What are the common yams in China? Which is more suitable for northern planting?

In the Chinese herbal medicines, the origin of the medicinal properties, "orange Huainan for orange, Huaibei for the accumulation", the same is true for yam, born in Huaiqing Mansion is Huai Yam, born in other places is vegetable yam. The best way to plant yam is scientific crop rotation, so that the yield and quality of the planting are better, if continuous farming, it is prone to pests and diseases, and the quality will affect the sales, and the planting income will be damaged. Generally, there are cut faces when selling yams, look at the texture of the cut plane, the sticky juice is heavy, the texture is slightly thicker is the hairy yam, the color of the cut is slightly light yellow, and the cut surface of the iron stick yam (Huaishan, Huaishan yam) is obviously white, and the cut surface is clean.

When someone cooks a yam, it is found that the yam will turn gray-black and make a black soup. Experts tell us that this is because the enzymes in the yam change color when they come into contact with oxygen. Therefore, the yam turns black not because it has deteriorated, but it just indicates that the yam purchased is fresh.

The DHEA in the iron stick yam is called the youth factor, which is a very important activity substance in human life activities. It can effectively prevent the precipitation of blood lipids in the blood vessel wall and prevent heart and blood diseases. Therefore, eating more yam has the effect of prolonging life.

The most common ones on the market are iron stick yam, hemp yam, fine hair yam, water yam and Ganoderma lucidum yam. Especially in the northern market, there are many iron stick yams. Suitable for cultivation in the north, iron stick yam is the best.

Yams include iron stick yam, water yam, small white-mouthed yam, ox leg yam, hemp yam, Ganoderma lucidum yam, Yamato taro, and fine hair yam. In the north, Yamato long taro, nine catties of yellow, and iron stick yam can be planted.

In terms of planting time, all over the country should be selected according to the local climatic conditions and temperature suitable for yam germination of the best time to sow seeds, generally speaking, sowing concentrated in the spring of 3 April, the underground temperature reaches about 10 degrees, hemp yam is divided into several varieties, stick medicine and purple medicine is our common planting, stick medicine is shorter, thicker, purple medicine thin and long, everyone eats sugar gourd with hemp yam, is the variety of purple medicine.

Yams are planted in March, and at the junction of Daimyo and Henan are the concentration points for planting yams, and organic fertilizer is prepared in February every year, and it is officially planted in March. Yam is very common in life, it is not only nutritious, the taste is also very unique, many people like to eat, planted in the spring of 2 and 3 months every year, when the yam is flowering, you can get the seeds of the yam, you can also buy the seeds of the yam directly, generally after planting, it will bloom in 6 August, and it will bear fruit in 8 October.

There are many varieties of yam, but the main varieties are fine hair long yam, Ermao yam and Japanese yam, fine hair long yam and Ermao yam are long-pillar varieties Yam is also our more common variety, and Japanese yam as the name suggests is not a variety in our country, it is a variety after long-term cultivation, it has strong adaptability to the environment, and the quality is good, and the yield is higher than the ordinary variety.

If it is planted in normal North China, it belongs to the temperate climate, and it will enter the spring around February, which can be planted during this time, if it is in the Northeast region, because the climate is slow to regain spring, the surface temperature has not reached the planting requirements, and it can be planted in April. When the yam is planted in the spring, it is advisable to choose deep and fertile soil when planting, plant the seedlings after treatment, weed in time after planting, and set up a frame to lead the vines, and pay attention to the prevention and control of pests and diseases! There is a thin layer of clay in the lower layer, which can be dug up when digging a trench and can also be planted.

The soil should be slightly acidic to neutral. Yams cannot be cropped continuously, and should generally be rotated once every 3 years.

They are usually planted in March and harvested in October. The flowering period is from June to August. The fruiting season is from August to October. It can be seen that the growth cycle of yam is still very long.

Yams are generally planted in the second half of March every year, and the time for yam to bear fruit is about 10 months, so we generally choose to plant long-pillar yams, which we can often buy in supermarkets because it can be easier to grow and produce more.

It is generally planted in the spring and can be harvested in the fall, and the survival rate of yam is very high, so it is suitable for farmers to grow.

Because yam prefers warm and sunny places, it is not suitable for cultivation in Northeast China. Yams require fertile, well-drained sandy soil, prefer warm and sunny places, and avoid continuous cropping. The weather in the Northeast is relatively cold, which is not suitable for planting.

The Northeast region is not suitable for yam cultivation, mainly because the autumn and winter seasons in the Northeast are too cold, and yam prefers a warm climate.

Yam is a plant that likes temperature and sun, and the weather in the Northeast is too cold, there are often frosts, and the temperature is low, so it is not suitable for growing yams.

Yes, it's a good fit. Because the yam should choose a place with relatively high terrain and convenient drainage and watering.

Eat yam to see what advantages are absorbed, if it has a good taste, it must be produced in Wuzhi County and Wen County, the iron stick yam has a good taste, and it is produced in the main production area of authentic Huaiyao. If it is used for ** diseases and physical health care, Naken is still produced in Wuzhi and Wenxian and other main production areas of Huaiyao. The nutrient content is also insufficient.

The reason is that Shanxi is located in the area where the Yellow River flows, the soil is suitable for the growth of iron stick yam, and the yam itself likes drought and is afraid of waterlogging, and the climatic conditions of Shanxi are in line with its growth requirements, with long sunshine hours and little rain, so Shanxi iron stick yam is famous all over the country.

Iron stick yam is a yam species produced in the ancient Huaiqing area, called Huai Yam. The medicinal value is extremely high, and its original variety is the wild yam in the Shennong Mountains in the Tai area. Locals introduced it and planted it.

Gu said that if this variety is introduced to other places for planting, the quality will be poor. The best yam is the iron stick yam in Wenxian County, Henan. That's the best.

It has the highest nutritional value. Introduction of Wenxian Iron Stick Yam The hometown of Taiji, Sima's hometown, --- Wenxian County, is the main production area of the "Four Great Medicines".

The land of the county is divided into sandy soil near the Yellow River and sandy clay near the Qin River, and its dividing line is roughly in the line of Jinchangdian-Daquhe-Xiaonanzhang-Xulu Village, which belongs to the clay of the Qinhe River to the north and the sandy soil of the Yellow River to the south. According to the experience of local yam growers, Qinhe clay soil is more suitable for growing yams. The origin of iron stick yam is Jiaozuowen County, Henan Province.

The yam that I love to give birth to is also a medicine, and it is all a medicine in the middle! However, in recent years, there are many farmers who grow yam in Wen County, and there are cooperatives, with more output, large quantity, and great reputation. And close to the Qinhe River is the treasure of Wen County, the black hard and coarse non-sticky soil is just suitable for the growth of iron stick yam, because the soil is harder, so the yam needs to work very hard to penetrate into the ground and go up, the main production areas of yam are in Hubei, Hunan, Zhejiang, Jiangxi, Shaanxi, Gansu, Japan and North Korea and other places in China.

I think the yam production area should be in the south, because the climate in the southern region, Guangdong, Guangxi, and Yunnan is more suitable for growing yams, so I think it is in the south.

The general production area is in Hebei, Henan and Guangxi, and the production area of yam is completely different in taste and nutritional value, and the more famous is Henan's iron stick yam.

Yams are mainly produced in Jiangsu, Hunan, Guangdong, Guizhou, Sichuan, Shaanxi, Jiangsu and other regions of China.

Yam has a long history, low price and good quality. It is a tonic with the same origin as medicine and food. Yam contains nutrients such as saponine, mucus, allantoin, choline, arginine, amylase, protein, vitamin C, and vitamin B.

Yam is a tonic. It doesn't dry and looks mild. It can be used to alleviate the weakness of the spleen and stomach, whether it is the absence of spleen yang or the lack of stomach yin; into the lungs, spleen, and kidney meridians; It has the effect of spleen and stomach muscle strength, produces fluid with lungs, tonifies the kidney and improves sperm.

It is mainly used for spleen deficiency, lack of food, lung deficiency, asthma and cough, kidney deficiency, primary bleeding, frequent drinking, etc., using the method of clearing heat and quenching thirst.

Yam contains a digestive enzyme, which can promote the decomposition and enhancement of protein, is a natural health product for digestive diseases, and can also promote human metabolism, fresh yam tubers are rich in a kind of mucus, which can prevent fat deposition in the cardiovascular system, maintain the elasticity of blood vessels, prevent arteriosclerosis, and prevent the accumulation of excess fat. It can reduce subcutaneous fat storage and achieve the best effect.

The soil suitable for growing yam is sandy clay. After selecting the appropriate area, the selection and merit of the seeds is carried out. When you're done, place the flat groove on the sharp edge.

In a flat trench, some fine sand, sloth leaves and other soil must be placed. There are more than a dozen varieties of sweet potatoes, including common sweet potato, Lila yam, Huaishan yam, and yam that can be grown in most parts of China. Yam seeds can be sown and roots can grow.

Due to the vast territory of our country, the climate and soil quality of the east and west, north and south are different, and the cultivation time is also different.

It is mainly produced in the northern part of Henan Province, China. It also grows in Shandong, Hebei, Shanxi, central and southwestern regions. After the stems and leaves germinate in winter, dig and cut the roots, and there are two types of sweet potatoes in China

Regular sweet potatoes and sweet potatoes. Qianhuai Wangfu (now Jiaozuo, Henan, including Mengzhou, Boai, Qinyang, Wuzhi, Wenxian and other counties). They are rare, commonly known as "Huai Shu", commonly known as "Huai Shen", and are the most produced in China.

The main eggplant should be distributed in Henan, Shandong, Shanxi, Hebei and other provinces in China, and the requirements for scattered soil are relatively high, and they will generally be planted in fertile soil, and some flat terrain will be selected.

It is distributed in some places where the land is more fertile, and the terrain is the same as the special pit and flat, mainly in North China, and then also includes the northwest region, which is more famous than Nian Nian is the iron stick yam in Henan, and then in Sichuan, Yunnan and other places.

Site selection and ditching, the planting of yam should be as small as possible continuous cropping, generally every three years rotation, and avoid planting peanuts and red taro stubble. To choose a thick soil layer loose and rich plot of land as well, the left and right soil layers are consistent, the next layer has a clay layer and a white sand gang soil layer, when the ditch should be completely crushed, at least 1 meter of soil can not have clay, soil pebbles and other compartments. Otherwise, it will harm the appearance of the rhizome and the quality.

The soil is suitable for neutral, and at this stage, mechanical equipment is generally used for ditching. In addition to the northeast and northwest regions, other provinces, regions and regions are cultivated with yams.

Yams do not have a very high temperature requirement, but they prefer warmer temperatures. China's coastal areas are relatively warm, but in the northern part of China, there are also many areas where yams are cultivated, such as Shanxi and Shaanxi.

Special attention is paid to the yam or more cold, so to prevent frost fall, once the frost injury, even if it looks good yam, but also lose its own use value, before the analysis of the big frost, it should be dug from the field to store as soon as possible to reduce losses.

Yam is a drought-tolerant crop, but it is watered as much as possible to increase yields better. Generally, around the time of the first fertilization, in case of long-term drought, the soil is full of milky white, and it should be lightly watered 1-2 times to make the soil surface moist. From summer to autumn, if the drought is extremely hot for more than a week, it is also necessary to water cold water in the morning to withstand drought.

Yams are also afraid of waterlogging, so it is important to drain the pipes immediately during the rainy season to prevent water from storing water in the fields.

Extended Materials. 1. Yam because its roots are longer, so the regulations for land resources will be higher, its growth cycle will also grow, only once a year, generally its site can be selected in the terrain is higher and the soil layer is thicker, and the left and right soil layers are consistent, and the soil is more suitable for acidity and alkalinity to neutral.

2. Yam must be fertilized once after adding a base fertilizer in the whole process of growth and development, and it can be fertilized once after it has grown to about 20 centimeters on the ground.

It is suitable for planting in places with relatively high temperatures, humid soil, and fertile soil, especially in the northeast or northwest.

It is suitable for planting in Jiangsu, Hangzhou, Nanchang, Shanghai, Chengdu, Shaanxi, Xi'an, and these places can be planted.

Yams require fertile, well-drained sandy soil, prefer warm and sunny places, but are afraid of frost and avoid continuous cropping. China has been cultivated since ancient times, cultivated in the north and south, and has wild distribution, mainly produced in Henan, Shanxi, Shandong, Shaanxi and other places. Choose loose and fertile, well-drained sandy loam and no waterlogged clay, and loose and compact quality is good, but the yield is low, leeward and sunny cultivation is appropriate, and then winter turn about 66 cm, apply enough base fertilizer 5000 kg, deep turn 50 60 cm, spring shallow tillage 15 20 cm.

Before sowing, water the bottom water thoroughly, prepare the land for furrowing, most of them use ridge cropping, ridge width 120 cm, and the ditch between the two ridges is used for drainage and irrigation.

It is suitable for planting in plain areas, and in temperate continental climate areas, there is enough sunlight and not so much water, which is very suitable for the cultivation of yams, such as Shanxi, Hebei, Ningxia, Henan, these places will grow yams all year round.
