Abstract

The invention discloses a fertilizer suitable for Loess Plateau area full-fruit-period early-bearing walnut trees; the fertilizer includes an inorganic fertilizer, an organic fertilizer and a foliar fertilizer, wherein the inorganic fertilizer contains the components of nitrogen (N), phosphorus (P2O5), potassium (K2O), zinc (Zn) and iron (Fe) with the mass ratio of (2-3):(0.5-1):(2-3):(0.03-0.06):(0.03-0.06); the organic fertilizer contains cured animal manure; the foliar fertilizer contains 5-aminolevulinic acid. The invention discloses a fertilizer application method comprising the steps: applying the inorganic fertilizer for 3 times; applying the organic fertilizer in a leaf falling period of the walnut trees; and spraying the foliar fertilizer in a period from a flower falling period of the walnut trees to a walnut hardening period of the walnut trees. After the walnut tree fertilizer is applied, the walnut tree fertilizer can promote tree reproductive growth, improves yield, increases the single fruit weight, the kernel generation rate and the crude fat content, and can increase the chlorophyll content of leaves.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer suitable for early-fruiting walnut trees at the full fruit stage in the Loess Plateau region and a fertilization method thereof, especially suitable for 8-25-year-old early-fruiting walnuts in the Loess Plateau region. Background technique [0002] In early-fruiting walnut orchard fruit tree cultivation technology, fertilization is one of the important ways to improve walnut yield and quality. In recent years, a large number of special fertilizer products for walnut trees have come out, such as the "Qinyang" brand walnut tree fertilizer jointly developed by Shaanxi Shangluo Walnut Research Institute and Luonan Qinfeng Chemical Co., Ltd.; Hickory tree fertilizer, "Yunhe brand" walnut tree fertilizer produced by Shandong Runhe Fertilizer Chemical (Group) Co., Ltd., special fertilizer for walnut chicken manure produced by Shijiazhuang Fendou Fertilizer Technology Co., Ltd., e...
