Organic fertilizer for blueberry tree

Abstract

The invention discloses organic fertilizer for a blueberry tree. The organic fertilizer is prepared from 20-30 parts by mass of chicken manure, 30-40 parts by mass of colleseed oil cake, 5-10 parts by mass of rice bran, 15-20 parts of deciduous leaves and 3-5 parts of zeolite powder. A preparation method of the organic fertilizer comprises crushing colleseed oil cake to obtain fine particles, stirring chicken manure, the colleseed oil cake particles, rice bran and deciduous leaves, compacting the mixed fertilizer, covering and sealing the compacted fertilizer through a plastic film, arranging drainage ditches around the compacted fertilizer, carrying out fermentation for 40-60 days and adding zeolite powder of 40-100 meshes into the fermented fertilizer according to the above mass ratio. The organic fertilizer can guarantee comprehensive flowering in a blueberry orchard and general fruit setting, realize plump and smooth-skinned fruits and improve a yield and fruit taste and flavor. Through the organic fertilizer, eco-friendly, healthy and organic blueberries are obtained. The organic fertilizer realizes soil improvement and improves soil properties year by year.

Description

Technical field [0001] The invention relates to an organic fertilizer, in particular to an organic fertilizer for blueberry fruit trees. Background technique [0002] Blueberry (VaccimiumSPP.), also known as blue berry, edulis, bilberry, belongs to the genus Vaccinium of the azalea family, is a perennial deciduous evergreen woody shrub.

Problems solved by technology

At present, the fertilization of blueberries is mainly based on chemical fertilizers, and the use of chemical fertilizers for a long time will cause soil quality to deteriorate. In order to develop environmentally friendly, healthy, green, and organic blueberry food, the use of farmyard manures is gradually increasing. However, the single farmyard manure contains Nutrient elements are limited and cannot meet the needs of blueberry growth
