| 摘要: |
| 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8.0 cm，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3～5 cm，对照区为2～3 cm。 |

| Abstract: |
| This paper describes the technology,principle,experiment of RPA research,sums up the application of RPA.The result shows:It can raise apparently seedling's ability of fighting drought and growth,to dip in the afforestation of thick liquid with RPA,and efficiently prevent the harm of Gansu zokor,rabbit and ox and sheep,the preventive effect to mouse increases 10.2%-13.8%.Dressed and soaked seed handling can strengthen seed vigour,raise emergence rate and sprout rate,make sprout even sprout strong,raise the production potential of soil.RPA can increase the preservation rate,promote lignification,and make the nursery stock over winter,there are 0.5-0.8 stems/m2 in treatment,and the seedling height is 3-5 cm,but 0.07 stems/m2,2-3 cm in CK. |
