Deformity：Crop plant tiller is abnormal, grow adventitious root, lateral growth, excessive growth, leaf rolling or torsional deformation, stem
Contracting, spica hang situations such as deform, record produces the plant quantity of deformity and accounts for the information such as the ratio of whole plant.
Growth inhibited：The measurement of plant height, the measurement of vegetative growth phase Security test plant height, with Semen arachidis hypogaeae bottom as end points extremely
Semen arachidis hypogaeae top is Semen arachidis hypogaeae plant height；The measurement of reproductive stage Security test plant height, with Semen arachidis hypogaeae bottom as end points to Semen arachidis hypogaeae most
Top is Semen arachidis hypogaeae plant height.
Growth inhibited is investigated, and after dispenser, 7 days situations of emerging to Semen arachidis hypogaeae are counted, 21 days plant heights to Semen arachidis hypogaeae after dispenser
Measure, the information such as suppressed situation of record peanut growth.
Growth rate suppression ratio 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 day (d).
Growth rate suppression ratio (%)：I=(Rck-Rt)/Rck × 100
I is growth rate suppression ratio (%), 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 to emerge number after chemicals treatment, and n2 is sowing total number.
Fallen flowers rate increment rate (is only applicable to reproductive stage Security test)
2 ZHUHUA life fringe is randomly selected per basin, and record fallen flowers number number and training Semen arachidis hypogaeae fringe spend sum respectively.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 spica sum.
Fallen flowers rate increment rate (%)：I=(T-C)/T × 100
I is fallen flowers rate increment rate (%), and T is the fallen flowers rate (%) that seed coat agent is processed, and C is blank fallen flowers rate (%).
