How should chestnut seedlings be planted? How to plant chestnut seeds

Fresh chestnuts can be planted by digging holes and watering them.

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.

The steps for growing chestnut seedlings are as follows:

1. The key to seed treatment is moisturizing, low temperature and aeration, and when the soil temperature reaches more than 12 degrees Celsius, it is the appropriate sowing time;

2. After sowing, pay attention to rodent prevention and avoid harm, and after the emergence of seedlings, timely irrigation, loosening soil, weeding and prevention and control of beetle and blight, powdery mildew and other pests and diseases;

3. Chestnut has a wide range of adaptation to climate and soil conditions, and its suitable annual average temperature is to Celsius, if the temperature is too high and the hibernation is insufficient, it will lead to stunted growth and development, and the temperature is too low to make chestnut suffer from frost damage.

There are many varieties of nuts, and the most common of them is definitely chestnut, which has a large market demand. In recent years, the area of chestnut planting in China has gradually increased, so what are the key points and precautions for chestnut tree planting? Let's take a look.

1.Reasonable intercropping.

The growth cycle of chestnut is relatively long, so in order to improve the income, you can carry out some reasonable intercropping between chestnut trees, and many people will generally choose intercropping peas, peanuts, etc. After two to three years of chestnut planting, the planting density of the intercropping crops should be slowly started until it is stopped.

2.Loosen the soil and expand the holes.

Chestnut planting after the autumn of the year need to loosen the soil, the depth of the loosening soil can not be less than 30 centimeters, when loosening the soil, it is also necessary to loosen the soil according to the distribution of the root system of the chestnut tree, the distribution is shallow, and the distribution can be appropriately shallow. Otherwise, you can plough deeply. When loosening the soil, you should remember to pick out the stones and then apply the bottom fertilizer.

After three years of planting, the planting hole can be appropriately expanded, generally at least about 50 cm to the surrounding area. Pay attention to the root system of the chestnut tree when expanding the burrow, and do not dig it up.

3.Water and fertilizer management.

Chestnuts are adaptable, but if you want to achieve a good yield, you still have to ensure that you have adequate nutrition. Therefore, when we plant, we should not only choose fertile soil, but also do a good job of topdressing, and the number of topdressing should not be less than twice a year during the planting process. And it is necessary to reasonably distribute the nutrients in the fertilizer to ensure that the nutrition is adequate and comprehensive.

When the soil is too dry, it should be watered in time, but it should be mainly irrigated with small water, and the water should not be excessive, and it is necessary to pay attention to drainage when there is too much water or rainy days.

4.Cultivating and weeding.

Cultivating and weeding is very important for the growth and development of chestnut trees, because when the chestnut is young, the root ability is not developed enough, the nutrient absorption is weak, and the threat of weeds is greater. Therefore, in the growth of chestnut trees, it is necessary to carry out weeding work at least twice a year, which can not only effectively weed, but also improve the permeability and moisture retention ability of the soil. Promote the respiration and nutrient absorption of the roots, pay attention not to hurt the roots when weeding, and pay attention to the dosage when using herbicides to prevent the impact on chestnut trees.

The weed can be turned into the soil as green manure.

5.Pay attention to the main points.

The growth cycle of chestnut trees is relatively long, but it can be harvested continuously for many years when planted at a time, and the economic value is quite high. Therefore, in order to maximize the utilization value of chestnut trees, we should reasonably master the planting technology of chestnut trees, and we also need to be patient and careful.

Chestnut seedling technology:

1.Nursery plot selection.

Select soil pH value 6, irrigation conditions, well-drained fertile sandy loam soil for nursery land, first deep ploughing of the land, about 3500 kg of bottom fertilizer per mu; Then make a wide meter, 5 10 meters long furrow, 2 days before sowing proper watering, to ensure that the seedlings are unearthed normally.

2.Sow seeds.

Select strong chestnut fruits that have been treated with sand, full grains, free of diseases and pests, and have grown adventitious roots of 1 cm, and erase the adventitious roots from the base to promote the growth of lateral roots. The sowing time is in mid to early March, after the soil is thawed, open a 4 5 cm deep sowing furrow in the furrow, the row spacing is 35 cm, the plant spacing is 15 cm, the seeds are placed flat in the ditch, with the foot firm, covered with soil 3 4 cm and then suppressed, and evenly sprayed on the furrow surface 50% acetochlor herbicide 400 times liquid, and finally covered with mulch.

3.Seedling management.

After the seedlings are unearthed, the mulch film is pierced with 1 hole to expose the seedlings outside the film. 3 When 4 true leaves, spray 75% carbendazim 800 times to prevent chestnut blight. In early to mid-May, when the seedlings are 10 cm high, use a wooden stick to pierce a 10 cm deep hole between the two seedlings, and apply 2 grams of nitrogen, phosphorus and potassium compound fertilizer.

When the seedling height is 20 cm, the topping is carried out, and the potassium dihydrogen phosphate is sprayed at the same time to promote the thickening growth of the seedling.

The propagation mode of chestnut mainly includes two methods of seed sowing and grafting, and the way of seed sowing is mainly to cultivate the rootstock used for grafting, because the fruiting time of chestnut seedlings is longer, and the excellent traits of the fruit are difficult to retain, but the life span of the seedlings is very long, and the stress resistance is also better, which is more suitable for the use of rootstocks. The grafted seedlings are better, which can well retain the excellent traits of the female parent, and the fruiting time is early, the yield is high, and it is more suitable for orchard planting. The cultivation time of chestnut rootstock is generally carried out in the spring and autumn of each year, and the specific time needs to be determined according to the local climate characteristics, the spring is generally carried out before and after the Qingming Festival, and the autumn is planted before and after the beginning of winter.

Cultivation of chestnut rootstocks.

The first is the selection of chestnut rootstock seeds, the seeds of chestnut rootstock need to be suitable for the local climate and environment to grow, strong resistance to stress, the fruit is two big, and the fruit is harvested after natural ripening. After the seeds are harvested, they need to be stored properly, and they can be stored in sand, tanks, cellars, and trenches. Nursery plots need to be well drained and disinfected.

Seeding can be done in a direct way. Use 60 to 85 kg of seeds per mu, put two large or three seeds in each hole, and then cover about 5 cm of soil and cover with mulch. When the seeds germinate, the mulch film is pierced in time.

When the seeds grow to about 10 cm, top dressing should be carried out in time, each plant should use 2 grams of compound fertilizer, and potassium dihydrogen phosphate solution can be appropriately sprayed as foliar fertilizer when the seedlings grow to 20 cm.

Grafting of chestnut seedlings.

Grafting can be carried out when the rootstock grows to a diameter of more than 1 cm and a plant height of about 80 cm. The scion needs to be selected about 30 days before the grafting work. It needs to be carried out before the chestnut tree germinates, and the annual branches on the high-quality chestnut tree are selected, the length of the cut is about 15 cm, and there need to be two to three full bud points.

Then the selected scion branches are stored in the cellar, which can be buried in wet river sand, and the temperature is controlled at about 3 degrees.

The time of grafting should be determined according to the selection of grafting method and local climate and environment. The grafting method can be cleaved, budded, inserted and ventral grafted. After the grafting work is completed, the management of seedlings should be done.

Summary. Hello dear, chestnut trees are generally sown in the spring of each year, and the most suitable time is in March and early April. At this time, the temperature has warmed up, and it is the season for chestnut trees to grow, which is suitable for planting in the mountains or on sandy beaches.

So what chestnut trees need is sandy soil with good water permeability and air permeability. Acidic soil with pH value is better, and chestnut trees should not be planted on alkaline soil. Generally, the sowing methods of chestnut trees are divided into cuttings and seed sowing.

Most people choose the cuttings method, which involves digging out the soil where it needs to be planted and digging a pit. Place the cuttings in the pit, put an appropriate amount of organic fertilizer, and then backfill the topsoil. Pour some water on it and you're good to go.

Dear, here is a way to provide you with chestnut maintenance, I hope it can help you. Water: It is a plant that needs a lot of water, so it should be watered frequently, about twice a week.

Especially in autumn and winter, the high water absorption of plants will be more drought, at this time should be watered twice more to avoid the phenomenon of drought, and sufficient water supplementation is more beneficial to its development. Nutrients: Nitrogen fertilizer and potassium fertilizer are generally used for fertilization, and two additional fertilizers can provide sufficient nutrients.

Light: It likes strong light and is suitable for raising in a full-sun environment. Adequate light absorption can make it grow more robust.

Chestnut planting method:

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.
