Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for growing seedlings by cuttings of jujube twigs. Aiming at the situation that the propagation mode of jujube is single and the scale of reproduction is limited, a suitable substrate and a reasonable hormone formula are used for breeding in conjunction with cutting seedlings, which is effective. Solved the problem of small reproduction coefficient and small scale of reproduction of southern jujube

Abstract

The invention discloses a cutting seedling method for choerospondias axillaris twigs. The method comprises the operating steps and flows of seed tree treatment, scion cutting, cutting trimming, auxin treatment, cuttage substrate preparation and treatment, cuttage, post-cuttage management and transplanting. Semi-lignified twigs are taken as scions, so that the rooting rate is increased compared with hard branches; peat soil and perlite are taken substrates, the lower ends of the scions are soaked into auxin before cuttage, and water mist is intermittently sprayed onto the scions after the scions are inserted into a seed bed, so that the moisture can be effectively kept, and rooting of the scions is promoted. Overall, the cuttage method has the advantages of simple steps, convenience in management, short period and high survival rate, and a large quantity of young seedlings can be cultivated within a short time.

Description

technical field [0001] The invention relates to the field of cutting seedling raising of seedlings, in particular to a method for raising seedlings of jujube jujube by cutting cuttings. Background technique [0002] South jujube [Choerospondias axillaries (Roxb.) Burtt et Hill] is a single important multi-purpose native tree species of Anacardiaceae, which is also distributed in India, Indochina Peninsula and Japan besides my country. Because of its strong germination and fast growth, it is widely cultivated in my country and can grow in acidic, neutral and calcareous soils. It is especially suitable for gardens and greening around. Because of its strong resistance to environmental pollution, it is an important tool for preventing urban pollution. It is an excellent tree species for tropical and subtropical ecological public welfare forests or economic forests. Its leaves can be used as fertilizer, wood is widely used, bark and fruit can be used as medicine, fruit is edible,...
