What are the requirements for the planting environment of yam?

Introduction: I believe that everyone is familiar with yam, it is a kind of food that grows in the ground, or it is the root of a certain plant, yam is also a kind of Chinese medicinal material, and it also has many uses in Chinese medicine. Yam is also a kind of food that people like to eat very much in their lives, people often use yam to cook porridge, today I will take you to understand the cultivation of yam.

1. Yam. Yam also has a name is potato root, it grows in the ground, and is vertical, cylindrical shape, and relatively long, its color is very similar to the potato, therefore, the potato also has another name called yam egg. Yam is widely distributed in our country, and many people will pack some fields to plant yams, yams are rich in starch, in our country, many people will use yam to cook, can be steamed and eaten, yam has a lot of benefits to people, such as being able to ** people's qi deficiency and indigestion.

Second, the planting environment.

Yams mainly grow at an altitude of more than 150 meters and below 1,500 meters, and they used to prefer sunlight, so when people planted yams, they often set up some shelves to let the yam vines climb on them, so as to better absorb sunlight. At the same time, because his roots are vertically downward, the length can grow to about one meter, so when planting, we should pay attention to the loose soil, so as to ensure that the yam can carry out a good echo effect, in addition, the temperature is also very important for the growth of yam, therefore, when planting yam, it is best to choose in spring and autumn, the temperature is suitable. <>

3. Cultivation technology.

When planting yams, a ditch with a depth of about one meter and a width of about 30 centimeters is usually dug to ensure that the soil is loose, so that the yam can better respire underground. In addition, after planting yam, a certain amount of fertilizer is also needed, and yam is a large amount of fertilizer, therefore, after planting yam, the yam should be fertilized in large quantities, and the yam should be watered regularly, and the discharge of water should be paid attention to when the amount of water is large.

It is necessary to choose some soil that is rich in nutrients, absorbent and breathable. Yam temperature requirements are very high, generally around 20 28 degrees, the temperature is too low the impact on the yam is very large, to regular fertilization, regular watering, but also to do a good job of pest control.

Sufficient sunlight and high temperature are required. Because yam is a light-loving and temperature-loving crop, sufficient light and higher temperature can make yam grow better.

It needs a very suitable temperature, it can only live in 15 20 places, and the soil is also very soft, with very good sunlight, and the soil is relatively well fertilized.

Yam mainly grows in valleys and slopes between 150-1500 meters above sea level, it likes light, and long-term light can make its branches and leaves more luxuriant, but it is not conducive to the development of tubers, so it is necessary to control the light time when planted artificially. The plant should be grown at a temperature of 15-20 at the seedling stage, and at 25-28 for adults, if the temperature is below 20, the growth of the plant will be slowed down. Yam is generally planted in a deeper soil, because its tubers grow vertically and can grow up to about 1 meter at most, if the soil is too shallow, the growth will be limited, and only some flat and tubular species can be planted in shallow soil.

It is important to note that loose and fertile soil helps the roots to breathe and also provides nutrients for its growth.

The requirements are still relatively high, first of all, the soil must be particularly fertile, and the water must be particularly sufficient, and then we must pay attention to the density of planting and the depth of planting, the temperature of the environment must be grasped at about 20 degrees, and the drainage of water must be good.

The soil requirements for planting yam are fertile and loose sandy soil, and it is also necessary to choose a relatively deep soil. Some corrosive substances should be prepared in the soil. Such soil is more suitable for the growth of yams.

Yam for the soil requirements are relatively high, in the planting of yam soil must be fertile, and to be particularly loose, to choose the soil with good air permeability, and to ensure sufficient light.

When planting yams, you must choose loose and fertile, rich in humus, and sandy soil with good air permeability, and also choose a soil with a thick soil layer and is not easy to accumulate water.

If the soil is too shallow, it will affect the growth of yams, and the soil must be loose and fertile.

The moisture content of the soil is relatively high, so as to ensure that the yam grows very well, the soil should be very fertile, and the surrounding environmental temperature is relatively high, which can ensure that the yam can grow very well in the process of growth.

The soil must be very practical, it must be nutritious, and it must be watered and fertilized so that it can grow better and at the same time increase yields.

Yam is a very common food, but in the process of growing yams, it is necessary to pay attention to various issues in order to allow farmers to obtain high yields and good quality yams.

First of all,Yams are generally grown at a temperature of around 10 degrees CelsiusTherefore, the temperature is too low or too high is not suitable for planting yams, most areas in the spring planting yam is the best season, and we must choose excellent varieties in advance before planting, do not choose those lesion lumps, and before cultivating yams, the lumps must be exposed to the sun, and then choose the time to plant the yam, but also need to do a series of follow-up preparations. <>

In the process of planting, tooIt is necessary to choose the right soil for pHYams prefer slightly acidic and neutral pH, and in the choice of soil, it is best to choose softer rather than clayey soil. <>

At the same time, in the process of planting yams, we also need to carry outDaily weeding and drainage measures, especially in the rainy season, we must do a good job of drainage in the field to prevent the roots of the yam from standing water, resulting in no way to get a high yield of the yam, and in the process of planting the yam, we must fertilize reasonably. Reasonable watering is also a very important issue, because the roots of yam are relatively deep, so when watering, we must ensure that the soil is soft, so that the roots of yam can contact with water, better growth, and in the drought, we must do a good job of watering, otherwise yam and may die due to lack of water. <>

In general,The most important issues in the cultivation of yam are temperature and soilTherefore, we must choose the right soil before planting, and at the same time, we must also pick the season, cultivate reasonably, and do a good job in field management during the planting process, and the most basic insect removal and weeding must be carried out on time, so that we can harvest high-quality yams.

The first is to choose sandy loam soil, the second is to carry out seedling treatment before planting, the third is to do a good job in water and fertilizer management, the fourth is to cultivate and weed, and the fifth is to pay attention to the prevention and control of pests and diseases.

First of all, it is necessary to choose more fertile land, and not too wet, the soil is deeper, and the light intensity is higher, on the other hand, organic fertilizer is better with biological fertilizer.

It is necessary to pay attention to the selection of land preparation and the selection of fertile and loose soil. At the same time, attention should be paid to water and fertilizer management. And it is also necessary to carry out reasonable topdressing. It should also be watered regularly. Prune the branches and leaves in a timely manner. It is also necessary to prevent and control pests and diseases in a timely manner and spray pesticides reasonably.

What should I pay attention to when growing yams? The following four points need to be paid attention to when planting yams: First, the land selection is high, well-drained, deep, soft sandy loam or loam fields, and the upper and lower soil quality is required to be consistent.

The soil should be slightly acidic to neutral. 2. Trench and prepare the long-rooted varieties according to the row spacing of 1 meter, dig a deep ditch in the field in the north-south direction, the width of the ditch is 28 cm 30 cm, and the depth is 140 cm. When digging, the upper and lower layers of soil are stacked on both sides of the ditch, and the 20 cm of sand at the bottom of the ditch is dug over the building on the spot.

After a few days of drying, the bottom soil is flattened and compacted, and then the lower soil and the upper layer of soil are filled respectively, and every 20 cm is filled to clean up all the rubble and debris. In order to facilitate the ditching, it is generally excavated in interlaced rows first, and the remaining half of the ditch is excavated after half of the ditch is filled. 3. Before planting, select the root head of the disease-free block that meets the characteristics of the planted variety for seeding, and dip one end section in the disinfectant lime powder to sterilize and promote germination.

Fourth, observe more, pay attention to the occurrence of pests and diseases, and prevent them in time.

1.Select an environment. Regardless of the crop, the choice of environment is important.

Yams like to be dry rather than wet, so when planting yams, the environment chosen should be dry and the terrain should be high. Because yams are afraid of fishing, when planting yams, drainage must be convenient. The other is the choice of soil.

The soil should have a deep soil layer, it must be soft, and the soil quality should be consistent up and down. Slightly acidic or neutral soils are best for yam growth. Yams generally cannot be sown continuously, and when crop rotation occurs, it should be once every three years in the middle.

2.Planting. Treat the seeds about half a month before the yam planting, choose the varieties that meet the needs of planting, generally choose the upper end of the root is harder, which is suitable for making seeds, dip the other end in slaked lime powder, and then put it in the sun to dry for a few days, you can sterilize the seeds.

When drying seeds, you should act lightly, and do a good job of wind and rain protection during this period. First of all, dig a trench, dig a trench according to the plant spacing of about 1 meter, the width of about 28-30 cm, and the depth of about 140 cm.

What are the key points that need to be paid attention to in the process of yam planting?

Key points of management in the process of yam cultivation 1

Protect the stems and leaves in the period, pay attention to three things.

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. You can spray 1500 times of amicida plus 600 times of copper noble, once every 15 days, a total of 2-3 sprays. Brown.

Color rot can be used to irrigate the roots in the above methods, especially after heavy rain.

The focus of viral diseases is to prevent and control whiteflies and mites. Pay attention to the topdressing of chemical fertilizer, 2-3 times in the middle of growth, and about 25 kg of potassium sulfate compound fertilizer per mu each time. Pay attention to remove yam beans in time to reduce nutrient consumption.

Key points of management in the process of yam cultivation 2

Fertilizer should be used sufficiently, and the mulch film should be covered.

More than 3,000 kg of well-rotted chicken and duck manure or pig and sheep manure, more than 50 kg of potassium sulfate compound fertilizer, and about 50 kg of diammonium phosphate are applied per mu. Conditionally, 100 kg of biological fertilizer and soybean cake fertilizer, one kg of boron-zinc-iron micro-fertilizer, and one kg of boron-zinc-iron micro-fertilizer were fully mixed with the soil and filled in the planting ditch. After filling with enough water, the seeds can be sown only when the ground temperature rises to 15 degrees.

After sowing, it should be covered with plastic film to improve temperature and moisture. At the end of May, the film should be removed to facilitate the root rooting.

Key points of management in the process of yam cultivation 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 seeds, you can use fludioxonil (Shile time) 1000 times or amicida 1500 times to soak the yam seeds, and spray along the ditch before sowing to ensure that the yam seedlings do not die.

In spring, there are more underground pests, mainly mole crickets, needleworms, grubs, and tigers, and the more effective method is to spray 1500 times of phosphine along the ditch. Or use a high concentration of Ruisheng (thiamethoxam) spray ditch to control underground pests, the effect is better and the safety is higher.

Key points of management in the process of yam cultivation 4

The soil is loose and the tubers are easy to swell.

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; The heavy clay soil is cold and hard, and the air permeability is poor, which is not conducive to the elongation of the roots, but the fertility is good and has stamina.

No matter what kind of soil quality, more than 1,000 kg of cow and horse manure or crushed crop straw (wheat and rice husk) can be mixed with each acre, which not only increases soil organic matter, but also improves soil permeability.

Large stones, bricks, and gravel in the soil should be removed to avoid damage to the rhizomes. It is best to dig a trench in advance before freezing, which is conducive to weathering the soil and forming a good soil structure.

Irrigation should be done as early as possible to raise the ground temperature as soon as possible.

Yam is also a common life food, by using it to survive, cooked or cooked seasoning good, its effect is to lower blood sugar, the best food for diabetes in the population, these benefits, although the market share is also more to see the profits of some breeders, which is actually the profit obtained by breeding feather prey, but many novices, can not breed or are not familiar with yams, in the breeding process inevitably increases the risk cost.

<> preparation before planting yams. It is necessary to carry out ditch treatment according to the characteristics of yam, because yam is a rooting animal, and the root depth can generally reach about 1 meter, so it is generally dug in the breeding base. This trench must reach a depth of about 1 meter, a width of 25 centimeters, and a distance of about 1 meter between the hooks, so that loose soil with a high soil layer can be excavated, plastic in the sun is needed, and then the ground is filled back to its original position, the dust returns to its original state on the soil changes that affect the normal growth of broilers after diet, phosphate fertilizer sulfur ammonia peroxide (persulfate) carbon fertilizer may have matured.

For seeds, it is usually necessary to cut and select the seeds about a month before sowing, generally choose a little thin yam, from which small pieces of about 20 cm are cut, a detailed pen is required to mark the upper and lower ends of each property, soaked in lime in the sun, the general power of the runway is already available, but in this process, pay attention to rain, moisture and wind to get the seeds, there is a good chance of germination, and then the bag and transport to the planting site must also act gently so as not to hang up or be turned over, may affect its germination.

If you want to double the planting from now on, pour concrete after putting jifi water in better land use and other land uses, the seed spacing prepared by each plant is about 20 cm, crush this pit, plum wood is generally about 4000 yams, cover about 10cm above the ground, combine some plastic film to insulate the soil temperature, you can wait for its normal growth.
