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...

Problems solved by technology

[0003] In recent years, with the increasing market demand for hazelnuts, a large amount of hazelnuts needs to be supplied to the market, so it is necessary to increase the output of hazelnuts. However, while increasing the output, the quality of hazelnuts must also be ensured. It is easy to master, and at the same time, the current fertilizer has a large nutrient loss, and the effect of increasing production and improving quality is not obvious
