Problems solved by technology

At present, it breeds and grows in many waters in our country, floating on the water surface in large numbers, blocking the river course, seriously affecting shipping and water operations; at the same time, reducing the penetration of sunlight to the water body, affecting the growth of underwater organisms and increasing the concentration of carbon dioxide in the water body, polluting water quality
Seriously affect the output and quality of aquatic products
Due to the strong reproductive ability of water hyacinth, mechanical salvage methods have been used for many years, but they cannot be cured; in recent years, some units have developed water hyacinth killers, but they are all chemical agents, poisonous, and seriously pollute water bodies.
So far there is no effective and non-polluting water hyacinth killer

Embodiment 1

[0018] Raw Material: Red Pond 38%

[0019] Soy 2%

[0020] Angel Brand Distiller's Koji Active Yeast 1.6%

[0021] water balance

[0022] Preparation:

[0023] (1) Soak the soybeans in water and squeeze the juice to obtain soybean milk, which is set aside;

[0024] (2) Red pond and water were dissolved and boiled for 100 minutes in a weight ratio of 1:1;

[0025] (3) mixing soybean milk with boiled red pond water and remaining water to obtain a mixed liquor;

[0026] (4) Fermentation: add active saccharomyces to insulate and ferment for 30 days when the temperature of the mixed solution is 36°C, to obtain a finished product.

Embodiment 2

[0028] Raw Material: Red Pond 36%

[0029] Soy 2%

[0030] Angel Brand Distiller's Koji Active Yeast 2%

[0031] water balance

[0032] Preparation:

[0033] (1) Soak the soybeans in water and squeeze the juice to obtain soybean milk, which is set aside;

[0034] (2) Red pond and water were dissolved and boiled for 110 minutes in a weight ratio of 1:1;

[0035] (3) mixing soybean milk with boiled red pond water and remaining water to obtain a mixed liquor;

[0036] (4) Fermentation: when the temperature of the mixed solution is 38°C, add active saccharomyces to insulate and ferment for 40 days to obtain a finished product.

[0037] The products obtained in the above two examples are tested: the product has a delicate fragrance, the appearance is a brown transparent liquid, and there is no sediment. PH5.5-7.5. Miscellaneous bacteria rate <5%.

[0038] After the toxicity test by Nanjing Medical University Health Analysis and Testing Center, it is slightly toxic and has n...

experiment example

[0040] Experimental drug: the water hyacinth growth inhibitor used the product obtained in Example 1.

[0041] Experimental method: Spray the growth inhibitor of water hyacinth directly on the leaves of water hyacinth with a sprayer, and the dosage is 50-80g / m 2 (depending on the thickness of the water hyacinth layer), if the seeds or residual roots are sprouting, spray again after 15 days

[0042] Effect: 5 minutes after spraying, the water hyacinth leaves began to curl, 20 minutes later the leaves began to shrink and wither, 60 minutes later the leaves dried up, and two weeks later the stems and roots rotted.

[0043] The above experiments were performed 5 times, and the results are shown in Table 1 (see next page for Table 1).

Abstract

The invention discloses a common water hyacinthes growth inhibitor wherein the constituents of the raw material include (by weight percent) brown sugar 35-38%, soybean 2%, active yeast 1.5-2%, and balancing water. The inhibitor can effectively kill common water hyacinths within short period of time without influencing the growth of other benthos.

Description

technical field [0001] The invention belongs to the technical field of herbicides. Specifically relates to a water hyacinth growth inhibitor. Background technique [0002] Water hyacinth, also known as water hyacinth, is an exotic species and one of the top ten harmful weeds in the world. At present, it breeds and grows in many waters in our country, floating on the water surface in large numbers, blocking the river, seriously affecting shipping and water operations; at the same time, reducing the penetration of sunlight into the water body, affecting the growth of underwater organisms and increasing the concentration of carbon dioxide in the water body, polluting water quality. Seriously affect the output and quality of aquatic products. Due to the strong reproductive ability of water hyacinth, mechanical salvage methods have been used for many years but cannot be cured. In recent years, some units have developed water hyacinth killers, but they are all chemical agents, p...
