Do you think that lotus root is a special product of our country? In fact, it is not. The origin of lotus root is in India, but it was introduced to China very early. Nowadays, many provinces in China have cultivated lotus roots. The following small series takes everyone to learn how to plant lotus roots. I. Selected fields Planting lotus root should choose low-wet fields with convenient drainage and irrigation, and the soil should be the best with green mud or yellow mud. Second, land preparation, fertilizer In general, the base fertilizer should be based on organic fertilizer, and the fertilizer must be fully decomposed. In order to fertilize the soil, the method of greening and greening can be adopted. In the selected field, the donkey or the pea can be planted. In the second year of the second year, the farmer can apply 2000 kg of the farmer’s fertilizer and plow the green manure, and then put the water into the field. After 10 days, 50-80 kg of compound fertilizer (three-way compound fertilizer) was applied to the mu, and then the fields were reclaimed. In the good field, apply 20 kg of urea, 100 kg of superphosphate, and 10 kg of potash as seed fertilizer, and sprinkle it on the surface and then plant it again. Third, choose the species It is necessary to select the whole sorghum species with the characteristics of this cultivar and the scorpion scorpion. The sorghum should be harmless and the buds should be intact; the seedlings must be planted in two or more sections, otherwise the germination power would be weak. 400 kg. Fourth, cultivation and planting Generally, the temperature is stable above 12 °C, and the ground temperature can be planted above 8 °C. Density: The row spacing is 1.8 meters. When the plant spacing is 1.2 meters, the bud head should be buried in the mud and kept parallel with the soil surface. Fifth, adjust the water level Within 30 days of planting, keep 2-3cm of shallow water to increase the mud temperature; keep the knot during the knot period of 7-8cm, the water layer promotes crusting, and prevent deep water flooding. Sixth, weeding After planting, before the lotus leaves are sealed, we must pay attention to weeding and pull the grass into the mud. Seven, the rotation Lotus roots will fall down after two years of continuous cropping, otherwise the corruption will occur, and the yield and quality will decline. Sixth, harvest: After the stems and leaves are yellow, the cockroach is mature at this time, and the water is dried out ten days before harvesting, and it can be harvested one after another. If you want to keep your own seeds, you can't cut off the water until the second year. Or leave the water after the water is kept until the second year of cultivating. Eight, top dressing When è—• 3-4 pieces of rod leaves are grown, 10 kg of urea is used, and 20 kg of potassium chloride or potassium sulphate is used. It is strictly forbidden to use nitrate nitrogen fertilizer. During the growth period, attention should be paid to the application of nitrogen phosphate fertilizer. In the conditional area, silicic fertilizer should be added, and micro-fertilizers such as boron, zinc and molybdenum should be applied. Do not apply chemical nitrogen fertilizer to improve the disease resistance of the plant. Nine, pest control The cockroach bacteria is the main source of the disease of spoilage. To prevent the disease, it is necessary to select the healthy plant from the disease-free field to plant the cockroach and eliminate the bacterial source. Before planting, the cockroach is 50% carbendazim or methyl. After rubbing 800 times of thiophanate or 800% of chlorothalonil WP, the film was sealed with plastic film for 24 hours, and then dried for sowing. Leaf spot disease: Control with carbendazim, use 4 for acre, spray with 30 kg of water. Aphids: Acre with buckwheat 4 2 with water 30 kg spray leaf stems. It is strictly forbidden to use highly toxic and highly toxic pesticides for pest control. Remove the diseased plants and completely remove the diseased stalks and diseased bodies, and bury them deeply or concentrate them. 50-100 kilograms of lime per acre before planting, both sterilization and cleansing, and accelerate the decomposition of organic fertilizer. The above is the planting points of lotus roots. We welcome experienced farmers to supplement them. Weinong.com is designed to share learning and communication.
