Wild apricot (Prunus armeniaca var.ansu Maxim) Department of Rosaceae Prunus shrubs, wild jujube (Ziziphus jujuba var.spinosa Hu ex HFChow) Department of Rhamnaceae are important engineering greening tree species in North China, but also with a variety of Ziziphus good use slope greening pioneer species. But, apricot, jujube and more in their natural state or cultivated rootstocks engineering greening projects, the promotion has not been a wide range of applications. The study included five aspects: 1, apricot, jujube seed germination ecological characteristics;, apricot, jujube wilting humidity determination;, apricot, jujube root distribution and root biomass in research; natural apricot, jujube community structure characteristics and components of biological diversity;, apricot, jujube community, stability, designed to explore the the excellent engineering greening process tree, grass seed selection screening principle apricot, jujube in engineering The greening projects promote the application to provide a theoretical basis and technical support. This article through research apricot, jujube seed dormancy characteristics, learned the the wild apricot hard real rate of up to 89.6%, the germination rate of 8.3%; the jujube hard real rate of 93.4%, 23.6% germination rate, apricot, jujube hard seeds were higher, help improve seed germination rate for seed treatment, to help guide the production practice. Concentrated sulfuric acid soaking treatment with hot water soaking axillaris hard real hibernation has good release wild apricot, apricot, jujube hard seeds of concentrated sulfuric acid processing time should be between 20 ~ 30min, soaked in hot water treatment to 100 ℃ hot water treatment works best, it is recommended to extend the time of hard seeds in hot water. Apricot, jujube drought resistance are strong, wild apricot annual transplant seedlings by measuring, apricot biennial transplant seedlings, jujube seedlings annual, the the soil wilting humidity the Vitex annual seedlings were 9.546%, 8.997%, 6.468%, 7.678 %, lower than the Ailanthus hickory, seabuckthorn, Periploca engineering green plants. Apricot, jujube have a strong ability to adapt to the harsh environment, the roots in the soil conditions are good areas, taproot obvious, fewer lateral roots, fibrous roots, vertical distribution; poor soil areas, obviously stout taproot deep into the surface, lateral root many and developed vertical distribution; fibrous root density, mainly distributed in 10-20cm of soil surface, horizontal distribution. The wild apricot shrub communities can not form an absolute advantage Vitex is the dominant species, Lespedeza, Ailanthus its associated tree species; axillaris has an absolute advantage in the shrub community in its associated tree species Lespedeza, Vitex, Ailanthus and mountain elm.
