Problems solved by technology

[0005] In recent years, black soldier flies have been more and more widely used in circular agriculture, but there is no relevant research on the relationship between black soldier fly manure and Lietan; and organic fertilizers are often used in planting systems to increase soil organic matter, structure stability, water holding capacity and cation exchange capacity, and serves as a good source of nutrients

Effect test

Embodiment 1

[0026] Inhibitory effect of the insect manure organic fertilizer provided by the invention on the germination of lentils.

[0027] In the present example, the inhibition of the germination of lentils will be described by means of a petri dish test. The petri dish test is to use the artificial hormone GR24 instead of the plant hormone strigolactone (Strigolactone) to study the allelopathic effect of black soldier fly feces on sunflower radon indoors. The test picture of the test is as follows Image 6 shown.

Embodiment approach

[0028] The specific implementation method is as follows:

[0029] 1) Liedang seed pre-cultivation: punch glass fiber filter paper into small circular pieces, lay a layer of ordinary filter paper on the glass plate, soak it with water (without gravity water), stack the small pieces of glass fiber filter paper next to the bottom one by one, and spread them regularly Fill the entire bottom of the dish. Sprinkle the sunflower row seeds evenly with gaps on the bottom, place them in an incubator at 28°C, and culture them in the dark for four days to prepare for germination.

[0030] (40-100 capsules per tablet).

[0031] 2) Preparation of insect manure bio-fertilizer: Grind 1 g of black soldier fly manure, add it to 9 mL of methanol solution, oscillate and mix, then ultrasonicate for 30 minutes, then centrifuge, and filter the obtained supernatant with a filter membrane (0.22 μm) to filter the extract to sterilize, freeze-dry to obtain the extract,

[0032] 3) Put a piece of glas...

Embodiment 2

[0048] Inhibitory effect of the worm dung organic fertilizer provided by the invention on the growth of the germ tubes of Liedang.

[0049] In the present embodiment, the inhibition of the germ tube growth of Liedang is illustrated by the petri dish swing test; the test diagram of the swing test is as follows Image 6 shown.

[0050] Concrete implementation method is, the same as the method of embodiment 1, demonstrates with petri dish pendulum test, and observes Liedang germ tube germination inhibition germination rate and growth length physical figure with microscope; The result is as follows figure 2 with image 3 shown.

[0051] figure 2 middle:

[0052] Small letters indicate that the germ tube length of 0-1mm is the ratio of germ tube length to the number of germination, and the difference is significant (P<0.05) by Duncan analysis. Capital letters indicate the ratio of germ tube length of 1-3mm to the number of germination. (P<0.05).

[0053] Treatment group is ...

Abstract

The invention belongs to the technical field of organic fertilizers and relates to a frass organic fertilizer for restraining broomrape, and a preparation method and a usage thereof. The frass organicfertilizer is prepared from Hermetia illucens frass and methyl alcohol. The frass organic fertilizer is an extract of the Hermetia illucens frass in the methyl alcohol and is prepared by the method:the Hermetia illucens frass is smashed and then mixed with a methyl alcohol solution by vibration, the extract is obtained through freeze drying of a supernate obtained by ultrasonic separation, and an addition amount of the Hermetia illucens frass is 1g Hermetia illucens frass / 9 mL methyl alcohol; and Stratiomyidae frass can be used for restraining germination of the weed broomrape, growth of germ tubes of the weed broomrape and germination and parasitism of Orobanche Cumana. According to the fertilizer, through joint effects of the Hermetia illucens frass and the methyl alcohol, germinationof the broomrape and growth of the broomrape germ tubes can be effectively restrained, the germination and parasitism of Orobanche Cumana can also be restrained, nutrient losses in a plant root systemcan be prevented, a plant death rate is reduced, and the yield and quality of plants are improved.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, and relates to an insect excrement organic fertilizer for suppressing rabies, a preparation method and application thereof. Background technique [0002] According to statistics, since 1991, millions of hectares of land have been destroyed, and the annual loss is estimated to be billions of dollars. Because Liedang lacks some functional organs, such as functional roots and leaves, it completely relies on the root system of the host plant to absorb the nutrition of the host to meet its own growth needs, which will cause the host plant to wilt, stunt growth and even die. [0003] When the sunflower parasitizes the host plant, the sunflower plants will be short, the stems will be thin and weak, the leaves will be small and yellow, and the flower discs will be small, the quality of the seeds will be poor, and the oil content will be low. Eventually lead to the death of the last whole...
