From Table 2, it can be seen that chemicals treatment has certain preventive effect to wheat aphid.1d after medicine, wheat ear aphid insect population
Decline rate is 35.5%, and preventive effect is 19.4%；3d after medicine, check plot worm amount substantially increases, and the reduction for the treatment of region Revision insect recluced rate is aobvious
Write, be 55.0%, preventive effect is 40.0%；5d after medicine, the preventive effect for the treatment of region wheat ear aphid is 86.8%.Result above shows, 50% fluorine
Sulfoxaflor water dispersible granules helicopter dispenser has obvious control effect to wheat ear aphid.
The wheat ear aphid preventive effect of table 2 is investigated
Unit：Head/hundred plant
2.3 wheat scab preventive effects are investigated
Wheat scab investigation result is shown in Table 3.
As can be seen from Table 3, wheat scab generation in check plot is heavier, and average disease index flies anti-processing medium and small up to 9.5
The average disease index of wheat head blight is 1.1, and the preventive effect to wheat scab is 88.4%.Thus, 430g/L tebuconazole suspension concentrates fly
Machine dispenser has preferable control effect to wheat scab.
The wheat scab preventive effect of table 3 is investigated
2.4 wheat powdery mildew preventive effects are investigated
4 are shown in Table to the investigation of wheat powdery mildew preventive effect.
As can be seen from Table 4, fly wheat powdery mildew in anti-processing to be controlled effectively.Wheat powdery mildew is put down in check plot
Equal disease index is 11.1, and it is 1.0 to fly the average disease index of anti-treatment region wheat powdery mildew, far below check plot, processing
Area's 430g/L tebuconazole suspension concentrates are 90.4% to the preventive effect of wheat powdery mildew.
The wheat powdery mildew preventive effect of table 4 is investigated
2.5 determination of yield
5 are shown in Table to wheat yield investigation.
As can be seen from Table 5, wheat reckons the actual amount after a discount yield for 471.27kg/ mus in control treatment, flies wheat in anti-processing and rolls over
Real yield is 562.62 kg/ mus, higher than control treatment, and rate of growth is in 19.38%, obvious effect of increasing production, mainly with flying anti-place
Thousand grain weight of wheat is relevant higher than control treatment in reason.
2.6 pairs of crops and the influence of other beneficial organisms
Observation post administration is applied to wheat without poisoning, in harvesting wheat early stage, compared with check plot, flying defence area wheat leaf blade is still
Green, stalk is healthy and strong；Other beneficial organisms are had no significant effect.
The different disposal wheat yield of table 5 is investigated
3 analyses and discussion
This experiment, by using 3 kinds of different types and size shower nozzle and science collocation is carried out to it, effectively control mist
Particle diameter is dripped, anti-droplet drift, the purpose for promoting droplet sedimentation, improving helicopter prevention effect, the sprinkling droplet of this experiment is reached
Particle size, coverage density of droplets, Droplet deposition and the droplet uniformity are preferable, give full play to the medicine of insecticide and bactericide
Effect, prevention effect reaches more than 85%, while the addition for passing through fertilizer so that it is still green to fly anti-wheat stalk before harvest.It is small
Three proofings technology is sprayed in wheat head phase progress one increases wheat per mu yield effect substantially, flies to prevent that can reach preventing and treating volume increase substantially requires, can
It is widely applied.
This flusher is small in multiple areas such as 2014-2016 Laizhou City of Shandong Province, Tengzhou City and Henan Province Hua County
The arrangement mode of spray bar length, the type and quantity of different shower nozzles is optimized in the spray three proofings of wheat one, makes different medicaments
