Embodiment 1

[0025] A kind of preparation method of watermelon plug seedling raising substrate, the steps are as follows:

[0026] 1) The residues of silkworm excrement and stevia straw were stacked and fermented separately in the early stage to obtain decomposed silkworm excrement and stevia residue decomposed clinker with excellent physical, chemical and biological properties;

[0027] 2) Use livestock and poultry manure as earthworm food to provide an environment suitable for the growth of earthworms, and sieve the vermicompost produced by earthworm treatment into 1-4mm particle size vermicompost;

[0028] 3) Prepare expansive vermiculite with a particle size of 1-3mm;

[0029] 4) Fully mix the decomposed silkworm excrement, stevia residue decomposed material, vermicompost, and expansive vermiculite prepared in steps 1), 2), and 3) to make a watermelon plug seedling substrate (ESEV seedling substrate). The volume percentages are: decomposed silkworm excrement 5-15%, stevia residue deco...

Embodiment 2

[0031] A preparation method of a watermelon plug seedling substrate, the steps of which are the same as in Example 1, and the volume percentage of each component mixed to form a watermelon plug seedling substrate (ESEV1) is: decomposed silkworm excrement 10%, stevia residue decomposed clinker 50% %, vermicompost 20%, expansive vermiculite 20%. That is, the proportion of decomposed silkworm excrement-stevia residue decomposed material-vermicompost-expandable vermiculite of the ESEV1 seedling-raising substrate is 1-5-2-2.

Embodiment 3

[0033] A preparation method of a watermelon plug seedling substrate, the steps of which are the same as in Example 1, and the volume percentage of each component mixed to form a watermelon plug seedling substrate (ESEV2) is: decomposed silkworm excrement 10%, stevia residue decomposed clinker 60% %, vermicompost 20%, expansive vermiculite 10%. That is, the proportion of decomposed silkworm excrement-stevia residue decomposed material-vermicompost-expandable vermiculite of the ESEV2 seedling-raising substrate is 1-6-2-1.

Abstract

The invention discloses a plug seedling substrate for watermelons and a preparation method of the plug seedling substrate. The plug seedling substrate for watermelons is prepared by mixing the following components in percentage by volume: 5-15 percent of decayed silkworm excrement, 50-60 percent of decayed stevia rebaudiana residue, 15-30 percent of wormcast and 10-20 percent of expandable vermiculite. The wormcast is wormcast aggregate which can achieve very excellent physical and chemical properties and is obtained by earthworm slaking and conversion of feces of livestock and poultry. The plug seedling substrate is simple in preparation method, rich in resources, low-price in used materials, sufficient in nutrients and stable in property and has the advantages of turning wastes into wealth, reducing the environmental pollution, being used for plug seedling of watermelons, completely or partially dispensing with top application during seedling raising, improving the watermelon quality, reducing the pesticide using amount, ensuring the seedling raising quality, saving manpower and cost and providing reliable guarantee for survival, high-quality efficient growth, yield and quality of transplanted watermelons.

Description

technical field [0001] The invention relates to a preparation raw material and a preparation method of a watermelon plug seedling cultivation substrate, belonging to the technical field of substrate seedling cultivation. Background technique [0002] Substrate seedling cultivation refers to a method of crop seedling cultivation that provides a place for crop seed germination and seedling growth through a substrate in a certain place or container, fixes the root system of the crop and allows it to absorb nutrients and oxygen. According to the development trend of seedling raising methods, matrix seedling raising will become the mainstream seedling raising method. Seedling substrate refers to the growth medium that can provide water, fertilizer, air, heat and other life factors for the stable and coordinated supply of crop seed germination and seedling growth. In addition to supporting and fixing seeds and seedlings, it is more important to act as a carrier of nutrients and wa...
