The cultivation method of toon, how to plant toon

I have planted 2,000 toon saplings per acre, with a ground diameter of about 2 centimeters. Which type of management is best?

The planting method of the four-season toon: suitable soil, sufficient moisture, sufficient light, and reasonable fertilization.

1.Because the germination rate of toon seeds is very low, before sowing, the seeds should be placed in 30 35 warm water and removed after 24 hours. Place at 25 degrees Celsius for germination.

In Shanghai, seeds are usually sown in early to mid-March, until the radicle has grown to the size of a rice grain (the soil temperature is as low as 5 degrees Celsius at the time of sowing). After seedlings, seedlings are thinned at 2 3 true leaves, and 4 5 true leaves with rows spaced 25x15 cm.

2.Before sowing, germination is carried out with hot water, which can improve the survival rate of the seeds. The seeds are sprinkled in the soil and then covered with a two-centimeter thick layer of soil to moisten the soil and germinate after a week.

3.Choose high-quality toons with red and yellow color, full grains and high germination rate. Soak in warm water for 12 hours at 20 30, then take out the seeds, rinse them with warm water, and then put them in the bag to promote germination, maintain a temperature of about 25, and wait for the seeds to germinate, and then sprinkle the seeds evenly in the planting ditch, and then water with water, cover the soil, cover the soil, cover the thickness of the layer by centimeters, and then transplant when the toon seedlings grow 5 leaves.

The seeds are washed and soaked, wrapped in a cloth for shading and germination, and then planted in perlite. When soaking seeds, they should be washed with warm water every day, and they can be sown after soaking for about 4 days. When sowing, you can put a layer of paper and then spread centimeter-thick perlite, and after sowing the seeds, spread centimeter-thick perlite on the seeds and moisten them with water.

After sowing, the temperature should be maintained at around 20 degrees Celsius. When the seedlings have 4-6 leaves, a small amount of water can be sprayed daily to maintain humidity. Harvesting can be performed when the hypocotyl of the seed bud grows to more than 10 cm.

Toon buds are rich in vitamins and calcium. Phosphorus, protein, etc., can be used to make a variety of dishes.

1. Plant seedlingsToon seeds are small, the seed coat is hard, the membrane has long wings, the water absorption capacity is poor, and the germination difficulty is a problem when planting toon, so it is necessary to prepare for seedlings before propagation, and the specific requirements for seedlings are as follows:

2. Soak seeds in warm waterAround March every year, it is the day of spring flowers, this time is also the best time for toon soaking, to soak the seeds in warm water at 35-40 degrees for about 24 hours, and then take out the seeds and put them in a wet cloth bag, germination under constant temperature conditions, the temperature is best guaranteed to be about 20-25 degrees, watering 2 times a day, each watering time to turn the wet cloth bag over once, the seeds can be used for sowing after the germination rate of more than 50%.

The most suitable growth environment for toon is: sufficient sunlight, sunny leeward, deep soil layer, fertile soil, convenient drainage and irrigation slopes, if it is a plot of seed sowing, the plot should be deeply cultivated in advance before sowing, and apply foot fertilizer. The seedling spacing is 10 375px, and 6 August is the rapid growth period of seedlings, which should be combined with loose soil weeding, top fertilization 1 2 times, and the seedling growth rate is slow after September, and then appropriate fertilization is applied to promote the lignification of seedlings.

The height of 1-year-old seedlings is generally more than 1m, and the ground diameter is 25px, and they can be planted in the nursery.

The biggest problem with toons is that they die easily, and there are a lot of caterpillars. And the toon grows very fast, you can't let it grow all the time in the greenhouse, you have to prune the branches, in fact, the toon you just pick the toon buds he won't grow. You can pick it several times a year in the greenhouse.

It has the effect of stopping bleeding, dispelling dampness and relieving pain. The bark contains azadirachtin and tannins. Toon wood has a fine texture, toughness, decay resistance, easy processing, elasticity, and is an excellent material for construction, ships and vehicles.

Sawdust and roots can be used as aromatic oils, which are used as flavoring agents for cigars abroad.

Seedlings begin in the spring of the following year. After the sting, you can start raising seedlings. Before raising seedlings, it is necessary to soak seeds with warm water to promote germination, and then sow 3 kg per mu, which can produce about 10,000-15,000 seedlings.

It is also possible to bury roots and leave roots to raise seedlings. 1-year-old toon seedlings are more than 1 meter high, good seeds are generally reddish-yellow in color, full of particles, the most suitable seeds are red toon seeds, the emergence rate of seeds of this variety is higher, and the quality is better. After the seeds are prepared, germination is required, and germination is relatively simple.

Toon seedlings first need to be soaked in seeds to promote germination, but also to prepare fertile and loose soil for toon seedlings, can be used to add rotting farmhouse fertilizer as a substrate in the garden soil, after the toon seedlings plant to the soil, keep the soil moist, apply urea water once a month, when the seedlings are 10 15cm, prevent being burned by the sun The leaves are even-pinnate compound leaves, 30-50 cm long, the leaf edge is jagged, and the back is often pinkish-green. Flowers, calyx 5-toothed lobed or shallowly wavy, covered with villous, panicles, white oblong. The fruit is an oval capsule.

The flowering period is from June to August, and the fruiting period is from October to December.

First of all, it is necessary to select high-quality seeds, heat preservation and germination, sow seeds in a timely manner, regularly arrange and fertilize, colonize density, fine management and so on.

Be sure to choose the right time for sowing, pay attention to the depth of the seeds when sowing, choose excellent seeds in advance, and also promote germination in advance, but also pay attention to the density of planting, and also fertilize in time.

To choose the right variety of seedlings for planting, you need to choose the right land for cuttings, you must manage it in accordance with scientific methods, pay attention to the cleaning of weeds, pay attention to the prevention and control of pests and diseases, and spray pesticides in time.

First of all, you must choose seeds with full grains, be sure to germinate before planting, soak them in warm water at 40 degrees for 5 minutes, remove the seeds and cover them with cloth, and germinate them in an environment of 20 to 25 degrees. Then before planting, be sure to choose sandy soil, and be sure to prepare the land and fertilize it.

The planting methods of toon include seed selection, seed soaking and germination, nursery land, sowing seedlings and planting; The planting time is in early spring in March

First, the planting method.

1. Seed selection Choose excellent toon varieties with red and yellow color, full particles, no diseases and insects, no mildew and high germination rate.

2. Soak seeds to promote germination.

1) Soak the seeds in warm water at 20-30 for about 12 hours, then remove the seeds and wash them with warm water.

2) Then put the seeds into a bag to germinate, keep the temperature at about 25, and sow after the seeds germinate.

3. Nursery ground.

The seedling plot should choose sandy soil with fertile and loose soil, deep tillage layer, convenient drainage and irrigation, leeward and sunny and sufficient sunlight.

4. Sowing seedlings.

1) Usually sowing seedlings are carried out in May and June, and planting furrows are opened, with row spacing of 25-30cm and furrow depth of 3-5cm.

2) Spread the seeds evenly into the planting furrow, then pour the bottom water and cover the soil compacted, and the thickness of the covering soil is.

3) Generally, 5-7 days of sowing can be germinated, need to be watered in time and cultivated loose soil, when the toon seedlings grow about 5 true leaves, you can transplant and plant.

5. Planting Select 1-year-old toon seedlings with full top buds and strong roots for transplanting and planting, the plant row spacing is 8-10cm, 500 plants can be planted per mu, about 40-50 days later, the first batch of Tsubaki buds can be marketed after harvesting.

2. Planting time.

Toon trees are suitable for planting in the spring, in early spring in March, and the timing is adjusted according to the specific local climate, and if spring is missed, it can also be planted in the autumn when the climate is stable.

Methods of management of toons

1. Buckle the shed in time.

If the toon is planted after November, because the temperature is low, it needs to be buckled to warm up.

2. Adjust the temperature and humidity.

1) 1 week after transplanting, you can keep the temperature in the greenhouse at 15 without increasing the temperature in the greenhouse, which is conducive to slowing down the seedlings.

2) Begin to warm up about 10 days after planting, the temperature during the day is 18-24, the temperature at night is 12-14, and the low temperature should be kept above 15.

3) After planting, water thoroughly, keep the air humidity in the shed at 80-85%, when the humidity is insufficient and too large, it is not conducive to the growth of the plant, when the humidity is not enough, it should be sprayed to replenish the water, when the humidity is too large, open the film for ventilation at noon on a sunny day to reduce the humidity in the shed.

3. Fertilization. 1) In spring, toon has strong germination ability, and more nitrogen fertilizer needs to be applied, 3000-4000kg of fermented pig manure can be applied, and 50-60kg of nitrogen, phosphorus and potassium compound fertilizer plus urea of about 15kg can be applied per mu.

2) After fertilization, it is necessary to water, apply 2000-3000kg of chicken manure per mu and water it before the fall of leaves in autumn to store nutrients for the tree, which is conducive to the safe wintering of the toon tree and the germination of the spring of the second year.

4. Cultivating and weeding.

In spring, weeding should be carried out, and the soil should be loosened after each watering, and the weeds in the shed should be removed at the same time, so that the root system of the plant can grow normally.

Toon cultivation technique in winter.

Winter toon is an out-of-season sprout vegetable, which is rich in nutrition, contains a variety of amino acids and trace elements required by the human body, and has a fragrant smell, which is deeply loved by people. The main cultivation techniques are introduced as follows:

First, the selection of varieties. You can choose high-yield, high-quality, and strong fragrance red toon varieties.

2. Cultivation facilities. It is easy to use and has a bamboo bow greenhouse with little investment. According to the height of the greenhouse, 3-5 layers are generally discharged. Perlite can be selected as the cultivation medium. The cultivation tray is made of black plastic tray, and the specifications are: 60 cm, 30 cm, 5 cm.

3. Cultivation time. Generally, it is sown about 25 days before the Spring Festival, and it is marketed during the Spring Festival, which can play a considerable economic role.

Fourth, production technology.

1. Soak seeds to promote germination: select fresh seeds, remove the seed wings, put them in warm water of 55, stir constantly, stop stirring when the water temperature reaches 25, soak them in the water temperature of 20 for 12 hours, remove them and put them in 22-24 temperature to germinate for 2-3 days, and wait for the small buds to be exposed to sow seeds.

2. Sowing: Use a layer of waste newspaper to pad the bottom of the plastic plate, put in perlite, about centimeters thick, water thoroughly, the amount of water is 2 times that of perlite, then sow the seeds evenly, and then cover a layer of perlite on it, which is centimeter thick, and then water thoroughly.

3. Management: The temperature in the greenhouse is kept at 20-25, the humidity is about 80, and the seedlings can be basically completed in about 1 week. Due to the low carbon dioxide content in the greenhouse, plants need a lot of carbon dioxide to grow.

According to experiments, the concentration of carbon dioxide required for the growth of vegetables is 1000-1500 milligrams of liters, which can grow by 15-20 . The easiest way to replenish carbon dioxide is to release dry ice, which can also be obtained by ammonium carbonate plus sulfuric acid.

4. Harvesting of large seedlings: After 15-17 days of growth, when the seedlings are 10-12 cm high, they are harvested and marketed.
