Problems solved by technology

[0003] Bamboo has the advantages of fast growth, high yield, strong regeneration ability, etc. Bamboo resources are renewable green materials, but the direct use of bamboo raw materials such as bamboo chips, bamboo particles, etc. as plant culture substrates has the following unfavorable factors, water absorption It is not suitable as a substrate for plant cultivation because of its poor water-holding capacity, slow nutrient release, and low microbial activity. Therefore, it is of scientific significance and very important to use bamboo resources as raw materials to produce plant cultivation substrates. Practical significance

Embodiment 1

[0028] A plant culture substrate produced by utilizing bamboo chips is prepared by the following method:

[0029] (1) Crushing of raw materials: Use a roller crusher to crush the bamboo chips into small loose bamboo particles with a length less than 2 cm and a diameter less than 0.4 cm.

[0030] (2) Ammonification treatment: put the small bamboo particles obtained in step (1) into an ammoniation container for ammoniation, and add urea solution (the amount of nitrogen in the urea solution is The mass concentration is 5%), and then adjust the water content of the mixed raw materials to 35%. After mixing evenly, seal the ammoniation container for ammoniation. The ammoniation time is: when the ambient temperature is above 20°C, the ammoniation time is 7 days , when the ambient temperature is lower than 20°C, the ammoniation time is 14 days.

[0031] (3) Fermentation: 80 parts by weight of the ammonified bamboo particles in step (2), 10 parts by weight of biochar and 0.2 parts by ...

Embodiment 2

[0033] A plant culture substrate produced by utilizing bamboo chips is prepared by the following method:

[0034] (1) Crushing of raw materials: Use a roller crusher to crush the bamboo chips into small loose bamboo particles with a length less than 2 cm and a diameter less than 0.4 cm.

[0035] (2) Ammonification treatment: the small bamboo particles obtained in step (1) are put into an ammoniation container for ammoniation, and ammonium bicarbonate solution (ammonia bicarbonate The mass concentration of nitrogen in the solution is 12%), then adjust the water content of the mixed raw materials to 50%, after mixing evenly, seal the ammoniation container for ammoniation, and the ammoniation time is: when the ambient temperature is above 20°C, the ammoniation The time is 10 days, and when the ambient temperature is lower than 20°C, the ammoniation time is 30 days.

[0036] (3) Fermentation: 90 parts by weight of the ammonified bamboo particles in step (2), 20 parts by weight of...

Embodiment 3

[0038] A plant culture substrate produced by utilizing bamboo chips is prepared by the following method:

[0039] (1) Crushing of raw materials: Use a roller crusher to crush the bamboo chips into small loose bamboo particles with a length less than 2 cm and a diameter less than 0.4 cm.

[0040] (2) Ammonification treatment: the small bamboo particles obtained in step (1) are put into an ammoniation container for ammoniation, and ammonia solution is added in an amount of N that accounts for 1% of the dry weight of the bamboo particles (the amount of nitrogen in the ammonia solution The mass concentration is 10%), and then adjust the water content of the mixed raw materials to 40%. After mixing evenly, seal the ammoniation container for ammoniation. The ammoniation time is: when the ambient temperature is above 20°C, the ammoniation time is 8 days , when the ambient temperature is lower than 20°C, the ammoniation time is 18 days.

Abstract

The invention discloses a plant culture medium produced by using bamboo sawdust. The plant culture medium is produced by the steps of: crushing a bamboo sawdust raw material into small loose bamboo particles by adopting a rolling type pulverizer, and carrying out ammoniation treatment and a mixed fermentation process with charcoal to prepare the bamboo sawdust into an organic material which has a reasonable pore structure, is good in water retention capacity and reasonable in C / N ratio, and has a volume weight of 0.2-0.5g / cm<3> and a pH value of 6-7. The organic material is suitable for serving as a substrate for garden greening, seedling cultivation and transplantation, and can also be used for soil acidification and physical structure improvement.

Description

technical field [0001] The invention relates to a plant culture substrate, in particular to a plant culture substrate produced by using bamboo chips. Background technique [0002] Substrate cultivation is a cultivation method that can fix the root system of plants in a specific container and absorb nutrients, water and oxygen from it, also known as soilless cultivation. Since the early 1980s, my country's soilless cultivation has developed from agricultural products to many fields such as seedlings, garden flowers, medicinal materials, etc., and has played the role of increasing product output, improving product quality and purifying the cultivation environment. One of the most important aspects of agriculture. The cultivation medium is the basis of soilless cultivation. In addition to the role of fixation, it also provides the plants with the necessary water, fertilizer, air and heat for the plant roots to absorb and utilize. Peat is one of the traditional cultivation subs...
