Method for preparing flower substrate from agricultural wastes

Abstract

The invention discloses a method for preparing a flower substrate from agricultural wastes, and particularly relates to straws and livestock / poultry manure agricultural wastes. The method comprises the following steps: mixing a corn flour extracting solution and beneficial microorganisms to obtain a fermentation liquid microbial inoculant, uniformly mixing the liquid microbial inoculant with straws, livestock / poultry manure and corn flour, fermenting for 20-30 days, and proportionally mixing the obtained organic fertilizer with perlite, vermiculite, peat and a water retention agent to obtain the flower culture substrate. The substrate has light volume weight, and thus, is convenient to transport. The substrate has favorable water retention property, thereby reducing the watering frequency and saving the water consumption. The substrate has abundant nutrient substances, and does not need any additional chemical fertilizer in the flower growth period. The substrate lowers the flower planting cost and disease / pest possibility. The substrate solves the problem of environment pollution caused by improper treatment of agricultural wastes.

Description

Technical field [0001] The invention belongs to the field of flower cultivation and agricultural waste utilization, and particularly relates to a method for preparing flower substrates from straw and livestock manure. Background technique [0002] At present, in flower cultivation, the development of soilless substrate is more and more popular. Because peat contains a lot of organic matter, it has good air and water permeability, good water retention performance, small bulk density, light texture, and no pests and eggs. It is often used as a flower Cultivation substrate. However, my country's extensive mining of peat substrates has resulted in low added value of products, single nutrition, poor water retention, difficult rooting, low germination rate, and high nursery mortality, which cannot meet the needs of large-scale growth of flowers in agriculture, forestry, horticulture, and increased flower production. the cost of. Therefore, finding an alternative material for peat subs...

Zhang Qiang, Luan Yaning, and Gong Xiaoqiang also improved the decomposed products of agricultural, forestry and garden wastes to prepare flower substrates. However, because straw wastes contain a large amount of cellulose that is difficult to degrade and hemicellulose, resulting in a long period of decomposition and low nutrient content of the fermented product, which is difficult to meet the needs of long-term growth of flowers
