Embodiment 1

[0026] Example 1 Variety: Mibao Red Pitaya

[0027] A cultivation method for reducing pitaya root rot, comprising the steps of:

[0028] Step 1: Preparation of the cultivation medium of potted dragon fruit

[0029] Step 2: Potting Substrate Recipe:

[0030] Commodity chicken manure organic fertilizer (N-P 2 o 5 -K 2 O>5% organic matter>45%) 2%+straw biochar 2%+bacteria residue 6%+90% mountain red loam (m / m, mass ratio),

[0031] Put the mixed material prepared according to the potting substrate formula above into a potting container with a size of 50cm (Φ)*40cm (H).

[0032] Step 3: Post Substrate Recipe:

[0033] (1) Straw biochar 20% + commercial chicken manure organic fertilizer (N-P 2 o 5 -K 2 O>5% organic matter>45%) 15% + volcanic rock (particle size about 1cm) 6.88% + fungal residue 58.12% (v / v, volume ratio, large pores)

[0034] (2) Straw biochar 35% + commercial chicken manure organic fertilizer 15% + volcanic rock 20% + fungal residue 30% (v / v, volume rati...

Abstract

The invention relates to the field of dragon fruit cultivation, in particular to a cultivation substrate and method for reducing dragon fruit root rot diseases and promoting growth. The cultivation substrate comprises straw biochar and microbial residues in a conventional substrate. The to-be-achieved effect of the invention is to provide a cultivation substrate and method for reducing dragon fruit root rot diseases and promoting growth. The cultivation substrate is green and free of pollution, the cultivation method is simple. The cultivation substrate has a relatively smaller bulk density and loose texture, and facilitates the root growth. The porous structure of the straw biochar can delay the release of nutrients, increases the utilization rate of fertilizers, and also plays a better role in reducing the dragon fruit root rot diseases. The cultivation method is simple and easy to perform, does not require specific fertilization management, and facilitates industrial popularization.

Description

technical field [0001] The invention relates to the field of pitaya cultivation, in particular to a cultivation substrate and a cultivation method for reducing pitaya root rot and promoting growth. Background technique [0002] The root system of pitaya is shallow and weak, and root rot is prone to occur in production management. Root rot is a disease caused by a fungus that causes the roots to rot, the ability to absorb water and nutrients is gradually weakened, and finally the whole plant dies. Pitaya root rot has the characteristics of rapid onset, rapid spread, and severe damage. In severe cases, it can lead to a substantial reduction in production, and even the death of seedlings in the entire garden. There are many factors that cause root rot of dragon fruit, mainly including: excessive watering and frequent application, too thick fertilization, too deep planting, underground pests, mechanical damage, and application of immature organic fertilizers. Pitaya root rot c...
