Embodiment 1

[0035] Embodiment 1: On the basis of the intermittent irrigation methods disclosed in the above-mentioned embodiments, the intermittent irrigation in this embodiment is mainly the irrigation in the transplanting and greening stages, that is, keeping a shallow water layer less than 3 cm; The shallow water layer is suitable; after transplanting the seedlings, it needs to be filled with about 30mm of greening water, and keep it until the greening ends.

Embodiment 2

[0036] Embodiment 2: On the basis of the intermittent irrigation methods disclosed in the above-mentioned embodiments, the intermittent irrigation of the present embodiment mainly includes the irrigation in the early stage of tillering, that is, for early rice, the shallow water layer with a depth of 20mm is irrigated, and it naturally dries to the soil. Irrigate again when the water content reaches a saturation rate of 70% to 90%. For late rice, irrigate a shallow water layer 30mm deep, and let it dry naturally until the soil water content reaches a saturation rate of 70% to 90%.

Embodiment 3

[0037] Embodiment 3: On the basis of the intermittent irrigation methods disclosed in the above embodiments, the intermittent irrigation of this embodiment also includes irrigation from the early tillering period to the late tillering period: in this period, the field needs to be baked, and according to the condition of the seedlings, the water should be dried until the saturated moisture content is reached. 70%~80%, take the lower limit for those with good seedling condition, otherwise take the upper limit; the irrigation from the early tillering period to the late tillering period includes intensity intermittent irrigation and mild intermittent irrigation; the intensity intermittent irrigation is aimed at the high soil fertility, An irrigation method with strong reducing ability and vigorous seedling growth, the mild intermittent irrigation is an irrigation method aimed at alluvial clay loam soil with medium to high fertility and normal growth of rice seedlings.

Abstract

The invention discloses a rice field methane emission reduction method and a microbial additional fertilizer for methane emission reduction. The method comprises the steps of seed soaking, sowing and seedling raising in a rice seedling bed period; performing rice field water covering and fertilization treatment; seedling transplanting, wherein the cultivated seedlings are transplanted in a wide-row narrow-distance mode; and adopting irrigation treatment, wherein an intermittent irrigation mode for treatment. According to the intermittent irrigation mode, the rice field is irrigated in the mode that every time the rice field is irrigated with water, after the field surface is naturally dried to be in a water-free layer state, the rice field is irrigated with water again. According to the method, the rice field is irrigated in a special intermittent irrigation mode, the income and yield of rice are increased, and the technology can be applied to large-scale rice planting.

Description

technical field [0001] The present application relates to the field of microorganisms, in particular to a method for reducing methane emissions in paddy fields and microbial additional fertilizers for reducing methane emissions. Background technique [0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. The scope of application of fermentation engineering includes: ⑴ pharmaceutical industry, ⑵ food industry, ⑶ energy industry, ⑷ chemical industry, ⑸ agriculture: transformation of plant genes; biological nitrogen fixation; engineering insecticide biopesticides; microbial feed. ⑹Environmental protection, etc. [0003] Rice fields are one of the important emission sources of atmospheric methane, and m...
