Plant nutrient agent and use method thereof

Abstract

A plant nutrient is made from the following components with the weight percentages: 50%-100% of animal blood, 0-40% of ferrous sulfate, 0-10% of ferric sulfate, 0-2% of zinc sulfate, 0-2% of boracic acid, 0-2% of manganese sulfate, 0-10% of calcium superphosphate, 0-10% of potassium dihydrogen phosphate and 0-2% of copper sulfate. The application method of the plant nutrient is as follows: all the components are made into an aqua, paste or powder, and injected into plants by perforating holes on the plants. The plant nutrient of the invention has the advantages of available raw materials, simple processing, convenient and safe use as well as no environmental pollution, and the scattered animal blood is fully utilized. The plant nutrient is applicable to every growth and development period of the plants. By adding mineral substances needed by plants according to the growth and development situations of the plants, the efficiency of the plant nutrient can be enhanced, and the nutrient deficiency symptom of the plants can be prevented and treated. By adopting the plant nutrient during the transplant of big trees, the transplant survival ratio can be increased, and the recovery time of tree crowns can be greatly shortened.

Description

Technical field [0001] The invention relates to a nutrient, in particular to a plant nutrient and a method of use thereof. Background technique [0002] Like humans and animals, the growth of plants also requires nutrients. Plants with poor nutrient supply do not grow well, get sick easily and even cause death. Especially for some plants planted on barren land, for some fruit trees that need to increase fruit yield, and transplanted trees, special nutrition is required. The common method is to apply farmyard manure or chemical fertilizer, which is absorbed through the roots of plants. However, farmyard manure or chemical fertilizer is not a "nutrition" in itself. It must be absorbed by plants and then transformed into nutrients that promote plant growth through biochemical action. For some diseased trees or newly transplanted trees, this method is not good, and sometimes it has a negative effect. [0003] Animal blood is rich in nutrients and has the function of preventing and cu...
