Potatoes are the potatoes we usually call, and they can also be called artichokes, yam eggs, etc. At present, there are cultivated potatoes in many areas of China. What are the skills for high-yield potatoes?
1. Soil preparation, rational close planting
Although potatoes have a strong survival rate, good cultivation and water and fertilizer conditions can make them more high quality, high yield and high efficiency. Therefore, before planting, the site preparation work should be done, and sufficient water and fertilizer should be needed to improve soil fertility. According to local conditions, good varieties can be selected for reasonable close planting. After planting, a new high-fat film should be sprayed on the surface to maintain heat, moisture and fertilizer, and promote the emergence of seedlings.
2. Rational fertilization
Potatoes are crops that require more fertilizer, and the ratio of nitrogen:phosphorus:potassium is 4:8:12. In arid areas, loose soil, ridges and ridges need to be carried out immediately to increase soil permeability and prevent greening of the potato chips when exposed. During loosening, budding and flowering, proper fertilization, irrigation and timely application of new high-fat membranes should be carried out according to growing conditions to maintain soil moisture and fertilizer and improve efficiency. Weeds and insects should be removed to avoid loss of water, fertilizer and nutrients in the field.
3. Pest control
The main pests of potatoes include aphids, whiteflies and underground pests such as tigers, golden worms, crickets and crickets. If it is treated by spraying a target chemical or physical flooding.
4. Field management
In the flowering and expansion period, it is also important to ensure that there is sufficient nutrient supply such as water and fertilizer, and that it is necessary to properly regulate and tilt the supply of nutrients required for tuber expansion and growth. Before flowering, tuber formation and expansion period, the fruit should be sprayed in time to effectively control the excessive growth of the upper surface branches and leaves, accelerate the ultra-rapid expansion of underground tubers and enhance the insect resistance.
The above is the key points of high-yield cultivation of potatoes. Of course, there are not only four aspects, but also many aspects. Farmers' friends need to pay more attention.
