一、空气及插壤的温度空气及插壤的温度是影响插条生根的重要外因之一。气温影响到主要的生理过程,例如,呼吸作用,光合作用以及水分交换的强弱等等。插穗对于温度状况的反映决定于植物的生物学特性,插穗枝条的发育时期以及温度和其它环境因子的相互配合等.很多人认为对插穗生根最有利的气温约为二十至三十度;如果插壤的温度稍高于气温,则对插穗生根更有利.因为插穗两端出现的不同的生理活性有利于生根,当插壤温度高于气温时,插穗基部的呼吸作用强度要比梢端高,这就能促进插穗很快地形成根原始体及根系.
First, the temperature of air and plug the air The temperature of the air and the plug is one of the important external factors that affect the rooting of the cuttings. Temperature affects major physiological processes such as respiration, photosynthesis and the strength of the water exchange. Cuttings for temperature conditions reflect the biological characteristics of plants, cutting branches of the growth period and the temperature and other environmental factors with each other, etc. Many people think the most favorable temperature for cutting rooting about twenty to thirty degrees; if The temperature of plunging is slightly higher than the temperature, then it is more favorable to the rooting of the cuttings.Because the different physiological activities at both ends of the cuttings are conducive to rooting, when the plunge temperature is higher than the temperature, the respiration intensity of the cuttings base is higher than the tip , Which can promote cuttings to quickly form root primordia and roots.
