Problems solved by technology

However, nutrient soil releases nutrients quickly, and excessive nutrient content inhibits the growth of the seedling root system, resulting in a significantly smaller root length and root compaction force than those raised in natural soil, and the use of nutrient soil for seedling cultivation has a large amount of soil, difficulty in obtaining soil, and prone to soil transmission. Diseases and herbicide residues affect seedling emergence, large nutrient soil capacity, high transportation costs, and increased mechanical workload. At the same time, it seriously damages the soil resources of my cou

preparation example Construction

[0025] A method for preparing a rice seedling-raising substrate produced from plant stalks and beer activated sludge, comprising the following steps:

[0026] Step 1: High-temperature aerobic fermentation, the plant straw is crushed into 5-10mm segments, and 50%-70% of the plant straw is mixed with 30%-50% of beer activated sludge by volume percentage, so that the initial Moisture is controlled at 50%-55%; 0.5%-1.5% straw decomposing agent and 1.5%-2.5% nitrogen fixer are added to the obtained mixture according to the mass ratio through a computer metering belt scale, and then carried out in a solar composting rapid heating device High-temperature aerobic fermentation, turning the heap 4-5 times, after 20-22 days, transfer to the aging workshop for secondary fermentation and decomposing;

[0027] Step 2: Secondary aerobic fermentation, adding cellulolytic bacteria to the organic material fermented in the first stage, using intermittent oxygen supply in the aging workshop, aero...

specific Embodiment

[0069] The test substrate is the rice seedling raising substrate produced by plant straw and beer activated sludge of the present invention. The nutrient, water and carbon-nitrogen ratio of compost materials are very important to the influence of compost fermentation. The suitable carbon-nitrogen ratio for microbial decomposition of organic materials is 25 The normal fermentation time is about 25 days. The raw materials selected in the test were averaged after several tests of their physical and chemical properties, and the results showed that the carbon-nitrogen ratio of crop straw was high, about 40 to 60 (Table 1); beer activated sludge refers to fermentation wastewater The activated sludge precipitated after treatment is mainly composed of waste yeast sludge that cannot be reused after several generations of fermentation. It contains 29.97% crude protein and its heavy metals are lower than the national standard (Table 2). The traditional treatment method is landfill Or sur...

Abstract

The invention relates to the technical field of agricultural substrate production, and provides a rice seedling raising substrate produced from plant straws and beer active sludge and a preparation method thereof. The rice seedling raising substrate is prepared from 50%-70% of plant straws and 30%-50% of beer sludge through mixing and high-temperature aerobic fermentation, secondary fermentation and thorough decomposition, addition of an inorganic material into thoroughly decomposed organic materials, and acid regulating agent preparation in sequence. The substrate preparation method is shortin fermentation time, and maturity of the straws is high. An acid regulating technology ensures that the pH value of the rice seedling raising substrate is stable, so that the rice seedling raising substrate is suitable for rice seedling growth, is good in water retention and fertilizer retention, is comprehensive in nutrition, can meet nutrition needs of growing rice seedlings for 40 days, and greatly reduces load of a rice transplanter. The rice seedling raising substrate solves the problems that soil take of mechanical rice transplanting is difficult, land resources are wasted, environmental pollution is caused by direct discarding or combustion of waste biomass, and the like; and meanwhile, development and use of the rice seedling raising substrate are beneficial for promoting sustainable production of high-efficiency agriculture, so that rural income is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural matrix production, in particular to a rice seedling-raising matrix produced from plant straw and beer activated sludge and a preparation method thereof. Background technique [0002] In recent years, with the expansion of rice planting area and the popularization of machine-transplanted dry seedling raising technology, the rice seedling raising substrate is particularly important. At present, the rice transplanter is matched with the standard hard disk seedling raising. In most areas, the soil is taken from the plow layer soil of the farmland, dried and crushed, and then added with nutrients and seedling raising agents to prepare nutritious soil, and then packed into trays and sowed to raise seedlings. However, nutrient soil releases nutrients quickly, and excessive nutrient content inhibits the growth of the seedling root system, resulting in a significantly smaller root length and root comp...
