Problems solved by technology

[0003] Many departments in our country have conducted research on alien invasive plants. The main methods used to control invasive plants are manual extraction and chemical control. Manual extraction alone requires an investment of 100 million yuan per year, and chemical control has an impact on the ecological environment. no effective control system

Embodiment 1

[0024] Example 1. Preparation of seedling substrate block made of alien invasive plants

[0025] Specific preparation process:

[0026] 1) Adding the main ingredient made from the stems of invasive alien plants: screening and testing the stems of invasive alien plants, composting and fermentation, then crushing and sorting the stems of invasive alien plants for reasonable particle grading (1~ 3mm particle gradation accounted for 45% to 55%), remove excessive ash and large blocks, make the size of the material uniform, the physical and chemical properties are uniform, and then dry to a water content of 3 , Water holding capacity> 400%, 1~3mm particle size gradation> 50%, roundworm egg mortality ≥ 95%, coliform value ≤ 1 / 10, oxidation-reduction potential value (Eh) 200-600mV. The invasive alien plants are Eupatorium adenophorum, Fumaria, Mikania, Plantaria, Guayule, Tribulus sibiricum or Solanum eryngii, which account for 20% of the total main ingredients.

[0027] 2) The main materia...

Embodiment 2

[0034] Example 2. Preparation of seedling substrate block made of invasive alien plants as raw materials

[0035] The invasive alien plants Eupatorium adenophorum, yellow-head chrysanthemum, Mikania micrantha, airplane grass, guayule, Tribulus terrestris or Eryngium solanum stems account for 50% of the total amount of the main ingredients, and the mud (grass) charcoal accounts for the total amount of the main ingredients. 50%; other preparation steps are the same as in Example 1.

Embodiment 3

[0036] Example 3. Preparation of seedling substrate block made of alien invasive plants as raw materials

[0037] The invasive alien plants Eupatorium adenophorum, yellow-head chrysanthemum, Mikania micrantha, airplane grass, guayule, Tribulus terrestris or Eryngium solanum stems account for 35% of the total amount of the main ingredients, and the mud (grass) charcoal accounts for the total amount of the main ingredients. 65%; other preparation steps are the same as in Example 1.

Abstract

The invention relates to a seedling culturing substrate block and a preparation method thereof. The seedling culturing substrate block provided by the invention comprises Eupatorium adenophorum as a major ingredient. The major ingredient of the seedling culturing substrate block provided by the invention comprises one or more of Flaveria bidentis, Mikania micrantha, Eupatorium odoratum, guayule, Cenchrus Paciflorus and Solanum rostratum, and the content of the major ingredient is 20-50 wt%; the major ingredient comprises peat or vermiculite, and has the content of 50-80 wt%; and the auxiliarymaterial comprises a nutrient ingredient and a regulator, and has the content of 1-2 wt%. By using the seedling culturing substrate block provided by the invention, nutrients needed by plant growth and contained in a conventional seedling culturing substrate can be provided; meanwhile, roots of seedlings can be promoted to grow and the survival rate of plant breeding is increased because the Eupatorium adenophorum is added to the raw materials.

Description

Technical field [0001] The present invention relates to the field of plant cultivation. Specifically, the present invention relates to a seedling raising substrate block and a preparation method thereof. Background technique [0002] With the globalization of the world economy and the development of international trade liberalization, invasive alien species pose a serious threat to my country's food security, ecological security, and human and animal health, and seriously endanger the sustainable development of agriculture, forestry, animal husbandry, and fishery. According to investigations, there are 188 species of alien plants that have invaded our country. Some of these malignant invasive plants, such as yellow chrysanthemum, Eupatorium adenophorum, Mikania, airplane grass, guayule, Tribulus terrestris, Eryngium sinensis, etc. Disaster. [0003] Many departments in my country have conducted research on invasive plants. The main methods used to control invasive plants are manua...
