Yam is a very popular food. How can yam be planted for high yield? Yam, also called yam, is a very popular food that many babies have just added as a supplementary food. Because it is easy to digest and absorb, it can protect the baby's delicate stomach and is suitable for people of any age. Yam is difficult to dig, and its roots are deep, so it will break if you are not careful. Although wild yam is delicious, it is difficult to dig through twists and turns. Although the artificially planted yam is not as delicious as the wild yam now, it is indeed much more convenient and faster than before. Then let's do it today.

1. Selection of Chinese yam varieties Chinese yam varieties are the first choice before planting Chinese yam. When selecting yam varieties, we should choose yam with high quality, good adaptability, high yield, good quality and less pests and diseases as seeds.

2. The soil for planting yam should be a field with loose soil and soft texture (because yam will change its growth and development direction when it encounters lumps in the growth process, causing it to bend like yam). The soil is fertile, convenient for irrigation through drainage pipes, and the soil layer is thick. There should be no sand in the range of at least1.5m. Before planting, the site should be excavated, and deep ditches should be dug in the range of1.5m. The total width between ditches should be kept at 80cm.

It is difficult to dig, and mechanical equipment can be used to dig if conditions permit. After the yam ditch is dug, the stones and other dirt in the dug soil will be removed, leaving clean and soft soil, and then the soil will be backfilled into the pit, leaving a ditch less than the road surface 10 cm.

3. The planting method of Chinese yam seedlings can be planted with Chinese yam heads or with stems and buds. Note that yam heads should not be used for more than 3 years. The second method is to select yam segments and divide the yam into 8 cm segments with a thin yam. These methods all need to be cut at the same time of planting to keep the integrity of yam. You can soak the seeds in sterilized medicine for 3 minutes after cutting, or after cutting.

4. Planting method In the case of planting yam, it should be planted according to local weather standards, as long as the surface temperature is above 9℃. Conditional areas can also choose to cover with agricultural plastic film, which will cost more, but it will be beneficial to future management. Irrigation can be carried out in the yam ditch to keep the soil moist.

The yam segments and ditches are placed in a cross shape, and the planting spacing of yam is always kept at 24-25cm, and then the soil within 5cm is tightly covered. Fertilize yam after planting, and the fertilization position is 20 cm away from both sides of planting yam. Generally, organic fertilizer, urea solution, ammonium sulfate and calcium carbonate tablets are mixed and applied to soil, and then covered with 5cm soil to make a ridge bed.

5. Shelf management Due to the uniqueness of yam, underground stems belong to vines. After long-term excavation, yam seedlings will fall down and cannot stand on their own feet. Therefore, after the yam germinates, it is necessary to build a support frame for the yam, so that the vines of the yam can climb up with a support frame.

6. Irrigated yam likes sunshine, the indoor air temperature is relatively low, and the ambient temperature is relatively high. Generally, it only needs to be watered 7 times in the whole development cycle of yam. After watering before planting, you can water until all the yams emerge. The purpose of watering at this time is to promote the rooting and germination of yam, and the second watering is a bit key.

After the first watering, water it before it dries. Irrigation should be carried out according to the precipitation in this area. Generally, water is poured once every 15 days. When there is heavy rainfall in rainy season, the sewer should be drained in time. Avoid yam disease, avoid flooding yam in water.

7. Fertilizing Chinese yam requires a large amount of chemical fertilizer, including 2500KG of Chinese yam, base fertilizer 100KG, 58KG of phosphorus and potassium fertilizer and 9KG of potassium fertilizer. In the case of adequate fertilization for the first planting of yam, it can be fertilized once in the flowering period of yam, and when the hairy roots of yam swell, it can be washed and fertilized with mixed urea solution and ammonium sulfate, and in the middle and late stage of yam growth and development.

8. During the germination of weeding yam, if there is a lot of precipitation in rainy season, it is easy to cause soil hardening. At this time, it is necessary to loosen the soil immediately to avoid the influence of yam emergence. Many weeds will also grow during the growth of yam, and weeding in time will also help loosen the soil and increase air permeability.
