Scarf joint method of Canarium album ReauschRaeusch

Abstract

The invention discloses a scarf joint method of Canarium album ReauschsRaeusch. The method sequentially comprises the following steps of: selecting stock trees, selecting scions, carrying out scarf joint, fixing, managing after scarf joint, and managing the grafted trees which are subjected with to scarf joint for a long term. The scarf joint method of the Canarium album Reaaeuschs has the following advantages of: 1, improving the survival rate, wherein the survival rate of the grafted trees is improved to above 90% from the current 30-50%; 2, realizing dwarfing, wherein the height of the fruit-bearing trees are is descended to below 5 meters from 10 meters; 3, realizing close planting, wherein the plantings at every mu are increased to 30 plants from 12 plants; 4, realizing early bearing, wherein the trial period after planting is decreased to 4 years from 7 years, and the startup time is decreased to 6 years from 10 years; 5, realizing high yield, wherein the yield is improved to 1500 kilograms, but the traditional planting yield per mu is 600 kilograms; and 6, realizing high quality, wherein, comparing with seedling cultivation, a fine variety generation is cultivated through scarf joint with unseparated properties, and fine variety performance can be kept.

Description

technical field [0001] The invention relates to a scarfing method, in particular to an olive tree scarring method. Background technique [0002] olives ( Canarium album Reausch) cultivation traditionally uses olive seeds to sow sexual reproduction. After planting, it takes 7 years for trial production and 10 years for production. The height of the tree is more than 10 meters. The proportion of inferior trees accounts for more than 30%, and the production efficiency is low. Therefore, embedding has become an important technical measure to solve the defects of seed cultivation. Over the past 20 years, olive grafting technology has achieved certain results, but many problems have occurred in the promotion of production. Old and premature decline, less fruit, low yield, no production benefits; split grafting and cutting grafting are adopted for tree height grafting in production, the survival rate is only 30-50%, and the tree body is still tall, with a tree height of about 10...

Problems solved by technology

Therefore, embedding has become an important technical measure to solve the defects of seed cultivation. Over the past 20 years, olive grafting technology has achieved certain results, but many problems have occurred in the promotion of production. Old and premature decline, less fruit, low yield, no production benefits; split grafting and cutting grafting are adopted for tree height grafting in production, the survival rate is only 30-50%, and the tree body is still tall, with a tree height of about 10 meters, which is unfavorable for production Cultivation management has a certain gap from the development direction of fruit tree cultivation technology such as dwarfing, dense planting, early knotting, high yield and high quality
