Rice substrate made from beet pulp and biomass charcoal

Abstract

The invention relates to the field of soilless culture, and discloses a rice substrate made from beet pulp and biomass charcoal. The ice substrate comprises a fermented product from the beet pulp, thebiomass charcoal and vermiculite at a volume ratio of (5-6):1:(2-3), and further includes wood vinegar liquor which accounts for 0.8-1.5% of the total mass of the fermented product from the beet pulp, the biomass charcoal and the vermiculite. Through the rice substrate, the problem that the undernutrition and slow growth of rice seedlings can be caused by destroying, which is resulted from high-temperature sterilization, of nutrients in seedling culturing or planting substrates in the prior art is solved, the raw materials of the rice substrate are easy to acquire and low in price, and the pollution to the environment can be reduced; meanwhile, the height, stem base width and the root quantity of the seedlings can be remarkably improved, so that the development of the seedlings is promoted.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a rice substrate using sugar beet pulp and biochar as raw materials. Background technique [0002] Rice occupies an extremely important position in my country's grain planting system, and its planting area and total output account for 38% and 45% of the three major food crops (rice, wheat, and corn), respectively. In recent years, with the progress of science and technology and technological innovation, rice mechanized seedling raising technology has been widely used under the joint efforts of the national agricultural department and local technology extension stations. [0003] Assembly line hard disk seedling seeding is the core technology of rice seedling mechanization. The conventional seedling raising method of machine-transplanted rice is to use mature topsoil as seedling bed soil for cultivation. The bed soil consumes a lot. Generally, seedlings need 100kg of bed soil p...

AI Technical Summary

Problems solved by technology

[0006] The production of seedling substrates is generally sterilized by high temperature, but the nutrients in the substrate will be destroyed under the action of high temperature, especially some probiotics, which will have a certain impact on the growth of seedlings

In addition, high-temperature sterilization consumes a lot of energy, and yellow-red soil is a non-renewable resource and is subject to geographical restrictions, which increases the cost of preparing the matrix
