Why don t the yacon I grow bear fruit?

1. Varieties: Some varieties have heavy fruit cracking, and some varieties cause a certain expansion pressure due to the rapid expansion of the fruit in the later stage of fruit development, resulting in fruit cracking. Ukraine.

The fruit cracking rate of series varieties is more than 40%, such as early large fruit, choice, etc. Varieties with good flesh elasticity have light cracked fruits, and hard flesh cracked fruits are heavy, such as red and bright.

Red honey cracked fruit light, Brooks.

The red light cracks the fruit heavily.

The fruit with a high fruit setting rate is light, the fruit with a low fruit setting rate is heavy, and the tree with a high seed setting rate provides an average of relatively little water and nutrients per fruit, the fruit expansion rate slows down, and the fruit cracking is light, which is also one of the reasons why the fruit with a high fruit setting rate ripens late, such as Rabins, Pioneer, Sato Nishiki has light fruit splitting, and Rennie and other fruit splitting is heavy.

2. Soil: loose soil, good drainage conditions of sandy loam soil crack fruit light, poor drainage conditions, clay heavy soil crack fruit. Clay soil permeability is poor, after rain or watering, water is not easy to lose, so that the soil water content increases, the soil water content is too large, the water absorbed by the root system is transported to the fruit in large quantities, and the fruit cells are cracked due to water absorption and expansion.

The well-drained sandy loam soil penetrates quickly after watering, and the soil is not easy to compact, the soil has good water retention capacity, and the root system absorbs water evenly, so it is not easy to crack the fruit, such as some sandy soil, mountains, and plots with high organic matter content The fruit is light.

3. Moisture: When the fruit is nearly ripe, it is irrigated by rain or flooding, resulting in a sharp change in soil moisture, and the water is transported to the fruit through the root system, so that the pulp cells expand rapidly, and the expansion pressure in the fruit increases, which expands and breaks the peel, causing fruit cracking. Sharp changes in the moisture content in the air also cause fruit cracking if the ripening period is cloudy.

or rain, causing air humidity in the greenhouse.

Increase (more than 80%), after a sunny day or sudden release of wind causes the humidity in the shed to decrease sharply, which will also cause a large number of cracked fruits.

4. Weather: When the fruit is ripe, the cracked fruit is light in sunny weather, and the cracked fruit is heavy on rainy days. 5. Other reasons: The low content of calcium and potassium in the fruit can also cause fruit cracking. It has been determined that sweet cherries with high calcium content have light cracked fruits.

Yacon. Like a warm environment, the best growth temperature is between 20-25 degrees, after the seedlings are unearthed, the water and fertilizer management is relatively loose, yacon as an Asteraceae plant vitality and growth rate are very fast, but also a particularly light-loving plant.

The most important thing to do during the growth period is to give enough light, not enough light, yacon is difficult to bear fruit, this is the most important aspect of growing yacon, yacon ripens in autumn, can overwinter in the open in the south, and in the north it is necessary to dig out the rhizome for storage, the taste is sweet and delicious.

The yacon has not yet borne fruit in December, because the yacon tree is still small and has not yet reached fruit, and it may still need some growth before it can bear fruit.

If memory serves, it ripens in winter, and then its fruit grows with buds in the soil, so you have to look at the size of the tree, the time, and so on.

<> planting period is different in various places, generally in spring when the ground temperature of 5 cm is stable at 14-15 can be planted, the cultivation of protected land can be planted in advance, the planting method can be directly planted in the field, can also be used to nutrient bowl or nutrient bag in the greenhouse seedlings and then planted into the field, in summer can also be the branches and underground germination of side branches for cuttings planting.

Yacon, another name for chrysanthemum, is a perennial herb in the Asteraceae family, native to the Andes Mountains in South America. The inhabitants of the Andes Mountains cultivated this plant as a root vegetable, and the tubers of the chrysanthemum are rich in water and fructo-oligosaccharides, which taste sweet and crunchy, and can also be eaten as a fruit. In Taiwanese markets, vendors sell the roots of chrysanthemum potatoes under the name "underground fruit" or "Tianshan Snow Lotus", which are actually two different plants.

1. Time: yacon can be planted by sowing seeds, if you want to save time, you can directly buy seedlings for planting. The time for planting can be selected in spring or autumn, and the survival rate of planting is also high.

2. Seed selection: choose the right seeds before planting, as long as the seeds are full and disease-free, the survival rate is high.

3. Soil quality: The soil quality of planting is required to be loose, breathable, rich in nutrients, and the soil should be applied with base fertilizer before planting, so that the soil quality can provide the demand for growth and promote the healthy growth of seedlings.

4. Planting: Plant the selected seeds into the soil, properly water them to promote growth, and wait until the seedlings grow stable and can be planted and transplanted, and then pay attention to maintenance and management.

Yacon is a perennial herbaceous plant of the Asteraceae family and the genus Chrysanthemum, also known as yacon, chrysanthemum, 10,000 roots, etc., native to the Andes Mountains of South America, and is now cultivated in many parts of China. It is a very tall plant, which can grow to more than two meters, and produces small yellow flowers, edible roots, rich in water, and a relatively sweet taste.

1. Seedling selection: yacon is an exotic variety, because it is introduced into the inland planting, it is welcomed by consumers, but there are many channels for the introduction of yacon, so when choosing seeds, we must choose the seedlings of seeds, which can be judged from the appearance, requiring that the seed buds are full, no defects, the leaves are green, there are no signs of wilting, and the seeds and seedlings can not bite pests.

2. Planting time: As for the sowing of yacon, it is best to sow early, not late. We generally use the method of transplanting seedlings in nutrient pots, which is carried out at the beginning of April, and if the seedlings are raised in small arch sheds, it can be advanced to the end of March.

Mix the ratio of 1 into the matrix for use. Or it can also be replaced by cinder, humus, and perlite. In terms of light, yacon is a long-day plant, and in summer, it can be properly shaded from the sun, and it can be grown under scattered light, and the rest of the time can be exposed to sunlight.

4. Apply plantar fertilizer: Before transplanting, it is best to make full use of well-rotted human and animal manure in the field, and add a certain amount of high-quality phosphate fertilizer, potassium fertilizer, etc. If possible, we can add some trace elements to improve the quality of the product.

Before fertilizing, the soil must also be turned deep to increase the permeability of the soil and kill harmful diseases and insects.

5. Watering and fertilizing: If you are watering, you should water the snow lotus thoroughly after putting it in the pot, and place it in a place that can be covered with a travel cover to wait for new roots to grow. When growing, it can be dried before watering.

Be careful not to water the leaves when watering. In winter, a little water is fine. In terms of fertilization, nitrogen fertilizer is suitable for spring and phosphorus fertilizer is suitable for summer to help the growth of flowers and leaves.

In autumn, more potassium fertilizer needs to be applied to make the flowers more delicate and full. When the flower buds appear, the flower should be used to promote better flower quality.

6. Drainage and flood prevention: The growth period and middle stage of snow lotus should be watered according to soil moisture. Especially in June-July, the weather is hotter and the temperature is high, so you should water more.

However, soil moisture should be kept above 80% and not over-flooded. Otherwise, the soil will be poorly permeable and the oxygen content will be low, which will cause the roots of the yacon fruit to rot. In areas with a lot of rain and areas with low terrain, it is essential to drain water in time to prevent yacon from cracking in the later stages of growth.

7. Pruning: Too many branches will affect the growth of yacon, so we can leave 2-3 main branches, and the rest of the Senzhen pants should be erased. When the plant grows to a height of 50 centimeters, branches appear and we must cut them off in time.

Snow lotus root is also called "snow lotus", "fresh fruit lotus", the most common variety of snow lotus root is none other than Yugoslav snow lotus rootWith its high production capacity, good taste and many other advantages, once it is put on sale, marketing and promotion, it is favored by many lotus farmers and customers. Yacon is also known as Yagon, chrysanthemum, and ginseng fruit. Yacon should be taken with tubers, it is designed to be very similar to sweet potatoes, the fruit is juicy, sweet and crisp, and has a lot of water-soluble chemical fiber, it is a low-fat food, especially suitable for diabetics and their ** to take.

Yacon fruit is a rich source of minerals and nutrients with more than 20 essential carbohydrates and nutrients. It can cleanse the liver and detoxify and improve the body's immune function. Yacon branches, leaves and fruits can be produced and processed.

Yacon is used for both medicine and food. Yacon is afraid of frost, cold and cold, and is most suitable for growth and development, and the working temperature is in the middle of 18-24, and the altitude is about 1000 meters above sea level, and it is necessary to grow and develop in areas with large temperature difference between day and night, night tide and smoke, and fog water is more beneficial to the development and storage of nutrients in yacon.

The regulations on the quality of water are very high, and it is best to use mountain spring water or natural mountain spring water that has been piled up, otherwise it will not be good for the quality of yacon; Loose soil layers, red gravel soils, red soils and sandy soils with good ventilation are required, and other soil layers are not of good quality even if they appear to be large underground stems. Select neutral or slightly acidic and alkaline sandy loam soil with convenient irrigation, rich soil layer, thick soil layer (about 50cm above), and organic matter content above 15%. When ploughing, fine, uniform and loose are prescribed to create a thick, loose soil type, so as to improve the permeability, water storage, soil consolidation and drought tolerance of the soil.

It is beneficial for adequate growth and development of rhizomes and tuber growth. Yacon is a kind of green plant that loves warm conditions, plant growth and development is very similar to the same family of green plants: artichoke, and the growth and development speed is very fast, the working temperature is relatively high, less than 15 degrees will stagnate growth and development, so the sowing time should wait for the soil temperature to really warm up before it can be carried out, and to obtain are to be before the frost period, the disadvantage of hungerAfter October, when the temperature decreases, part of the road surface will dry up, and it will be excavated.

There is nothing related to the two. When the temperature rises, yacon can be sown. Generally speaking, the earlier the planting time, the higher the yield. Snow Lotus Youxiao fruit Chan dust production planted from May to June may decline.

Tianshan Snow Lotus, also known as Snow Lotus, is a plant of the genus Asteraceae, which is endemic to China. And yacon is a plant of the Asteraceae family Chrysanthemum, native to South America, introduced to Japan in eight years, and later introduced into China through various channels, China's planting of yacon is not long, only a short beam of pure rolling for more than ten years, although the snow lotus and yacon both belong to the Asteraceae family, but the Asteraceae family is a very large family, and yacon and Tianshan oak snow lotus, whether it is in biology, or in the growth environment, or in appearance, there is no similarity, so the two basically have nothing to do with each other. Do not plant in pots.

Yes, there is no connection between yacon and snowdrop, yacon is a fruit that has no medicinal value, mainly for health care.

Yacon seedling technology:

1. Seed purchase.

When yacon is planted, a good bulb or seedling should be purchased, and the bulb buds are required to be full and intact, the color is red, the seedlings are green and strong, and there is no disease or damage.

2. Planting time.

Yacon is best planted after cutting the bulbs, leaving 3 or 4 buds after the bulbs are cut, and the live broadcast should be before April 15. Mulch mulching and sowing at the end of March is good, and if there are conditions to build a small arch shed, the time can also be advanced. Nutrient bowl seedlings should be carried out in early to mid-March, and transplanted to the field after entering the frost break period and watered in time.

The earlier it is planted, the higher the yield, and the yield of yacon planted in May and June decreases significantly.

3. Prepare the land and ridge.

Choose sandy loam land with convenient drainage and irrigation, and not low-lying sandy loam land. According to the meter row spacing, ditching, evenly applied per mu fully decomposed human and livestock manure 2000 kg and 20 kg of compound fertilizer once applied. Then ridge (also called moisture), and then cultivate the soil height during the cultivation in the future, the purpose is to increase the daily temperature difference of the soil and promote the expansion of the fruit.

4. Post-management.

Yacon enters the flowering period in September, each branch opens five yellow sunflowers, and enters the maturity period after the flower failure, and can be harvested one after another after all the branches are defeated.

5. Timely mining.

The ripening of yacon's underground fruit is marked by the withering of small bundles of yellow flowers at the tip of the stem around October, when they can be harvested. It should be excavated and stored indoors or in a cellar before freezing. It can be stored like a sweet potato, and the stalks can be used as high-quality feed.

Leaves, flowers and fruits have high nutritional value, and can be dried to make tea or **. About 1,000 plants are planted per mu, and the general yield of a single plant is about 3 kg, and the highest yield per plant can reach 10 kg.

Yacon planting conditions:

Yacon fruit has been successfully introduced and cultivated in Yunnan, Fujian, Hainan, Guizhou, Hunan, Hubei, Shandong, Henan, Hebei, especially suitable for growing on sandy soil between 1000 and 2300 meters above sea level, likes light, likes moist soil, and requires that there are watering conditions, and will not be flooded terraces, terraces, gentle slopes, the growth period is about 200 days, the growth temperature is 20 30, the growth is stagnation below 15, it is not resistant to cold, and the stem dies in case of frost.

Yacon is a common fruit that is sweet and nutritious, and is loved by people. In the process of yacon planting, seedling cultivation is a very important link.

According to the transplanting time, the seedlings are planted one and a half months in advance. Spring transplanting seedlings can be started at the end of February and early March, and the greenhouse or ordinary room can be used to increase the temperature.

Nutrient bowl seedlings, first prepare nutrient soil, fertile and bacteria-free soil and a small amount of rotting fertilizer. Master the humidity of about 50%, hold it into a ball, and then put it into a 6-8 cm nutrient bowl, plant a single bud (the seeds are disinfected with carbendazim first), sprinkle soil to cover the bud eye, and spray it with a sprayer to spray water.

Control the temperature about 25, low can not be less than 15%, high should not exceed 35, generally about 10 days to germinate and emerge. Usually strengthen the observation and management, wait for 10 days before transplanting the seedlings to be refined, and transplant the field after the frost break period, and the plastic film cover is better.

When transplanting, use a shovel to take seedlings, and then handle them gently, transplant the field in time, and cover the transplanted field with plastic film (cover the film first and then plant the seedlings), so as to facilitate heat preservation and moisture retention. After planting, water and cover the soil in time. Transplant seedlings in early spring, watering or watering small water, and avoid flooding with water.
