Description
Technical field
The present invention relates to a kind of dressing agent for rice, and in particular to a kind of slow release active constituent multifunctional water seed rice clothing
Agent belongs to seed treatment field.
Background technology
In the paddy growth period, it is always often subject to the threat of pest and disease damage, especially rice seedling pest and disease damage is always agriculture
The problem of industry expert and peasant pay special attention to, the prior seeds such as the dressing seed used in the past, seed soaking sterilization method and soil
Sterilization method is handled, and although these methods have certain effect, but effect is not highly desirable；It is using method for soaking seed, medicament is dilute
It releases in water kind, dose is big, and waste is more；Dressing seed is taken to cause to dress seed uneven or damage seed, these methods have one
A common problem is poor adhesive force of the medicament on seed, Habitat or after planting with water when it is easy to fall off, the lasting period is short,
And dosing is big, seed disinfection must carry out in the short time prior to seeding, be difficult to realize the industrialization of seed treatment；Soil disappears
Toxicant dosage is big, of high cost, time-consuming, and environmental pollution is serious.
In the paddy growth period, it is always often subject to the threat of pest and disease damage, especially rice seedling pest and disease damage is always agriculture
The problem of industry expert and peasant pay special attention to, the previous method for applying chemical pesticide using Growing season are handled, but chemical
Prevention prevention often, time-consuming, labor expense, welding.
Invention content
Technical problem to be solved by the invention is to provide a kind of slow release active constituent multi-function agent for coating rice seeds, gram
Method for soaking seed causes dose big, waste is more, and dressing seed causes seed dressing uneven to clothes since medicament to be diluted in water in the prior art
Even or damage seed defect.

Sublist face can be sowed after natural drying, after planting observe the growing states such as germination, emergence and feelings occur for pest and disease damage
Condition.
Not using the seed coat agent capsuled seed of embodiment 4, the dressing agent for rice Cotton seeds seed of comparative example 4 and control group
The seed of Cotton seeds carries out germination percentage (%), percentage establishment of seedling (%), stem weight (mg/ from indoor pot, cell and field trial
Cm), root weight (mg/cm) and seedling bakanae disease, seedling seasonal febrile diseases and rice thrips control effect (%) are investigated, as a result such as the following table 4.
The seed coat agent capsuled seed of 4 embodiment 4 of table, the dressing agent for rice Cotton seeds seed of comparative example 4 and control group are not
The seed-test investigation result of Cotton seeds
From upper table 4 can from obtain, the germination of slow release active constituent multi-function agent for coating rice seeds of the present invention processing
Rate (%), percentage establishment of seedling (%), stem weigh (mg/cm), root weight (mg/cm) is obviously higher by comparative example 4 and control group, well developed root system, and
The quality of rice shoot can be significantly improved, increases photosynthesis, and 96% or more, seedling seasonal febrile diseases are reached to the control effect of seedling bakanae disease
96% or more and rice thrips control effect reach 98% or more.
Inventor is found surprisingly that combination and the spy of guar gum, polyvinyl alcohol and hydroxyethyl cellulose in experimentation kind
Fixed ratio has significant impact to the coating fastness of seed coat agent.
The adhesion rate of embodiment 1 to 4 and comparative example 1 to 4 is tested：Example 1 to 4 and comparative example 1 to 4 respectively
Dressing agent for rice 100g as in round bottom container, 130g moistening rice paddy seeds are added and roll to be coated manually and dry.Weigh 3g packets
Clothing seed, be respectively placed in triangular flask shaken as 5min is shaken in oscillator shaking table rotating speed 180r/min-200r/min it
Between, taking-up is weighed, and adhesion rate is calculated, and experiment is averaged three times, see the table below 5.
The calculation formula of adhesion rate is as follows：
The coating expulsion rate test result of 5 seed coat agent of table
| Adhesion rate | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Comparative example 1 | Comparative example 2 | Comparative example 3 | Comparative example 4 |
| Average value | 98.55 | 98.2 | 98.89 | 95.2 | 72.2 | 81.2 | 78.9 | 62.9 |
Shown in upper table 1 to 5, seed coat agent of the present invention, coating fastness is very good, not easily to fall off after coating, and to seed
Germination not adversely affect, can effectively realize the slow release of fungicide active ingredient and active insecticidal components, be conducive to medicine
The continuous action of property, field experiment prove that the seed coat agent can dramatically increase yield, improving quality.
