What should be noted in cassava cultivation? Here is an introduction.The following points should be noted in cassava cultivation:
1. Deep plowing to improve the soil:One month before planting cassava, first plow the land and let it sun-bleach so the soil is fully weathered. At planting time, apply 250-300 kg per mu of phosphate fertilizer composted and rotted with poultry and livestock manure as a base fertilizer.
2. Select good varieties:Be sure to choose varieties that produce many tubers, have low toxicity, and give high yields. Also select middle and lower stem sections that are thick, have close nodes, and are free of pests, diseases, and damage as seed stems.
3. Seedling treatment:Before planting, cut seedlings 33 cm long, and cut the lower end into a slanted opening 3-6 cm long, shaped like a duck bill.
On both sides of the seed stem above the slanted opening, make alternating partial cuts through the stem bark every 2 nodes, severing the cambium in 2-3 places. The cut should be 1/4 of the circumference of the seed stem and 2 cm long. This can make the slanted opening and the places where the cambium is severed produce more roots and tubers.
When planting, adopt the method of controlling axillary buds to grow at fixed nodes. Apart from leaving the axillary buds at the top three nodes of the seed stem, remove the axillary buds at all other nodes, and change slanting insertion to horizontal insertion. This can control the growth of one ideal, robust main stalk plant.
4. Directed fertilization by stages:After planting, when the seedlings grow to 12-15 cm, carry out the first fertilization, applying 30 carries per mu of dilute manure water.
In addition to applying it appropriately below the seedling roots, focus on applying it in the surrounding area about 40 cm from the seedlings to promote more rooting and rapid spreading. When the cassava seedlings grow to 50 cm, apply the second fertilizer, using 40-50 carries per mu of high-quality manure water mixed with 8-10 kg of urea, applying the fertilizer in the surrounding area 50-60 cm from the plants so the cassava roots spread along the surface soil plow layer. When the cassava seedlings grow to 70-100 cm, choose a sunny noon to pinch the tops, removing 3-5 cm of the growing point. Then apply 60 carries per mu of manure water plus 10-12 kg of urea, to encourage more branches to grow.
5. Loosen the soil and apply heavy fertilizer in autumn:After autumn begins, choose a sunny day and use a sharp hoe to scrape away the soil on one side of the base (be careful not to damage the tubers) to expose the tubers, let the soil sun for 4-5 hours, then apply 30 kg per mu of ammonium bicarbonate plus 100 kg of phosphate fertilizer, mix and compost for 12 hours, then scatter it into the cassava base, and then earth up.
In this way, cassava will not shed leaves in late autumn, the growth period is extended, and the cassava grows fast and long, with smooth skin, good quality, and high yield.
