Potato yield skills

Potatoes, also known as potatoes and artichokes, are economically profitable crops that are both food and grain. They are also the heroes of the world in the history of famine disasters. It has a wide planting area and strong adaptability. It is an industrial pillar crop that is especially loved by farmers in mountainous areas, hills and plains. From the planting to the harvesting, the seedling stage, the tuber formation stage, the tuber expansion period and the starch accumulation period have been well done. It is very important for the stable production and high yield of this field.

1. Soil preparation and rational planting. Although the survival adaptability of potatoes is strong, good water and fertilizer conditions can make them high quality, high yield and high efficiency. Therefore, before planting, it is necessary to make a good ground, full of water and fertilizer, and strong ground force. It is necessary to choose a suitable variety suitable for local conditions and plant it in a close planting manner. After the next planting, a new high-fat film should be sprayed on the surface to keep warm, protect and protect the fertilizer.

2. Soil conservation and fertilizer promotion, pest control and weeding. After the tuber formation period, the potato grows into a stage of accelerating accumulation and accelerating expansion. Therefore, the relevant plant protection measures must keep up. Potatoes are crops that require more fertilizer. The ratio of nitrogen:phosphorus:potassium is 4:8:12. In arid areas, it is necessary to loosen the soil and cultivate the soil in time to increase the permeability of the soil and prevent the potato from exposing to light and turning green. In the loosening of the soil and the buds, it is necessary to properly apply fertilizer, water and timely spray new high-fat film to protect fertilizer and increase efficiency. Weeding and weeding should be done to avoid the loss of water and nutrients in the field. The main diseases of potato growth period include early blight, late blight, ring rot, black shank, mosaic virus disease, leaf rolling disease, bacterial wilt, black shank, etc., insects have aphids, whiteflies and underground pests. , Golden Needles, cockroaches, cockroaches, etc., if the use of more targeted chemical spraying or physical blasting and other comprehensive management.

3. Control the leaves to promote the stem and accelerate the expansion. In the flowering and expansion period, in addition to ensuring adequate supply of nutrients such as water and fertilizer, it is very important to rationally regulate and tilt the nutrient demand for tuber growth. It is necessary to spray the fruit and fruit at the appropriate time before flowering, tuber formation and expansion. The upper leaves of the earth's surface are mad, accelerating the rapid expansion of underground tubers, enhancing the ability to resist pests, and ensuring the high quality, high efficiency and good harvest of potatoes.
