Micro-balancing ecological fertilizer special for castanea henryi and application

Abstract

The invention relates to a micro-balancing ecological fertilizer special for castanea henryi. The micro-balancing ecological fertilizer contains the following components in parts by weight: 30-50 parts of ecological organic fertilizer, 10-12 parts of humic acid, 1-2 parts of amino acid trace element chelate fertilizer, 0.1-0.2 part of alkali salt, 4.9-10 parts of turfy soil and 30-50 parts of chemical fertilizer. The micro-balancing ecological fertilizer special for castanea henryi, provided by the invention, is an organic-inorganic mixed fertilizer, is rich in humic acid, various amino acidsand trace elements, is a comprehensive multifunctional balancing ecological fertilizer, is capable of obviously promoting the growth vigor of the castanea henryi trees and is capable of increasing thefruiting rate of the castanea henryi so as to obviously increase the yield of the castanea henryi and achieve the purpose of increasing yield and income.

Description

technical field [0001] The invention belongs to the field of fertilizer production and preparation, and in particular relates to a special micro-balanced ecological fertilizer for chestnut and its preparation method and application. Background technique [0002] Chestnut (Castanea henryi (Skam) Rehd.et Wils.) Fagaceae. Deciduous tree, up to 30 meters, DBH up to 1 meter. Leaves alternate, ovate-lanceolate, 8-17 cm long, 2-5 cm wide, apex acuminate, base round, leaf margins serrated with awns. Male inflorescences produce lower leaf axils of branchlets, female inflorescences produce upper leaf axils of branchlets. The cupule is spherical, with thorns 2-3.5 cm in diameter; nuts are solitary in the cupule, ovoid. The flowering period is from May to July, and the fruiting period is from September to October. Widely distributed in the south of the southern slope of the Qinling Mountains and north of the Wuling Mountains, but not in Taiwan and Hainan. Born in hills and mountain...

AI Technical Summary

Problems solved by technology

[0013] However, there are almost no micro-balanced ecological fertilizers for chestnuts on the market. Most of them are single chemical fertilizers or a simple mixture of several main components. Fermentation continues after being applied to the land, and seedlings are burned, accompanied by different degrees of pests and diseases; the nutrient ratio is unscientific, resulting in different degrees of excess or lack of nutrients, resulting in imbalanced microbial flora, low bioavailability, and imbalanced soil structure (acidification, compaction, salinization, reduction of bacterial flora, excess of certain elements, etc.), resulting in an imbalance in the soil microenvironment

The above problems together lead to nutritional imbalance of chestnut, resulting in unhealthy growth of chestnut saplings and low quality of chestnut fruit, less fruit bearing, or even empty buds, which in turn leads to more frequent fertilization, high labor intensity, easy to burn seedlings, and low crop immunity. Severe pests and diseases, poor quality of chestnut fruit, serious consequences for growers not increasing income
