Special fertilizer for apple trees

Abstract

The invention relates to a special fertilizer for apple trees. The special fertilizer is prepared from the following components in parts by weight: 35-45 parts of dry sheep manure, 25-30 parts of bean cakes, 15-20 parts of rapeseed cakes, 3.7-6.7 parts of ammonium bicarbonate, 3.6-4 parts of urea, 1.2-1.8 parts of potassium dihydrogen phosphate fertilizer, 1.6-2 parts of distiller grain powder, 1.5-2 parts of carbendazim, 0.7-1 part of paclobutrazol, 0.6-1 part of fruit tree spotting agent, 1-2 parts of calcium carbonate, 0.7-1.5 parts of liquid fruit setting agent, 0.5-2.5 parts of calcium sulfate, 0.5-2.0 parts of ferrous sulfate and 0.5-2.4 parts of zinc sulfate. The contents of nitrogen, phosphorus and potassium in the special fertilizer provided by the invention are suitable for the growth of apple trees and apples, and the efficacies of all the elements can be sufficiently exerted; meanwhile, the organic matters and trace elements which are required by the growth of plants are also added into the fertilizer, so that the yield of the apples can be increased on a large area, and the quality of the apples can be improved on a large area; in addition, the raw materials are easily obtained, the preparation method is simple, the cost is low, not only is the yield of the apple trees increased, but also the problem that the applies are small in size, light in weight, slow in growth and easy to induce diseases is solved, and a new though is brought for cultivating the apple trees.

Description

technical field [0001] The invention belongs to the technical field of fertilizers for fruit tree cultivation, and relates to a fertilizer for apple trees, in particular to a special fertilizer for apple trees. Background technique [0002] Fruit trees are perennial woody plants with strong branch skeletons and the characteristics of storing nutrients. The root system of fruit trees is well developed, and the distribution is deep and wide. Once they have been planted for many years, they will selectively absorb nutrients from the same soil for a long time, which will easily lead to insufficient supply of soil nutrients, and physiological obstacles such as nutritional disorders and deficiencies. Therefore, carrying out fertilization management to fruit trees is one of important links in fruit tree cultivation. At present, when people fertilize apple trees, they generally use manure, bean cakes, urea, etc. to fertilize. Although they can also increase production to a certain ...

Problems solved by technology

At present, when people fertilize apple trees, they generally use manure, bean cakes, urea, etc. to fertilize. Although they can also increase production to a certain extent, the various nutrients in the fertilizers are far from reaching the level of apple trees. The nutritional needs of the apple tre
