阐述了多效抗旱驱鼠剂(RPA)研制的技术路线、组方原理、试验研究结果等。用RPA进行常规蘸浆造林,能显著提高苗木的抗旱能力和生长量,可有效预防甘肃鼢鼠、草兔和牛羊的危害,定植2年后油松的高生长比对照提高8.0cm,对鼠类的综合预防效果提高10.2%～13.8%。用RPA进行拌种和浸种处理,可以增强种子活力,提高出苗率和成苗率,使苗齐苗壮,提高土壤的生产潜力。RPA在苗圃育苗或飞播造林中应用,能够提高成苗率,促进苗木木质化程度,使苗木安全越冬,促进苗木根系的生长,起到以根提水,以水促长的作用,处理区油松幼苗保存量达0.5～0.8株/m2,对照区仅为0.07株/m2,处理区油松苗木平均高3～5cm,对照区为2～3cm。
The technical route of development of multi-effect drought-resistant rat repellent (RPA), principle of group prescription and experimental research results are described. RPA for conventional dip in the pulp afforestation, can significantly improve seedling drought tolerance and growth, which can effectively prevent the harm of zokors, rabbits and cattle and sheep in Gansu, two years after planting Pinus tabulaeformis height increased 8.0cm, The comprehensive preventive effect of mice increased by 10.2% ~ 13.8%. With RPA seed dressing and soaking seed treatment, can enhance the seed vitality, increase the rate of emergence and seedling, seedlings Qi Zhuang Zhuang, improve the potential of soil production. RPA nursery nursery or aerial seeding afforestation applications, can increase the rate of seedlings, promote the degree of lignification of seedlings, so that seedlings safe winter, and promote the growth of nursery stock root, play a root to raise water, water to promote the role of processing oil The seedlings of Pinus densiflora seedlings were 0.5-0.8 plant / m2 in the control area and only 0.07 plant / m2 in the control area. The average height of Pinus tabulaeformis seedlings in the treatment area was 3 ~ 5 cm and the control area was 2 ~ 3 cm.
