Rapid rooting method for olive cutting slips

Abstract

The invention discloses a rapid rooting method for olive cutting slips. A composite rooting solution is used for soaking cutting slips in the cutting process, and materials of gamma-polyglutamic acid,dopamine hydrochloride and nano chitosan and the like are added into the rooting solution on the basis of taking indoleacetic acid as an exogenous hormone growth regulator, so that high-activity gel-like thin films can be formed at the roots of the cutting slips, the absorption efficiency of the roots to the nutrient elements in the soil is improved, the cell tissue differentiation is promoted, and the sprouting of the root system is accelerated. In addition, the effective components in the rooting solution are fixed to the root part, so that the long-term promotion effects of preserving moisture and resisting bacteria are achieved, the adaptability of the roots of the cutting slips in the soil is improved, rich nutrients can be improved, and the cutting survival rate can be notably improved. The rooting rate of the olive cutting slips soaked by the rooting solution can be up to 85%, and the seedling breeding period at a same condition is averagely shortened by 2-3 months.

Description

technical field [0001] The invention relates to a cutting plant cultivation method, in particular to a method for rapid rooting of olive cuttings. Background technique [0002] Olive oil with high economic value is a world-renowned woody oil plant and fruit tree species. It is rich in high-quality edible vegetable oil-olive oil. It is a famous subtropical fruit tree and an important economic forest tree. It is mainly distributed in Mediterranean countries, Greece, Italy, Tunisia and Spain. Concentrated origin. Since the 1960s, my country began to introduce olives in batches and plant them experimentally, and achieved good economic and social benefits. The initial introduction areas were concentrated in Longnan, Shaanxi, Sichuan Basin, Yunnan and other places, and there were few introductions in other inland areas. At present, with the advancement of cultivation technology, Guangdong, Guangxi, Jiangsu and Zhejiang, and the Huaihe River Basin also have the climate and geograph...

"IBA, NAA, ABT 1# The article “A Preliminary Report on the Effects on the Rooting Rate of Olive Cuttings” introduced the relationship between three exogenous hormones and the rooting rate. The results showed that there was a significant positive correlation between the surface growth hormone concentration and the rooting rate, and the IBA treatment had the best effect. However, these single hormones The highest rooting rate of cuttings after treatment is only 73%, which is still difficult to meet the needs of large-scale cutting propagation
