Rice seedling raising matrix with soil conditioning function

Abstract

The invention discloses a rice seedling raising matrix with a soil conditioning function. The rice seedling raising matrix comprises urea resin foam particles and kitchen waste particles, and the kitchen waste particles are bonded on the surfaces of the urea resin foam particles. According to the rice seedling raising matrix with the soil conditioning function, urea resin foam is in the shape of particles, a large number of holes exist among the urea resin foam particles except holes in the urea resin foam particles, therefore, water holding, ventilating, rooting and germinating are facilitated, and meanwhile the using amount of the urea resin foam is reduced and usage of perlite and vermiculite is completely eradicated; kitchen waste is used to replace grass carbon, therefore, the problem of grass carbon resource depletion is solved, waste materials are changed into things of value, the kitchen waste is fully used, and the kitchen waste treatment problem is solved; meanwhile, the kitchen waste is subacid after being fermented, the soil alkalinity can be neutralized, the soil conditioning function is achieved, therefore, neutralized soil is not hardened any more, the volume weight is decreased, the holes are increased, and crop germinating and growing are facilitated.

Description

Technical field: [0001] The invention relates to the technical field of seedling-raising substrates, in particular to a rice seedling-raising substrate with soil conditioning function. Background technique: [0002] Soilless culture refers to a cultivation method that does not use natural soil but uses a substrate or only uses a substrate when raising seedlings, and irrigates with nutrient solution after planting, which can save land. Because soilless culture can artificially create a good rhizosphere environment, It can effectively prevent the physiological obstacles caused by continuous soil diseases and soil salt accumulation, and fully meet the needs of crops for environmental conditions such as mineral nutrition, water, and gas. Workmanship, high yield and high quality. [0003] After the nationwide snow disaster in 2010, factory-based seedlings were gradually accepted by many people of insight in agriculture, which greatly promoted the research on the application of s...

[0008] In addition, in many areas, especially in the Northeast, the soil has a large volume, compaction, and airtightness, which is not conducive to the emergence and growth of crops. Soil conditioners need to be added to improve
