Organic fermented fruit tree fertilizer and preparation method thereof

Abstract

The invention provides an organic fermented fruit tree fertilizer, which comprises a base fertilizer and a leaf fertilizer, the base fertilizer comprises the following components by weight: 2800-3200g of an organic fertilizer, 250-300g of urea, 150-200g of monoammonium phosphate, and 150-200g of potassium chloride, the foliar fertilizer is prepared from the following components in percentage by weight: 10 to 15 percent of urea, 3 to 5 percent of monopotassium phosphate, 0.3 to 0.5 percent of agricultural chitosan oligosaccharide, 0.1 to 0.2 percent of 6-BA, 0.1 to 0.2 percent of paclobutrazol, 1 to 2 percent of triadimefon, 3 to 5 percent of polyethylene glycol, 0.1 to 0.2 percent of sodium tetraborate, 0.01 percent of copper sulfate, 0.03 percent of ferrous sulfate, 0.03 percent of zinc sulfate, 0.01 percent of manganese sulfate, 0.02 percent of magnesium chloride and the balance of water. After the fertilizer is applied, beneficial bacteria in soil are increased, nitrogen is fixed, phosphorus is dissolved, the soil is activated, the water-retaining property, the fertilizer utilization rate and the fertilizer persistence of the soil are improved, and the effect of controlled release of the fertilizer can be achieved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organically fermented fruit tree fertilizer and a preparation method thereof. Background technique [0002] Fruit trees are important economic crops. Fertilizers play an important role in improving the yield and quality of fruit trees, which directly affects the income of fruit farmers. At present, the fertilizers applied to fruit trees are organic fertilizers, chemical fertilizers and foliar fertilizers. The correct use of fruit tree fertilizer is one of the key links in the production of pollution-free fruit. The national agricultural industry standard promulgated and implemented by the Ministry of Agriculture has also made clear regulations on the use of fertilizers for the production of green food (fruit), requiring the principle of fertilization to be based on organic fertilizers, supplemented by chemical fertilizers, to maintain or increase soil fertility and soil microorganisms active....
