How to prevent winter dates and summer fruit drops?

The late white ripening stage of jujube and 10 to 15 days before fruit ripening are sprayed with naphthalene acetic acid or sodium naphthalene acetate, and the concentration is approximately. When spraying, all the fruit surfaces and fruit stalks are required to be medicated. When cultivating in a garden, it is the basis to choose excellent varieties that are not prone to fruit drop (be sure to consult well when purchasing).

With reasonable cultivation measures, what water and fertilizer management, plastic pruning, hoeing and pollination and other common problems, improve the ability of fruit trees to resist fruit drop.

Scientific and rational fertilization to prevent nutritional disorders. Fertilization can not blindly apply a large number of element fertilizers (N, P, K), and at the same time pay attention to the supplement of medium and trace elements, scientific and reasonable fertilization, and promote the normal growth of jujube fruit. At the same time of fertilization, add substances to promote the growth of the root system of the jujube tree, remove germination, topping For the useless jujube head that has just germinated, it can be erased from the base when there is no room for development, leaving only 2-3 jujube hangs at the base.

In this way, the nutrient consumption of the tree can be effectively reduced, and the nutrients can accumulate on the jujube hanging and jujube fruits, thereby accelerating the growth of young fruits.

This disease will only harm the leaves of the plant, in the early stage of the disease, the back of the leaf scattered light green dots, and then gradually become dark yellow-brown irregular protrusions, that is, the summer spore pile of the fungus, the diameter is generally about millimeters, mostly occurs on both sides of the leaf vein control measures: (1) combined with pruning and careful gardening: cut off the remaining jujube hanging, diseased and insect branches and dead branches on the tree, strengthen fertilizer and water management, improve the soil, in late autumn and early winter, each plant applied 50 60 kg of rotted circle manure or human feces, and after the rain in June, each plant was topped with potassium sulfate compound fertilizer 2 3 kg Each pesticide has its best control object, and when carrying out pest control work, pesticides with good control effect, low toxicity and low residue should be selected for control.

Avoid taking the so-called insurance drugs and universal medicines, and do not use the wrong drugs, so as not to cause drug damage.

According to the characteristics of jujube trees that like sunlight, when we choose land for afforestation, we prefer sunny gentle slope land, which has deep soil layer and good soil structure. If it is cultivated on flat ground, it is necessary to pay attention to increasing the gap between the plant spacing and the row spacing to ensure its permeability in a good environment.

Once such a situation occurs, it is necessary to ventilate in time, and to do a good job in water and fertilizer management, but also to strengthen field management, and then also need to water and fertilize in time, and at the same time must be timely weeding and loosening the soil.

It is necessary to pay attention to the control of temperature, but also to control the intensity of light, but also to timely top dressing, timely watering, but also to ensure the humidity of the soil, to pay attention to planting density, but also to timely ventilation.

First of all, we must do a good job in water and fertilizer management, and secondly, we must do a good job in the prevention and control of pests and diseases.

1. Prevent fruit dropping. In order to reduce fruit dropping, we should spray strong fruit pedicle in time to increase the fruit pedicle in the young fruit stage and fruit expansion period to 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.

2. Reasonable top dressing. After the winter jujube is set into fruit, it is necessary to water it in time, and increase the application of compound fertilizer or organic compound fertilizer rich in nitrogen, phosphorus, potassium, iron, boron, calcium, zinc and other large and trace elements necessary for winter jujube. 3. Timely prevention and control of pests and diseases.

The main insect pests in the young fruit stage of winter jujube are peach heartworm, red spider and green blind tsubaki, etc., and special attention should be paid to prevention and control.

Although jujube trees are more resistant to drought, in order to promote their growth and development, adjust the reasonable nutrition and water of the tree, so interlaced irrigation, drip irrigation, ditch irrigation and other measures should be taken, the amount of water is not too large, and the amount of irrigation water is 3 5 kg mu per time. The first irrigation was carried out before the jujube tree germinated, and according to the strength of the tree and the size of the tree, a series of water-soluble fertilizers of Zhongnong Lego nitrogen or high phosphorus were reasonably applied.

The fertilization period of winter jujube is generally divided into two times: the first time is placed after the autumn harvest, with basal fertilizer as the main fertilizer and phosphorus fertilizer at the same time. The second time is placed in the young fruit stage, mainly with chemical fertilizer, and it needs to be reapplied.

In terms of chemical fertilizer types, nitrogen fertilizer and potassium fertilizer are the main fertilizers, and some phosphate fertilizers need to be appropriately applied. Winter jujube flowering and fruit setting consumes a lot of tree nutrients, and various fertilizers must be applied after fruit set, which is the critical period of winter jujube fertilization.

It is recommended to artificially assisted pollination during the flowering period of winter jujube trees to improve the fruit setting rate, and at the same time, spray strong fruit pedicle to thicken the fruit pedicle before flowering, young fruit stage and fruit expansion period of winter jujube tree to improve nutrient delivery.

It is necessary to carry out reasonable fertilization of winter jujube, improve the fruit setting rate, reasonably thin flowers and fruits, and control growth and reduce nutrient consumption through topping, budding, and nutrient consumption, which can improve the photosynthesis of trees and increase nutrients.

Watering and fertilizing more before the winter jujube blooms, watering and fertilizing should be stopped when flowering, increasing the exposure to sunlight, fertilizing more when the flowers fall and fruiting, and pruning the branches and leaves of the winter jujube so as to improve the results of the winter jujube.

Depending on the situation, fertilizer can be applied, and a small amount of hormone can also be used appropriately, so as to maintain sufficient light, sufficient moisture, and maintain appropriate temperature and humidity.

There are many plants that reach their peak in summer, and the same jujube trees are also at their peak in summer. Because the budding of jujube trees is very late, and both flowering and fruiting occur in the summer, if there is no way to take good care of it, it is likely to lead to a phenomenon of little fruiting. Therefore, it is necessary to do a good job in the management of jujube trees in summer, otherwise it will affect the harvest.

First of all, it is very important to learn to prune the branches and leaves, and not let some branches and leaves on the jujube tree grow, otherwise it will absorb a lot of nutrients, resulting in the jujube not having enough nutrients in the growth process. <>

Pruning can start in June, pruning the foliage will promote the second branching. When pruning branches and leaves, you can pluck the topping, you can leave about 5 side branches appropriately, if the space is very small, you can leave about 3. And also to remove some of the inactive sprouts, the presence of these sprouts will absorb a large amount of nutrients, so in the absence of action should be disposed of in time.

If the pledge is too dense for fertilization and watering, it will not only divide away a lot of nutrients, but also block some pledges from getting enough light. In addition to pruning the branches, pay attention to fertilization and watering. Because jujube trees need to consume a lot of water and nutrients when they grow in summer, they must replenish the corresponding water and nutrients in time.

You can add some urea to the soil where the jujube tree is planted, and add a lot of water during the flowering period, otherwise it will affect the growth of the jujube. <>

Proper wateringAlthough jujube trees are very drought-tolerant plants, it does not mean that they do not need water, on the contrary, jujube trees have a very high need for water. If the temperature around the jujube tree reaches 21 degrees Celsius, the humidity needs to be around 60%. But it's also important not to over-water, as overwatering during flowering can lead to some undesirable effects.

Jujube trees need sufficient water throughout the growth cycle, especially during the flowering and fruit development periods, and must be given a good irrigation guarantee. It should be noted that jujube trees should not be watered too much during the flowering period, and the method of frequent watering with small water can be used in drought years, and the effect is also very good.

First of all, it is necessary to strengthen fertilizer and water management, and in the process of fertilization, it is necessary to turn over the pressure, and it must be watered in time, and it is necessary to hoe in time, and it must be pruned in time, and it is necessary to spray hormones in time, and then it is also necessary to control pests and diseases.

It is necessary to top dressing on time, so that it can have a good effect, pay attention to watering, pay attention to top dressing, pay attention to the use of pesticides, these are very important.

With the arrival of summer and autumn, many people believe that the jujube trees planted have already been harvested. In fact, eating more dates also has a lot of benefits, it can replenish blood volume for women, and it is very good for women's bodies. For some elderly people, you can add some red dates to the soup when stewing chicken or pork ribs, which is not only very delicious, but also full of color.

Then when planting jujube trees, you will also encounter a series of problems. Jujube trees are common in summer and autumn, how to prevent jujube trees from falling fruits? <>

1. The reason for fruit drop is that many times the reason for fruit drop is malnutrition, and at this time, it is necessary to let the grower apply more fertilizer to the jujube tree. You need to observe the growth of the jujube tree, and if you find that the fruit drop of the jujube tree is particularly serious, you should take corresponding measures. It may also be the cause of water imbalance, because the jujube tree is particularly large, so people will not make the water evenly distributed in all areas of the jujube tree when watering.

The most important reason is the pest and disease disaster, in summer or autumn, it is the season when pests and diseases have just appeared, so growers should apply some pesticides next to a few, so as to prevent pests and diseases from attacking. <>

Second, measures to prevent fruit drop growers should make a specific analysis of the situation of fruit drop of jujube trees, if it is because of malnutrition, they should add more nutrients next to the jujube trees, so that they can grow strongly. However, if it is because of pests and diseases, it is necessary to spray more pesticides next to the jujube tree, so that it can also prevent fruit dropping, but do not spray too much in the process of pesticide application, because these dates need to be eaten in the stomach. <>

3. Reasonable fertilization Many people do not care about other aspects in order to improve the economic benefits of jujube trees. Therefore, it is hoped that growers must pay attention to reasonable fertilization when planting jujube trees, so that the fruiting rate of jujube trees will be higher, and higher economic benefits will be obtained.

Pick early. Because my jujube trees also drop fruit, I always pick them in advance when they are about to ripen.

Topdressing. Each fruiting tree was applied with "three elements" compound fertilizer jin + "wofengyuan" medium trace element jin and foliar fertilizer spraying. Spray potassium dihydrogen phosphate solution or urea solution once every 7-10 days, 2-3 times in a row.

It can enhance the function of the blade, increase the weight of a single fruit, and improve the quality. Pennaphthalene acetic acid. From early to mid-July, the canopy is sprayed with 15-20 ppm naphthalene acetic acid, once every 15-20 days, for a total of two sprays.

Even in the growth process of jujube trees, we must water and fertilize in time, pay attention to preventing pests and diseases, and prune in time.

In general, planting winter dates in winter may not bear fruit, as they usually begin to bloom and bear fruit in autumn, and are dormant in winter, making them unable to reproduce and grow. However, in the southern region, due to the mild and humid climate, some varieties of winter dates may begin to enter the growth period and flower and bear fruit in winter, but the yield is lower. In addition, if the tree is older, the growth and reproduction capacity of the fruit tree may decrease, resulting in reduced yields.

Therefore, in order to improve the yield and quality of winter jujube, it is usually necessary to cultivate and manage it in a suitable season, including pruning, pest control, and timely fertilization.

Winter dates are a common fruit tree that is generally planted in spring and autumn, and whether it will bear fruit in winter depends mainly on the temperature and tree strength. In winter, the temperature is low, and the soil may freeze, which will cause greater damage to the jujube tree. Therefore, winter planting cannot be carried out when the temperature is low.

In addition, if you choose to plant on a large scale or intensively, it may also lead to a lack of vigor and failure to bear fruit properly.

If the right time and place are chosen, winter planting can also lead to a better fruit harvest. It should be noted that the management of jujube trees in winter also needs to be more careful and meticulous, including timely irrigation, fertilization, and pest control. At the same time, scientific pruning and fruit thinning can also improve the quality and yield of fruits.

In general, planting jujube trees in winter can get better results, but you need to pay attention to the details of time, location, management, and pruning. Only by doing a good job in these aspects can we obtain a certain fruit harvest.

A winter date is a type of jujube that is picked only after it is fully ripe, and it can usually be picked in late autumn to early winter. If you plant winter dates in the winter, you will most likely not get a harvest that year, and the main reasons are:

1.Winter dates are deciduous trees, and they need a dormant period to adjust the balance of substances in their bodies and prepare for the next year's growth and development. If planted in winter, it can disrupt its growth cycle, leading to poor growth or even death.

2.The temperature in winter is low and the sunshine time is short, which is not conducive to the growth and flowering of winter jujubes, and it is difficult to form fruits. Even if fruit is formed, it may not be fully ripe, affecting quality and taste.

Therefore, if you want to grow winter dates, it is best to do so in spring or summer, so that you can make the most of the growing season and improve the yield and quality of the fruit. At the same time, suitable varieties should be selected according to the local climate and soil conditions, and scientific management and conservation should be carried out.
