Hong Anzhang seedling growing method by cutting

Abstract

The invention discloses a Hong Anzhang seedling growing method. Before cutting, female parents are disinfected, deinsectization is conducted, strong upper branches are taken as cutting slips. The cutting slips are trimmed into the shape with the length of 6-10 cm and the diameter of 0.3-0.5 cm, the bottoms of the cutting slips are cut flatly, more than half of strong leaves are reserved on the tops, and after soaked for a few seconds for disinfection, the cutting slips are quickly wet with paste prepared from rooting powder. Sticky deep-layer red earth is selected; on a cloudy day or in the morning, the cutting slips are subjected to cutting in a 9*11 non-woven fabric seedling growing bag with cuttage soil; after cutting, the Hong Anzhang cutting slips are disinfected again, an arch plastic-coated steel tube is used for arch making, water-absorption thick non-woven fabric strips are additionally arranged, anti-drop film covers the fabric strips for sealing, a sunshelter is constructedoutside the arch, an overshadowing net with the overshadowing rate of 95% covers the sunshelter, and a monopotassium phosphate solution or a leaf fertilizer which contains bactericide and can promoterooting is sprayed every 10 days. The seedling growing method of cutting propagation is adopted for conducting propagation on Hong Anzhang nursery stocks of the superior type and has the advantagesofquick propagation speed, high germchit purity and high survival rate.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for raising seedlings of Eucalyptus eucalyptus by cuttings. Background technique [0002] Eucalyptus Hong is an evergreen tree species of the genus Cinnamomum lauraceae. It is a new variety of forestry plants discovered and bred in Xuefeng Mountain, Hongjiang City, Hunan Province. Hongeucalyptus camphora is a chemical camphor tree, and its seeds are differentiated and mutated. Cutting seedlings is an effective method for maintaining traits. Eucalyptus eucalyptus leaves are rich in eucalyptol, and the essential oil extracted through cultivation is widely used in medicine, flavors and fragrances, cosmetics and other industries, and has broad market prospects. However, no one has provided an effective cutting method for Eucalyptus eucalyptus at present. In addition, people usually carry out water supply and nutrient operations manually during the cutting cu...

Problems solved by technology

However, no one has provided an effective cutting method for Eucalyptus eucalyptus at present. In addition, people usually carry out water supply and nutrient operations manually during the cutting cultivation process, but manual spraying errors are relatively large, especially when large-scale cutting seedlings are raised. The nutrient and water supply of each seedling cannot be precisely controlled, resulting in a low survival rate of seedlings
