Culture medium for rapidly cultivating temporary planting seedlings of bananas

Abstract

The invention relates to a cultivation medium, particularly to a culture medium for rapidly cultivating temporary planting seedlings of bananas, and belongs to the technical field of temporary planting. The cultivation medium mainly comprises a Pleurotus eryngii fermentation material, latosol and river sand, wherein a volume ratio of the Pleurotus eryngii fermentation material, the latosol and the river sand is (6-10):(0.5-2):1. The Pleurotus eryngii fermentation material is obtained by processing Pleurotus eryngii wastes with a method comprising the following steps: taking the Pleurotus eryngii wastes out of Pleurotus eryngii cultivation bags; crushing into particles with a particle size of 0.12-0.30 cm; adding water for moisturizing; placing into a fermentation tank; adding active bacteria for fermentation; drying in the sun until the water content is 15-20% after completing fermentation; and finally, crushing into the particles with the particle size of 0.24-0.42 cm, namely, the Pleurotus eryngii fermentation material. The cultivation medium provided by the invention makes full use of the Pleurotus eryngii wastes to solve hidden dangers of processing the Pleurotus eryngii wastes and cultivate the temporary planting seedlings of banana, thereby achieving a purpose of turning wastes into treasures.

Description

technical field [0001] The invention relates to a cultivation substrate, in particular to a cultivation substrate for rapidly cultivating banana pseudo-planting seedlings, and belongs to the technical field of pseudo-planting. Background technique [0002] Banana is an important economic crop in the subtropical zone, with a planting area of ​​about 300,000 hm 2 , up to 200 million banana tissue culture seedlings are needed every year. Before the banana tissue culture seedlings are applied to the field cultivation, they must undergo false planting and early matching, which is called the cultivation of secondary seedlings or secondary seedling cultivation or false planting cultivation. The cultivation technology of secondary seedling cultivation is very important, especially in In the current situation of the raging and flooding of banana Panama wilt, it has been found that the backward cultivation technology of banana pseudo-plants is one of the reasons for the proliferation...

AI Technical Summary

Problems solved by technology

The nutrient soil prepared in this way is likely to bring many problems: first, the soil collected nearby will inevitably carry pathogenic bacteria and nematodes (Panama pathogens are soil-borne fungi), and generally the soil and substrate are not disinfected, so this substrate is not only unsafe , and often leads to the process of cultivating secondary seedlings as a process of banana Panama disease infection and transmission; secondly, the nutrient-soil nutrient distribution ratio is unreasonable, and the substrate composition ratio is unreasonable, which is manifested in that the ratio of nitrogen, phosphorus and potassium nutrients is not suitable for bananas. The growth of seedlings is either rich or lacking in nitrogen, the substrate is either heavy or sandy, has poor permeability or does not retain water and fertilizer, and the water, fertilizer, air and heat are not coordinated, and the survival rate is low, with an average of only about 70%.

The 3rd, can bring two obvious problems again when the secondary seedling that is based on soil is transplanted out of the nursery, one is that the weight of each bag of seedling plus substrate can reach about 1 kilogram, so the transplanting process just needs a large amount of labor and strong This is extremely disproportionate to the shortage of surplus labor in today's rural areas. In production practice, banana seedlings are required to be healthy, cup seedlings and light; secondly, the soil matrix seedlings do not cause root damage during transplanting and bag removal, so banana transplanting After planting, it generally takes 15-30 days to slow down the seedlings in the field according to the transplanting period, which obviously delays the time to market of bananas and reduces the economic benefits of bananas
