Preparation method of semi-matrix fertilizer for cultivation of dragon fruit

Abstract

The invention discloses a preparation method of semi-matrix fertilizer for cultivation of dragon fruit. The preparation method includes: subjecting eucalypt bark and fibrous materials to primary crushing prior to mixing to obtain coarse raw materials; spraying fermented liquid in the coarse raw materials and adding water to obtain raw materials; subjecting the raw material to secondary fermentation to obtain fermented materials; subjecting the fermented materials to secondary crushing to obtain sieved materials; adding organic ingredients to the sieved materials to obtain the semi-matrix fertilizer. Phenolic compounds in eucalypt bark are degraded through the fermentation technology, the problem about low resource utilization level of the eucalypt bark is solved, the property of the semi-matrix fertilizer prepared by taking the eucalypt bark as the main raw materials is between bio-organic fertilizer and matrix fertilizer, the semi-matrix fertilizer is a new product having the advantages of the matrix fertilizer which does not burn roots and promotes the roots and seedlings and the bio-organic fertilizer capable of promoting growth, resisting disease and improving soil, and efficient resource utilization and environment protection are highlighted.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting. More specifically, the present invention relates to a kind of preparation method of pitaya plantation semi-substrate fertilizer. Background technique [0002] The root system is a necessary organ for plants to fix on the surface and absorb water and inorganic salts from the soil. The quality of root system growth and development determines the product and quality of the above-ground parts, especially harvested organs, and also determines the absorption of nutrients by plants. and utilization efficiency. The root system of dragon fruit is mainly distributed in the surface soil layer, which is aerial root, with well-developed horizontal root system and extremely vigorous vitality. However, the root system of dragon fruit is weak and slender, easy to break when injured, and easy to rot due to poor air permeability. The root system is easy to entangle with weed roots in the surface so...

Problems solved by technology

However, the root system of dragon fruit is weak and slender, easy to break when injured, and easy to rot due to poor air permeability. The root system is easy to entangle with weed roots in the surface soil layer, making it difficult to clean and apply pesticides. Root system characteristics of seedlings. Improper application of traditional fertilizers, chemical fertilizers or organic fertilizers for dragon fruit planting can easily cause root burn and root damage, and root protection and weed resistance are not strong in guiding root growth.

[0003] Due to the characteristics of dragon fruit, root protection has become a technical problem. In order to protect the root system of dragon fruit planting, there are roughly several current methods: one is to cover the roots with straw to prevent weeds, but the straw is perishable and airtight, and it is easy to breed bacteria. If the roots are rotten, the effect is counterproductive; the second is to cover the roots with raw eucalyptus bark, which is low in cost and strong in air permeability, but raw eucalyptus bark contains a special phenolic allelochemical, which will inhibit the growth and development of the root system of crops, and it is easy to attract some such as Millipedes (also known as millipedes) suffer from shade-loving pests, which cause root damage; other methods such as peanut shells, dregs, straw, bagasse, etc. cover not only fail to protect the root system, but also bring problems such as insect pests, germs, and root damage.

[0004] With the development of new agriculture, semi-substrate fertilizers are replacing the use of chemical fertilizers in farmland due to their advantages of stable performance, rich nutrition and less pollution, so as to protect the organic matter in the soil, reduce the pollution of groundwater sources and rivers, and avoid causing aquatic plants The excessive growth of algae and algae deteriorates the water quality; as the most commonly used organic substrate, peat is widely used in production, but it is a non-renewable resource with high production costs, and it is necessary to find sustainable alternative resources to reduce production costs
