玉米、花生种子包衣是一项新技术,我市自1986年开始试验、示范,在成功的基础上,1988年推广面积已达20多万亩。实践证明,经包衣处理的种子,播后苗期药效持续45天左右,防治效果为蚜虫95%,地下害虫90%,线虫病40%,每亩增产花生20%,玉米15%左右。它不仅防病治虫,促进植株生长发育,而且防止污染,保护益虫,省工省药,是一项经济有效的增产措施,应大力宣传推广。种衣剂4号属剧毒农药,为确保人畜安全,在使用过程中应掌握如下技术要点: 1.包衣的种子要经过精选,确保成实饱满,发芽率高。用种衣剂4号包衣花生仁可按种子量的
Corn, peanut seed coating is a new technology, the city started experimenting and demonstrating in 1986, on the basis of success, in 1988 the promotion area has reached more than 20 million mu. Practice has proved that the seed coating treatment, seedling efficacy after sowing lasting 45 days or so, prevention and control of aphids 95%, 90% of underground pests, nematode 40%, peanut yield increased by 20% per acre, about 15% of corn. It is not only anti-disease pest control, promote plant growth and development, but also to prevent pollution, protect beneficial insects, provincial workers provincial medicine, is a cost-effective stimulation measures should be vigorously promote. Seed coating on the 4th is a highly toxic pesticide, in order to ensure the safety of humans and animals, in the course of the application should have the following technical points: 1. The seeds of the coating to be selected to ensure full and full of fruit, germination rate. Seed coating No. 4 with peanut seeds can be the amount of seed
