楚雄州干旱少雨,素有“滇中老旱区”之称,受于旱影响,病、虫、鼠危害十分严重.玉米播种后的全苗、齐苗质量差,缺塘断垄、缺株少苗现象制约着玉米生产的发展.1991年楚雄州种子公司引入种子包衣新技术在玉米生产上试验示范,一次性播足种子,不补种、补苗.实践证明种子包衣具有防虫、防鼠、防病,确保出苗整齐、均匀,玉米生长快,植株旺盛,耐旱性强,绿叶多,抗早衰,提高光合利用效率,促进根系早生
Chuxiong arid and dry, known as the “arid arable land in central Yunnan,” said by the drought, disease, insects, rats very serious harm. After sowing corn seedlings, Qi Mi poor quality, lack of Tong broken ridge, lack of strains Seedlings phenomenon restricts the development of corn production .1991 Chuxiong seed companies introduced new technology in seed coating test demonstration of corn production, one-time sowing seeds, not replanting, make up seedlings. Practice has proved that seed coating with pest control, prevention Rodents, disease prevention, to ensure that the emergence of neat, uniform, fast-growing corn, strong plants, drought-resistant, more green leaves, anti-premature aging, improve photosynthetic efficiency and promote root early health
