Embodiment
In order to illustrate the present invention instead of restriction the present invention further, be illustrated below in conjunction with embodiment.
Embodiment one: a kind of method improving shaddock class graft seedling growth efficiency
The present embodiment is for Guanxi small stream honey shaddock, and the method for Ti Gao Guanxi small stream honey shaddock graft seedling growth efficiency is as follows:
1, rootstock seedling is selected: with sour shaddock seedling for rootstock seedling;
2, grafting part and grafting method is selected:
(1) grafting part is selected: utilize the characteristics such as plant growth has apical dominance and shaddock class branch footpath healing ability is strong, the sprouting of fringe bud is fast to carry out grafting, cutting mouth to the distance on top in grafting is that 0 ~ 5.0cm interval arranges gradient test, and the comparative test result of the different grafting part of stock is as shown in table 1.
The comparative test result of the different grafting part of table 1 stock
The comparative test result of the different grafting part of stock shows: although plant growth has apical dominance, when grafting cuts mouth to top distance ﹤ 0.5cm, survival rate and top grade nursery stock occupation rate are only respectively 70% and 65%, not the highest; This is because the easy dehydration in stock cutting back wound is dried up, and cuts and connects more difficult healing, affect survival rate at section place; And after the shaddock rootstock seedling cutting back of suitable grafting, in side, top, cut downwards apart from clip 0.5 ~ 1.5cm place, top and put fringe bud, the method had both overcome to cut in ﹤ 0.5cm cutting back wound and had been connected into the low shortcoming of motility rate, take full advantage of again the feature of plant tool apical dominance, thus survival rate and the ratio shared by top grade nursery stock are the highest, reach 95% and 85% respectively, and Zhou Nianjun can implement grafting; Cut downwards put fringe bud apart from clip ﹥ 1.5cm place, top, the poor growth because not making full use of the apical dominance of plant, is lowered into motility rate, also needs repeatedly to smear stock bud, cut anvil, increase seedling cost.Therefore, best grafting part, should select to cut downwards at distance clip 0.5 ~ 1.5cm place, top to put fringe bud.
