Embodiment 1:
In this enforcement, a kind of method of red heart Fructus Citri grandiss secondary outcome, in non-florescence, prune the branch and leaf of red heart grapefruit.Pruning Away Branches
The period of leaf, the branch and leaf of pruning included disconnected branch, deadwood, weak branch, disease and the winter tip for November to before bloom；If grapefruit grows
Situation is luxuriant, takes the trim mode that density is pruned, if grapefruit growth growing way is weak, takes the mode of cutting back pruning；Pruned
Cheng Zhong, on every tree body branch, the form that veteran branch and young sprout alternate retains.
Using aforesaid way, cut off amputation, deadwood, weak branch etc. to will not result branch, grapefruit root absorption can be made
Nutrient be all conveyed to the pre- branch yielded positive results staying, to prepare for yielding positive results of later stage, because Fructus Citri grandiss are general
It is grown on enriching shoot, and the blooming and connect the efficiency of fruit and be all directly proportional with the nutrient being absorbed of grapefruit fruit, absorbing more
In the case of many nutrients, the nutrient of absorption is more, and flowering rate and fruit-setting rate all can greatly improve, and the quality of its fruit is also
Higher.
In the present embodiment, for the grapefruit of different times, the mode that it is pruned is different, and difference is as follows: when pruning seedling,
Because its apical dominance is more serious, therefore take pruning trunk at 30 40cm in graft union, and stay 23 on every trunk
Root is secondary dry, so that late growing stage；Prune bearing-age tree when, leave more leaveves Fruit branch and choose leaveves growth more uniformly set
Branch, prune away that the trunk branch of excessive growth of vertical growth, the sick branch encroached on by disease pest, trunk under apical dominance effect wither is withered
Branch, and the excessively dense fine still weaker numerical value of its own trunk of leaveves, so that grapefruit yields positive results；Prune old and feeble branch
When, remove in time the average branch and leaf of growth on old and feeble branch and the weak branch and leaf of growing way, leave growth branch and leaf the strongest, so that
Yield positive results.
