Above-mentioned oil-suspending agent is applied to transplanting rice field, 165 grams/acre, in south rice field, paddy rice 3 leaf phase cauline leaf spraying after seedling, to barnyard grass, moleplant seed preventive effect more than 85%, but to the paddy rice underproduction about 30%.
Field control effectiveness test is reported
One, test objective
Carry out the raw test of field efficacy to the medicament provided to test, provide medicament to the control efficiency of paddy field weed for clear and definite, and then provide scientific basis for production application from now on.
Two, test method and investigation
2.1 trial crops: paddy rice;
2.2 dispenser places, time and method;
Process 1-9: place: Qing Yuan town, Baoqing County, Heilongjiang Province, application method: be watered evenly thorn before transplanting for 3-5 days and slip;
Process 10-20: place: Qing Yuan town, Baoqing County, Heilongjiang Province, application method: mix soil in 7-10 days after transplanting and evenly spread fertilizer over the fields;
Process 21-31: place: Qing Yuan town, Baoqing County, Heilongjiang Province, application method: paddy rice 3 leaf 1 heart is evenly cauline leaf spraying later;
Process 32-36: place: Hubei Province Suizhou City Suixuan County, application method: uniform soil spraying before after broadcasting;
Process 37-39: place: Xinyang City, Henan Province, application method: paddy rice 3 leaf 1 heart is evenly cauline leaf spraying later;
2.3 investigation method;
2.3.1 investigation method takes diagonal formula 5 sampling, often some investigation 0.2m2, and each community investigates weed population quantity respectively, and investigation statistics, based on main weeds population, calculates strain preventive effect.During results, random each process sampling 5 points, measure output, calculating mean value respectively.
2.3.2 control time and number of times;
Process 1-9: investigate weeds strain preventive effects and crop safety in the 15th day, 30 days after administration respectively;
Process 10-20: investigate weeds strain preventive effects and crop safety in the 15th day, 30 days after administration respectively;
Process 21-31: investigate weeds strain preventive effect and crop safety in the 7th day, the 21st day after administration respectively;
Process 32-36: investigate weeds strain preventive effects and crop safety in the 15th day, 30 days after administration respectively;
Process 37-39: investigate weeds strain preventive effect and crop safety in the 7th day, the 21st day after administration respectively;
2.3.3 to the safety of trial crops;
Whether viewing test medicament impacts the growth of crop, whether causes poisoning to crop late growing stage.
Three, test process
Table 1 reagent agent experimental scheme
Three, result of the test (table)
Table 2 processes 1-20 to the strain preventive effect of paddy field weed and output application form
After the transplanted rice field seedling of table 3 northeast, cauline leaf spraying process is to Weed-control effect and output application form
Before rear seedling is broadcast in the live field of table 4 south rice, soil treatment is to Weed-control effect and output application form
The southern live Tian Miaohou cauline leaf spraying process of table 5 is to Weed-control effect and output application form
Four, conclusion
Can be found out by table 1, significantly increase the herbicidal effect to grassy weed, broad leaved weed and nutgrass flatsedge after gibberellic acid mixes with weed killer herbicide, show volume increase simultaneously.Within 3-5 days, evenly spread fertilizer over the fields each process before transplanting for northeast paddy field, process 7 synergy containing gibberellic acid is the most obvious, preventive effect and the equal amplification of output about 11%.Evenly spread fertilizer over the fields each process within 7-10 days, mixing soil after transplanting, the effect that gibberellic acid shows in herbicidal composition is more obvious, the preventive effect amplification 43% of the relative process of process 12 13 pairs of nutgrass flatsedges, output amplification 29%; Wherein show the most excellent in process 18, variable rate technology is reach 100% to the preventive effect of grassy weed, broad leaved weed and nutgrass flatsedge.
For northeast transplanted rice field, the different application method of different times, containing the effect that gibberellic acid process shows, the most remarkable with cauline leaf spraying process synergy after seedling, process 22,24,26,28 is not containing gibberellic acid, field all shows poisoning in various degree, and finally causing the underproduction of crop, process 22,24 is the most obvious, and the underproduction reaches 45%, 16% respectively, the not serious poisoning of process 22,24 performance, processes 26 pairs of paddy rice and causes obvious dwarfing.
Can find out for live field, south, before herbicidal composition containing gibberellic acid broadcasts rear seedling, soil spraying process performance synergy is obvious, to the preventive effect of grassy weed, broad leaved weed and nutgrass flatsedge all more than 95%, process not containing gibberellic acid causes rice seedling rate to decline, there is underproduction situation, be respectively 4.4%, 19.4%.After seedling, cauline leaf spraying process also shows better safety and the guarantee to product, and for adding the process 38 of gibberellic acid, serious symptom of chemical damage appears in paddy rice, causes the underproduction 24%.Gibberellic acid and part herbicidal composition itself have synergistic effect for weed killer herbicide weed control, and can improve the safety of weed killer herbicide to crop, by regulating crop growth, improve crop yield.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the claims in the present invention.
