Problems solved by technology

[0004] The value of plant ash has long been recognized by people. The most used situation is to add it directly to the farmland as a fertilizer. However, due to the scattering of plant ash, it will cause waste and bring environmental pollution when it is used in strong winds.

Embodiment Construction

[0016] A modified corncob cultivation substrate, comprising the following component raw materials in volume ratio: modified corncob 55-65, perlite 10-15, vermiculite powder 10-15, peat 10-15, modified plant ash 5-10,

[0017] Preparation:

[0018] (1) Preparation method of modified corncob: dry, crush and siev the corncob to make particles with a particle size of 5mm, then pour the corncob particles into warm water at 35℃ and soak for 2h, then press The ratio of enzyme activity to corncob weight is 45IU / g. Add acid cellulase, adjust pH to 5.0 with acid, enzymatically hydrolyze at room temperature for 36h; then according to the ratio of enzyme activity to corncob weight to 20IU / g Add acid cellulase and enzymatically hydrolyze at room temperature for 10 hours; increase the temperature to 70~80℃ and keep for 2~3h to inactivate the enzyme to obtain the corncob enzymatic hydrolysis crude solution; filter the corncob enzymatic hydrolysis crude solution and add the weight of the filter r...

Abstract

The present invention provides a modified corn cob cultivation matrix including the following component raw materials: in volume ratio, 55-65 parts of modified corn cob, 10-15 parts of perlite, 10-15 parts of vermiculite powder, 10-15 parts of peat and 5-10 parts of modified plant ash. During preparation, firstly, plant ash and corn cob are modified, and then mixed with other components according to the requirements of the formula. The cultivation matrix of the present invention is reasonable in raw material ratio, is prepared by modifying the plant ash and meanwhile using an enzymic method to modify corn cob fiber, so that the sponginess, air permeability, water retention, heat and moisture retention and nutrient content of the prepared cultivation matrix are improved significantly, the plant ash is modified for granulation, so that the flying property and alkalinity of the plant ash can be effectively improved, the windage loss of the plant ash is reduced, the economic benefits of the utilization of waste products can be realized, the prepared cultivation matrix is suitable for cultivation of various plants, the transplanting survival rate is high, the slow seedling time after transplanting is short, the survival rate is high, and the incidence of diseases and insect pests is low.

Description

technical field [0001] The invention relates to a plant cultivation substrate, in particular to a modified corn cob cultivation substrate and a preparation method thereof. Background technique [0002] The cultivation medium originally originated from the concept of soilless cultivation, which means that the soil environment around the crops has deteriorated, which has seriously affected the yield and quality of the crops. Absorb nutrient solution and oxygen. The so-called cultivation substrate refers to the solid medium that replaces the soil to provide mechanical support and material supply for crops. [0003] Corn cobs are made by crushing corn cobs and then undergoing strict screening. They have the advantages of uniform structure, suitable hardness, good toughness, strong water absorption and good wear resistance, and are not easy to break during use. Since corn cob is rich in cellulose, hemicellulose, lignin, etc., it is difficult to decompose into small molecules an...
