Embodiment Construction

[0015] 1. Mixed fermentation of plant materials

[0016] 1. Raw material preparation: bagasse and broken stalks are prepared according to the volume ratio of 2-4:1, and urea is prepared according to 1.0-2.5 kg / m3. Among them, corn, sorghum, rice, wheat and other food crops are the best for crushing straw, and reeds, leaves, weeds, etc. can also be used in production. One or more of them can be used alone in production. After crushing, the material is broken into fiber flocs or small fragments with a length of less than 60 mm. Plant materials can be fresh or dry.

[0017] 2. Mixing of materials: bagasse and crushed stalks are mixed according to the volume ratio of 2-4:1, and urea is mixed according to the production amount according to the ratio of 1.0-2.5 kg / m3. The sum of the volume percentage of the plant mixture is 100%.

[0018] Bagasse

[0019] 3. Heap fermentation: the volume of each pile of fermentation materials is not more than 20,000 cubic meters, and ...

Abstract

The process of preparing floating seedling raising medium includes the following steps: 1. crushing plant stalk; 2. mixing with bagasse, urea and water in the C / N ratio of 25-30, and fermenting for 8-12 months to obtain rotted material; 3. high temperature sterilizing; and 4. crushing and mixing the rotted material 30-50 wt%, perlite 20-30 wt%, vermiculite5-15 wt%, and lignite 15-30 wt%, and packing. The floating seedling raising medium has renewable source, stable quality, favorability to seedling growth, low cost and other advantages.

Description

technical field [0001] The invention relates to an artificial seedling-raising substrate and a preparation method thereof, in particular to a floating seedling-raising substrate and a preparation method thereof. technical background [0002] Floating seedling raising is a relatively advanced new seedling raising method at present. Compared with conventional seedling raising, it has the characteristics of saving labor, time, land, cultivating strong seedlings and being convenient for commercial production management. In recent years, floating seedling cultivation technology has been widely used and promoted in the cultivation of crops such as tobacco, vegetables and flowers, and has achieved good economic and social benefits. Substrate is the key material for floating seedlings, the quality of the substrate is directly related to the quantity and quality of seedlings, and the cost of substrate is the main factor restricting the popularization and stable development of floati...
