preparation example Construction

[0025] A rice seedling raising substrate and a preparation method thereof, comprising the following steps:

[0026] (1) Raw material preparation: crush rice straw, wheat straw, corn straw and other crop straws with a pulverizer or cut them into 1-3 cm long segments with a hay cutter, and use rice husks, cow dung, cakes, and microbial fermentation aids Prepared, wherein each weight component is: 35%-45% of crop straw, 27%-34% of rice husk, 16%-24% of cow dung, 7%-15% of cake, preferably the weight component is: crop straw 40%, rice husk 30%, cow dung 20%, cake 10%.

[0027] (2) Invasion: measure the water content of crop straw and rice husk, then take the water content of crop straw and rice husk as 50% to 65% as a benchmark, preferably 60% of water content as a benchmark, and add water to the crop straw and rice husk After mixing and soaking, pile up and place for more than 24 hours.

[0028] (3) Straw building: fully mix the microbial fermentation aid with cow dung and cake...

Abstract

The invention relates to the technical field of seedling matrixes of crops and particularly relates to a rice seedling matrix and a preparation method thereof. The rice seedling matrix with good permeability and high fertility is particularly prepared from the main raw materials of crop straws, cow mature, rice husk, seed cakes, microbial zymophyte and the like through steps of material preparation, soaking, straw piling, straw composting, matrix preparation and the like. The rice seedling matrix comprises the following main raw materials in percentage by weight: 35%-45% of the crop straws, 27%-34% of the rice husk, 16%-24% of the cow mature and 7%-15% of seed cakes, wherein 1kg of the microbial zymophyte is used in each 5-6 cubic meters of the crop straws. According to the preparation method, the soil-free matrix production is realized, the utilization of non-renewable resources is reduced, the damage caused to farmland soil resources is reduced, the environment is protected, the factory seedling is realized, the cost is lowered, the plant diseases and the insect pests are reduced, the content of soil organic matters is increased, and the yield and the milled rice rate can be increased.

Description

technical field [0001] The invention relates to a rice seedling raising substrate and a preparation method thereof, belonging to the technical field of crop seedling raising substrates. technical background [0002] In traditional seedling raising, fertile plow layer soil is used as the seedling bed soil. To plant 1 mu of rice, 150 kg of seedling bed soil is required every year. The selection of plow layer soil also causes damage to farmland soil resources. [0003] At present, a lot of research on rice seedling raising using substrates instead of nutrient soils has been carried out in China. The rice seedling raising substrates are basically peat, vermiculite, and perlite mixed with nitrogen, phosphorus, potassium, trace elements, and bactericidal and insecticides. As a common raw material for seedling cultivation, peat has been formed for thousands of years and is a non-renewable resource. There are also some studies that use renewable resources such as straw and human an...
