Embodiment 20
Place：Jiangxi Province's Ji'an City
Test period：On May 23rd, 2015
The peanut varieties that this experiment adopts spend No. 14 for Shandong, and peanut seed selects clean, full, no disease pest seed, use
In the embodiment of the present invention 1～13, the seed coat agent of gained is sowed to basin alms bowl after processing, 3 plants of every basin.Train in controlled heliogreenhouse
Support, each process keeps good consistent water and fertilizer management.Each is processed with clear water as blank.
Data survey and statistical analysis
Variable color：Observe crop leaf discoloration, record discoloration and variable color blade account for for studying the whole blade of thing
Ratio, and whether variable color can recover and recover the information such as required number of days.
Necrosis：Crop different parts organ necrosis situation, record occur spot or necrosis organ account for whole for studying thing
The ratio of organ, and spot or necrosis area account for the ratio of crop organ's area.
Wilt：Wilting symptomatic condition in crop leaf, and record the wilting symptom time and wilts the duration, if
Can recover and recover the information such as required time.
Deformity：Crop plant tiller is abnormal, grow adventitious root, lateral growth, excessive growth, leaf rolling or torsional deformation, stem
Situations such as contracting, the flower spike of hanging deforms, record produces the plant quantity of deformity and accounts for the information such as the ratio of whole plant.
Growth inhibition：The measurement of plant height, the measurement of vegetative growth phase Security test plant height, with peanut bottom for end points extremely
Peanut top is peanut plant height；The measurement of reproductive stage Security test plant height, with peanut bottom for end points to peanut
Top is peanut plant height.
Growth inhibition is investigated, and after dispenser, 7 days situations of emerging to peanut count, 21 days plant heights to peanut after dispenser
Measure, the information such as record suppressed situation of peanut growth.
Growth rate inhibiting rate and the computing formula of emergence rate：
Growth rate：R=L/D
R is growth rate (mm/d), and L is the newborn height of plant or length (mm), and D is time sky (d).
Growth rate inhibiting rate (%)：I=(Rck-Rt)/Rck × 100
I is growth rate inhibiting rate (%), and Rck is blank growth rate, and Rt is the growth rate of chemicals treatment.
Emergence rate (%)：P1=n1/n2 × 100
P1 is emergence rate (%), and n1 is number of emerging after chemicals treatment, and n2 is sowing total number.
Fallen flowers rate increment rate (is only applicable to reproductive stage Security test)
2 plants of peanut fringes randomly drawed by every basin, respectively record fallen flowers number number and training peanut fringe spend sum.As follows
Carry out Data Management Analysis：
Fallen flowers rate (%)：P2=n3/n4 × 100
P2 is fallen flowers rate (%), and n3 is fallen flowers number, and n4 is flower spike sum.
Fallen flowers rate increment rate (%)：I=(T-C)/T × 100
I is fallen flowers rate increment rate (%), the fallen flowers rate (%) that T is processed for seed coat agent, and C is blank fallen flowers rate (%).
The present invention, after packing Germinating Peanut Seeds, in area discoloration, necrosis such as vegetative growth phase observation crop leafs, withers
Listless and lopsided symptomatic consequence record is shown in Table 1, and peanut reproductive stage measurement result is shown in Table 2.
The present invention investigates growth and emerges and suppression situation, and peanut emerges original data record and growth emergence rate etc. is processed
The results are shown in Table 3, peanut plant height original data record and growth inhibition ratio etc. process and the results are shown in Table 4, peanut fallen flowers initial data

The seed coat agent that the present invention provides as can be seen from Table 5 is less for the impact of peanut reproductive stage fallen flowers rate, institute
The seed coat agent stated is safer.
During whole test, seed coat agent is existing to all no obvious poisoning of peanut varieties under the preparation dosage of experimental design
As producing, chemicals treatment district fresh branches and leaves of peanut seedling energy normal growth is simultaneously solid, not bright with the fresh branches and leaves of peanut seedling upgrowth situation in blank district
Significant difference is different.Show, seed coat agent is safe to peanut, can be applicable on peanut.
As seen from the above embodiment, the seed coat agent that the present invention provides is due to the addition of liquefied fiber polysaccharide, it is to avoid aromatic hydrocarbons
The use of solvent, the environmental pollution being brought by wall material during reducing the applications of pesticide；And be former with the animal origin polysaccharide that liquefies
Material so as to get seed coat agent biodegradable strong, have the advantages that easy, rate of release swift to operate is controlled.By the present invention
The seed coat agent providing is used for Seed Treatment, and pesticide active ingredient can be attached on seed, reduces what agricultural chemicals was sprouted to seed
Impact, the preparation method of seed coat agent of the present invention can also control pesticide active ingredient by adjusting the composition of preparation liquid A
Release time and speed, reach accurate spraying time, compared with Seed Treatment dry powder doses, under same effect reduce agricultural chemicals have
The consumption of effect composition.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
