Have not tried how to plant lotus root in dry land? planting lotus root in dry land is a new and efficient planting technology, which makes lotus root get rid of its dependence on water, realize dry planting of water lotus root, and the suitable planting area is expanding continuously. Because the dry planting area of lotus root can be large or small, simple management, less investment, quick results, benefit year after year, the general yield of lotus root per mu can reach 5000 kg. Therefore, the farming network has sorted out the method of planting lotus root in dry land, and the following detailed steps are listed for netizens' reference. Step 1, select the land for planting lotus root in dry land: select the land which is close to the water source, the soil layer is deep and has good drainage conditions, first dig the soil with manual or bulldozer, the depth is about 60 cm, and then use lime, cement and sand to cast the bottom foundation of the pool. Flat and firm. The pool wall is built with bricks or hollow bricks, with a depth of about 80 cm, including 50 cm below the ground. 30 centimeters above the ground. Leave a water hole at one end near the water source and a drainage hole at the other end. The bottom of the tiger pond is about 50 cm. The whole pool is glazed with cement to ensure no water leakage and no fertilizer leakage. Step 2, the treatment of lotus root planting land: select clay loam soil which can store water and rich in humus, mash, sieve fine and fully mature organic fertilizer, and fill it into the pond. The depth of the soil layer is 30 cm, and 5000 kg of fertilizer is used per mu. Step 3, select the lotus root: choose the whole lotus root with seed lotus root as the seed, which is beneficial to the germination of the new plant, about 400 kilograms per mu. The lotus root began to be drained around May 1, and there are two methods: water seed and dry seed. Water species refers to the discharge of water after filling, the water level submerged the soil layer 3-5 cm, then the row spacing is 1.0-1.2 cm, and then the section is slightly warped up. In order to increase the yield, the lotus root species should be closely arranged before and after. Dry planting means that after filling the soil, first open the ditch without water, the ditch depth is 10-12 cm, drain the lotus root seed and then release water. Step 4, lotus root pond management: 1, water level regulation: in more than 10 days after the discharge of lotus root, maintain the shallow water level to increase the pool temperature and promote germination. After the emergence of floating leaves, keep the water level at about 25 centimeters. In the whole growing period of lotus root, the water level should be kept constant. Rain Water is more in summer, so pay attention to drainage. 2. Adjustment of lotus root plants: about a month after planting, floating leaves are removed to reduce nutrient consumption and make sunlight penetrate into the water to increase ground temperature; pedicels are generally twisted and cannot be broken when picking flowers, so as to prevent Rain Water from invading and causing rot. 3. Topdressing of lotus root: under the premise of applying sufficient base fertilizer, generally topdressing twice. When 6-7 leaves of lotus root entered vigorous growth, 1000-1500 kg per mu of rotten manure, 25 kg of nitrogen, phosphorus and potassium compound fertilizer, 1500-2000 kg of manure per mu and 15-20 kg of diammonium phosphate were applied. Fertilization is selected in sunny and windless weather, shallow water level, which is beneficial for fertilizer to infiltrate into the soil, wash lotus leaves after topdressing, and then set the water level. 4. Disease and pest control of lotus root: the disease is mainly rot, which mainly invades the underground stem, causing browning and rot, and leading to aboveground withering. Use 50% carbendazim wettable powder 500 times liquid, add 75% chlorothalonil wettable powder 500 grams of fine soil, 25 kilograms, 30 kilograms of stew for 3 hours, sprinkle into the shallow water layer. The main pests are aphids, Spodoptera litura and so on. 1500 times of dimethoate emulsion or 1000 times of 50% wettable aphid powder can be used to control aphids and 1000-1500 times of trichlorfon can be used to control Spodoptera litura. Step 5, the harvest of lotus root: generally, lotus root can be dug before and after the Beginning of Autumn. No water is added 15 days before digging, and the harvest period is "Qingming Festival" in the second year. According to the market situation, the benefit is better when harvested in batches.
