1. What are the key points of yam cultivation?
1, loose soil
The degree of soil looseness is very important for the growth of yam rhizome. Using the degree of looseness can promote the effective elongation and expansion of yam rhizome. When planting, the depth of planting ditch should be dug to about 1 m, which is soft enough to effectively improve the ground temperature and promote the germination and emergence of stem seeds. If the soil is not soft enough, the soil is hardened and the permeability is poor, which will reduce the yield and quality of yam. Farmhouse manure or crushed crop straw can be mixed in the soil, which can not only improve the soil fertility but also enhance the soil.
2. Apply sufficient base fertilizer
Base fertilizer is the key to ensure the early growth of yam. In order to meet the needs of yam growth, the nutrient base fertilizer must be sufficient. The base fertilizer is mainly decomposed farm manure, which must be fully decomposed to prevent the heat generated by fermentation after being applied to the field from burning the roots and affecting the growth of yam. If possible, an appropriate amount of biological bacterial fertilizer can be applied, which can be fully mixed with the soil, and then placed in the planting ditch, and then watered. When the soil temperature rises to about 16 degrees, sowing can be carried out.
3, treating seedlings
Yam is often infected with some diseases and insect pests, such as root rot and damping-off, which will seriously harm the growth of yam, reduce the yield of yam and affect the economic benefits of planting. Therefore, the yam seeds should be disinfected before planting, and then soaked with chemicals such as Tolstoy and sprayed with sterilization in the planting ditch for sowing, so as to reduce the phenomenon of yam seedling death. In spring, the insect pests are more serious, so it is necessary to spray phoxim and other chemicals appropriately to prevent the yam plants from being injured.
4. Protect the stems and leaves
When yam grows to the middle stage, the weather changes greatly and it is mostly rainy, so the humidity will increase and it will easily lead to various diseases and pests. Therefore, it is necessary to spray Amisi and other chemicals regularly to prevent and protect the stems and leaves of yam from being injured and affecting the growth, which is only about three times a month. Corresponding prevention and control should be carried out according to the types of diseases, and the diseased plants should be treated in time to avoid unnecessary losses. In addition, attention should be paid to removing yam bean to prevent excessive nutrient consumption and increase the planting cost.
Second, what is the profit of yam planting?
To know the profit of Chinese yam planting, we must first know its planting cost. The planting cost of Chinese yam can be divided into two types: Chinese yam seedlings and buying yam bean. Generally speaking, it takes about 250 kg to plant Chinese yam on an acre of land, but it takes about 80 kg to plant Chinese yam in yam bean. The price of Chinese yam seedlings in the market is almost 4 yuan a catty, so it depends on which way it is planted. If you make a profit, you can produce 6,000 Jin of yam on average. If you subtract the cost according to the market compromise price of 6 yuan a catty, the average profit per mu is more than 20,000 yuan. In this way, the profit of planting yam is still ok.
Summary: The above is the introduction about the key points of yam planting and planting profit. It should be noted that the above yam planting profit is only for reference, and the specific profit should be based on the actual profit, hoping to help friends in need!
