河北农业技术师范学院(地址昌黎)张培玉等同志,于1985—1987年进行了山楂苗木不同药剂浸根试验。试验结果看出,在山楂定植前用10ppm萘乙酸浸根12小时,效果相当理想。①促进了山楂苗木发根多,新根重(克)比对照(浸清水)重59. 5％,根数比对照多53. 6％;②提高了成活率,成活率比对照提高10—15％;③幼树生长健旺,萌芽率比对照提高29—83％,新梢生长量比对照提高20—34厘米,叶片净光合强度比对照提高91. 14％;④抗性增强,如干旱蔫焉和缺铁黄化分别比对照减
Hebei Agricultural and Technical Teachers College (Address Changli) Zhang Peiyu and other comrades, in 1985-1987 hawthorn seedlings of different agents dip root test. The test results show that, before the hawthorn colonization with 10ppm naphthalene acetate root immersion for 12 hours, the effect is quite satisfactory. ① promoted hawthorn seedling hair root more, new root weight (g) than the control (immersion water) weight 59.5%, 53.6% more roots than the control; ② increased survival rate, survival rate increased 10- 15%; young seedlings grow vigorously, germination rate increased by 29-83% compared with the control, shoot growth increased 20-34 cm than the control, leaf net photosynthetic intensity increased 91.14% over the control; ④ increased resistance, such as drought Yan Yan and iron deficiency were reduced compared with the control
