Peppercorns are grown in the north, how to ensure overwintering?

Sichuan pepper is a seasoning that we often see in our lives, and it is also called Shu pepper and Sichuan pepper.

It is an important cash crop in China.

One. In addition to being used as a seasoning, it is also the main raw material of China's flavors and fragrances, and can also be used to make medicinal materials and wine, which has high planting economic benefits.

The planting range of Zanthoxylum pepper in China is very wide, especially in Guizhou, Sichuan and Chongqing and other areas with high demand, and the planting area is expanding every year. Zanthoxylum pepper tree.

It is a plant with poor cold resistance, and it is often susceptible to frost damage in cold winters. So, how to prevent frost damage from pepper trees? What are the methods? Let's take a look.

1. The trunk is painted white

In winter, the trunk of the pepper tree is whitened with a special trunk whitening agent. It can not only kill overwintering bacteria and insect eggs on the trunk, but also enhance the ability to reflect sunlight, reduce the large change of temperature difference between day and night, and avoid sun burn and night freezing. When drying, try to coat the trunk all over until the branch of the main side branches.

2. Spray protective agents

Use tirobin (or antesen) + Penfol + amino acids.

Foliar fertilizer mixed with water is sprayed on the leaf surface, branches and trunk, which can seal the stomata of the branches, reduce water loss, prevent strip extraction, delay the flowering period of pepper trees, and increase the sap concentration of the tree, thereby enhancing cold resistance.

3. Smoke and cold

At about 11 o'clock in the coldest night, at the corner of the limelight on the pepper garden, sawdust, firewood, chaff, rice husk, dead branches and leaves are used as fuel, covering the dark fire and burning smoke, so that the smoke covers the whole garden. When smoking, you must pay attention to controlling the fire to prevent burns from being too close to the pepper tree.

pepper trees, or a fire.

Fourth, soil cultivation and cold protection

At the base of the trunk, a root protection belt with a diameter of about 1 meter and a height of about 10-20 cm in soil is used to reduce frost damage. In spring, the soil should be removed in time to increase the ground temperature and promote root activity.

5. Cover the tree disk

Mulching the tree tray with straw, corn stalks or weeds can not only retain moisture, but also increase the ground temperature. Laying mulch or leaves, wood chips, etc. within 1 meter around the trunk can increase the ground temperature and prevent frost damage to pepper trees.

6. Winter irrigation and water conservation

When the soil is "frozen at night", dig a trench between the rows of pepper trees, and then irrigate the ditch through the water. It is better to seep out the amount of water before nightfall. It can not only be used in winter and spring, prevent spring drought, promote the growth and development of pepper trees, but also store water temperature and make cold waves.

During this period, the ground temperature remains relatively stable, thereby reducing frost damage. After winter irrigation, it is best to cover the grass, or to hoe the ground surface shallowly to prevent water evaporation.

7. Pruning and shaping

In the early winter, deciduous pepper trees, especially 1-2-year-old deciduous pepper trees, can be properly pruned and broken in time to reduce tree consumption, increase accumulation, and improve the ability to withstand cold and frost.

The above is an introduction to the knowledge of the pepper tree. Whitening of the trunk, spraying of protective agents, fumigation and soil protection, winter irrigation and water retention, pruning and shaping are all common anti-freezing measures in the planting process of Zanthoxylum bungeanum trees. Growers can make reasonable choices according to the actual situation of their own planting areas.

Whitening the trunk is one of our common ways to prevent frost damage, and it is also a method that can be applied to all kinds of tree species.

1. Mulching the tree tray: Covering the tree tray with straw, corn stalks or weeds can not only preserve moisture, but also increase the ground temperature. 2. Winter irrigation and water retention:

When the soil is "frozen at night", dig a ditch between the rows of pepper trees, and then irrigate through the ditch, and the amount of water is better to infiltrate before entering the night, which can not only achieve winter water and spring use, prevent spring drought, promote the growth and development of pepper trees, but also store water temperature, so that the ground temperature remains relatively stable during the cold wave, thereby reducing frost damage.

3. Pruning and shaping: In early winter, deciduous pepper trees, especially 1-2-year-old deciduous pepper trees, can be properly pruned and broken in time to reduce tree consumption, increase accumulation, and improve the ability to keep cold and freeze.

Film can be laid in the ground to keep warm. It can also be wrapped in a tree with straw rope or insulation.

<>1. Zanthoxylum bungeanum has strong cold resistance: Zanthoxylum bungeanum has strong cold resistance, it can be planted in the northeast of China, has a strong survivability, and it can also be drought tolerant, can grow in arid and semi-arid areas, is a plant with strong adaptability, and can be planted in all parts of China.

However, it is necessary to pay attention to (1) tree management. Before entering the winter, we should first whiten the trunk of the pepper water. Whitening the trunk can effectively eliminate the germs and insect eggs that lurk on the trunk for overwintering.

And it also has a strong reflective ability, which can reduce the temperature difference between day and night as much as possible. When painting white, you should repent, paint the whole trunk white, and keep the soil bag in the place where it is forked. At the same time, we can also spray the right amount of protective agent on the leaves, branches and trunks.

For example, amino acid foliar fertilizer, Antaisheng, etc., after spraying, the stomata of the branches can be closed, so as to avoid consuming too much water and causing the phenomenon of striping, and can also delay the flowering period of the pepper tree and enhance its cold resistance. (2) Prune and cover the tree tray. In early winter, we should prune the pepper trees that have fallen their leaves, especially the trees within two years, and do a good job of breaking the tip.

Avoid excessive consumption of the tree, improve the nutrient accumulation in the tree, and enhance the cold resistance of the pepper tree. Then we can also cover the tree tray with straw, corn stalks and other grain straw around the tree tray. It can not only have the effect of preserving moisture, but also increase the ground temperature.

At the same time, Hongcha should lay mulch film or leaves within one meter around the trunk, which can effectively reduce the frost damage of Zanthoxylum bungeanum trees. (3) Winter irrigation and water conservation. After entering the winter, the soil is very prone to the phenomenon of night freezing and diurnalization.

So we should dig a trench between the rows of the pepper tree and pour plenty of water along the ditch. Make sure that the water can fully penetrate the soil before nightfall. In this way, the water we water in the winter can be used in the spring.

Avoiding the phenomenon of spring drought is also very beneficial to the growth and development of pepper water. Moreover, water also has the function of temperature storage, which can ensure the relative balance of ground temperature in winter and reduce frost damage. After winter irrigation, it is necessary to cover the grass in time, and it can be properly shallow hoeing to avoid the rapid evaporation of water.

<> peppercorns can be grown in the north. The time for planting pepper in the north is generally autumn, because the spring in the northern region is still relatively cold, the soil is relatively dry, and the rainfall is not much, so it is better to plant in autumn; If the planted pepper seedlings are older, you can choose to plant them in the early autumn period of August and September, and the younger pepper seedlings can be planted in September and October.

Pay attention to the temperature at the time of planting, you can plant pepper in the north, because if you want to have a large yield of pepper, you need to pay attention to the temperature and humidity during the flowering period to provide an environment suitable for the growth of pepper.

Be sure to ensure that the soil is moist, water it in time, and pay attention to proper ventilation, so as not to have too many germs. It can also be planted in the north.

When the rain came, he was diligent in inspecting the pepper orchard, and found that the stagnant water was immediately discharged from the field. The soil should be a sandy soil with good air permeability and drainage, and should never be cultivated in low-lying areas that are prone to water accumulation. After the land preparation is carried out, the planting holes are excavated according to the plant spacing meters and row spacing meters.

As for the depth of the planting hole, it should be determined according to the length of the seedling. Pepper trees can be grown in the north. Zanthoxylum trees can be grown in the north and are very common.

In the past few years, we have gradually encouraged farmers to diversify the development trend of planting, our town chose the planting of pepper and persimmon trees at that time, and in this year's pepper gradually concluded, and the quality is good, the purchase price of 1 kilogram of dried pepper is about 40 yuan, (I drove to the purchase point) so I think large-scale planting of pepper is completely possible, as far as I know, there are at least 4 towns in the county at this stage are currently the key main production areas of pepper. However, it is very important to consider whether the local weather and soil layer are suitable for the growth and development of Zanthoxylum.

Zanthoxylum pepper belongs to the economic crop, and its price generally fluctuates with the ups and downs of the sales market. Due to the bright prospects of the industry, it has promoted the preparation of farmers to persevere in planting, expanding from a few acres of land to dozens of acres or hundreds of acres. In mountainous areas, there are few plains and many slopes, and generally one mountain is connected to one mountain, and this incomparable environment is the crops belonging to the tree family, especially the pepper.

From the perspective of planting farmers, farmers who are dominated by agriculture and animal husbandry can plant pepper by the way. Due to the pepper tree.

Growth and development do not require a lot of manual careful management.

The planting process is very simple.

From the perspective of capital investment, 80 plants are planted in 1 acre, and the seedlings of this year are yuan. The cost of 1 mu of seedlings is only 200 yuan. From the point of view of technology, the daily management methods are mainly hoeing, chemical fertilizer, chemical fertilizer, and the technical strength is not high.

From the perspective of labor costs, the main reason is that the cost of manual harvesting is relatively high, but the centralized harvesting period is more than 40 days, which can be centralized. From the whole industry chain of commodities.

Seemingly. The production, processing and sales market has a large demand for raw materials. Don't worry about the sales market. Actually, green peppercorns.

The whole body is a treasure, medicine and food are used for both purposes, and the whole industrial chain of commodities can be extended.

At present, the price of pepper in the market is relatively stable, and the demand is relatively stable. As a very common seasoning among the ingredients in our country, the demand for peppercorns is steadily rising due to the continuous improvement of everyone's living conditions, and the price level is relatively strong. Moreover, the demand for pepper in other fields is gradually increasing.

For example, the use of Sichuan pepper to refine Sichuan pepper oil.

Peppercorn noodles and other seasonings, this kind of production and processing of pepper products or very popular at this stage.

Absolutely; Yes, and many people in the north will grow peppercorns, but in winter, you must take relevant cold protection measures.

Of course, it can be planted in a large area, and it is necessary to determine whether it can be planted according to the local climate, and the temperature requirements are relatively high.

Zanthoxylum pepper can be planted in a large area, and it is mostly produced in the north to the southwest of China, so it can be planted in the north.

How to protect pepper seedlings in northern Shaanxi for winter.

If it is a small tree, you can consider moving it indoors, in fact, you can plant it outside, as long as it is not a special year and can safely spend the winter. I've seen other people's pepper trees planted outside.

It does not have to be transplanted indoors.

The pepper tree can safely survive the winter on its own.

Zanthoxylum is distributed from north to southwest China, and is distributed in northern, central and southern China. Yuncheng in Shanxi, Hancheng in Shaanxi (the relationship between geographical location, the taste of Hancheng pepper is the strongest, the most fragrant), Heyang (the largest production area in China), Funiu Mountain in Henan Province, Taihang Mountain, Yiyuan in Shandong Province are more concentrated, due to geographical and climatic reasons, especially the big red robe in the Maqidang area at the top of Taihang Mountain in South China is better, and it is planted everywhere in Yanling. There are some varieties in South America that grow in the wild.

Therefore, Sichuan pepper does not have to be moved indoors.
