Crop straw based culture medium and making method thereof

Abstract

The invention provides a crop straw based culture medium and a making method thereof. The crop straw based culture medium comprises the following steps that 1, the crop straw moisture is adjusted, beneficial mixed bacteria are added to crop straws, and uniform stirring is performed; 2, material piling is performed, and the material is covered with a black plastic film after piling to perform anaerobic fermentation; 3, the plastic film is uncovered, compound bacteria are scattered, and pile turnover is performed to begin to perform aerobic fermentation; 4, during the aerobic fermentation, super absorbent resin and rare earth nitrate are added, and even stirring is performed to break the material, namely the crop straw based culture medium is obtained. The crop straw based culture medium contains the beneficial bacteria, can maintain soil fertility, effectively restrains root diseases, effectively promotes crop growth, contains the super absorbent resin, improves the water-retention rate and fertilizer-retention rate of soil and is added with the rare earth nitrate to promote crop growth, nitrogen, phosphorus, potassium, calcium, magnesium, organic matter and the like of the crop straws are utilized fully, waste is turned into wealth, and the cost of the medium is reduced.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a cultivation substrate based on crop stalks and a preparation method thereof. Background technique [0002] Cultivation substrate refers to the solid medium that replaces soil to provide mechanical support and material supply for crops. At present, people hope that the cultivation conditions will be better or more convenient. For example, when growing vegetables on the balcony, they will choose the cultivation substrate with large water retention and light weight. Therefore, the cultivation substrate is more and more favored by people. [0003] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich...

AI Technical Summary

Problems solved by technology

However, most of the crop straws are now burned, which has caused great damage to the environment. Therefore, it is of great significance to develop the comprehensive utilization of crop straws

[0004] Most of the current organic matrix comes from underground excavation, which is a non-renewable resource, which causes a waste of resources

There is also a part of the substrate, which comes from the reprocessing of waste, such as coconut shells, mushroom residues, and reed foam from paper mills. The fertility of this part of the substrate is relatively low, and the water retention capacity is relatively poor, which cannot meet the needs of plant growth.
