How long does it take for chestnuts to go from seedling to fruit

Results can be obtained in 2 to 5 years.

Chestnut is a deciduous tree, and the young tree grows vigorously before fruiting, with thick branches and erect trees; After fruiting, the growth gradually slows down, and the crown is semicircular; After entering the full fruiting stage, the growth is gentle, the branches are short, and the crown is round-headed. The leaves are hypertrophied, oblong-elliptic, with serrated edges, and the whole leaf is flattened upwards along the main vein.

grafted on annual rootstocks, the fruiting rate in the second year, grafted on 3-year-old rootstocks, the fruiting rate in the current year; 1 15 hectares of 3-year-old saplings with a yield of kilograms; The yield of 12-year-old trees per hectare is up to kilograms, which is higher than that of red-light chestnut. Sweet and glutinous, the quality is superior, better than the red chestnut. Among them, the vitamin C content was milligrams per 100 grams, the total soluble sugar content was milligrams per 100 grams, and the dry contents of starch, crude protein and crude fat were respectively

24 and. Strong resistance to stress, strong adaptability, in the soil pH value, salt content is less than the conditions, can be planted, and obtain high and stable yield, and less damage to pests and diseases, to rainfall and climate adaptation range.

Generally, after planting, the diameter of about one inch in three years can be grafted with excellent varieties, which can bear fruit in the current year, and bear fruit every year after that, and in general, it can bear fruit in five years.

Three to five years, depending on the soil quality and climatic conditions.

The amount of dust that can grow in a year varies depending on a number of factors.

According to Yuda Sogou Encyclopedia, generally speaking, the growth rate of chestnut seedlings in the first year is relatively slow, generally growing about 1-2 inches (about centimeters). Over the next few years, the growth rate gradually increases until it reaches the height of an adult tree. Chestnut trees can typically grow up to 20-30 feet (about 6-9 meters) tall, and some varieties can even grow to more than 40 feet (about 12 meters).

It is important to note that the growth rate and height of the Paiyan chestnut tree are not the only criteria, the number of branches and the development of the canopy morphology are also important factors. Therefore, when planting chestnut seedlings, it is necessary to make appropriate adjustments according to the actual situation, such as pruning, watering, fertilizing, etc., to promote the healthy growth and development of the seedlings.

Planting method 1, soil: the soil used for planting must be selected well, the drainage performance of the cultivation soil must be good, and it is recommended to use sandy soil for planting. It is very afraid of waterlogging, and if the soil is poorly drained, it is very bad for the growth of saplings.

2. Seedling selection: The purchased seedlings will also affect the survival rate, if the seedlings are very thin, then its survival rate will be very low. The seedlings used for planting must be stout and must not have traces of pests and diseases.

3. Planting: When planting, there should be a certain distance before each sapling, not too close, bury the soil around the sapling and press it.

Chestnut sowing needs to be sown on the ridge, and the ditch is about 10 cm wide and about 10 cm deep; Spread the bottom fertilizer, generally with diammonium or compound fertilizer, and then level it with your feet; Spread the seeds in the ditch, the distance of the seeds is about 20 cm, put the seeds flat, cover the soil about 5 cm, and compact. Chestnuts should be planted in sandy loam soils with low water levels and good drainage. When planting, it should be based on local breeding of excellent varieties, such as Gun Truck No. 2, Chenguo No. 1, etc., and Shifeng, Jinfeng, Haifeng and other varieties can also be appropriately introduced.

Chestnut trees rely mainly on wind to disperse pollen, so new chestnut orchards must be formulated with 10% pollinators. The base fertilizer of chestnuts should be mainly soil miscellaneous fertilizer, which can improve the soil and improve the fertilizer and water retention capacity of the soil.

Chestnut planting technology (1) The soil for chestnut planting should choose sandy soil with low groundwater level and good drainage. If you plant chestnuts in hilly land, you should choose a gentle terrain and a thick soil layer near the mountains. (2) The varieties of chestnuts must be excellent, such as No. 2 Gun Carriage, No. 1 Chenguo, etc., and Shifeng, Jinfeng, Haifeng, Qingmao Soft Thorn, Chuxiahong and other varieties can be appropriately introduced.

Moreover, according to different edible requirements, the planting should be mainly based on fried chestnut varieties and appropriate planting of vegetable chestnut varieties. (3) Chestnut trees mainly rely on wind to spread pollen, but chestnut trees have male and female flowers and self-flowering images, so too single varieties will produce empty buds due to poor pollination, so 10% pollinator trees must be prepared when building chestnut orchards.

Chestnut seedlings can be sown before germination in spring and after the beginning of autumn in autumn, in mid-to-late March in spring and mid-to-late August in autumn.

Chestnut grows in most areas of northern and southern China, and has strong adaptability to temperature, and grows in an environment with an average temperature of 10 degrees to 20 degrees throughout the year. Chestnut is sensitive to water requirements, the most avoid waterlogging, poor soil drainage, often waterlogged, will cause the roots of chestnut tree to rot. In terms of soil, it is more suitable for loose and fertile slightly acidic soils.

Planting chestnut seedlings need to dig a large pit for planting, the depth of the pit is 50 cm, the width is 30-50 cm, and the cm is loaded into humus soil such as humus soil or forest soil, and can also be applied to decomposing farmhouse fertilizer, soil miscellaneous fertilizer and organic fertilizer to ensure that the soil is loose and has high organic matter content, which can play a role in retaining water and fertilizer, promoting root development, etc., which is conducive to rapid gardening. In boron-deficient areas, about 10 grams of boron fertilizer are applied to each hole.

The planting density of chestnut is generally 30-60 plants, the planting density of mountain is 50-60 plants, 30-40 plants on flat land, and 120 plants can be planted densely.

The best time to plant chestnut seedlings is in spring and autumn, before germination in spring and after the beginning of autumn. It is best not to plant after the freeze, which will affect the survival of the sapling. The planting time is also different in different regions, so it can be appropriately advanced or postponed for a period of time.

Prepare well-drained soil before planting, and the saplings should be strong enough to bury the soil after planting.

First, the planting time of chestnut

Chestnuts can be sown before germination in spring and after the beginning of autumn in autumn, in spring that is, in mid to late March, and in autumn in mid to late August. It should be noted that it can not be planted after freezing, which will greatly reduce the survival rate, and the planting time is different in different areas, which can be appropriately advanced or postponed for a period of time, and under normal circumstances, as long as it is not particularly cold, it can be planted.

Second, chestnut management technology

1. Root development.

Chestnut is a deep-rooted tree species, with about 80%-90% of its root system distributed in soil above 60 cm. The distribution of vertical roots can reach less than 1m, and the horizontal distribution of roots is wider, generally more than 2 times the diameter of the crown, and the main absorption is mostly distributed in the 1 2 of the root crown to a little farther away from the outer part of the canopy.

2. Fruit development.

After fertilization of female flowers, the initial growth of young fruits is stunted and the growth is small, mainly due to the formation of total bracts. When the new shoots stopped growing, a large number of nutrients accumulated by leaf assimilation began to shift to the fruit, and the young fruit began to grow rapidly, and the fruit grew rapidly in the first month of ripening.

3. Moisture. Although the northern chestnut is more drought resistant, it still has certain requirements for water during the growth period. Appropriate amount of water can be provided during the growth period of new shoots and fruits, which can improve the quality of shoots and fruit size. Although the southern chestnut is more drought-tolerant, in rainy seasons or years, it is still necessary to pay attention to drainage and flood prevention.

3. Soil. The thumb is the granite, gneiss and other differentiated gravel soil, and the sandy loam soil is the best. In recent years, studies at home and abroad have proved that chestnut is a acid-loving and calcium-needing plant, which can be appropriately supplemented with marine food chelating calcium fertilizer, and will not antagonize with other products.

Soil pH value does not directly cause damage to chestnut trees, which are manganese plants, and their leaf manganese content (0,358%) ranks first among many fruit trees (persimmon, peach, walnut, pear, etc.).

There are two best times to plant chestnut seedlings: one is after the leaves fall in autumn and before the ground freezes. Second, after the soil thaws in spring, seedlings are planted before germination.

The best time to plant chestnut seedlings is 10-15 days before germination in spring, when the ground temperature rises to more than 12, generally around the beginning to mid-March. The specific time is based on whether the chestnut seedlings in the nursery are awakened, and has nothing to do with the climate of the planting place. Chestnut seedlings germinate later in alpine mountains, and chestnut seedlings germinate earlier in areas at lower altitudes.

It is best to choose chestnut seedlings in alpine mountains, and the planting time is to buy chestnut seedlings after the chestnut trees in the planting place begin to germinate, and plant them in time.

Chestnut seedlings can be planted in spring and autumn, before germination in spring and after the beginning of autumn in autumn. It should be noted that after freezing, do not plant again, which will greatly reduce the survival rate.

It is best to plant chestnut seedlings from April to May every year, because the survival rate at this time is very high, if you plant it later, it will slow down the seedlings, and it is not easy to survive.

Chestnut tree. What is the growth cycle?

Chestnuts are planted on chestnuts. The main chestnut producing areas in China include Hebei, Shandong, Henan, Jiangsu, Anhui, Hubei, Zhejiang, Guangxi, Guizhou and other provinces. It is highly adaptable to its environment. It can be planted flat or at an altitude of 2,800 meters. Chestnut growth cycle.

<> chestnuts will bud in early May and late May to early June, entering the flowering period. From September to October, they slowly mature and then descend naturally. You have to tap lightly again to fall.

There is a prickly shell on the outside, be careful when picking. The growth cycle of chestnut is about 3 months, and it matures in September and October every year. Chestnut growth rate, chestnut is extracted from the tip of the female fruit branch, mainly experiencing filament shedding, filament widening, anthers.

There are four stages of dehiscence and wilting. The flowering period is about 15 days.

It takes 3 months for chestnut trees to mature from female pollination to fruit ripening. Chestnut growth cycle management, a mature chestnut produces one-fifth of each year, planting 60 plants, and yielding about 400 kg. Temperature Management:

Chestnuts prefer a warm environment and adapt to temperatures of 15 degrees, and too cold or too hot will affect the growth of chestnuts, resulting in a decrease in yield. Fertilization management: Chestnuts can be planted with basal fertilizers.

During the growing season, it is necessary to cover and fertilize in time. Nutrient-balanced compound fertilizer is mainly used.

Chestnut planting should be done on sandy land with low groundwater level and good drainage. The selection of varieties should not be neglected, and local high-quality varieties should be selected for main planting.

Chestnuts mainly spread pollen by wind. However, due to the mixed flowering and self-flowering characteristics of chestnut, this condition can easily lead to empty bracts.

Pollination is poor, and it is best to prepare 10% pollinated trees when planting.

Usually chestnuts are needed after plantingBreedingIt takes 3-5 years to harvest the fruit, which means that the previous years are completely a stage of input, and some haveExperienceof farmers say that the cost of planting one acre is usually 7,000and moreYuan.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Generally speaking, chestnuts are propagated by sowing or grafting. Seedlings begin to flower and bear fruit in about 6 years, late flowering and low yield, and 2 to 3 years old seedlings are commonly used as rootstocks in production, and grafted before and after leaf development. It will be around 20 years to enter the peak period of fruiting.

The planting should not be too deep, and it is better to expose the root neck of the seedling. Timely pest control.

Generally speaking, it takes 5 years to produce chestnuts, and they grow in very tall places and love the sun. If it is a grafted chestnut tree, it will basically start bearing fruit in two or three years.

Chestnuts are planted for two years, and by the time they are three years old, they will bear fruit. During the planting period, it must be watered with more water and potassium fertilizer, so that the yield of planted chestnuts will be particularly high.

The best time to plant chestnut seedlings is around late March, when the chestnut harvest is best and it is also conducive to growth.

The best time to plant is in late March. This is the best time to grow chestnuts that are very tasty.

It should be in the spring, after March and a half, you can start planting, choose a place that is easier to ventilate, and the soil is as fertile as possible.

Grafted chestnut trees begin in 2-3 years.

As a result, the tree bears fruit in 5-8 years. It will be around 20 years to enter the peak period of fruiting.

The grafted tree of improved varieties generally bears fruit in 3-5 years, and the actual tree takes more than 6 years, and it depends on the management after planting.

The appropriate sowing period is in mid and late March (around the vernal equinox), when the ground temperature is above 12.

Sowing too early, low ground temperature, poor growth, long management period.

Sowing too late, the seeds germinate a lot and are long, which is easy to cause losses.

The extended chestnut tree is a 20-meter-tall tree with dark gray bark, irregular deep fissures, longitudinal furrows, and many yellowish-gray circular pores on the bark. DBH 80 cm, winter buds about 5 mm long, branchlets greyish-brown, pedicels oblong, 10-15 mm long, sparsely hairy and scaly glands. Chestnut is a kind of sweet fruit, according to records BC chestnut tree has been widely cultivated in our country, early for the people to eat.

The production areas of Tianjin Ganli are concentrated in Xiaogang, Xiaoying and other townships in Jixian County. In fact, in the mountainous areas of Beijing, Tangshan, Chengde and other places, a large number of chestnut trees also grow, the chestnuts produced, the quality is excellent, because the chestnuts produced in these areas have been exported by Tianjin port in the past, so the name Tianjin Ganli (in Japan, called "Tianjin chestnut"), mainly exported to Japan, Australia, the Philippines, Thailand, Singapore, Hong Kong and Macao and other places. The best chestnut in the country grows in Luotian County, Hubei Province, and the locals call it "Da Hong Pao".

Because its regional sunlight and rain are the most suitable for the growth of chestnut trees, the varieties are particularly excellent, and most of its floor chestnut trees are 100-year-old natural trees, and the fruits are sweet and delicious, but due to the limited yield, there is very little outflow.
