The cane shoots are rich in vitamin C, saccharides, amino acids, proteins and a certain amount of cellulose, have good taste and good taste, and are common vegetables.
The fertilizer amount required by the cane shoots in the growing period is large, and at present, an inorganic fertilizer or a common organic-inorganic fertilizer is usually applied. Inorganic fertilizer is singly applied, and the burning of the cane shoots is easily caused due to the high concentration of metal salt ions in the inorganic fertilizer; the common organic-inorganic fertilizer is singly applied, the nutrient content of organic matters in the fertilizer is low, the time required for decomposition and absorption is long, the fertilizer is greatly influenced by the environment, and the growth requirement of the cane shoot plant cannot be met.
The residual wastes of the traditional sugar production process contain a mixture of micromolecule sugar, lignan and humic acid, the mixture contains organic potassium and organic nitrogen, and the mixture is properly added into an inorganic fertilizer to form a low-concentration organic-inorganic compound fertilizer, so that the concentration content of metal salt in the traditional fertilizer can be reduced, the seedling burning phenomenon caused by fertilization can be effectively avoided, and the growth requirement of the wild rice shoots can be met. The residual wastes in the prior sugar production process are not fully recycled, thereby causing waste. The invention forms the special fertilizer suitable for the growth of cane shoots by recycling the mixture of micromolecular sugar, lignan and humic acid in the residual wastes of the prior sugar production process.
