Potatoes are tuber reproduction, can be used as medicine, and are flat and sweet, and can cure stomach pain, ribs, edema and other diseases. When planting potatoes, proper watering can promote potato growth and increase potato yield. So, when is the potato suitable for watering? What are the correct ways to water the potatoes? Let's take a look at the time and method of watering the potatoes. When should potatoes be watered? Potatoes from the arches of the seedlings to the flowering, generally do not water, carry out seedlings, especially when it is dry. Cultivation experts have done a number of comparative experiments in soils with good water retention. Potatoes are 20% to 25% more productive than water-treated seedlings. The initial flowering of the potatoes begins to water. During the period from the initial flowering to the stem and leaf growth, the growth of the tuber is the largest, and the plant needs a large amount of water. On the other hand, the inorganic elements such as nitrogen, phosphorus and potassium required for the growth of potatoes must be dissolved in water to be absorbed by the roots. If the soil is dehydrated, there are more nutrients and the plants cannot be used. Generally, soil water holding capacity should be maintained at 60% to 80%. At this time, due to sufficient water, it often causes the potato to grow in the middle and late, consume nutrients and lodging, resulting in reduced production. To this end, we must implement chemical control. When the plant height of the potato is 50 cm to 55 cm, 50 g of 15% wettable paclobutrazol powder is sprayed on the acre, and watering is applied 4 days after the application, and an obvious high control effect can be obtained. The watering of the potatoes is stopped about 10 days before the harvest, which improves the quality and is more resistant to storage. The correct way to water potatoes 1. Before emergence: Do not top dress and water, the key is to increase the light to prevent the wind, snow and rain from damaging the arch shed. 2, emergence period: cover the film, it is necessary to manually assist the film break; open field growers, after rain or watering should be timely stroked, breaking the hard shell, so that the seedlings unearthed smoothly, promote Miao Qi, Miao Quan, Miao Zhuang. Watering in the seedling stage depends on the sensation of the situation, and the sensation is good or not, so as to avoid lowering the ground temperature. 3, the hair growth period: After the potatoes are out of the seedlings, the main target is to promote the growth of the scorpion, and build a shelf. The main point of management is that there is no drought and no watering. When watering, do not pass over the ridges, and carry out cultivating and cultivating the soil. Finally, before the squad is sealed, the square shoulders are smashed to create a good potato-forming condition. When cultivating soil, be careful not to damage the functional leaves. If the fertilizer is lacking, it should be topdressed in time, or it can be applied at the point of mouth, or it can be applied with watering. Large, medium and small arch sheds should gradually increase ventilation and ventilation time. After “Guyuâ€, the protection facilities can be removed depending on the weather. 4, the potato period: after the potato buds are buds, that is, start to potato, to the flowering period, the potato quickly expands, at this time should increase the amount of watering, if it does not rain should be poured three water, 5-7 per water interval In the day, you should pour small water and avoid the flood of water. The principle of watering is to keep the soil moist and not to cause water in the field. In this period, attention should also be paid to the prevention and control of pests and diseases, especially potato diseases. It should be based on prevention in advance to prevent the main disease. 5, harvest period: potatoes should stop watering 7-10 days before harvest.
