Scientific promotion of organic fertilizer is an important measure to achieve the goal of “one control, two reductions and three basics†agricultural non-point source pollution control. Recently, the Provincial Agricultural Committee issued the “Action Plan for Organic Fertilizer Substituting Fertilizer for Fruit and Vegetable Tea in Anhui Provinceâ€. According to the actual situation of our province, different technical models for replacing fertilizer with organic fertilizer were proposed for tea, facility vegetables and fruit trees to enhance the quality of agricultural products. Reduce the use of chemical fertilizers and clean the rural environment.
Our province is a large tea-producing province. However, for a long time, the application of organic fertilizer is insufficient and the application method is single, which has aggravated the poor soil, lack of nutrients and acidification of tea gardens, which seriously restricts the development of the tea industry. The three technical models for promoting organic fertilizer instead of chemical fertilizer in the tea producing areas are:
The first is the "organic fertilizer + formula fertilizer" model. Promote formula fertilization, increase organic fertilizer, and reduce the amount of chemical fertilizer.
The second is the “tea-marsh-animal†model. In the tea-producing areas, relying on planting large households and professional cooperatives, and supporting large-scale biogas facilities, the biogas slurry will be applied to tea gardens.
The third is the “organic fertilizer + water and fertilizer integration†model. While increasing the application of organic fertilizer, the integration of water and fertilizer technology will be promoted to improve the efficiency of water and fertilizer use.
The facility has a long production cycle and high yield. The fertilizer is large, the fertilization structure is unreasonable, the partial nitrogen fertilizer is serious, and the secondary salinization of the soil is prominent. Promote the replacement of chemical fertilizers with organic fertilizers and promote three technical models in the advantageous production areas of facility vegetables:
The first is the "organic fertilizer + formula fertilizer" model. Promote formula fertilization, increase organic fertilizer, and reduce the amount of chemical fertilizer.
The second is the “vegetable-marsh-animal†model. Relying on planting large households and professional cooperatives, it will cooperate with large-scale breeding to establish large-scale biogas facilities and apply biogas slurry to facility vegetables.
The third is the “organic fertilizer + water and fertilizer integration†model. While increasing the application of organic fertilizer, the integration of water and fertilizer integration technology, the focus is to promote drip irrigation, micro-spraying and other technologies to improve water and fertilizer use efficiency.
The orchards in our province are mainly distributed in the old road of the Yellow River and the hilly mountainous areas. The soil fertility is low, the texture is poor, and the soil erosion is serious. Driven by the pursuit of production and other factors, the production of fruits is often re-applied with chemical fertilizers and light organic fertilizers, further reducing the soil. Fertility affects the quality of the fruit. Promote the replacement of chemical fertilizers with organic fertilizers and promote four technical models in key fruit producing areas:
The first is the "organic fertilizer + formula fertilizer" model. In areas rich in organic fertilizer resources such as livestock and poultry manure, large-scale planters and professional cooperatives are encouraged to concentrate on the use of compost to reduce the amount of chemical fertilizer. Combine soil testing and formula fertilization to promote commercial organic fertilizer in urban orchards.
The second is the “fruit-marsh-animal†model. Relying on planting large households and professional cooperatives, it will cooperate with large-scale breeding to establish large-scale biogas facilities, and apply biogas slurry to orchards to reduce the amount of chemical fertilizer.
The third is the “organic fertilizer + water and fertilizer integration†model. In the production areas with good water and fertilizer conditions and new orchards, the dwarf and dense planting will be promoted, and the application of organic fertilizer will be promoted, and the water and fertilizer integration technology will be promoted to improve the efficiency of water and fertilizer utilization. The fourth is the “natural grass + green manure†model. In areas where water and heat conditions are appropriate, cover the soil with natural grass or green manure, reduce exposure, prevent soil erosion, and fertilize soil.
