Problems solved by technology

[0003] Conicum pubescens is a rare and high-quality broad-leaved timber tree species in South China, but there are few artificially cultivated seedlings. At present, there are no seedlings for sale in the seedling market, which greatly restricts the preservation of the germplasm resources of Conicum pubescens.

Abstract

The present invention provides a method for grafting and raising seedlings of hair cones, which comprises the following steps: 1) making a grafting joint tightening device; 2) cutting off the leaves of the hair cone fringes, and trimming the fringes into scions of 3-5 cm; 3) Select the red vertebral seedlings with robust growth and no damage from diseases and insect pests as rootstocks, and cut off the rootstocks at a distance of 20 to 40 cm from the seedling substrate; 4) fix the scions on the rootstocks, and make the grafting positions of the rootstocks and the scions at the grafting interface In the hooping space of the hoop-tightening device, the nut on the hoop-tightening device of the grafting mouth is unscrewed so that the spring pushes the second fixing piece outward to tightly hoop the scion on the rootstock, and the grafting bag is set to wrap the scion. The scion buds germinate, and the hair cone seedlings are obtained. The invention has the characteristics of simple grafting method, high grafting efficiency and the like.

Description

technical field [0001] The invention relates to the field of agricultural implements. More specifically, the present invention relates to a method for grafting and growing seedlings of hair cones. Background technique [0002] Fagaceae is a rare timber tree species of Fagaceae. Its material color is bright red and its material is excellent. It is very suitable for making high-value wooden handicrafts and has a good prospect for artificial timber forest cultivation. Due to illegal harvesting and indiscriminate logging of natural germplasm resources of Cone trichomes, the population number is decreasing day by day, and it is urgent to carry out conservation of Conicia trichomes germplasm resources and gene bank construction. Therefore, there is an urgent need for asexual breeding techniques with high survival rate and easy operation. At present, the asexual seedling cultivation technology of cuttings and bud propagation bud tissue culture is not yet mature, and further scient...
