Propagation and seed retention are very important for agricultural production, how to propagate and

Spray lime water every half a month or so, when there are weeds to get rid of them in time, if the disease has occurred, you can spray ferrous sulfate solution for prevention, and then spray water to wash the seedlings, the effect is better. In the case of sporadic disease, the diseased plants can be uprooted and burned, and then the soil can be disinfected.

When planting toon, when using seeds for seedling, we should choose high-quality seeds for seedling, generally choose new seeds with a storage period of half a year, and use new seeds for seedling breeding can not only improve the germination rate of seeds, but also improve the quality of seedlings. Greenhouse planting toon can be divided into three kinds, one is to harvest a stubble of toon in winter, remove the greenhouse film and let it grow freely; the second is to plant toons and other greenhouse vegetables together to make reasonable use of greenhouse space; The third is to transplant the toon trees outside after the toon is harvested in the greenhouse.

<> in early spring, the young shoots and young leaves of toon germination, the aroma is overflowing, the quality of young leaves is beautiful, it is the traditional woody vegetable that the people of our country like to eat, cold dressing, frying, pickling and eating can be. The traditional cultivation of toon is mostly planted sporadically next to fields, roads, ditches and houses, and the varieties selected should be based on the growth habits of toons and the preferences of the local market. For example, choose a high-quality variety of purple toon, which has young shoots crimson, early germination, bright luster, long flavor, less fiber, more oil, and high quality.

In addition, there is also red toon.

Toon belongs to the family of neem of the order Sapindella, a large tree, produced in China, in addition to the toon buds for food, is also the preferred tree species for landscaping. It is rich in nutrients and has a therapeutic effect, mainly for the treatment of external cold, rheumatism and paralysis, stomach pain, dysentery, etc. Toon is not tolerant to frost, and the top buds dry up after frosting, and the cortex is destroyed, resulting in a large reduction in yield, so it is necessary to emerge from the nursery before severe frost from late October to early November.

After the seedlings are out of the nursery, they should be falsely planted, irrigated, and covered, and frost-proof and anti-draining. The root system is required to be intact, and the root length is more than 20 cm.

Choose flat terrain, sufficient sunlight, well-drained sandy soil and fertile soil as seedling land, combined with land preparation and fertilization, sprinkle evenly, and turn thoroughly. In about 1 m wide furrow according to 30 cm row spacing, ditch width 5 7 cm, ditch depth 5 cm toon and grain crops intercropping mode. Due to the relationship between the tall body of the toon tree and the picking of young shoots, its shading and shading are reduced, and it is suitable for planting on the ridge of the field, forming an intercropping mode with field crops.

First of all, the fertilizer should be applied at the time of planting, then again at the time of flowering and fruiting, and the watering and loosening of the soil should be carried out every few weeks.

The first thing is to choose high-quality seeds and moist and evacuated land, because such an environment is conducive to growth, and secondly, it is necessary to apply fertilizer regularly, top dressing and watering, and supplement sunlight.

The land should be made of black soil, which is more fertile and grows larger. Try to keep the temperature inside around 25. Proper lighting during the day. Cool down at night.

When planting toons in greenhouses, we generally dwarf the toon seedlings so that the seedlings can form more side branches and full top buds.

The time of dwarf of toon seedlings is in June and July, with annual seedlings, retain 20 25 cm for top short pruning, so as to promote the germination of side branches in the lower part of the main trunk, when the side branches grow to about 25 30 cm or more, the top is picked again, so as to promote the germination of secondary side branches of toon seedlings.

There is not much difference between greenhouse planting and ordinary planting, except for a regulation of temperature, some technology is required, as well as the concentration of chemical fertilizers, the amount of moisture, sunlight and so on.

It is necessary to prepare the fertilizer needed in advance, as well as the seeds needed, and the greenhouse must be built very solidly, and it is necessary to ensure that the greenhouse is built with sufficient water and sunlight.

1. Build a shed. The construction of plastic greenhouses should choose a place with leeward and sunny, flat ground, fertile soil and watering conditions.

2. Seedling. Greenhouse seedlings are not divided into seasons, as long as the temperature inside the greenhouse is not less than 12 can be perennial seedlings.

3. Management. The management of greenhouses is the key to high yield, the first year of seedlings to determine the density according to the actual situation, generally the higher the density, the higher the yield.

Fourth, bud picking. In general, it takes about 30-40 days from planting to the first bud picking without heating in winter.

Be sure to pay attention to the planting temperature of toon, be sure to write some high-quality seeds when choosing seeds, you must choose some flat soil, the light must be sufficient, and the toon should be fertilized as a whole.

At this stage, the planting prospects of toon are very good, many farmers began to plant toons by themselves, so there are many farmers in the near future who are asking how toon is artificially planted, what are the key points of toon artificial planting technology?

1. Propagation and seedling raising.

1.Planting and propagating.

Because the emergence rate of toon seeds is low, before planting, the toon seeds should be soaked in 30 35 warm water for 24 hours, and then taken out and placed in 25 places to promote germination. When the radicle is exposed to the size of the rice grains, the soil temperature at least 5 is at the time of planting. After the toon buds, the seedlings are developed when there are 2 3 true leaves, and the seedlings are fixed when there are 4 or 5 true leaves, and the spacing between the rows is 25cm 15cm.

2.Spread the strain.

One way is to dig the roots of the seedlings in early spring, plant them in the seedling soil, and then carry out transplanting when the seedlings grow to about 2m in the second year; Another method is to choose the broken root heading method, in late winter and early spring, dig a 60cm deep annular ditch around the perimeter of the mature tree, break a part of the taproot, and then fill the ditch.

Two. Planting. Dwarf dense hair transplantation is a relatively perfect cultivation method developed in recent years, and its seedling cultivation method is sweet and sweet with the general planting seedling method, only in the planting specifications and tree pruning level, generally 600 plants 667m2.

The tree type can be divided into: (1) multi-layer type: when the seedling height grows to 2m, remove the top slightly, promote the germination of side buds, and produce 3 layers of backbone branches, the first layer is 70cm from the ground, the second layer is 60cm from the first layer, and the third layer is 40cm from the second layer.

This type of multi-layered tree has a higher stem, sufficient lignification, and a relatively stable yield. (2) clumping type: when the seedling is 1m high, it is slightly removed from the top, leaving new branches, only picking leaves without top buds, and then wiping the head when the branches are 20 30cm long, the characteristics are that the trunk is shorter and the branches are more.

Three. Management technology.

1.Temperature adjustment.

The greenhouse temperature is around 25, and the shoots can grow 3 4cm in 24 hours; When the greenhouse temperature exceeds 35, it endangers the color and quality of Tsubaki buds. 10 15d after the film is the slow seedling stage, the temperature should be effectively raised, and the greenhouse temperature can be around 30 during the day. Through the accumulation of sunlight temperature for more than 1 month, after bud germination, the temperature is controlled at 25 30 during the day, and the temperature is controlled at 13 17 at night, and the temperature is 18 25 during the budding period.

2.Ambient humidity adjustment.

The green seedlings in the greenhouse, the rhizome has poor water absorption, the early environment should maintain a high air humidity, the soil should be watered thoroughly after planting, and then watered according to the situation, and the air humidity should be maintained above 85%. After the budding stage, the air humidity should be 70%.

It should be to choose some fertile soil, and then plant toon seedlings in it, the temperature is controlled at 25, and the humidity may be above 70%, so that it will be easier to survive.

It should be planted by means of sowing, and we must pay attention to lighting when planting, and we should also water regularly, and we should also use some farm fertilizer, and we should also carry out weeding regularly and do a good job of insect control.

Be sure to understand the characteristics of vegetables in advance, ensure sufficient temperature, preferably maintain it at about 18 degrees, and also water regularly and do a good job of drainage.

1. Select seedlings.

When planting toon trees, it is necessary to select the best seedlings, and the quality determines the survival rate and growth. If the quality of the selected seedlings is too poor, it is difficult to survive, and it is difficult to manage. It is necessary to choose seedlings with good root development, no obvious yellow leaves, and disease spots.

2. Organize the plot.

The plot where toon is planted should be one with sufficient sunlight, soft soil and easy drainage. Turn the top layer of the soil once and then apply an appropriate amount of base fertilizer to increase the fertility of the soil. After processing, the furrow should be straightened, and the furrow surface does not need to be too wide, about one meter or so.

3. Plant seedlings.

Once the plot is organized, it can be planted. When planting, do not remove the soil from the roots of the seedlings, just plant them directly with the soil, so that you can adapt to the new environment faster. When planting, dig a pit of the appropriate size, and then put in the seedlings directly, and fill the soil and compact.

Pay attention to control the density of planting, not too dense. Water the seedlings as soon as possible after planting, so that the seedlings and the soil are more closely integrated.

4. Later maintenance.

After the toon seedlings are planted, they should be watered and moisturized frequently to meet the demand for water, and the environment is suitable and will soon resume growth. In the germination stage, it consumes a lot of nutrients, and it must be topdressed in time to ensure that there are sufficient nutrients. Not only that, but it should also be pruned in time.

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. Sowing, the sowing date is different from the north and south, generally 3 April temperature of about 15 can be planted, the nursery is selected in the leeward to the sun, there are irrigation conditions of the plot, with sandy loam soil as well, the land is prepared as a bed.

The toon seeds are smaller, and the bed soil must be finely crushed. With the treatment of toons grow very quickly, it can grow to about one meter a year, and it can be transplanted, the biggest problem of toons is that they are easy to die, and there are many caterpillars. And the toon grows very fast, you can't let it grow all the time in the greenhouse, you have to prune, in fact, the toon you only.

<> toon is a deciduous tree of the Neem family, Toon genus. Aliases: toon bud, big red toon tree, toon sky, toon bell, toon seed, toon, toon, tiger eye, tiger eye, big eye tree, toon flower, toon head.

Native to China, it is widely distributed in the Yangtze River and Yellow River basins, and seedlings begin to be raised 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 seedling super.

But some people are not used to eating, because he has a special taste, there are many ways to make toon, you can eat scrambled eggs, you can eat cold dressing, you can also make cakes to eat, etc., in short, there are many ways to eat. The toon tree is very good to plant, that is, in our yard to plant a random one to promote germination, generally need to put the seeds of the toon tree in about 40 degrees of warm water soaked for about ten minutes, when soaking it is best to keep stirring, so that it is more convenient for the seeds to absorb water. Then put the seeds into the water at room temperature and soak for about 24 hours, then the seed fertilizer is used as a substrate, the toon seedlings are planted to the soil, keep the soil moist, apply urea water once a month, prevent the seedlings from being burned by the sun when they are 10 15cm, and carry out topping treatment when they are 40 50cm.

When planting the germinated seeds into the soil, it is necessary to loosen them properly.

Red toon variety. In terms of sowing, seedlings are usually raised by means of seed seedling, and when the seedlings grow to a height of 1m, the top buds are erased to promote the side branches, and they can be transplanted into the garden in the autumn of next year. During the live broadcast, you can choose two ways: net seeding and direct dwarf dense planting (plant row spacing of 50cm) and inter-set live dwarf dense planting (wide and narrow band, broadband 4-5m).

The first step is to choose the right variety, then you need to choose a flat area for planting, you also need to loosen the land, and then you need to pay attention to the light and watering.

First of all, in the process of planting, we must pay attention to the spacing, and we must ensure that the sun shines, and we must regularly kill insects and fertilizers, and we must water frequently.

First of all, we should find a moist place before the soil is loosened, and make the toon tree worth doing, so that the toon will be more suitable for the growth of the soil, and there will be a better production value.

Toon seedlings are a kind of woody vegetables with high nutritional value, mostly cultivated in open field, and more used are dwarf dense planting cultivation technology, this method can be directly sown, and seedlings can also be transplanted. Let's take a look at a few key conditions for toon seedling cultivation and planting techniques.

1. Soil conditions for the cultivation of toon seedlings.

Toon trees prefer deep, fertile calcareous soils. It grows most luxuriantly on green sandy soil and bihe soil.

2. Light conditions for toon seedling cultivation.

The toon tree is both light-loving and light-avoiding. Photophilic means that high yields can be obtained with sufficient light. Avoid light refers to the strong direct light exposure of the toon trunk, and the long-term exposure to direct sunlight is prone to the phenomenon of partial trunk and sunburn disasters.

3. What temperature conditions do toon seedlings need?

Generally, the following periods should be controlled for the adjustment of temperature deficiency:

After covering the film, the indoor temperature of the shed should be controlled at 15 to 25 degrees Celsius during the day, and it should be ventilated and cooled in time if it is higher than 25 degrees Celsius. The night temperature is controlled at 10-15 degrees Celsius, and when it is below 10 degrees Celsius, the straw should be covered.

After about 15 days, after the sprouts germinate, the temperature is controlled at 25 30 degrees Celsius during the day and 13 17 degrees Celsius at night, with a minimum of 7 degrees Celsius.

After another 20 to 25 days, the bud length can reach about 20 cm, and the temperature is 18 to 25 degrees Celsius when entering the budding period. Spring reeds are lacking.

4. The humidity conditions required for toons.

After the toon seedlings emerge, the root system is damaged and the ability to absorb water is poor, so it is necessary to maintain high soil moisture and air humidity after transplanting in the shed. After germination, the relative humidity of the air should be about 70%. If the humidity is too high, it should be ventilated and dehumidified in time.

5. Harvesting method of Tsubaki buds.

On the day before harvesting, if the light is strong, the grass should be covered with shade to soften, and on the day of harvest, the light should be weak. Therefore, bud picking should be carried out in the morning and evening.

Shed buds can be harvested once every 10 days. After harvest, top dressing and watering are appropriate to promote growth. The toon buds before and after the Spring Festival should be carefully sorted out and bundled after harvesting, generally every 50 100 grams for a bundle, packed into a plastic bag and sealed to prevent water loss and wilting, and improve the quality.
