from the ground, with an opening width of 0 5 0 7 cm and a depth of xylem, but not to hurt the xylem cambium.

4. Fertilization and watering Jujube trees need water and fertilizer in the early and late flowering periods. Generally, each adult tree is sprayed with 15 kg of cake fertilizer and 1 kg of ammonium bicarbonate or 50 kg of human feces at the early flowering stage, and 1 kg of urea or 1 kg of compound fertilizer is applied at the end of flowering.

That date tree must be wild! Hey, hey......

It should be caused by malnutrition, and it is recommended that you spray Zhuangguo Tilin before flowering, young fruit stage, and fruit expansion period of jujube trees: thicken the fruit pedicle and improve the amount of nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits, so that the fruits are beautifully colored, beautiful in shape, and in good taste.

At the same time, with the spraying of 800 times of the new high-lipid film, it can play the role of liquid film bagging, which will not affect fruit respiration, prevent fruit rust, prevent fruit cracking, improve the coloring and brightness of the fruit surface, reduce residual toxicity and improve quality.

Is that your family in that place?

There are 2 reasons: 1 Maybe it's a male tree, 2 Maybe you don't have enough nutrients under the tree.
