Problems solved by technology

However, nitrogen loss is common during the composting process, most of which are ammonia (NH 3 ) into the atmosphere in the form of volatilization, which not only pollutes the environment and threatens human health, but also reduces the nutrient content in fertilizers

Embodiment 1

[0025] This example provides a kind of preparation method of organic greening spraying base material, and its specific steps are as follows:

[0026] 28kg of corn stalks with a moisture content of 25wt% were pulverized, passed through a 40-mesh sieve, and then mixed evenly with 30kg of peat with a moisture content of 25wt% and 10kg of dried rice husk. In this embodiment, the peat In the dry basis, the weight of the dry basis is 100%, containing 30-70 wt% humic acid. The use of the peat is beneficial to increase the nutrient content in the prepared base material. The mixed materials are stacked in the form of triangular strips for open-air composting. According to the measurement results of C and N content in the raw material, adjust the moisture content of the mixed material at 60-65wt%, and the carbon-nitrogen ratio at 27:1-30:1. During the entire fermentation process, the indoor temperature is controlled at 15-20°C, and the materials are turned and thrown once a day. By tu...

Embodiment 2

[0030] This example provides a kind of preparation method of organic spraying base material, concrete steps are as follows:

[0031] 40kg of corn stalks with a moisture content of 30wt% were pulverized, passed through a 60-mesh sieve, and mixed evenly with 40kg of peat with a moisture content of 20wt% and 16kg of dried rice husk. The mixed materials are stacked into triangular stacks for open-air composting and fermentation. According to the measurement results of C and N content in the raw materials, the water content of the mixed materials is adjusted to 55-60wt%, and the carbon-nitrogen ratio is 25:1-26: 1. During the fermentation process, the indoor temperature is controlled at 20~25°C, and the material is turned over once a day. During the first turning over, 1.6kg of n-butylthiophosphoric triamide is added to the material And mix evenly. When the fermentation is about 20 days, use a sieving machine to sieve, sieve out the materials that are not completely decomposed and...

Abstract

The invention provides an organic spray-seeding greening base. The base comprises, by weight, 50-60 parts of clay, 10-25 parts of rice husk, 6-10 parts of straw, 1-3 parts of a urease inhibitor and 5-10 parts of peat. The invention provides a preparation method of the organic spray-seeding greening base. The organic spray-seeding greening base has the advantages of high production efficiency, good environment safety, relative stability of a soil granule structure, stability of a fertilizer conservation and water retention structure and smooth spray-seeding effects and satisfies waste resourcing, scale expansion and industrialization development tendency and spray-seeding greening requirements.

Description

technical field [0001] The invention relates to the field of substrates for greening, in particular to an organic spray-seeded greening substrate and a preparation method thereof. Background technique [0002] Spray seeding greening is a new greening technology that originated in the late 1980s in the restoration of the waste mine of the Ashio Copper Mine in Tochigi Prefecture, Japan. It is to fully mix the grass seed fertilizer, water retaining agent, soil, organic matter, stabilizer and other mixtures, and then spray it evenly to the slope of the project to be protected according to the designed thickness through the jet machine, so as to achieve the purpose of landscape similar to natural greening. At the spraying site, the spraying substrate is basically in a random state due to the lack of uniform standards, which seriously affects the spraying speed and the quality of greening; Incineration pollution of shells and straws has become a prominent problem of environmental...
