Method utilizing industrial waste to prepare rice seedling raising soil for rice seedlings growing in trays made of plants

Abstract

The invention relates to a method utilizing industrial waste to prepare rice seedling raising soil for rice seedlings growing in trays made of plants. The method specifically includes the following steps: (1) selecting farmland soil samples, as references, needed for preparing the rice seedling raising soil; (2) preferably selecting varieties of the industrial waste which can be used for preparing the rice seedling raising soil; (3) obtaining a rice seedling raising soil preparing method which is applicable to rice raising in the trays and takes the industrial waste as a main material; (4) controlling an optimum formula of the rice seedling raising soil from the mechanisms; (5) checking biological toxic properties of rice seeds cultivated by the rice seedling raising soil; (6) performing pilot test on the rice seedling raising soil and perfecting the formula of the rice seedling raising soil. The technology has broad potential application value and is not limited to rice seedling raising in the trays made of the plants, application range of the method covers all soils for rice seedling raising. By the method, the industrial waste can be recycled, occupancy and damage to farmland soil can be reduced, recycling of resources is realized, and sustainable development is benefitted.

Description

technical field [0001] The invention relates to a method for preparing rice seedling-raising soil in pots with plant matter by utilizing industrial waste, and belongs to the technical field of industrial waste treatment. Background technique [0002] Rice is the grain crop with the largest planting area, the highest yield per unit area, and the largest total yield in China. Rice production occupies an extremely important position in my country's grain production. The annual planting area of ​​rice is about 30 million hectares, accounting for 30% of the country's grain planting area and 20% of the world's rice planting area; the total rice output is nearly 200 million tons, accounting for 40% of the country's total grain output and 20% of the world's total rice production 35%. The healthy, stable and sustainable development of the rice industry plays a decisive role in ensuring the development of the national economy and food security in our country.
