Pay attention to the selection of commodity organic fertilizer first to clarify the source of raw materials, followed by the selected commodity organic fertilizer first small area test demonstration. Pay attention to the use of most of the organic fertilizers such as newly purchased chicken manure, cow dung, and other harmful substances that often contain pathogens, such as direct use of the disease, should be stacked after fermentation. Pay attention to the amount of fertilizer to be controlled. Organic fertilizer has a large volume and low nutrients. It needs a large amount of application to meet the needs of crops, but not as much as possible. Fruit crops require large amounts of fertilizer, generally about 2000 kg. Note that the organic and inorganic organic fertilizers are all in the nutrient, but when the crop grows and needs fertilizer peaks, the supply is often insufficient; inorganic fertilizers are easily decomposed and are conducive to crop absorption, but their stamina is not sufficient. Organic fertilizers and inorganic fertilizers can be used together to meet the fertilizer requirements of crops. Pay attention to the long-term application of basal fertilizer as the main organic fertilizer with long-lasting effect and slow release of nutrients. Generally, it is used as a basal fertilizer. Applying organic fertilizer during deep ploughing will facilitate the integration of soil and fertilizer, promote the formation of soil aggregate structure, and effectively improve soil properties. The use of bio-fertilizers for biological fertilizers can accelerate the decomposition of organic matter in organic fertilizers, and can also decompose and transform harmful organic matter. Generally, when organic fertilizer is used as the base, 150-200 kg of biological fertilizer can be applied per acre, and when applied as top dressing, 20-25 kg can be applied per acre.
