The video of how to grow yam can be found in major video websites, or go to the yam planting base to record on site.

Yam is not only edible but also has a high medicinal value, for example, its root has the properties of warmth and sweetness and can also remove the cold. When I was a child, adults would often use yam stew, it is said to be able to make up for the gas, so it is still quite hot in the market. So what are the growing conditions of yam? Look down the page.

The growth conditions of yam

A suitable temperature: yam is relatively not a great demand for temperature, as long as the temperature at each stage will not vary too much on the line. For example, yam in the sowing stage temperature should be about 15 degrees, the growth stage temperature should be 15 degrees -25 degrees or so, the growth stage temperature can not be lower than 15 degrees, the highest temperature can not be higher than 40 degrees, below or above this temperature its growth will be limited. In the plum local generally used is segmented planting, that is, the yam cut into a small piece and then in the nursery planting, using this way nursery seedbed temperature to reach about 23 degrees, so as to enhance its germination rate.

Two, suitable light: yam is a warm plant, in a sunny environment it grows better, if the planting place is too shady instead of affecting its growth, the growth of yam is also relatively small taste will be a lot worse, such as the starch it contains will decline. Last year, Plum did an experiment, half of the yam segments planted in sunny places, the rest of the segments planted in the shaded places, to the digging of the two sides of the yield difference is very large, almost double the difference, the yin plot of yam is not only small, with a lot of small thorns, scraping are difficult to scrape.

Three, water needs: yam has the characteristics of drought intolerant flooding, so the yam can not be planted in the perennial moisture plots, such as planting the environment is too wet on the growth of yam is harmful, too much water yam is prone to root rot phenomenon. Therefore, in the choice of planting land to observe how the drainage facilities of the plot, but not too dry, especially in the yam fruit rapidly expanding time, this period should ensure that the soil is moist, so that the growth of yam quality is good.

Four, soil needs: yam's head is very long, so in the choice of soil to choose sandy soil or sandy soil, followed by the above also said that the water table should be low, PH value if you can be between 6.5-7.5 is the best. In addition, in the selection of soil plots to avoid continuous cultivation, while turning the land should be applied to a sufficient amount of base fertilizer, base fertilizer can be used livestock manure or fermented straw and so on. Yam in the pre-growth period can use more nitrogen fertilizer, nitrogen fertilizer can make the yam vine grow more luxuriant, in the later stage can apply some phosphorus fertilizer or potash, these fertilizers can enhance the quality of the yam.

a, turn the ground digging ditch: it also said that the yam belongs to the deep ditch crops, so in the turning of the ground to dig the ditch deeper, the depth of at least to reach more than 60cm. In the process of digging a ditch, to put the underground soil on the other side, to facilitate its weathering. When planting yam you should first fill the underground layer of soil into the trench, and then the upper soil use the upper layer of dug soil, which is conducive to the later growth of yam. In addition, when turning the ground should be added to the appropriate amount of farmyard manure or organic fertilizer, but the use of farmyard manure should be rotted first, undecayed organic fertilizer is harmful to its root system.

Two, the treatment of yam seed: yam planting before twenty days or so can be yam seed cut section processing, cut section should pay attention to the length of the general 20cm or so, cut section to cut the section of the side of the quicklime or straw ash in the wipe a little bit, this step has a disinfectant effect on the incision, but also to avoid future production of germs. Smear on the lime after the section of the seed in the sun, to sun to the head of the section cracks, in the process of sunshine in the action of the seed should be gently to avoid the seed injury.

Three, planting yam: yam cultivation ditch to be done on top of digging a long 10cm role of the ditch, then put the yam into the ditch, covered with a layer of fine soil and then in the watering of the ground water, planting should pay attention to the spacing, the distance should be at least in the more than 10cm, the rows spaced in more than 40cm, put the yam seed to be placed flat. After planting is completed, you can also cover a layer of straw, or other mulch, mulch can increase the soil temperature makes the seedlings faster.

Four, frame, soil: yam belongs to the vine plants, to be it out of the seedling to give it a frame and organize the trails. In organizing the vine should be organized according to its characteristics, if there are a lot of side branches on the main vine of the yam, then you can cut off the redundant or poorly grown side branches, so that photosynthesis is enhanced, but also to avoid competition for nutrients. Yam in the growth of deep cultivation before the soil, soil this process is very important, the head of the yam is very long, such as not to cultivate the soil, if the yam fruit will grow to the soil outside, which will affect its subsequent growth, cultivation of soil can be on the ridge below the soil, the soil cultivated to the root of the yam is also conducive to the drainage of the future.

Fifth, the appropriate amount of fertilizer: the main yam vine to grow to half of the fertilizer, the fertilizer can be used at this time with compound fertilizer, usually an acre of yam can be used 50 pounds of fertilizer. Secondly, you can also open a 25cm ditch at the root of the yam, and then apply such as organic fertilizer, fertilizer should be watered to facilitate the absorption of fertilizer. When the yam leaves slowly turn yellow or thin after the fertilizer is applied, then urea should be used to remedy. Secondly, you can also spray foliar fertilizer on the leaves, foliar fertilizer can enhance leaf photosynthesis, but also to prevent early leaf senescence.

Sixth, water management: the above also raises the yam intolerant of waterlogging, so if you encounter a continuous rainy season to drain the water in a timely manner. In addition to watering after fertilizer when a sustained drought should also be watered, to market observation of the soil to see dry and wet as a standard. In the yam watering should pay attention to the time period, can not give its watering in the middle of the day, should choose the evening.

a, fertilizer, cover film: to yam high yield should be applied to the base fertilizer, base fertilizer can be used chicken, ducks, cows and other manure, you can also use organic fertilizers, such as potassium sulfate fertilizer or diammonium phosphate, etc., but also can be applied to the appropriate amount of trace elements. Yam planting can also be covered with a layer of film on the surface, the film has a heat preservation effect, making the seedlings faster, but after the seedlings will be timely removal of the film.

Second, yam seed treatment: yam is more prone to root rot and blight staring, so before planting to planting land spraying drugs, drugs can be used Amishida, etc., the drugs sprayed and then put the yam seeds, this practice not only prevents disease, but also improves its seedling rate.

Three, pests and diseases prevention: yam in the middle of the rainy season, such as encountered, in the humidity of the environment it is easy to cause a variety of diseases, such as brown spot disease, leaf spot, etc., so to prevent, can be used in the middle of the yam Amicida and Copper Goshen for spraying, half a month to use a continuous use of two to three times. If the yam appears yam bean should be removed in time to avoid competition for nutrients.

Summary: yam planting should pay attention to the choice of soil, such as soil is too hard, then it will be limited later growth, but also pay attention to water and light, the soil should be dry and wet, the sun should be sufficient, in this environment to grow the yam its quality and yield is high.
