Cassava cultivation: what should be paid attention to in cassava cultivation?

What should I pay attention to when growing cassava? Please give an introduction to the cultivation of cassava need to pay attention to the following points: First, deep ploughing to improve the soil: in the month before planting cassava, first turn the land to white, so that the soil is fully weathered. 250-300 kg of phosphorus fertilizer composted with livestock manure is applied per mu as base fertilizer during planting. Second, the selection of improved varieties: must choose more tubers, less toxicity, high yield varieties. And select thick stem node density, no disease, no damage in the lower part of the stem as seed stem. 3. seedling treatment: 33 cm long seedlings are intercepted before planting, and the lower end is cut with an inclined mouth of 3-6 cm, which is duckbill shaped. Cut the seed stem bark every 2 nodes on both sides of the seed stem above the oblique opening, and break the cambium 2-3 places. The width of the cut is 1/4 of the circumference of the seed stem, and the length is 2 cm. This can make the root tuber grow more in the oblique opening and the cambium. When planting, adopt the method of controlling the growth of axillary buds at fixed nodes, except for the axillary buds at the top of the seed stem, remove the axillary buds at other nodes, and change the oblique insertion to horizontal insertion, which can control the growth of an ideal strong main stem plant. 4. Directional fertilization by stages: after planting, when the seedlings grow to 12-15 cm, the first fertilization can be carried out, and 30 loads of dilute manure water can be used per mu. In addition to proper application in the seedlings roots, focus on the application of seedlings 40 cm away from the surrounding, promote more roots, rapid extension. When the potato seedlings grow to 50 cm, apply fertilizer for the second time, drench with 40-50 parts of high-quality manure water mixed with 8-10 kg of urea per mu, apply fertilizer around 50-60 cm away from the plants, and make the potato roots extend along the topsoil tillage layer. When the potato seedlings grow to 70-100 cm, choose to top at noon on a sunny day and pick 3-5 cm of growth points. Then mu with manure water 60 load plus urea 10-12 kg drenching, promote its long branches. Fifth, autumn loose soil heavy fertilization: after autumn, choose sunny days, with a hoe to open the soil on the base side (pay attention not to damage the root tuber) exposed to the root tuber, let the soil exposure for 4-5 hours, then mu with ammonium bicarbonate 30 kg plus phosphorus fertilizer 100 kg mixed retting 12 hours after sprinkling into the cassava base, then cultivate soil. This can make cassava late autumn leaves, extend the growth period, so that cassava grow fast and long, smooth skin, good quality, high yield.
