Problems solved by technology

However, none of these seedling substrates are suitable for macadamia seedlings
[0005] The peel and shell of macadamia nuts are the residues after the primary processing of macadamia nuts, and the branches and leaves of macadamia nuts are the waste after pruning in the orchard. Currently, they are usually disposed of by incineration or discarded, causing environmental pollution
However, the branches, leaves, peel and shell of macadamia nuts are rich in nutrients such as nitrogen nutrients and mineral elements, and have high utilization value, but so far there has been no relevant research on using macadamia nut waste as raw materials to prepare macadamia nut seedling substrates. to report

Embodiment 1

[0021] A method for preparing a macadamia seedling substrate based on macadamia waste, comprising the steps of:

[0022] (1) Preparation of fermented macadamia nut skins: Sprinkle the macadamia nut skins with water, add 2 kg of urea and 1 kg of decomposing bacteria agent for every 500 kg of macadamia nut skins, mix them evenly, and pile them up for anaerobic fermentation for 30 days. During the fermentation period, when the temperature in the pile exceeds 65°C, the pile should be turned in time until the surface of the peel turns from green to dark brown, and then dried in the sun to obtain fermented and decomposed macadamia nut peels;

[0023] (2) Preparation of carbonized macadamia nut shells: take dry macadamia nut shells, grind them and heat them below their ignition temperature to make them incompletely burnt, and then pass through a 10-mesh sieve to obtain carbonized macadamia nut shells;

[0024] (3) Preparation of macadamia nut branches and leaves powder: collect the p...

Embodiment 2

[0027] A method for preparing a macadamia seedling substrate based on macadamia waste, comprising the steps of:

[0028] (1) Preparation of fermented macadamia nut skins: Sprinkle the macadamia nut skins with water, add 3 kg of urea and 1 kg of decomposing bacteria agent for every 500 kg of macadamia nut skins, mix them evenly, and pile them up for anaerobic fermentation for 50 days. During the fermentation period, when the temperature in the pile exceeds 65°C, the pile should be turned in time until the surface of the peel turns from green to dark brown, and then dried in the sun to obtain fermented and decomposed macadamia nut peels;

[0029] (2) Preparation of carbonized macadamia nut shells: take dry macadamia nut shells, grind them and heat them below their ignition temperature to make them incompletely burnt, and then pass through a 10-mesh sieve to obtain carbonized macadamia nut shells;

[0030] (3) Preparation of macadamia nut branches and leaves powder: collect the p...

Embodiment 3

[0033] A method for preparing a macadamia seedling substrate based on macadamia waste, comprising the steps of:

[0034] (1) Preparation of fermented macadamia nut skins: Sprinkle the macadamia nut skins with water, add 2.5 kg of urea and 1 kg of decomposing bacteria agent per 500 kg of macadamia nut skins, mix well, and pile up for anaerobic fermentation for 40 days. During the fermentation period, when the temperature in the pile exceeds 65°C, the pile should be turned in time until the surface of the peel turns from green to dark brown, and then dried in the sun to obtain fermented and decomposed macadamia nut peels;

[0035] (2) Preparation of carbonized macadamia nut shells: take dry macadamia nut shells, grind them and heat them below their ignition temperature to make them incompletely burnt, and then pass through a 10-mesh sieve to obtain carbonized macadamia nut shells;

[0036] (3) Preparation of macadamia nut branches and leaves powder: collect the pruned macadamia ...

Abstract

The invention relates to a macadimia nut seedling raising substrate preparation method based on macadimia nut waste, and belongs to the technical field of agricultural production. The macadimia nut seedling raising substrate preparation method comprises the following steps that 1, fermented macadimia nut peel is prepared; 2, carbonized macadimia nut shells are prepared; 3, macadimia nut branch and leaf powder is prepared; 4, the prepared materials are mixed with peat soil and yellow heart soil to prepare substrates; 5, the substrates are placed in seedling raising bags for standby application after being mixed evenly. According to the macadimia nut seedling raising substrate preparation method based on the macadimia nut waste, waste such as pruned branches and leaves in a macadimia nut orchard and the peel and the shells generated in fruit primary processing can be effectively and reasonably utilized, the macadimia nut waste is prevented from polluting the environment, and the utilization value of the macadimia nut waste is improved; the substrates prepared through the method are rich in nutrition, loose and breathable and can retain water and fertilization, and root system development and plant growth of macadimia nut seedlings can be promoted; meanwhile, the preparation method is simple, low in cost and convenient to operate and transport.

Description

technical field [0001] The invention relates to a method for preparing a seedling-raising substrate, in particular to a method for preparing a macadamia seedling-raising substrate based on macadamia nut waste, and belongs to the technical field of agricultural production. Background technique [0002] Macadamia nuts, also known as Queensland chestnuts, Australian walnuts, and macadamia nuts, are native to Australia and belong to the family Longanaceae. Macadamia nuts are evergreen tree fruit trees. Its important nutritional value and health benefits enjoy the reputation of "Queen of Dried Fruits" and "King of Nuts in the World", and are deeply loved by people. my country introduced macadamia nuts in about 1910, but commercial planting did not begin until around 1980. At present, the planting scale has reached 65,200 hectares, mainly distributed in Yunnan, Guangxi, Guangdong, Guizhou, Sichuan, Hainan, Fujian and other provinces and regions. , The industry prospect is very bro...
