Cold resistance method of Masui Dauphine fig tree

Abstract

The invention discloses a cold resistance method of a Masui Dauphine fig tree. In the method, a cold resistance plant is grafted on a Masui Dauphine plant by using a grafting method. The method specifically comprises the steps: a branch of a cold-resistant fig 1-1.5 centimeters thick is selected as a scion in spring; the scion is grafted on the trunk of the Masui Dauphine plant; the stem graftingis carried out, and after 15-20 days callus is generated at a grafting port; the sprout of the scion is germinated 30-40 days later; a new branch is generated in the same year, which means that the grafting is successful; the growth increment of the grafted branch can be controlled by modifying,; and the grafted branch becomes a temporary branch. In the invention, the cold resistance method of the Masui Dauphine fig tree has the advantages that: grafting just can be implemented once in the whole life of each tree to completely solve the problem that the Masui Dauphine plant cannot automatically implement dormancy; the cold resistance of the tree can be completely improved; the using amount of inputs such as workload, straw and the like can be greatly reduced; the economic loss of farmers due to low temperature freezing can be avoided; and thereby the technical barriers of scale cultivation of Masui Dauphine plants in the area with low temperature in winter can be solved.

Description

technical field [0001] The invention relates to a cultivation technology of a fig variety, in particular to a cold-resistant method for Masitaufen fig trees. Background technique [0002] The fig variety Masiyi Taofen is widely planted in the south of the Yangtze River Basin in my country. Compared with ordinary figs, the average fruit weight is 80 grams, which is much higher than other varieties; The output can reach 4000 kg, which is a rare high-yield and excellent variety. [0003] However, compared with other varieties, the main defect of this variety is: it is not sensitive to low temperature, and when late autumn comes, other varieties stop growing, a detachment layer is formed at the petiole, the leaves fall off, the cortex begins to thicken, and the sap begins to grow. Backflow, new branches of the year will accelerate lignification, and when they are ready to enter dormancy, the variety is still in the growth period and cannot automatically enter dormancy until mid-...

Problems solved by technology

[0003] However, compared with other varieties, the main defect of this variety is: it is not sensitive to low temperature, and when late autumn comes, other varieties stop growing, a detachment layer is formed at the petiole, the leaves fall off, the cortex begins to thicken, and the sap begins to grow. Backflow, new branches of the year will accelerate lignification, and when they are ready to enter dormancy, the variety is still in the growth period and cannot automatically enter dormancy until mid-December. The cold wave with a temperature difference of more than 10 ℃ in the early winter can cause the variety to suffer from cold damage.

However, this method needs to be re-covered every winter, which is labor-intensive and costly.
