A method for the cutting propagation of Sacha Sacha inchi

Abstract

The invention discloses a method for cutting and propagating plukenetia huayllabambana, and relates to the technical field of rapid and efficient propagation of special plant resources. The method comprises the steps that annual branches of the plukenetia huallabambana serve as cutting woods, and semi-lignified stems with the length ranging from 10 cm to 15 cm are selected as cuttings; a root sun rooting aqueous solution with the concentration of 500 pp is used for soaking for 10 s, or the bases of the cuttings are placed in the rooting powder, with the concentration of 1000 pp, prepared in advance for sticking, the height for sticking the powder is about 2 cm, cutting is conducted, or a liquid-moving machine is used for injecting 10-microliter ABT solutions with the concentration of 1000 pp into the interior of a notch in the lower portion of each cutting, and cutting is conducted; cutting media comprise 50% of clean river sand, 30% of yellow soil and 20% of peat soil; the media are filled into non-woven fabric container bags. During the early root period, the container bags are covered with films and shading nets with over 90% of shading rate, after the seedlings are exercised for 60 days, over two pairs of needles grow, the height is over 30 cm, and the seedlings can be moved from a nursery to a big field for planting. According to the cutting and propagating plukenetia huayllabambana, the survival rate of the cutting seedlings is over 95%, and the rate of outplanting is over 90%.

Description

technical field [0001] The invention relates to the technical field of rapid and efficient propagation of special plant resources, in particular to a method for cutting and propagating sacha sacha inchi. Background technique [0002] Sacha Sacha belongs to the perennial woody vines of the Euphorbia family (Plukenetia). Currently, 40 species have been discovered, and 5 species have been planted on a large scale. Sacha Inchi originally grew in the tropical rainforest of the Andes in South America. It is called SachaInchi in the Inca language. It has been used by local indigenous people in South America for more than 3,000 years. Sacha Inchi is planted in the same year, and it can bear fruit in that year. It will enter the peak production period in 2-3 years, and its peak production period can reach about 10 years. [0003] The oil content of Sacha Inchi seeds is 30%-60%, rich in oil, protein, amino acid, and various vitamins and tocopherols. Sacha sachacha seed oil is mainly...

Problems solved by technology

During the trial planting in the south of our country, it could not withstand the high temperature in summer, and there was a danger of low temperature in winter, so it was difficult to grow well.

The germination rate of Sacha Inchi seeds is low, generally about 40%. At the same time, it is very difficult and expensive to import Sacha Inchi seeds
