At present, China's cassava industry is developing rapidly, but it still encounters some problems, such as low cassava yield, low starch content, unreasonable maturity of varieties, extensive planting, low investment, unscientific cultivation, low economic efficiency, and high yield and efficient production of cassava. The area for technology promotion is small, and the cassava cultivation technology level needs to be further improved. Moreover, the cassava processing enterprises have a shortage of raw materials, discontinuous production, and poor efficiency, which are also important factors restricting the development of the cassava industry. Therefore, it is of far-reaching significance to study the high-yielding, high-efficiency cultivation techniques of cassava, improve the overall technical level of cassava cultivation, improve the production efficiency of processing enterprises, and promote the development of cassava industry.
1. Cassava deep plowing and deep-sown technology: deep plowing and deep plowing of the soil with a subsoiler will enable the soil to be transported without turning, maintaining the structure of the plow layer, which will help the soil to retain water and fertilizer, improve the drought resistance of the cassava, and promote the expansion of the tubers.
2. Change the habits of planting methods: Promote the use of mulching mulching film stems flat insert method. The mulching mulching stems can be seeded quickly and neatly, with high emergence rate. The seedlings can be grown 15 to 20 days faster than the customary ditching method. The emergence rate is more than 5 percentage points higher, and the seedlings are neat and make the soil loose. , It is conducive to the expansion of tubers and harvesting of fresh potatoes.
3. Cassava stalk crushing technology: According to testing, cassava stalks are rich in nitrogen, phosphorus, potassium and other nutrients and organic matter. The cassava culm smashing and returning to the field not only solves the problem of cassava stalks piled up, but also can improve the soil structure of the arable land, increase soil organic matter and nutrient content, and turn waste into treasure.
4. Increase fertilizer input to further increase land productivity and economic benefits.
