The autumn wheat seeding work in 2012 is about to begin. Seriously pre-seeding seed treatment is the basic measure for comprehensive prevention and control of pests and diseases. It is the key to ensuring seedling growth and harvesting and harvesting summer harvests. It is hoped that all towns and villages will do a good job of pre-sowing seed processing. Promote collective seed dressing or seed coating.
Wheat seed dressing includes pest control and disease prevention.
First, control underground pests
The counties surveyed at county stations and monitoring sites in the middle and early September had an average of 1890.4 underground pests per mu, which was higher than last year (1869.5) and calendar year average (1789.3), of which 158.3 were heads, 8.1 higher than last year, more than the previous year. The average is 3.64 high; the number is 1591.4, which is 8.2 points higher than last year and 172.7 higher than the average of the previous year; the rate of golden needles is 140.7, which is 4.6 points higher than last year and 62.1 times lower than the average of the previous year. Underground pests are expected to be moderate to mild to moderate.
Control methods: promote seed coating, treat diseases and pests, drug ratio is 1:50. Uncoated seeds can take the following measures:
1,48% of Loester's emulsifiable concentrate was seeded at a seed weight of 0.3%, and was crushed for 4 hours after mixing.
2, 50% phoxim EC was seeded at 0.2% of the seed weight, and the mixture was boring for 4 hours after mixing.
Second, the prevention and treatment of wheat diseases
The diseases of wheat in our county mainly include powdery mildew, scattered smut, smut smut, rust disease, and virus disease. In recent years, the occurrence of wheat disease has been light, but prevention work can not be ignored. Can be used 50% carbendazim seed weight 0.2% seed dressing, water per 100kg seed 2.5kg, mix and boring after heap 4 to 5 hours. It is recommended that insecticides and disease-preventing agents be used together so as to achieve both disease and disease control effects.
Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (CGMP) - specific phosphodiesterase 5 (PDE5) and an oral drug for the treatment of ED. The physiological mechanism of normal penile erection involves the release of nitric oxide (no) during sexual stimulation. Nitric oxide activates guanylate cyclase in the smooth muscle cells of the corpus cavernosum, which leads to the increase of cGMP level, resulting in the relaxation of the smooth muscle in the corpus cavernosum, the expansion of the cavernous sinus and the inflow of blood. Erectile dysfunction is mainly due to the dysfunction of smooth muscle relaxation of corpus cavernosum. Sildenafil has no direct relaxation effect on human sponges in vitro, but can enhance the effect of nitric oxide by inhibiting the decomposition of cGMP by PDE5 in sponges. Sildenafil can inhibit PDE5, increase cGMP level, relax smooth muscle of corpus cavernosum and let blood flow into corpus cavernosum. Studies have shown that erectile response increases with the increase of dose and plasma concentration, and the efficacy can last for 4 hours (but is weaker than that at 2 hours).
