The management of potato growth period needs attention. It is a perennial herb of Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also known as eggs, potatoes, yam, etc., tubers of Solanaceae. With wheat, rice, corn, sorghum and become the world's five major crops. But how to plant is also a method, Xiaobian has compiled some for everyone:
Add fertilizer and water. During the period from the flowering period of the potato to the senescence of the stems and leaves, this period is also the period when the potato needs the most fertilizer and water in the whole life. Spraying the fruit and strengthening the nutrient flow, promoting the development and expansion of the fruit, and improving the water absorption and absorption of the plant, Improve fruit yield and quality. And 25 kg of NPK compound fertilizer per acre, or about 5 kg of high-potassium type fertilization to ensure sufficient water and fertilizer supply.
Pay attention to the soil. When the potato chips turn green, the content of solanine is increased. Not only does it taste spicy, but also the commercial properties are reduced, and there are symptoms of poisoning such as nausea and dizziness. Therefore, it is necessary to cultivate the soil in time to prevent the above phenomenon. The potato is generally cultivated twice, and the thickness of the soil is 3-4 cm to prevent the potato from being exposed to the ground.
Control is prosperous. The flowering period of the potato is also the most vigorous stage of growth of the stems and leaves of the aboveground part. At this stage, attention should be paid to controlling the growth and promoting the expansion of the potato tubers. According to the growth of the potato, the flower king No. 3 can be sprayed, forcing the topping to vigorously return a large amount of nutrients, and the main nutrient of the main body can be turned to the young fruit development system to enhance the fruit's swelling vitality, avoid the phenomenon of leaf hypertrophy and improve the field permeability.
