How can yam cultivation achieve a bumper harvest? As we all know, in addition to the value of yam, the medicinal value is also a major point. The yam can cure short-frequency urination, spleen diarrhea and so on. Let's take a look at the high-yield points of yam.
First, the selection of resistant varieties
Choose a variety with strong disease resistance, such as Taikoo Mao Yam, etc., of course, also consider this species is not suitable for your geographical environment. When cultivating disease-resistant varieties, the varieties can be changed every two to three years, and attention should be paid to the purification and rejuvenation of the varieties.
Second, the rotation
Rotation can reduce the harm of yam pests and diseases, and can be rotated with crops that are not infected by wheat, radish, watermelon, corn, etc., at least once every three years. If it is a plot of cultivated yam all year round, it should be done once a year. Of course, water and drought rotation can be implemented in areas where conditions permit, and this mode has better control effect.
Third, land preparation
First of all, the plot should choose a sandy loam with a high topography, a dry climate, and fertile soil, and then carry out land preparation. The residual disease on the surface of the earth can be turned into the way to accelerate its decomposition. The biggest role of land preparation is to eliminate the pathogens in the soil in winter.
Fourth, fertilization, irrigation
Yam is also a kind of hi-fertilizer. When it is grounded, it must be applied with decomposed organic fertilizer. Phosphorus and potassium fertilizer can enhance disease resistance. Nitrogen fertilizer should not be applied too much, and it is easy to cause yam anthrax.
The principle of watering the yam must be thoroughly poured. If it is not poured early, there should be no water left in the land. In the rainy season, it should be drained in time to avoid root rot.
Fifth, the surface cleaning
Weeding should be removed manually. If the yam is found, the stems and leaves of the yam should be removed in time. When harvesting yam, remember to burn the weeds and sick bodies left on the ground intensively or take them to other places for deep burial.
Well, the high-yield cultivation points of yam are introduced to you so much today. If you think it is not bad, you will continue to introduce more to the farmers next time, first pay attention to Hui Nongwang!
