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 invention provides a grafting seedling-raising method of ford chinkapin. The method includes the following steps of 1, a grafting joint tightening device is made; 2, leaves of ford chinkapin spikes are cut off, and the spikes are pruned into scions of 3-5 cm; 3, robust seedlings free of disease and pest damage ae selected as stocks, and the stocks are cut off at the portions 20-40 cm away from a seedling cultivation substrate; 4, the scions are fixed onto the stocks, the grafting positions of the stocks and scions are located in a tightening space of the grafting joint tightening device, nuts on the grafting joint tightening device are screwed out so that springs can push a second fixation piece outwards so as to tighten the scions on the stocks, grafting sleeve bags are used for wrapping the scions, and when scion buds germinate, and the ford chinkapin nursery stocks are obtained. The method has the advantages that the grafting method is simple and the grafting efficiency is high.

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...
