A, solid potato culture medium is made to flat board, inoculation medium quality 0.8%-1.2% Trichoderma harzianum, 25 DEG C of cultures 3d, obtains liquid culture；

B, bagasse 30-40, wheat bran 30-35, rice bran 30-35 are taken in mass ratio, tune its water content of adding water is 55%-65%, is obtained Solid medium, solid medium is mixed with liquid culture example 4-6: 1 in mass ratio, 25-30 DEG C of keeping temperature, cultivates 5- Produce Trichoderma harzianum culture within 7 days；

（2）The processing of agricultural crop straw：

By crops stalk crushing into broken section of 1-3cm, in steam pressure 2.3-3.5MPa, dwell time 100-200s technique Under the conditions of Steam explosion treatment；

（3）Fish pond mud is dried at 80-100 DEG C to moisture below 12%, by the mass ratio take drying fish pond mud, Amorpha fruticosa leaf powder, pine needle meal, kaolin mixing, obtain mixture, add mixture quality 1%-3% earthworm kind, add water regulation Its water content is 55%-65%, lucifuge culture 5-8 weeks, the Trichoderma harzianum culture with the mass ratio, treated crops straw Stalk, river sand, bamboo charcoal, potassium humate mixing produce sealwort cultivation matrix.

Beneficial effects of the present invention：

Cultivation matrix of the present invention is nutritious, fish pond mud used, amorpha fruticosa leaf powder, pine needle meal organic matter protein, micro member Cellulose content is high, and miscellaneous bacteria is killed by drying fish pond mud, is added after mixing fish pond mud, amorpha fruticosa leaf powder, pine needle meal, kaolin Earthworm is cultivated, and will hold labile nutritional ingredient and is converted into more stable wormcast, also, combines Trichoderma harzianum culture, place Agricultural crop straw, river sand, the bamboo charcoal managed, improve the physicochemical property of matrix, improve the gas permeability of matrix, increase the fertilizer conservation of matrix Water holding capacity, it is often more important that, agricultural crop straw is easily decomposes under the activity of earthworm after Steam explosion treatment, promotes base Material is circulated in matter, is improved matrix biopolymers activity, is promoted the breeding of Trichoderma harzianum, improves the biocontrol effect of matrix, can be notable Improve growing for sealwort, improve the quality of sealwort.

Embodiment

With reference to specific embodiment, the present invention is described in further detail.

Embodiment 1

The preparation method of sealwort cultivation matrix of the present invention, including herein below：

（1）The preparation of Trichoderma harzianum culture：

A, the distilled water of 20 times of commercially available solid potato culture medium and its quality mixed, 120 DEG C of sterilizing 20min, in culture dish In be made flat board, the commercially available Trichoderma harzianum of inoculation medium quality 1.2%, 25 DEG C of culture 3d obtain liquid culture；

B, bagasse 40, wheat bran 35, rice bran 35 are taken in mass ratio, tune its water content of adding water is 65% to obtain solid medium, by this Solid medium is mixed with aforesaid liquid culture example 6: 1 in mass ratio, 30 DEG C of keeping temperature, and culture produces Trichoderma harzianum in 7 days Culture；

（2）The processing of agricultural crop straw：

By crops stalk crushing into broken section of 3cm, the steam under steam pressure 3.5MPa, dwell time 200s process conditions Explosion treatment；

（1）Fish pond mud is dried to moisture at 100 DEG C below 12%, fish pond mud 50kg, the amorpha fruticosa leaf powder of drying is taken 8kg, pine needle meal 10kg, kaolin 10kg mixing, it is 65% to adjust its water content, adds 2.3kg earthworm kinds, lucifuge culture 8 weeks Afterwards, mixed with 5kg Trichoderma harzianums culture, treated agricultural crop straw 30kg, river sand 60kg, bamboo charcoal 15kg, potassium humate 8kg Conjunction produces sealwort cultivation matrix.

The experiment in cultivation of the present invention of embodiment 2

With general planting soil for control group, matrix of the present invention is test group, using the cm of Φ 20, high 20 cm round plastic flowerpot Substrate culture is contained, is planted per basin on 3 sections of rhizomes, every section of rhizome containing 2 ~ 3 full buds, control group and each 10 basin of test group. Two groups of same environmental conditions, unified water and fertilizer management.

Index determining

After plant to be planted growth stops, the ground height of plant is measured, its average value is taken as the average plant height of the group；From start exhibition Ye Qi, counts 1 every group of total number of blade, untill double surveyed blade is not further added by, with the total leaf of the group every 3 d Piece number tries to achieve every plant of average leaf number；Leaf area：After the blade of all plant stops growing, every group is measured with leaf area instrument The gross area of P. involucratum blade, takes its average value as the gross area of single-strain blade；Bloom number of bearing fruit：Since being buddingged inflorescence Before being withered to flower, the flower number of every group of statistics takes its average value as the number of blooming of individual plant；After fruit maturation, statistical average Every plant of number of results；Count the leaf spot incidence of disease, the charcoal myiasis incidence of disease of sealwort in whole growth period：

	Control group	Test group
			Plant height（cm）	35.84	46.73
The number of blade（Piece）	13.88	16.29
			Leaf area（cm2）	22.36	31.54
Bloom number（Piece）	18.57	23.69
			Fruit-setting rate	4.3%	7.24%
The leaf spot incidence of disease	15.6%	3.6%
			The charcoal myiasis incidence of disease	8.9%	2.3%

As can be seen that relative to control group, the plant height of test group adds 30.4%, and the number of blade adds 17.36%, blade face Product adds 41.1%, and number of blooming adds 27.6%, and fruit-setting rate adds 2.94 percentage points, and the leaf spot hair of control group Sick rate is 4.33 times of test group, and the charcoal myiasis incidence of disease is 3.87 times of test group.
