Compound fertilizer capable of applying in annual Corylus heterophylla fisch forest

Abstract

The invention belongs to the field of compound fertilizers, and specifically relates to a compound fertilizer capable of applying in annual Corylus heterophylla fisch forest. The compound fertilizer comprises, in parts by weight, 10 to 25 parts of a nitrogen fertilizer, 8 to 15 parts of a phosphorus fertilizer, 12 to 16 parts of a potassium fertilizer, 2 to 6 parts of magnesium sulfate, 2 to 7 parts of medical stone, 5 to 11 parts of urea, 12 to 30 parts of straw powder, 2 to 5 parts of eggshell powder and 12 to 21 parts of rice bran.

Description

technical field [0001] The invention belongs to the field of compound fertilizers, in particular to compound fertilizers applicable to annual hazel forests. Background technique [0002] Hazelnut tree (scientific name: Corylus heterophylla Fisch.): also known as hazelnut, one of the four major dried fruits (walnuts, almonds, hazelnuts, cashews) in the world. It is a shrub or small tree of the genus Corylus in the Betaceae family, with gray bark; dark gray branches, glabrous; leaves oblong or broadly obovate, with concave or truncated apex, triangular-shaped apex in the center, and irregular heavy edges Serrate; petiole sparsely covered with short hairs or nearly glabrous; male inflorescence solitary; fruit buds campanulate, densely pubescent and sparsely villous, upper part lobed, lobes triangular, margin entire; peduncle dense Covered with pubescence. Nuts subglobose, glabrous or only sparsely villous at the top. [0003] In recent years, with the increase in market dema...
