Cassava, not sweet potatoes, not purple potatoes. I think it’s more like ginseng. Farmers grow cassava, either to eat or to sell, but how can they grow better and better quality than others? Start with cassava fertilizer!
Cassava is coarse and easy to grow, and does not require high soil conditions, as long as it is not overly barren and too much gravel, not water can be planted. Cassava is an important raw material for aquaculture and starch processing. Although cassava is crude and easy to grow, scientific planting and management are also necessary to ensure a high level of yield.
1. Deep tillage and sufficient base fertilizer: 500 ~ 800kg farm manure or compound fertilizer of 3 yuan per mu (25kg) is applied as base fertilizer, laying a good foundation for seedling emergence and long potato.
Mulching cultivation: on the plowed and raked land, the furrow was planted according to row spacing and applied to the base fertilizer. The furrow surface was covered with mulch, and the mulch was compacted with soil around the mulch. Then, the stem segments of cassava were inserted on both sides of the furrow membrane or small holes were made in the furrow membrane to insert the seed stem, and the seed stem was exposed 3 ~ 5cm to the furrow surface.
Formula fertilization: formula fertilization is one of the key technologies for high yield of cassava. Cassava has the growth characteristic of likes nitrogen, likes potassium, accordingly, should notice fertilizer collocation in each growing season. Generally, it is 25kg of three-yuan compound fertilizer per mu of base fertilizer; After planting, the seedling height was about 20cm and the seedling fertilizer was applied with 0 ~ 15kg of urea and potassium chloride in each mu to promote the growth and thickening of the seedling. Add potato fertilizer, apply 15kg of potassium chloride on an acre, and increase the number of potatoes to promote the expansion of potato. If it is cultivated with plastic film, the fertilizer amount should be applied at one time, and the fertilizer amount should be 25kg of compound fertilizer and 25kg of potash fertilizer. 4. Timely planting and thinning: after 3 to 5 weeks of cassava planting, the plants are absent due to the poor quality of a small number of stems or the discomfort of the small environment after planting, so the plants should be replanted in a timely manner to preserve the seedlings. After the seedlings are unearthed, multiple seedlings often grow out of the same stem. When the seedling height is 15-20cm, the seedlings will be planted with multiple seedlings.
3. Weeding under tillage. When the seedling grows to about 20 cm long, it should be weeded and loose soil, and the grass should be removed to mud around the root. When the seedling grows to 1 meter long, undertake second weed, loosen soil, but do not hoe break fries.
Insect pest control and rat control. Tigers like to steal cassava when it first appeared. A tigress can eat a seedling in one night. To long potato period, rats will steal the potato eat, should be timely anti-rodent measures.
