Problems solved by technology

[0002] Rice is one of the most important food crops in my country. Its sowing area accounts for about 1 / 4 of the total area of ​​food crops. In production, a large amount of rice straw is produced every year, some of which are used for returning to the field, and most of them are burned, which seriously pollutes the environment. , but also cause waste of resources
At present, there are still many problems in the direct use of rice straw to make seedling raising substrates

Embodiment 1

[0018] A carbon-based seedling-raising substrate for rice, comprising the following components in percentage content: 10% of cake fertilizer, 0.2% of inorganic compound fertilizer, 5% of diatom mud, 5% of tailings, and the balance of biochar. The biochar is made of rice husk, Rice straw, sugarcane straw, and bean pod shells are used as raw materials. The preparation method of the biochar is as follows: firstly expose the rice straw and sugarcane straw to the sun for 5-7 days, and then freeze and crush them together until the particle size is 2-3mm, and set aside; chop the bean pod shells and mix them with Soak rice husks with water for 2-3 hours, remove and drain, and then stack them for 2-3 days at a temperature of 20-25°C and a humidity greater than 75%, during which time lime water is sprayed and turned once every 10 hours, and then dried at a constant temperature of 60°C , crushed to a particle size of 2-3mm; blend the crushed materials of rice straw, sugarcane straw, rice ...

Embodiment 2

[0023] A carbon-based seedling-raising substrate for rice, comprising the following components in percentage content: 8% cake fertilizer, 0.5% inorganic compound fertilizer, 10% diatom mud, 8% tailings, and the balance of biochar. The biochar is made of rice husk, Rice straw, sugarcane straw, and bean pod shells are used as raw materials. The preparation method of the biochar is as follows: firstly expose the rice straw and sugarcane straw to the sun for 5-7 days, and then freeze and crush them together until the particle size is 2-3mm, and set aside; chop the bean pod shells and mix them with Soak rice husks with water for 2-3 hours, remove and drain, and then stack them for 2-3 days at a temperature of 20-25°C and a humidity greater than 75%, during which time lime water is sprayed and turned once every 10 hours, and then dried at a constant temperature of 60°C , crushed to a particle size of 2-3mm; blend the crushed materials of rice straw, sugarcane straw, rice husk, and be...

Embodiment 3

[0028] A paddy charcoal-based seedling-raising substrate, comprising the following percentage components: 5% cake fertilizer, 1% inorganic compound fertilizer, 15% diatom mud, 8% tailings, and the balance of biochar. The biochar is made of rice husk, Rice straw, sugarcane straw, and bean pod shells are used as raw materials. The preparation method of the biochar is as follows: firstly expose the rice straw and sugarcane straw to the sun for 5-7 days, and then freeze and crush them together until the particle size is 2-3mm, and set aside; chop the bean pod shells and mix them with Soak rice husks with water for 2-3 hours, remove and drain, and then stack them for 2-3 days at a temperature of 20-25°C and a humidity greater than 75%, during which time lime water is sprayed and turned once every 10 hours, and then dried at a constant temperature of 60°C , crushed to a particle size of 2-3mm; blend the crushed materials of rice straw, sugarcane straw, rice husk, and bean pod shell, ...

Abstract

The invention provides a rice carbon-based seedling-raising substrate and a preparation method thereof. The substrate comprises the following components in percentages: 5-12% of a cake fertilizer, 0.2-1% of an inorganic compound fertilizer, 5-15% of diatom mud, 5-8% of tailings, and the balance of biochar, wherein the biochar is prepared by adopting rice hulls, straw, sugarcane stalks and soybeanhulls as raw materials. According to the method provided by the invention, through a rational raw material ratio and process improvement, the water retention and permeability of the seedling raising substrate are effectively improved, the nutrient content is high, the absorbability is good, the dry matter accumulation is strong, a survival rate and growth rate of seedlings are greatly improved, the seedlings are robust and tidy and have good root twisting performance, and the comprehensive cultivation quality is high.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a rice charcoal-based seedling raising substrate and a preparation method. Background technique [0002] Rice is one of the most important food crops in my country. Its sowing area accounts for about 1 / 4 of the total area of ​​food crops. In production, a large amount of rice straw is produced every year, some of which are used for returning to the field, and most of them are burned, which seriously pollutes the environment. , but also cause a waste of resources. At present, there are still many problems in making seedling-raising substrates directly from rice stalks. [0003] The traditional rice seedling raising substrate is generally made of peat, mixed with perlite and vermiculite, etc., and processed by mixing. Peat is a non-renewable resource, and its price is increasing year by year. The state is also strengthening the supervision of peat mining. Biochar is a new type of soi...
