This way, yam is grown, and high yields are constantly rooted. Farmers’ friends look over it.
With the improvement of people’s health awareness, yam, a nutritious and healthy vegetable, is becoming more and more popular. So, how can the yam production be high for farmers?
Today, we will talk about the precautions for planting yam from some aspects of the growth of yam.
First, choose the land.
The yam is long and vertical to the ground, so the permeability is good, and the soil is best transported by the soil.
Because the rhizome of yam is very long, it is best to have a higher ground, which is conducive to the growth of yam seedlings, and the swelling of the rhizome.
One thing to note when selecting the land is that the same piece of land cannot be planted for many years, which will greatly improve the disease and insects of the yam. It is best to change the immunity of the yam by two-year rotation.
Every autumn, after receiving the crops, we must dig the trenches before the frost falls. At the same time, we should pile up the mature soil and the raw soil in the ditch, and check the hard things in the soil.Come out and avoid hurting the yam.
When the snow is snowing in winter, some eggs and grass seeds in the soil will be frozen and killed, which will reduce the pests and diseases of the yam.
Backfill the soil in the spring, and use a few feet for each layer.
Second, choose the species.
Choosing a good variety is the key to increasing production. Therefore, it is necessary to choose a small variety of high-yield varieties, high-quality varieties, and the right varieties, together with scientific cultivation, then the yam harvest has been successful.
Third, apply the base fertilizer.
Because the yam belongs to the rhizome plant, the yam needs a lot of fertilizer in the growth, and the yam fertilization is also very particular. Under normal circumstances, the ratio of nitrogen fertilizer 4, phosphate fertilizer 1 and potassium fertilizer 5 is fertilized.
Pay special attention to the yam base fertilizer. It should be mixed with compound fertilizer and organic fertilizer 25 cm below the soil layer.
The yam must not use chlorine fertilizer, which will seriously affect the quality of the yam, and it is easy to be injured during transportation.
After fertilization, watering should be done with water ditch. This time the amount of water must be large.
Yam prefers a warm environment, so wait until the weather gets warmer and start sowing, which will increase the survival rate.
The growth period of yam is relatively long, and it is about half a year, so the best time is around April 15 and the planting is completed by the end of April.
Fifth, cover the mulch film.
Yam needs to be covered with mulch film, so cover the soil after sowing, cover the mulch, the mulch can not only moisturize, but also keep warm, promote the emergence of yam, after covering the mulch, it usually takes about a week to emerge.
Make sure the land is flat before covering the mulch.
Yam does not like water very much, and the rhizome is long down, so it can absorb water by itself, but when the yam is long, it needs a lot of water. At this time, it needs to be watered, but remember not to have water in the ground.
