Pear tree planting compound fertilizer

Abstract

The invention discloses a pear tree planting compound fertilizer in the field of agricultural planting, which comprises components with parts by weight: dried dung 50-70 parts, rape seed cakes 25-35 parts, soybean cakes 25-30 parts, ammonium bicarbonates 3.5-6.5 parts, urea 3.5-4 parts, dihydrogen phosphate fertilizers 1-2 parts, vinasse powder 1.5-2.5 parts, fruit setting ichors 0.8-1.7 parts, calcium sulfate 0.6-2.6 parts, ferrous sulfate 0.7-2.5 parts and zinc sulfate 0.4-2.5 parts. The pear tree planting compound fertilizer combines inorganic fertilizers and organic fertilizers, perfectly meets the growth demands of pear trees, and is used to plant the pear trees. The inorganic fertilizer and organic fertilizer can improve fruit setting rate and yield of the pear trees, is long in fertilizer efficiency, and does not have pollution to soils.

Description

technical field

[0001] The invention relates to the field of agricultural planting, in particular to a compound fertilizer for pear tree planting. Background technique

[0002] Pear trees are perennial woody plants with strong branch skeletons and the characteristics of storing nutrients. Pear trees have well-developed root systems and deep and wide distribution. 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 deficiency diseases. . Therefore, carrying out fertilization management to pear tree is one of important link in the pear tree planting.

[0003] At present, when people fertilize pear trees, they generally use inorganic fertilizers such as manure and bean cakes. Although they can also increase production to a certain extent, the various nutrients in the fertilizers are far...
