Potato, also known as potato and potato, is a high-yield crop that combines both food and grain. It is also a heroic plant that has made extraordinary achievements in the fight against famine and disaster in the world. The planting area is very wide and the adaptability is very strong. It is an industrial pillar crop that is particularly loved by farmers in mountainous regions, hills and plains. From the time of planting and harvesting potatoes to the period of seedling emergence, tuber formation, tuber expansion and starch accumulation, the management of the field during this period is very important for stable production and high yield.
First, set up fertilization, rational close planting. Although the potato's adaptability to survival is strong, good conditions for water and fertilizer farming can make it more efficient, high-yield and more efficient. Therefore, it must be well-grounded, full of water and fertilizer, and strong land before planting. To select suitable varieties suitable for local conditions and plant them in close quarters, apply new high-fat membranes on the surface after the next planting, so as to keep warm, protect the soil and preserve fertilizer, and promote the emergence of seedlings.
Second, soil conservation promotes weeding and weed control. Since the tuber formation period, potato growth has entered a period of accelerating accumulation accelerating the expansion. Therefore, the relevant plant protection measures must keep pace with the fact that potato is a crop that requires more fertilizer, and the ratio of nitrogen:phosphorus:potassium is 4:8:12. In arid regions, ripping soil and cultivating soil in time will increase the permeability of the soil and prevent it from turning green. In the loose soil, flowering buds should be based on the growth of reasonable chase fertilizer, irrigation and timely spraying of new high-fat film to protect fertilizer and increase efficiency. To eliminate weeds and to prevent the loss of nutrients in the field. The main diseases in potato growing season include early blight, late blight, ring rot, black shank, mosaic virus disease, leaf rolling disease, bacterial wilt, black shank, etc. The pests include locusts, whiteflies and underground pests. , Golden worms, cockroaches, cockroaches, etc., if the use of more targeted chemical spray or physical drive and other comprehensive management.
Third, control the leaves to promote stems, accelerate the expansion. In the flowering and expanding period, in addition to guaranteeing sufficient supply of water and fertilizers and other nutrients, it is very important to regulate and tilt the nutrient requirements of tuber enlargement and growth in a timely manner. It is necessary to timely spray the fruit shuangtingling before flowering, tuber formation and expansion to effectively control. The upper branches of the ground are mad, accelerating the ultra-fast expansion of underground tubers, enhancing the ability to resist insects and ensuring the quality and efficiency of the potatoes and the harvest.
