How to grow jujube in a greenhouse What is the best variety?

Go to this ** and find Mr. Shao.

Introduction: Red dates will often appear in everyone's life, such as throwing a few red dates when stewing soup, the nutritional value will be higher. Not only that, jujube can also be used to make tea, especially for women, it is a very good food, and it has the effect of beauty and beauty, so what kind of conditions can grow jujube with such a wide range of uses?

We all know that plants must have light to photosynthesize during their growth.

The jujube tree is no exception, and its requirements for light are even stricter than those of ordinary plants. Therefore, when planting jujube trees, it must not be too dense and the spacing is relatively large, so that each jujube tree can be fully bathed in the sun, and planting jujube trees on the slope will have better yield and quality than planting jujube trees on flat land, and it is precisely because of the light on the slope that it will fully irradiate every tree. <>

Water is one of the indispensable elements for plant growth, and in the growth process of the jujube tree, it is also necessary to water the jujube tree in a timely manner, although the jujube tree is a relatively drought-tolerant variety, but it still needs the nourishment of water in the growth process, especially in the flowering period, it needs sufficient water to ensure that the flowers are very lush, so that the fruit will be more. Similarly, the jujube tree is also a waterlogging-tolerant fruit tree, even in the south with rainfall.

A lot, this fruit tree can also grow very well, but for some heavy storms.

In the weather, its tolerance is still relatively weak, especially after fruiting, if there is a strong wind in the weather, these fruits will fall to the ground, resulting in a reduced yield. <>

Jujube tree is a drought-tolerant and waterlog-tolerant fruit tree, so its adaptability to the soil is still relatively strong, whether it is dry land or moist and humid land, it can survive very well, for the pH of the soil.

There is no pickiness, so jujube trees will be planted in most parts of our country, and the yield of jujube trees will be very high every year.

Jujube is very adaptable and does not have high requirements for soil, so it can be planted in unfertile land such as wasteland, but the better the soil, water and air, the more conducive to the growth of jujube trees.

First of all, it is necessary to choose the technology of cuttings, the density of planting should be kept at about 6 meters, the depth should be grasped at about three centimeters, and then the temperature should be kept at about 18 degrees to 23 degrees, and it should also be watered and fertilized in time, and it should be planted in plain or hilly areas.

The condition of the land should be very good, the conditions should be very arid, the sun should be very abundant, the soil should be very fertile, and the temperature should be relatively good.

One: the planting season of jujube

The survival rate of jujube trees is best when planted in autumn.

First, jujube trees are planted in autumn for a long time. It can be planted from late October to late November.

Second, the temperature is more suitable. With the gradual decrease of temperature in autumn, the transpiration of jujube after planting gradually weakened, which was more conducive to the survival of seedlings. And because the temperature drops slowly, even if it is planted in late autumn, the physiological activity of the root system can still continue, and there is no major impact on the seedlings in the roots.

The third is the quality of seedlings. Autumn jujube seedlings are all seedlings grown in the nursery, fresh and vibrant. Generally, spring sowing seedlings will not be advanced due to the need for stubble seedlings. Seedlings will not appear in a state of long-term improper storage, decreased vitality or even death.

Fourth, save labor and time. In autumn, due to the high soil moisture, good water content, low temperature, less water evaporation, and less water requirement, the number of watering times can be saved.

2: The variety type of jujube

Jujube mainly includes: moonlight jujube, jujube Cuiwang red jujube, golden silk No. 4 jujube and winter jujube are all jujube tree species. Among them, the fruit shape of moonshine jujube is very peculiar, with pointed heads, and the average weight of a single fruit can reach about 15g.

Zaocuiwang jujube is large, uniform in shape, oval in shape, and has an average single fruit weight. Jinsi No. 4 jujube is an excellent jujube variety selected and bred in the early 1990s, and it has performed well in Sichuan, Yunnan and other places in China.

To sum up: the planting of jujube trees will generally be selected in autumn, the temperature at this time is the most suitable for the growth of jujube trees, and it is also of great benefit to the jujube trees we plant, if you want to plant jujube trees, you can do it in autumn, there are many varieties of jujube trees, rich in variety, jujube is also rich in a lot of nutritional value, it has great benefits for our body, in daily life, we can eat more jujube, it can help us invigorate blood, it is very good for our body, at the same time, Jujubes can also be dried into dried jujubes, so that we can eat them very well later, and it is also very beneficial to our health.

Dates should be planted in the fall. The varieties of jujube include moonlight jujube, winter jujube, golden silk No. 4 jujube, jujube Cuiwang red jujube, Hulu jujube, pear jujube and so on.

It will grow better in the middle of autumn, when it is planted, and the varieties are green jujube, golden silk jujube, gray jujube, Jun jujube, and jade jujube.

Planted in autumn, moonshine bezoars, golden silk bezoars, crisp bezoars, winter jujubes, jujube Cuiwang red jujubes, these are all famous varieties.

Jujube planting conditions.

Jujube trees need the right air humidity when growing, and the watering should be appropriate, and try not to cause water accumulation in the source of celery. And there should be enough light environment during the maintenance period, so that they can grow well. Loose and fertile soil is generally used for planting.

Date palm planting climate.

Dates prefer a warm growing environment. It needs to be kept at a temperature of 15-25 degrees Celsius when growing, which is more suitable for its growth and development.

Date palm planting area.

Jujube trees are usually grown in mountainous areas below 1,700 meters above sea level and are widely cultivated. It is native to China and is also cultivated in Asia, Europe, and the Americas.

Date Tree Planting Time.

Jujube trees are generally planted in spring or autumn. At that time, the climate and environment were relatively suitable for growth, which allowed them to grow well. There must be sufficient light environment during maintenance, and timely watering and fertilization. Jujube.

Benefits of jujube planting.

The planting benefit is still very good, because its demand is still relatively large. If the yield of one mu is about 1,000 catties, and its selling price is 3-5 yuan per mu, then its income is more than 3,000 yuan, and it will increase in the long term.

Jujube planting points.

When jujube trees are planted, they generally choose loose and fertile soil with good drainage, which will grow better. During the maintenance period, the lotus root should be managed with fertilizer and water. It is best to water and top dressing according to the growth situation, and usually have plenty of sun.

1. Site selection. In the process of jujube tree cultivation, the choice of garden site is very important, which will have a direct impact on the cultivation effect. In the process of selecting a garden site, it is necessary to first consider the light conditions, soil, and drainage and irrigation conditions of the place.

Under normal circumstances, jujube trees are more suitable for planting and cultivation in sandy soil, which has good aeration and pH value below. Good irrigation conditions and abundant water sources can lay a good foundation for the growth of jujube trees. In the process of practice, if the jujube tree is planted by ditching, in order to ensure that it has sufficient light, the method of ditching from north to south is usually chosen.

2. Selection of varieties. Taking the Hotan region of southern Xinjiang as an example, the jujube industry in this area is very developed, and there are many types of jujubes, such as Jinling round jujube, Jun jujube, Hetian jujube and so on. In the process of selecting jujube varieties, it is generally necessary to comprehensively consider the climatic conditions, precipitation and topographic conditions of the planting site, so as to provide guarantee for the survival rate of jujube tree cultivation.

3. Application of basal fertilizer. After determining the cultivars and building the jujube orchard, it is generally necessary to fertilize them, so as to provide a superior growth environment for the growth of jujube trees and accelerate their growth and development. In the process of planting jujubes, the fertilizers applied are mainly mixed fertilizers and farmhouse fertilizers.

Planters are required to decompose the fertilizer according to the actual situation, and then apply the annular furrow, so as to greatly improve the soil fertility.

4. Planting. The planting time of jujube trees is usually in the middle of April each year, the relevant planting personnel dig trenches after selecting the planting varieties and determining the planting area, under normal circumstances, the ridge width, ridge height and ditch depth are 30cm, 30cm and 10cm respectively, and the width of the ditch bottom and the ditch mouth of the protective belt should be kept at 100cm and 120cm. At the same time, in the ditch, the depth of the pit should be kept at 80cm, and the diameter should be about 60cm, and then tariffs and fertilization should be carried out in the pit, and red date trees should be planted, and in the process, the row spacing and column spacing of the planting should be kept at about 2m.

5. Seedling quality. The selection of seedlings is also crucial, usually choosing seedlings with stubby internodes and well-developed root systems, while ensuring the purity of the variety. The length of the main root system, the height and thickness of the seedlings should generally be controlled at 30cm, 70cm.

Control the length and number of lateral roots to ensure root integrity.

6. Colonization. Before the jujube trees are planted, they need to be irrigated, and at the same time, the basic principle of "deep digging and potential planting" should be followed to provide them with sufficient organic fertilizer. In the planting process, the treated seedlings need to be placed in the pit, and then tamped, and buried in the soil after ensuring that the root system of the jujube tree is level, and the soil depth is strictly controlled.

In the planting process, the temperature should be kept at about 18, and then it should be dried, and the height should be generally kept at about 60cm, and the cut should be treated and bandaged with plastic film to avoid the problem of water loss.

7. Irrigation. After planting, the trees are watered, and in early May to mid-August, the soil moisture is taken into account, and then the frequency of irrigation is determined. Under normal circumstances, the number of irrigation times should be kept at about 6 times, and the irrigation should be carried out in the evening or early morning.

1. Choose the jujube orchard carefully. Densely planted jujube orchards should be selected in the plains of shelter from the wind and the sun, the terrain is flat, the sunshine is sufficient, and the altitude is below 900 meters, with deep soil, loose texture and fertile soil. Jujube seedlings are not alkali tolerant, so the new land planting jujube trees can not be in a hurry, the first choice should be to introduce fresh water to wash alkali, deepen the ripening of the soil, increase the application of organic fertilizer, deep ploughing to increase the content of soil organic matter.

Heavy clay, gravel soil should be dug and replaced with soil.

2. Land preparation and foundation: dwarf dense planting is the basis for the early yield of jujube trees, which is to select dwarf (short-branch) varieties and take comprehensive measures to obtain bumper yields within 3 to 5 years after planting, so as to continuously improve the quality and yield under the premise of ensuring the healthy growth of the tree. Therefore, land preparation and fertilization is the first condition for the early and abundant yield of jujube trees.

3. Spring planting, in the late autumn of the previous year, the land is fully prepared, ploughed 30 cm deep, and the autumn planting is fully deep in the early autumn. On the basis of comprehensive land preparation, according to the designed plant row spacing, carry out 1 meter square hole-shaped land preparation at the planting point, pile the topsoil and raw soil separately, and lay 15 25 kg of crushed crop straw at the bottom of the pit, mix each pit with 20 30 kg of farm manure and topsoil and fill it in the pit, and finally cover the raw soil with water once to prepare for planting. Adjust the relationship between water, fertilizer, air and heat to maintain a stable environment conducive to the growth of jujube roots.

4. Planting method: Seedling selection must be made of pure varieties, strong growth, complete root system, no jujube diseases and pests and grafted seedlings, and the rootstock and scion are firmly healed first- and second-class seedlings. First-class seedlings:

Height above the meter, the ground diameter is more than centimeter thick, the lateral root thickness is more than 2 mm, the length is more than 20 cm 6 8, the secondary seedling: high meter, the ground diameter is 1 cm, the lateral root is 2 mm thick, 18 cm long, 5 or more.

1. Soil. Jujube trees have strong adaptability to the environment, and the requirements for soil are not particularly strict, as long as they are grown in soil that is not polluted, has good air permeability and drainage, and is moderately fertile. Use garden soil, then add humus and sand.

2. Temperature. The ambient temperature of planting jujube trees should be controlled at about 25 and placed in a cool place for breeding. If the light is too strong, you can use shade netting to protect yourself from the sun.

3. Watering. After planting, the jujube tree should be watered every 3 5 days.

4. Fertilization. After the jujube tree is planted, it needs to be fertilized once every 20 days, and the fertilization is generally nitrogen, phosphorus and potassium fertilizer, or organic fertilizer.
