Application effect example：
1st, test method
Reference《NY/T 1155.3-2006 farm-chemical indoor determination test rule herbicide third portions：Determination of activity tries Test soil spray-on process》Carry out.
Experiment, which is located under greenhouse experiment, to be carried out.Choose several generations in grassy weed, broad leaved weed and sedge weed Table weeds chickweed, moleplant seed, shepherd's purse, chufa, volume stem smartweed, barnyard grass, Sorghum halepense, lady's-grass, purslane, piemarker, wild oat are For trying weeds.Chufa takes underground rhizome breeding from field, and remaining several weeds breeds from field collection weed seed.
Experiment soil is quantitatively filled at the 4/5 of basin alms bowl.Choose chickweed that is full, uniform, having no mechanical damage, moleplant seed, Shepherd's purse, volume stem smartweed, barnyard grass, Sorghum halepense, lady's-grass, purslane, piemarker or wild oat seed, it is after soaking 24h with clear water, its is uniform Broadcast sowing in the round plastic nutritive cube surface equipped with soil, a diameter of 30cm, broadcast 30~40 per basin, earthing 1.0cm.Chufa Take underground rhizome (long-rhizome such as 3cm) from field, 10 sections are planted per basin.The moisturizing in a manner of the bottom infiltrating irrigation of basin alms bowl, makes soil complete It is complete to moisten to saturation state.The decoction prepared is subjected to soil spraying after sowing 24h.Then move into controllable heliogreenhouse and train Support.Often processing set 4 repetitions, every time repeat 5 basins, using without chemicals treatment as blank control.
21d after chemicals treatment, investigation method investigation records activity of weeding (is counted and surveys) using absolute value, with weighing each processing weeds Upper part fresh weight, actual preventive effect is calculated, and evaluated and acted synergistically according to Colby methods.Referring to COLBY, S.R.：" calculate herbicide The collaboration of combination and Antagonistic reaction ", Weeds 15, p.20~22,1967：
According to survey data, the actual preventive effect of each processing is calculated by formula (1), unit is percentage (%), result of calculation Retain 2 significant digits.
In formula：
E-actual preventive effect；
C-control weeds aerial part fresh weight；
T-processing weeds aerial part fresh weight.
Colby methods：Theoretical preventive effect (it is expected that preventive effect) E of Mixed Pharmacy0(2) formula calculates：
In formula：
Actual preventive effect when the dosage of X-herbicide 1 is P；
Actual preventive effect when the dosage of Y-herbicide 2 is Q；
Actual preventive effect when the dosage of Z-herbicide 3 is R；
E0The dosage of-herbicide 1 is that the dosage of P+ herbicides 2 is theoretical preventive effect when the dosage of Q+ herbicides 3 is R, i.e. mixture is removed The expection preventive effect of careless agent；
E-herbicide 1,2 and 3 presses actual preventive effect during different ratio mixture；
As E ＞ E0When, i.e., if the actual preventive effect of Mixed Pharmacy exceedes the theoretical preventive effect (it is expected that preventive effect) calculated, then should Combination just has super superposition, that is, acts synergistically.
2nd, result of the test
