Abstract

The invention provides a method for cultivating oats by using mixed soil of domestic sludge and aeolian sandy soil and belongs to the technical field of agricultural production. The method comprises the following steps: (1) selecting a paper cup, and forming a circle of small holes in the paper cup so that water can enter the mixed soil through the small holes; (2) mixing domestic sludge and aeolian sandy soil, grinding, and sieving with a sieve for later use to obtain mixed soil; (3) sterilizing; (4) selecting full seeds with the same size, soaking the seeds in a rooting solution overnight, washing the seeds with sterile water, and airing the seeds for later use; (5) sowing; (6) placing the seeds in an artificial climate incubator to cultivate robust oat seedlings; (7) performing field management: planting the seedlings in a field, weeding between a tillering stage and a jointing stage, and harvesting oat grass. According to the method, the domestic sludge and the aeolian sandy soil which is difficult to use are improved and utilized, the cultivated oats are fast and neat in seedling emergence, and a feasible, convenient and fast planting method is provided for oat cultivation.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for cultivating oats with mixed soil of domestic sludge and aeolian soil. Background technique: [0002] Domestic sludge is a solid deposit produced in the process of urban domestic sewage treatment. It has a huge amount and grows rapidly. Arbitrary throwing and stacking will cause secondary pollution, which will bring about more serious urban ecological environmental problems. Sludge contains a large amount of organic matter and nutrients, which can be used in ecological management fields such as soil improvement and desertification control after harmless treatment. At present, due to various reasons such as heavy metals, pathogenic bacteria, and organic pollutants, it is difficult to widely promote the utilization of resources such as fertilization and agriculture, and the main disposal methods are incineration, landfill, and ocean discharg...
