The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.
结果表明:不同无性系的萌条数量有显著差异,高的达14.8条/月,低的5.5条/月,平均9.1条/月,从0.05~2.00 mg/L,随着IBA浓度的提离,生根率、根条数、总根长等生根指标均呈现有规律的变化;综合考虑各种生根指标,以IBA0.05 mg/L为最佳生根激素处理,扦插介质对柚木插穗生根有显著的影响,以泥炭土+黄心土按1:1混合为最佳扦插介质;不同无性系的扦插成活率不同,从56.7%至90.0%,变动幅度大,随扦插季节变化,生根率和成活率均呈现有规律的变化,5~6月份的生根率中等,7~8月最高,9~10月份迅速下降,成活率随季节的变化也是两头低、中间高,6~8月的成活率最高,大于93%。

On the basis of analyzing the thermodynamic properties and cycle performance of pure refrigerants, the paper optimizes their concentration while screening NARMs used in wide variable-temperature heat source. The practical applications of NARMs, such as R22/R123, R123/R125 etc., are studied in geothermal heat pump, seawater heat pump, air dehumidification system and dual-evaporator domestic refrigerator. The results show that the NARMs can match the limitation of a pinch point at the air-side exit of heat exchanger, reduce the unreasonable heat transfer temperature difference, and improve the COP of system. The above conclusion is proved by measuring the cycle performance of R12, MP39 and R11/R22 in a two-evaporator experimental system.
