Problems solved by technology

Dense water hyacinth reduces the penetration of light into the water body, affects the growth of underwater organisms, increases the concentration of carbon dioxide in the water, and reduces the yield of aquatic products
Water hyacinth will also age and rot. If it is not salvaged in time, the harmful substances such as phosphorus adsorbed by it will decompose again and sneak into the water

Embodiment 1

[0021] Production of organic substrates using water hyacinth.

[0022] According to the above method: the freshly salvaged water hyacinth is pulverized by a pulverizer, squeezed by a juicer, separated from solid and liquid by a filter, and fermented with solid slag to obtain an organic substrate.

[0023] The produced organic substrate was used for soilless cultivation of eggplant, and the control substrate was 100% perlite. The yields were as follows: 3,149 kg of cucumbers grown on organic substrates and 2,950 kg of cucumbers grown on perlite, an increase of 6.7%.

Embodiment 2

[0025] Production of organic substrates from tomato leaves.

[0026] According to the above method: crush the freshly crushed tomato leaves through a pulverizer, squeeze with a juicer, separate the solid and liquid with a filter, and ferment the solid residue to obtain an organic substrate, and then mix the substrate with the fermented mushroom residue at a ratio of 1:1 The volume ratio is mixed to obtain an organic composite matrix.

[0027] The produced organic composite matrix was used for soilless cultivation of eggplant, and the control matrix was 100% perlite. The yields were as follows: 3,415 kg of cucumbers grown on organic substrates and 2,950 kg of cucumbers grown on perlite, an increase of 15.8%.

Abstract

A process for preparing organic matrix of fertilizer from the water hyacinth and the stem and leaf of agricultural crops includes breaking, squeezing, solid-liquid separation to obtain solid, natural fermenting or adding EM or CM bacteria for microbial fermenting to obtain organic matrix, and mixing with fermented mushroom dregs or peat to obtain composite organic matrix. Its advantages are high fertilizer and water preservation.

Description

1. Technical field: [0001] The invention relates to an organic fertilizer, and in particular discloses a process for producing an organic substrate by using water hyacinth and crop stems and leaves. The invention is mainly used for soilless cultivation of vegetables, fruits, flowers and seedlings, and belongs to the field of modern agriculture. 2. Background technology: [0002] As an important technology for high-quality and high-yield vegetables, soilless cultivation has developed very fast in developed countries in the world, especially in Europe. In 1995, the soilless cultivation area in the Netherlands was 5110 hectares, accounting for 51% of the total greenhouse area; the soilless cultivation area in Turkey was 1030 hectares, accounting for 46% of the total greenhouse area; the soilless cultivation area in France was 983 hectares, accounting for 51% of the total greenhouse area. 36% of the total; Japan's soilless cultivation area is 760 hectares, accounting for 1-2% of...
