Winter is a cold season, a dry season, a leaf colorful desolate lonely season, wheat just bud was surrounded by winter. When next spring comes, irrigation, fertilization, spraying and other measures are needed. Fertilizer is important for early growing crops. The main function of chemical fertilizer is to provide nutrients for crops, enhance the ability of cold and disease resistance, and achieve healthy growth.
Experts say functional fertilizer is a new type of fertilizer, but it is not a new term, nor is it a new thing. Functional fertilizer has been approved by dealers and farmers in local markets. For example, adding effective silicon and calcium into compound fertilizer can promote the thickening and elasticity of stem wall, and improve the mechanical strength and lodging resistance of rice stem. Although functional fertilizer is no longer a new thing, but the demand for crops is strong, the development of new characteristics.
The future development of waste materials and the focus of plant nutrition research should not only focus on nutrient content, but also attach importance to nutrient form and its scientific collocation. Meanwhile, the transformation of different nutrient forms, absorption and transformation of auxiliaries and the ability of utilization and absorption of fertilizers should also be studied.
