| 中文摘要: |
| 壳寡糖（chito-oligosaccharide，COS）被认为具有促进植物生长发育，抑制病毒、细菌、真菌等作用，作为一种新型的多功能生物农药，在植物生长调节及诱导植物抗逆性、抗病性等方面显示了极大的应用潜力。试验研究发现，在晚熟甜橙塔罗科（Tarocco）血橙新系生产中喷施50 mg L-1壳寡糖，单株产量提高13.9％, 可溶性固形物含量增加0.5％，明显增强树势，提高抗旱、抗寒能力，促进生长，提高坐果率、减少裂果，落果，对提高产量和改善品质作用效果明显。 |
| 英文摘要: |
| The chito-oligosaccharide(chito-oligosaccharide，COS) has been known that it can promote the plant growth，constrain virus，bacteria and fungi. As a new biological pesticide, the chito-oligosaccharide has showed the potential for adjusting the plant growth and resisting diseases. The experiment indicated: by the treatments of 50 mg L-1 liquid of 5% chito-oligosaccharide aqua spraying on the leaf surface of late-maturing Tarocco new clone (Citrus sinensis Osbeck cv Tarrocol orange), the average yield and the content of soluble solids can increase by 13.9% and 0.5%, separately .That can enhancement the potential of resistant ability to cold and drought, and increasing fruit-bearing rate , reduce the fruit drop at the physiological fruit drop period and prehavest fruit drop period.It can also increase the yield and improving quality. |
