Shandan "controls, replaces, refines and unifies" promotes reduction of fertilizers and pesticides and increases efficiency

Shandan County has adopted four technical means of "control, replacement, refinement, and integration" to vigorously demonstrate and promote the fertilizer reduction and efficiency technology based on "bio-organic fertilizer + formula fertilizer + mechanical deep fertilization" and "disease resistance and detoxification".
Seed potato + fitness cultivation + green prevention and control + scientific prevention and control" pesticide reduction and efficiency technology, comprehensively promote the implementation of fertilizer and pesticide reduction and efficiency technology
.
Focusing on "control", carry out dual control of fertilizer and medicine
.
Formulated fertilization and formula application according to factors such as soil type, soil fertility grade, crop type, yield level, occurrence of diseases and insects, strictly control the type and amount of chemical fertilizers and pesticides used, reduce unreasonable fertilization by more than 20 kg, and reduce repeated application 50 Grams
.
Focusing on "replacement", promote fertilizer and medicine substitutes
.
Carry out demonstration work such as replacing some chemical fertilizers with organic fertilizers, replacing traditional fertilizers with slow-release fertilizers, and replacing chemical pesticides with biological pesticides, and realize a new practical model of chemical fertilizers and pesticides that combines organic and inorganic, and biochemical combinations
.
Focus on "precision" and strengthen the monitoring and early warning of pests and diseases
.
Achieve precise monitoring and early warning, precise prevention and control timing, and fine pesticide application technology to gain the initiative in time for the prevention and control of major diseases and pests, and the damage of pests and diseases is controlled to a minimum
.
Focusing on "unification", vigorously promote the unified prevention and control of crop diseases and insect pests
.
By supporting specialized prevention and control organizations, large professional households, and farmers' cooperative organizations, we will actively promote the integration of unified prevention and control and green prevention and control, and effectively give full play to the high efficiency and environmental protection advantages of professional unified prevention and control, reduce the use of pesticides, and enhance the effectiveness of prevention and control
