Abstract
A chemical for decreasing the damage of agricultural chemical to plants contains brassinolide (0.0018-0.017%), alcohol ((7.4-10.8) between 80 of 98% concentration (1.96-10.2) and water (80-90). It is applied through diluting with water, and spraying it on the leaves of plant. It can also increase the photosynthesis power and resistance.
Description
Technical field
The present invention relates to be used to alleviate the preparation of agricultural chemicals to phyto toxicity.
Background technology
Agricultural production more and more depends on the use of agricultural chemicals such as comprising bactericide, insecticide and weed killer herbicide.Yet, these agricultural chemicals when killing the target pest, also to doing deposits yields influence in various degree, as photosynthetic decline, the shrinkage of blade, the reduction of resistance etc., and this harmful effect is more obvious when similar high temperature, low temperature and arid.Also lack effective method at present and alleviate agricultural chemicals to phyto toxicity, the loss that therefore causes in the production is difficult to estimate.
Summary of the invention
At the deficiencies in the prior art, the purpose of this invention is to provide and a kind ofly can alleviate the preparation of agricultural chemicals effectively phyto toxicity.
The technical solution used in the present invention is, a kind ofly is used to alleviate the preparation of agricultural chemicals to phyto toxicity, and the component and the content of said preparation are as follows:
Brassinosteroid 0.0018%～0.017%
Concentration is 95% alcohol 7.4%～10.8%
Concentration is 98% Tween 80 1.96%～10.2%
Water 80%～90%
All percentages are percetage by weight.
The component of described said preparation and content preferred value are:
Brassinosteroid 0.01%
Concentration is 95% alcohol 10%
Concentration is 98% Tween 80 1.99%
Water 88% all percentages are percetage by weight.
But the brassinosteroid of above-mentioned brassinosteroid synthetic, the also brassinosteroid of natural extract is as brassin lactones, epi-brassinolide etc.
The compound method of reagent:
1. take by weighing each component in proportion;
2. after brassinosteroid being dissolved in alcohol, add Tween 80, be uniformly mixed into solution;
3. the solution of above preparation and water are mixed together evenly and get final product.
Using method: get preparation 10-20 milliliter of the present invention, add 10 liters in clear water, after mixing, evenly spray in the plant leaf blade surface till blade has the globule to form with agroatomizer.Use generally in the morning or carry out at dusk.Use can be in the spraying pesticide pre-treatment, and also can be mixed with agricultural chemicals sprays.Test shows, just can significantly alleviate agricultural chemicals to phyto toxicity after this preparation is used once, and its term of validity is 7-10 days, and access times can be determined according to the operating position of agricultural chemicals.
Preparation of the present invention has the advantage that manufacturing is simple, easy to use, cost is low and have no side effect.Can alleviate degradation bad phenomenon under the photosynthesis that the applications of pesticide cause, use and can improve about photosynthesis of plants 20-40%, about volume increase 10-20%, effect is obvious.Be applicable to crops such as vegetables, fruit tree, flowers, tealeaves.After in greenhouse cucumber, using this preparation, can obviously alleviate the harmful effect of bactericide, insecticide and weed killer herbicide to plant, improve photosynthesis, be adapted at the vast rural area of China and apply.
Embodiment
Below in conjunction with specific embodiment the present invention is described in further detail.
Embodiment 1:
It is as follows to the component and the content of the preparation of phyto toxicity to alleviate agricultural chemicals:
10 milligrams of brassinosteroids (0.01%)
Concentration is 95% alcohol 10 grams (10%)
Concentration is 98% Tween 80 2 grams (1.99%)
Water 88 grams (88%)
Compound method: take by weighing each component according to the above ratio, after elder generation is dissolved in alcohol to epi-brassinolide, add Tween 80, be uniformly mixed into solution, again this solution is mixed together evenly with water.
In the 3 leaf phases of greenhouse cucumber, the next day that sprays bactericide, get 10 milliliters in this preparation, add and evenly spray in the morning after 10 liters in clear water mixes in cucumber leaves surface till moistening.With the Net Photosynthetic Rate is index, and treatment effect and reference examples comparative result see Table 1.
Table 1
| Net Photosynthetic Rate (μ mol m -2s -1) | Individual plant leaf area (cm 2) | |
| Reference examples (not spraying reagent) | 10.3 | 267 |
| Inventive embodiments | 15.4 (49.5％) | 384 (43.8％) |
Annotate: photosynthesis is the measurement result that sprays after a time 2 days, and leaf area is the measurement result after the week, is the increase percentage in the parantheses.
Embodiment 2:
It is as follows to the component and the content of the preparation of phyto toxicity to alleviate agricultural chemicals:
2 milligrams of brassinosteroids
Concentration is 95% alcohol 10 grams
Concentration is 98% Tween 80 10 grams
Water 90 grams
All the other are with embodiment 1.
Embodiment 3:
It is as follows to the component and the content of the preparation of phyto toxicity to alleviate agricultural chemicals:
15 milligrams of brassinosteroids
Concentration is 95% alcohol 8 grams
Concentration is 98% Tween 80 2 grams
Water 80 grams
All the other are with embodiment 1.
At last, it is also to be noted that what more than enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.
The present invention can summarize with other the concrete form without prejudice to spirit of the present invention and principal character.Therefore, no matter from which point, above-mentioned embodiment of the present invention all can only be thought can not limit the present invention to explanation of the present invention, claims have been pointed out scope of the present invention, and scope of the present invention is not pointed out in above-mentioned explanation, therefore, in implication suitable and any change in the scope, all should think to be included in the scope of claims with claims of the present invention.
