本文研究了软枣猕猴桃育苗技术及原理。试验证明,利用软枣猕猴桃的绿枝扦插可以培育成苗,该技术适用于生产实践。初花期取材,扦插于烟囱灰基质的比幼果膨大期取材插于沙基质的成苗率高,平均为76.4％,后者为24.9％;枝条类型(营养枝和徒长枝)与生长素(NAA—Na)二因素对成苗率有显著影响,枝条部位(上、中、下)对成苗率无显著影响,100ppm NAA—Na处理的效果超过200ppm的及对照;透光度在50—60％(半遮荫)条件下可以保持育苗生根所需的湿度(90％)和温度(25—28℃);绿枝插条上保留部分叶片有利于冬芽萌发,插条发生不定根的部位是形成层带,不定根突起能突破韧皮部的纤维层,伸到皮层之外;不定根的发生与伤口处形成的愈伤组织无关。
This paper studied the jujube kiwi seedling technology and principles. Tests show that the use of green jujube kiwi cuttings can be nurtured into seedlings, the technology is suitable for production practice. In the early flowering stage, cuttings in the ash matrix of the chimney had a higher percentage of seedlings inserted into the sandy matrix than those of the young fruit, with an average of 76.4% and the latter 24.9%. The types of shoots (vegetative shoots and legumes) and auxins NAA-Na) had a significant effect on the rate of seedling emergence. The shoots (upper, middle and lower) had no significant effect on the rate of seedling emergence, the effect of 100ppm NAA-Na treatment exceeded 200ppm and the control; Under 60% (semi-shading) conditions, the humidity (90%) and temperature (25-28 ℃) required for rooting can be maintained; some leaves are retained on green shoots to promote winter bud germination, and adventitious roots are The formation of zonal bands, adventitious roots can break the phloem fibrous layer, extending beyond the cortex; adventitious roots and wounds formed at the callus has nothing to do.
