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] Embodiment 1, preparation is the seedling raising matrix piece that takes alien invasive plant as raw material

[0025] Specific preparation process:

[0026] 1) The main ingredient made by adding invasive alien plant stems: screen and test the alien invasive plant stems, carry out composting and fermentation, then crush and sort the alien invasive plant stems, and carry out reasonable particle grading (1~ 3mm particle gradation accounts for 45% to 55%), remove excess ash and large blocks, make the particle size of the material consistent, uniform physical and chemical properties, and then dry to the water content 3 , water holding capacity > 400%, 1 ~ 3mm particle gradation > 50%, roundworm egg mortality > 95%, coliform value < 1 / 10, redox potential value (Eh) 200 ~ 600mV. The invasive alien plants are Eupatorium adenophorum, chrysanthemum, mikania micrantha, planegrass, guayule, tribulus terrestris or black nightshade, accounting for 20% of the total amount of main in...

Embodiment 2

[0034] Embodiment 2, the preparation of the seedling-raising substrate block with alien invasive plants as raw material

[0035] The stems of alien invasive plants Eupatorium adenophorum, yellow top chrysanthemum, Mikania micrantha, airplane grass, guayule, Tribulus terrestris or Solanum echinacea account for 50% of the total amount of main ingredients, and mud (grass) charcoal accounts for 50% of the total amount of main ingredients. 50%; Other preparation steps are with embodiment 1.

Embodiment 3

[0036] Embodiment 3, prepare the seedling-raising substrate block that takes alien invasive plant as raw material

[0037] The stems of alien invasive plants Eupatorium adenophorum, yellow top chrysanthemum, mikania micrantha, planegrass, guayule, Tribulus terrestris or Solanum echinacea accounted for 35% of the total amount of main ingredients, and mud (grass) charcoal accounted for 35% of the total amount of 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 invention relates to the field of plant planting, in particular, the invention relates to a seedling raising substrate block and a preparation method thereof. Background technique [0002] With the development of world economic globalization and international trade liberalization, alien invasive 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 the survey, there are 188 kinds of alien plants that have invaded our country, some of which are vicious invasive plants such as chrysanthemum, Eupatorium adenophorum, Mikania micrantha, airplane grass, guayule, tribulus terrestris, and nightshade. Disaster. [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 chemica...
