Rate higher does not have the influence of pollination medium, pollen amount not to reduce under indoor conditions, under need to only being brushed before pollination（From
Under concrete conditions in the establishment of a specific crime, crape myrtle pollen activity can only maintain 6-8 hours at 30-32 DEG C）；On the other hand it is mixed can to prevent external source pollen
The possibility of approach, pollen contamination is minimum；
（2）Carries out only continuing two or three for the first time putting the short distance bagging of hour with one with being protected from light polybag and substituting sulfuric acid paper bag
Fixed advantage：Although sulfuric acid paper bag can reduce injury in bagging, when pollinating unpacking since sight is unreachable, to column cap
Injury can not be avoided that and being protected from light polybag has preferably extensibility, is not easy to damage column cap.Experiments have shown that first
It is secondary to use sulfuric acid paper bag bagging, only 8 one-tenth or so of emasculation petal that fully participate in pollination operation, and have part column cap by
Covert harm, and then can be to avoid this partial loss with polybag is protected from light；Secondly, set sulfuric acid paper bag needs careful to heavens, flower
It is time-consuming more, it is also desirable to the time needed for piece petal of emasculation is occupied, it is 2 points luxuriant by single flower if 5 petals cover 1 sulfuric acid paper bag
Clock calculates, to can operate 50 petals in two hours when 7 when 5；Using polybag is protected from light, 4 branches cover 1 polybag,
Two hours only need 3 polybags, bagging time can be ignored, 60 petals of infinite approach so that the efficiency of bagging
It greatly improves.
