Description
Technical field
The present invention relates to technical field of pesticide preparations, and in particular to a kind of water-absorbing-retaining sustained-release pesticides and preparation method thereof.
Background technique
In agricultural production, water and pesticide are an important factor for ensureing agricultural production and income, by control crop growth period
The demand of moisture, can effectively facilitate the growth of crop, especially arid area, and the water-absorbing-retaining ability of soil just seems more
Exacerbation is wanted.That there are effective component rate of release is fast for traditional conventional type pesticidal preparations, drug effect efficiency time is short, dosage is big etc. lacks
Point generally only has 20%-30% especially with rate.In order to maintain certain drug effect, must just spray higher than effective dose of medicine
Amount, or increase spraying times.It is both also easy to produce phytotoxicity in this way, increases pesticide residue, endangers human health, pollution environment, and take a lot of work
It is time-consuming, it is very uneconomical.To solve the above problems, require people to existing pesticide processing dosage form and formula and method of administration not
It is disconnected to improve.Most economical method reasonably be according to the pests occurrence rule of harmful organism, harmful characteristics and environmental condition, make pesticide according to
The dosage that needs, specific time continual and steady release, to reach most economical, safely, effectively control the mesh of harmful organism
's.For this purpose, the concept of sustained-release pesticides is come into being.In simple terms, sustained-release pesticides technology is exactly to be made using physically or chemically means
Pesticide active ingredient is stored in high-molecular compound or other carriers, and is released slowly.Therefore in order to promote crop
Growth, the decrement synergy for increasing the water absorbing and retaining properties and pesticide of soil just seems extremely urgent.
In a kind of preparation method of water-retaining type sustained release pesticide granules of patent announcement CN106035321A.Including following step
It is rapid: pesticide activity component, high molecular material, water-retaining agent and filler material to be mixed, stirring is added solid-liquid mixing and sets to being uniformly mixed
In standby, auxiliary agent and water are added under stirring, is tentatively mediated, extruding kneader is conveyed into using conveying device, and
Water is added and carries out secondary kneading, is granulated, the particle that being granulated terminates to obtain passes through drying, sub-sieve, is packaged to be pesticide granules
Finished product.But pesticide granules finished product reaches water-holding slow-release purpose only by high molecular material and water-retaining agent, and function and effect are limited.
A kind of pesticide multiplexing spansule is disclosed in patent announcement CN107136061A, for controlling formulation rate,
Include at least two mutually isolated utricules including capsule, be filled with different pesticide activity components in different utricule cavitys,
In addition to pesticide activity component, also contain the ingredient of following parts by weight: 10-30 parts of cellulose, 3-10 parts of surfactant, crosslinking agent
2-6 parts, 5-10 parts of water-retaining agent, 30-50 parts of kaolin, 10-20 parts of sodium bicarbonate.The spansule slow release effect is mentioned
It rises, but Water-saving effect is general.

Then slow release drug, compound fertilizer and swells agent is added in slurry into slurry；It is quickly granulated after stirring, then with 84 DEG C
Temperature drying, obtain sandwich layer；
(4) it after mixing coatings raw material components according to mass ratio, is added in tank reactor, is warming up to 62 DEG C, instead
Should keep 38min, obtain coating agent, coating agent and the sandwich layer of upper step are mixed according to the mass ratio of 1:5, in blender with
The revolving speed of 330r/min stirs 6.5min, obtains wrapping layer, then dry with 36 DEG C of thermostatic, obtains water-absorbing-retaining sustained release
Pesticide.
Comparative example 1
This example the difference from embodiment 1 is that, the wrapping layer of sustained-release pesticides is removed.
Comparative example 2
This example the difference from embodiment 1 is that, the compound fertilizer in sandwich layer is removed.
Comparative example 3
This example the difference from embodiment 1 is that, swells agent is saved.
Comparative example 4
This example is that coating drug eliminates coated fertilizer processing with the difference for implementing 1.
Performance test
1, using tangerine orange as planting experiment sample, examination citrus seedling is colonized 2 years, and planting density is 60 plants per acre.It is experimental field every
Year, Cultivate administration was consistent, and crop growing state is suitable, applies the sustained-release pesticides of embodiment 1-5 and comparative example 1-3 respectively, is contained with measuring soil
Water obtains following statistical result:
Table 1: different disposal soil moisture content
As can be seen from Table 1, it in five months after test, is influenced, soil by external environment (rainfall and manual priming)
Water content is all varied, but embodiment 1 will be high compared to comparative example 1-3 soil moisture content, it is seen then that the slow-release fertilizer of the present embodiment
After material is manured into soil, there is improving effect for soil, soil moisture can be adjusted, improve retention capacity of soil, soil moisture conservation is taked precautions against drought.
Changed by test data, it is also seen that the slow release fertilizer performance efficacy window of the present embodiment is longer.
2, sustained-release pesticides in the present embodiment 1 and comparative example 1, comparative example 4 are tested as the sample of planting experiment using jonquil
Insecticidal effect, respectively using red spider, aphid and coccid as statistics insect pest type, count each group sample vermins-proof effect,
It in vermins-proof effect statistics, does not find that pest is denoted as " ++ ", find but does not cause insect pest to be denoted as "+" plant, infection insect pest is denoted as
"--"；And the drug effect duration of each group sample is counted, obtain following test result:
Table 1: the vermins-proof effect statistics of the jonquil of each group embodiment in the present embodiment
| Test item | Red spider | Aphid | Coccid | The drug effect duration/the moon |
| Blank control group | -- | -- | -- | \ |
| Embodiment 1 | ++ | ++ | + | 12 |
| Comparative example 1 | ++ | ++ | + | 6 |
| Comparative example 4 | ++ | ++ | + | 3 |
It analyzes above-mentioned test result to find, the drug of the present embodiment and control group all has protection effect to most of insect pest
Fruit, blank control group are more serious due to the problem of not applying drug, infecting insect pest.By the present embodiment 1 and comparative example 1,3
It is found after comparing, the drug effect phase of drug is obviously prolonged in medicine fertilizer particulate matter provided by the invention, has and stablizes the lasting drug effect phase.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
