How to grow chestnuts and where to plant chestnut trees?

1. Preparation of nutrient soil: according to 40 50 parts of yellow clay, 15 20 parts of carbonized chaff, 8 10 parts of humus, 5 8 parts of tung seed wither, take and mix the preparation of nutrient soil, and then spray nutrient soil with 1000 1500 times of 80% wettable powder of Duoling bacteria for disinfection, and load the nutrient soil into the seedling bag after 3 days;

2. Scion selection: select the annual fruiting mother branch with thick growth and full bud eyes as the scion, the scion has 2 or 3 full buds, and then use the grafting knife to cut the lower end of the scion into a wedge-shaped bevel, and the wedge-shaped bevel is cm long;

3. Select sprouts and seedlings anvil: select the sprouts that grow strongly, when the first true leaf is about to appear and the second true leaf appears, cut off the tender shoots of the upper part of the cotyledons, and make a vertical direct incision in the middle of the two cotyledons, and the depth corresponds to the cutting surface of the scion;

4. Grafting: the cut face of the scion is connected to the incision of the seedling anvil, and the joint of the anvil is fixed with a film from bottom to top to obtain grafted seedlings, and then the grafted seedlings are planted in the seedling bag;

5. Seedling: Place the grafted seedlings in a shade shed with a shade degree of 70 80%, control the temperature in the shed to be 25 28, and the humidity to be 70 80%; After the grafted seedlings survive, remove the sprouting tillers on the seedling anvil in time, open both ends of the shade shed at night and cover them back during the day; After 45 days, remove the film used for bundling and grafting seedlings, and spray urea or dipotassium hydrogen phosphate solution once; After 60 days, the grafted seedlings were cultivated under natural light.

1. Soil. The soil is generally at pH and is acidic. Secondly, the soil should be permeable and the drainage should be convenient. Therefore, chestnut trees are suitable for planting in mountainous areas or sandy beaches with sandy soils, and should not be planted in alkaline soils.

2. Sowing. Before planting, the weeds around the planting point should be cleaned up first, with a distance of 5-6m from a pit, and the depth should be dug about the size of the seedling. Generally, it is necessary to loosen the soil during the fruiting period, and a harvester is about 1-2 times.

The chestnut trees need to be cleaned of weeds and maintained before and after each planting. After planting, it is best to dig a drainage ditch around it so that there is no excess moisture.

3. Management. 1.Before entering the pit, about 1 kg of fertilizer needs to be placed at the bottom of the pit, evenly spread, and then covered with 5-10 cm of soil before planting, so as to avoid direct corrosion of the roots of the tree by fertilizer.

After the filling is completed, the surrounding weeds and fallen leaves can be piled up around the chestnut seedlings and composted, and the top dressing is 2-3 times in the later stage, and the time is between budding and fruiting. Fertilizer should also be appropriately matched with a certain amount of farmhouse fertilizer, with a total dosage of about 10-20kg. Chestnut trees require more water, so they need to be watered more every day, generally once every 3 weeks.

When watering, avoid water accumulation in the roots.

2.Chestnut trees have a greater demand for sunlight, and good light time is the guarantee of high-quality chestnuts. A chestnut tree that is too vigorous will cause the chestnuts to become small and stunted, so it is necessary to build some waste branches in moderation.

If there are pests and insects found during the inspection, they should be removed and taken away in time to avoid the spread of the disease. On days when the winter is too cold, it is necessary to add cold protection measures to the chestnut tree.

In the early stage of chestnut planting, it is necessary to strengthen management, and after 2 years of planting, the management can be slowly reduced. Therefore, you must pay attention to the early stage of planting.

I believe that many people have eaten chestnuts, it often appears in people's field of vision as fried chestnuts, with a crisp taste and rich aroma, which is deeply loved by people. But many people only know fried chestnuts, do not know how chestnut trees are planted, the following will give you a specific introduction to the planting management of chestnut trees.

1.Breed selection.

First of all, planting chestnut trees, variety selection is very critical, it is recommended that you choose chestnut tree varieties suitable for the local climate, it is best to have a certain ability to resist diseases and insects, which is more conducive to later growth.

2.Soil requirements.

The chestnut tree does not have strict requirements for the soil, it is very adaptable and can be grown in most parts of our country. Although it prefers moist soil, it is not okay to be too wet, and if the root system is soaked in water for a long time, it is easy to affect the normal development of the tree. It is recommended that before planting, choose a plot with a certain slope and height and slightly acidic soil, and it is not possible to cultivate in low-lying and humid plots.

3.Grow wisely.

In order to improve the quality of chestnut, the planting density must be planned reasonably, an average of 30 40 plants per mu is the best, planting too dense is easy to affect the yield and quality of chestnut.

4.Water and fertilizer management.

Fertilization is an important part of planting chestnut trees, and before cultivating seedlings, it is necessary to dig a pit and put in well-rotted farmhouse manure as the base fertilizer to increase the fertilizer retention capacity of the soil and lay the foundation for the subsequent management of chestnut trees. In terms of moisture, it is necessary to cooperate with fertilization to carry out synchronously, so that the fertilizer and water are sufficient, especially in the 15 days before the chestnut harvest, which is in the fruit expansion period, if there is drought and lack of water, the impact on the fruit is very large.

5.Trim management.

The pruning of chestnut trees is mainly divided into winter pruning and summer pruning, winter pruning refers to the pruning of the period from the fall of leaves to the beginning of flower buds in the spring of the following year, mainly to promote the normal growth of chestnut trees and the formation of female flowers, and the methods include stubbing, thinning, retraction, etc. Summer pruning refers to the pruning of chestnut trees during the budding stage, the main purpose is to enhance the tree vigor and reduce the male flowers, including budding and thinning. When chestnut flowering, due to the large number of flowers, it is necessary to remove some excess inferior flowers and keep intact healthy flowers, generally leaving 1 3 flowers is the most appropriate.

6.Pest and disease management.

Chestnut juice is delicious and pests and diseases are also very fond of it, so it is necessary to pay special attention to the control of pests and diseases when planting chestnut trees. Among them, the most serious insect pests are chestnut toothworms, and the diseases mainly include powdery mildew and anthracnose, so it is recommended that everyone should focus on prevention and take comprehensive control measures to reduce the occurrence of pests and diseases.

Chestnut tree, deciduous tree.

The fruit is called chestnut, and the praline is sweet and can be eaten. The wood is solid, used for construction and utensils, the bark can be used for tanning and dyeing, the garden application of chestnut trees, in the landscaping of various places, chestnut trees are planted as excellent landscape trees, generally for half-crown transplanting.

It is mainly produced in Shandong, Anhui, Jiangsu, Hebei, Henan and other places. Chestnuts, peaches, apricots, plums, and jujubes are called "five fruits".

Except for a few provinces and autonomous regions such as Qinghai, Ningxia, Xinjiang, and Hainan, it is widely distributed in the north and south, ending in the suburbs of Guangzhou in Guangdong and Pingguo County in Guangxi.

In the southeastern part of Yunnan, it crosses the estuary and goes south to the Sapa region of Vietnam. It is found in mountainous areas from flat land to 2800 meters above sea level, and is only cultivated in cultivation.

Growing environment, chestnut trees are light-loving, drought and cold-tolerant, and resistant to sulfur dioxide in the air.

It has strong resistance to harmful gases and strong ability to absorb dust, and can grow in a dry air and humid soil. Avoid standing water. Deep-rooted, strong root system, strong water absorption, fertility absorption, barren resistance, strong adaptability. Parks, gardens, residential quarters.

On both sides of the road, urban greening is quite suitable.

Chestnut trees are suitable for planting in the terrain of low mountains and hills, and the sunshine conditions are also good, and there are more areas distributed in our country, Hubei, Hebei, Shandong and other provinces and cities are the main planting production areas, in addition to Qinghai, Hainan, Xinjiang, Ningxia and other regions, there are also some plantings in other places.

Chestnut trees are mainly distributed in Hubei, Hebei, Shandong and other provinces in China, suitable for planting in the terrain of low mountains and hills, with a large demand for sunlight, and receiving sufficient light during the growth period, the quality and taste of the fruit will be better, on the contrary, the fruit yield is not good. Chestnut trees are light-loving, both cold-tolerant and drought-resistant, resistant to harmful gases such as sulfur dioxide in the air, can grow in an environment where the air is dry and the soil is moist, and the plant has a well-developed root system, strong water absorption and fertility absorption.

Chestnut trees are suitable for planting chestnut trees are suitable for planting in the terrain of low mountains and hills, and the sunshine conditions are also good, in the distribution of more areas in China, Hubei, Hebei, Shandong and other provinces and cities are the main planting production areas, in addition to Qinghai, Hainan, Xinjiang, Ningxia and other regions, there are also some planting in other places.

Due to the high demand for sunlight and the abundant sunlight during the growth period, chestnut trees are suitable for planting in low hilly terrain, and the time is generally planted in spring or autumn every year.

When planting chestnut trees, you need to dig out the mouth of the tree about 30 cm deep, apply potassium sulfate compound fertilizer to it, and then put the seedlings in, the seedling roots can not be in contact with the chemical fertilizer, avoid burning the roots, pay attention to the plastic tube strips must be set after planting in autumn, and play a role in keeping warm.

Chestnut sapling cultivation.

1. Garden selection: Chestnut orchards are generally built in leeward and sunny places, with deep soil layer, fertile soil, soil pH value, moist soil and good drainage. Do not plant in places with heavy soil clay, low humidity and waterlogging, and strong wind.

2. Planting density: The planting density should be determined according to the site conditions, variety characteristics and technical measures. About 33 chestnut orchards can be planted per mu with high management level and fertile land, and 60-110 chestnut orchards can be planted per mu in mountainous and barren land.

3. Selection of pollinating trees: The self-seeding rate of chestnut is very low, so it is necessary to match pollination trees. The flowering period of pollinating trees should be consistent with the main varieties, and the spacing between pollinating trees should not be greater than 20m to ensure effective pollen dissemination

1；The second is that 2-3 varieties are planted in equal rows or in double rows, and each other is pollinator trees.

4. Planting period and method: chestnut can be planted in spring and autumn. Spring planting is generally around 20 days before budding, and autumn planting is mostly after falling leaves to 20 days before freezing.

The planting method depends on the site conditions and density. In chestnut orchards with deep and fertile soil, planting holes are dug when the density is small, and planting ditches (both at a depth of 8ocm) are dug when the density is high. For plots with poor soil quality, shallow soil layer, and poor subsoil hard permeability, it is necessary to dig a 1-meter square hole for planting.

When digging the hole, the bottom topsoil is separated, and 30 kg of organic fertilizer is applied to each plant in the hole, a small amount of phosphate fertilizer is added, and the cooked soil is fully mixed and filled in the hole, and the water is filled with water. The root recovery ability of chestnut seedlings is poor, and too many root injuries are prevented when seedlings emerge.

Chestnut seeds are grown as follows:

1. First of all, before planting chestnuts, you need to choose healthy chestnut seeds, you need to break the shell with a knife, be careful not to hurt the flesh, and then put it in a warm and moist environment to germinate.

2. Then the soil, planting chestnuts needs to choose loose, fertile, and breathable soil, and sufficient fertilizer can be applied to the soil before planting.

3. Finally, plant the processed chestnut seeds in the soil, and then add an appropriate amount of water and fertilizer.

Chestnut

Chestnut alias: Kui chestnut, a dicot plant of the family Chestnut, known as the "king of dried fruits". It is found in Asia, Europe, the Americas, and Africa in the northern hemisphere.

It is single-lobed, elliptic or oblong-elliptic, with hairy teeth on the margins; Monoecious, the male flowers are erect inflorescences, and the female flowers are born in the total bracts alone or severally.

The nuts are encapsulated in dense spikes with total bracts 5 to 11 cm in diameter; The flowering period is from May to June, and the fruit ripening period is from September to October. Chestnut is a tree species that adapts to a wide range of climatic and soil conditions. However, under different climate and soil conditions, their growth and development, the abundance and lack of fruit, and the advantages and disadvantages of varieties are different, and even very different.

As an economically cultivated tree, it is impossible not to consider the choice of conditions such as climate and soil. Chestnut is a light-loving tree species that should not be shaded. In valleys with less than six hours of sunlight per day, the canopy grows erect, with thin leaves and thin branches, and low yields.

During flowering and fruiting, insufficient light can cause physiological fruit drop.
