Doing a good job in several major links in production management will greatly improve the efficiency of yam planting. In the management of yam cultivation, the focus should be on the application of basal fertilizer, soil loosening, treatment of yam seeds, timely top dressing, disease prevention and control, and take measures to promote the growth of rhizomes as much as possible.

First, the soil is loose and the tubers are easy to expand.

The loosening of the soil is essential for the elongation and expansion of the rhizome. The planting ditch should be dug deep to about 1 meter, the sandy loam soil is loose and breathable, the temperature is fast, the early seedling is good, and it is conducive to the elongation of tubers; Mixed with cow and horse manure or crushed crop straw (wheat and rice husks are also acceptable) and new high-fat film, this not only increases soil organic matter, but also improves soil permeability.

Second, the base fertilizer should be sufficient, and the plastic film should be covered.

The base fertilizer is applied to well-rotted chicken and duck manure or pig and sheep manure, potassium sulfate compound fertilizer, diammonium phosphate. Conditionally increase the application of biological fertilizer and soybean cake fertilizer, boron-zinc-iron micro-fertilizer, and fill in the planting ditch after fully mixing with the soil. After filling with enough water, the seeds can be sown only when the ground temperature rises to 15 degrees.

After sowing, a new high-fat film and mulching film should be sprayed to improve temperature and moisture. At the end of May, the film should be removed to facilitate the root rooting.

3. Seedlings must be treated to prevent diseases and insects.

Yam is susceptible to root rot and blight after sowing, the easiest way is to treat the yam seed, you can use a new high-fat film (can be mixed with the seed coating) to soak the yam seed, repel underground pests and diseases, isolate virus infection, strengthen the respiration intensity, improve the seed germination rate, and spray along the ditch before sowing to ensure that the yam seedling stage does not die.

Fourth, the medium-term protection of stems and leaves, three pay attention to good.

When the yam leaves begin to expand, spray the herb root spirit on the leaf surface. The foliar photosynthesis products (nutrients) are transported to the root system, the nutrient conversion rate and soil loosening ability are improved, the rhizomes are rapidly expanded, and the medicinal content is greatly improved. In the middle of growth, yam has many rainy days and high humidity, which is easy to cause anthracnose, brown spot, nail spore leaf spot, brown rot and virus disease.

Pay attention to the topdressing of chemical fertilizers and remove yam beans in time to reduce nutrient consumption. At the same time, it is necessary to strengthen the comprehensive control of pests and diseases, and spray new high-lipid film to enhance the control effect. At the end of autumn, it is necessary to do a good job of wintering and cold insulation to ensure safe wintering.

It should be possible to be inexpensive, the economy of scale in infrastructure is a millimeter, and the pull bomb will be basically completed this year and next year.

Ma yam should not be planted in greenhouses, because its storage period is very long, and the conditions allow it to be stored for one year.

The planting time of yam varies depending on the region, but the planting time is April in the north and March in the south. Generally, yam is planted in February and March in spring, which not only has a higher survival rate, but also increases the yield of yam, and it will bloom from June to August after planting and bear fruit from August to October.

1. Get seeds: When the yam is in bloom, you can extract the seeds of the yam from the flowers, if you really feel that it is very troublesome, you can buy the seeds of the yam in the market, or directly buy the yam plants without any pests and diseases.

2. Seed treatment: After having yam seeds, you need to soak the seeds in clean water for 1-2 hours to promote the seeds to better take root and germinate.

3. Soil demand: yam has strong adaptability, low requirements for soil, it is best to plant in sandy soil with loose soil, high fertility, good ventilation and drainage, we can choose ordinary pastoral planting, add an appropriate amount of humus or organic fertilizer in it, increase the fertility of the soil.

4. Sowing and germinating: Sprinkle the soaked yam seeds on the soil, cover a layer of soil, water some water appropriately, keep the soil moist, let it receive sufficient sunlight, to help the seeds take root and germinate, about a month or so, the yam seeds can take root and germinate.

5. Scaffolding management: yam is a vine plant, when it takes root and sprouts, it can grow new shoots in about a month, at this time, it needs to be artificially framed with a wooden stick, and the shoots of the yam are fixed on the wooden stick with a rope, so that it can slowly climb and grow, so as to produce fruits with high nutritional value and delicious taste.

1. After the seeds are planted, the seedlings will appear in about 30 days, and the temperature should be above 20. After the sprouts appear, it is necessary to erect a scaffold, because the area of the yam attached to the ground is relatively large, and the branches are long and fragile, and if they are not put up with a shelf, they may break.

2. After the erection is completed, it is also necessary to ventilate between the yam rows and the rows, so that it can better accept the sunlight, which has a certain effect on promoting the healthy growth of the yam.

Ma yam is generally planted in April in North China, in May in Northeast China, and in Sichuan in March-April. The timing of cultivation varies from region to region, and it is usually planted during relatively warm times.

Hello, the reason why the ** of hemp yam in 2022 is high is because of its scarcity and high quality. Ma Yam is a kind of precious Chinese medicine, its raw materials come from Mashan, is an extremely rare Chinese medicine, and the return and because of its extremely high quality, it is also much more expensive than ordinary Chinese medicine.

The quality of hemp yam depends on its raw materials, which in turn depend on where and when it is picked. Only when it is picked at a specific place in Mashan and at a specific time can the quality of Ma Yam be guaranteed. And due to the scarcity of hemp yam, the picking location and time are very limited, so the number of picks is relatively small, which is why hemp yam** will be much more expensive than ordinary Chinese medicine.

In addition, the processing process of hemp yam is also very complex, and it needs to go through multiple steps to process the raw materials into the final finished product, which also increases the ** of hemp yam.

In short, due to the scarcity and high quality of hemp yam, as well as the complexity of the processing process, the ** of hemp yam is much higher than that of ordinary Chinese medicine, which is why the ** of hemp yam will be so high in 2022.

The reason why the ** of Ma Yam is so high is mainly due to the rarity of Ma Yam and the medicinal effect of its unique liquid. Ma yam is a kind of precious traditional Chinese medicine, due to its unique medicinal effect, it is widely used in the breeding disease of Duoqinyou, and its ** is also rising with the increase in demand. In addition, the planting area of hemp yam is very small, and the growth cycle is long, and the planting is difficult, which is also one of the important reasons for the high cost of hemp yam.

2. Analysis of different regions.

Yubo Zhiye monitoring data shows that on September 28, 2022, Ma Yam** in Central China rose the most, with an increase of 8 yuan jin (2022-09-27** reported 3 yuan jin). Iron stick yam** in the northwest region fell the most, with a decline of 1 yuan jin (2022-09-27** reported 8 yuan jin).

The white yam in central China is the highest today, reporting yuan jin, which is the same as the previous day (2022-09-27). White yam in South China is the lowest today, reporting yuan jin, compared with the previous day (2022-09-27.

Ma yam is a kind of medicinal material, mainly used for stomach pain, gastritis, gastric ulcer and other diseases. The main ingredient is 16 kinds of reed root grass, which is processed after long-term harvesting, drying, grinding, screening and other processes, and its medicinal properties are strong and have good efficacy.

Due to the serious damage to the ecological environment of Ma Yam by Douhu, the harvest of its raw herbs has been greatly reduced, coupled with the cumbersome production process, so that the top of Ma Yam is high. In addition, the medicinal effect of hemp yam is excellent, and it has an obvious ** effect, which is also one of the reasons for its high **.

First, weeding in time to avoid weeds from consuming nutrients; Second, timely watering, hemp yam still needs timely irrigation; Third, the prevention and control of pests and diseases, if there is a problem, spray in time.

If you want to have a high yield of yam, you should choose a plot with high dryness, soft soil, fertile and sandy soil that is conducive to drainage, so that the rhizome can be better elongated. It is also necessary to apply enough basal fertilizer to ensure that there are sufficient nutrients. After planting, it should be covered with plastic film to keep warm, so that the roots can be rooted deeper and conducive to later growth.

In addition, it is also important to apply different fertilizers at regular intervals depending on the growth.

The fertilization of hemp yam requires a balanced balance, especially the base fertilizer, which is the basis of high yield, and requires sufficient application, so organic fertilizer, chemical fertilizer, trace elements and biological accelerators are indispensable.

It is necessary to choose varieties of high-quality and disease-resistant seeds, pay attention to sowing in turns, and timely fertilization and watering.

Attention should be paid to the selection of yam planting; Farmers often pay attention to immediate interests when selecting seeds, and are accustomed to choosing the best and most uniform tubers. Most of the tubers left for seed use are low-quality, misshapen, and diseased tubers. This way the income may be higher, but first.

After two or three years, the pests and diseases are aggravated, the deformed roots increase, the yield and quality of yam decrease, and the benefit is reduced. Therefore, yam tubers should be neat, neat, disease-free, and replaced every 4 5 years to reduce the occurrence of variety degradation due to planting years. Pay attention to fertilization when planting yams:

According to the survey, farmers put about 800 yuan in one mu of chemical fertilizer, and the investment is getting bigger and bigger, but the output has not increased.

Chicken manure as a base fertilizer is beneficial for the growth of yams, but the chicken manure applied by most farmers does not decompose completely, resulting in an increase in the number of underground pests. In the process of decomposition, it competes with yam for fertilizer and water, and sometimes burns the seedlings, causing the seedlings to weaken and aggravate the occurrence of pests and diseases, but it has an adverse effect on the growth of the yam. It wasn't until mid-June that the horse yam completely converted its own nutrients, and the fertilizer effect of the fertilizer was almost lost.

It was found that the use of chemical fertilizer as top dressing instead of basal fertilizer was 3 times in late June, late July and mid-August, respectively. Compared with the two topdressing and basal fertilizer in mid-July and mid-August, the yield of topdressing only is higher.

Therefore, in fertilization, organic fertilizer is applied as basal fertilizer at one time, and fertilizer topdressing is enough. 20 kg of diammonium, 25 to 30 kg of potassium sulfate and slow-release fertilizer can be used as base fertilizer. Pest control: spraying 50% phoxanthion EC 1 000 times, 80% dichlorvos 1000 times and kung fu 3000 times on the surface and ground of the plant and the ground, which can control pests such as mole crickets, ground tigers, ladybugs, and green blind bugs.

Disease controlFor brown spot, anthracnose and leaf blight, post-emergence spraying is the key to control. It is necessary to grasp the critical period before the onset of yam seedlings after they are put on the shelves. If the first dose is late, the disease control effect will be significantly reduced after the onset of the disease.

The interval between medications should be flexibly controlled. The interval between continuous droughts can be about 1 5 days, and in case of rain, it can be shortened to 5 7 days. Before the onset of the disease and in the early stage of yam growth, 70% Antaisheng wettable powder was sprayed 700-800 times, 50% Fumei double wettable powder 500-600 times, and 80% mancozeb wettable powder 500 times, respectively.

After the onset of the disease, it is advisable to alternately spray 1000 times of thiamethoxam aqueous solution, 1 500 times of 25% amixisis suspension, and 800 times of 25% amidine wettable powder. Because the leaf surface of hemp yam is smooth, it is best to add binder when applying medicine.
