Embodiment 1

[0075] Effects of feces of different beetles on the disease resistance of different plants

[0076] The feces of beetle larvae and dung beetle larvae were collected respectively, and chicken manure organic fertilizer was used as a control.

[0077] Half a month before sowing, apply the manure of white star beetle larvae, insect manure of dung beetle larvae, and chicken manure at a rate of 200 kilograms per mu, and then plow the ground, water it, and organize the cultivated land. Sow rice during the sowing season. 0.1 mu of land for each treatment, repeated 3 plots. All treatments are managed in the same way.

[0078] All treatments were not inoculated with pathogens or applied fungicides, and were compared using the method of natural occurrence of diseases.

[0079] In the treatment group and the control group, 5 points were randomly selected, each point was about 1 square meter, and the incidence was counted before harvesting.

[0080] Statistics on common diseases in cro...

Embodiment 2

[0093] Effects of feces of different beetles on insect resistance of different plants

[0094] In the treatment group and the control group in Example 1, 5 points were randomly selected, each point was about 1 square meter, and investigated once every 15 days, and the insect population was counted.

[0095] Statistics on common piercing-sucking mouthparts and chewing mouthparts pests in crops, including anti-piercing-sucking mouthparts pests: aphids, whiteflies, rice planthoppers, red spiders, mirid bugs, thrips, leaf Cicadas, etc.; chewing mouthparts pests: diamondback moth, corn borer, rice stem borer, cotton bollworm, beet armyworm, tobacco budworm, Spodoptera litura, great ape beetle, flea beetle, leafminer, etc. The weighted insect population was used as the basis for the occurrence of insect pests.

[0096] The calculation method of the insect population reduction rate is: the insect population reduction rate=(the number of insect populations in the control group-the nu...

Embodiment 3

[0100] Field use of beetle dung

[0101] Collect the excrement of the white star beetle larvae.

[0102] Tomatoes were used as the test plants. At the end of the season, the appropriate application rate of insect manure for plant resistance induction was analyzed by counting the incidence of the plants.

[0103] Each treatment was 0.1 mu, and 3 plots were repeated.

[0104] Half a month before sowing, the manure of the larvae of the white star beetle was applied according to 0 kg, 50 kg, 100 kg, 300 kg, and 400 kg per mu.

[0105] Others are the same as embodiment 1.

[0106] The results showed that, compared with no use of insect manure fertilizer, with the increase of insect manure application, the plant growth gradually improved ( image 3 ), and the incidence decreased.

[0107] Such as Figure 4 As shown, after 200 kg per mu, the disease resistance stabilized at a better level.

Abstract

The application of the invention relates to a fecula extract, a preparation method thereof, and an application of the fecula extract to plants. In the preparation method of the fecula extract, the fecula extract is from faeces produced by Scarabaeoidea insects. The preparation method comprises the following steps of 1) mixing dry faeces of which the water content is 3% or below with a solvent to obtain a mixture, adjusting the pH value of the mixture till the mixture is alkaline, and performing high-temperature treatment for 20 to 60 minutes to obtain treating liquid; 2) adjusting the pH value of the treating liquid till the treating liquid is neutral, and performing sedimentation under environment temperature for 5 minutes to 48 hours to obtain a coarse supernatant; and 3) further performing solid-liquid separation on the coarse supernatant so as to obtain a supernatant containing the fecula extract. In addition, the application of the invention also provides an application of the fecula extract and / or the faeces produced by the Scarabaeoidea insects to plants.

Description

technical field [0001] The present invention relates to insect excrement, its preparation method and its application in plants. Background technique [0002] The food problem is one of the difficult problems facing the world today. To increase food production by increasing unit yield or expanding planting area, increasing agricultural input to transform low-yielding fields, etc., will encounter the problem of overcoming adversity constraints or mitigating adversity damage. There are two main types of adversity that limit plant growth and development: biotic stress and abiotic stress, in which biotic stress is mainly pests and diseases, and abiotic stress is mainly drought. With the economic development of human beings, the expansion of population and the destruction of biological populations, plant diseases and insect pests and water shortages are becoming more and more serious. These factors have seriously affected agricultural production and ecological environment, and ha...
