Problems solved by technology

Rhododendron likes acidic soil, and most urban cultivation soils in my country cannot meet its growth needs, so peat with weakly acidic pH has become the most used substrate in rhododendron cultivation; however, peat, as a non-renewable natural resource, Excessive mining will lead to the destruction of wetland environment

Embodiment 1

[0026] (1), 4 parts of peat, 4 parts of mushroom mud, 5 parts of rice bran and 3 parts of wheat straw are mixed and naturally retting for 30 days;

[0027] (2) Take 4 portions of cornstarch residue and pour them into the fermentation tank, add the same weight of hot water at about 60°C and mix well, wait until the temperature is naturally cooled to 32±2°C, stir properly during this period to prevent precipitation, and then sprinkle the yeast evenly Stir the yeast evenly, add 133.33g per 100kg of cornstarch residue, control the temperature between 28-36°C, stir twice a day for the first 3 days after adding the yeast, and sprinkle acetic acid bacteria after 7 days of anaerobic fermentation. The amount of acetic acid bacteria added is 6.67g per hundred kilograms of cornstarch residue, stirred evenly, and reacted for 10 days under anaerobic conditions;

Abstract

The invention discloses an environment-friendly cultivation substrate specially used for rhododendrons. Its components include: natural retting peat, mushroom mud, rice bran and wheat straw, and cornstarch dregs fermented by yeast and acetic acid bacteria. The above components After adding Bacillus subtilis and crude fiber degrading bacteria to react, then add phytase and perlite. Its preparation method is also disclosed. The invention adopts mushroom mud, rice bran, wheat stalk and cornstarch slag which are convenient and cheap to obtain materials, so as to reduce the cost of special environment-friendly cultivation substrate for rhododendron. Phytase can degrade the phytic acid in the matrix, making the matrix more abundant and easier to absorb nutrients. At the same time, the nutrients in the matrix are in a slow-release state, which can prolong the fertilizer effect. The special environment-friendly cultivation substrate for rhododendrons disclosed by the invention has better water retention and air permeability, can more effectively promote the growth of rhododendron seedlings after being treated with mixed strains, and greatly increase the flowering volume of rhododendrons.

Description

technical field [0001] The invention relates to a special environment-friendly cultivation substrate for rhododendrons and a preparation method thereof, belonging to the technical field of seedling breeding. Background technique [0002] With the development of society and economy, people's pursuit of beauty is increasing day by day. Flowers play a mainstream role in improving people's quality of life and decorating the living environment. With the expansion of flower planting area, the amount of cultivation substrate is increasing rapidly. Rhododendron likes acidic soil, and most urban cultivation soils in my country cannot meet its growth needs, so peat with weakly acidic pH has become the most used substrate in rhododendron cultivation; however, peat, as a non-renewable natural resource, Excessive mining will lead to the destruction of wetland environment. In the new situation of global advocacy of environment-friendly agriculture and forestry in the new century, the use ...
