(3) plant management: after flower thinning terminates, tree body executes the carbamide of 0.1～0.2kg/ strain and the potassium sulfate of 0.2～0.3kg/ strain, to promote Growth status, in order to the nutrition supplying flower development having abundance；
(4) thinning and jacketing: the fruit to flower late, mid-March without freeze injury after carry out fruit thinning in time, every fringe stays 2～3 fruits, then sprays 80% raw greatly 2500 times of liquid of 1000 times of liquid+10% imidacloprids and carries out insect protected, and medicinal liquid is done in latter 5 days and carried out bagging with double-ply bag black in outer Huang.
Said method only relates to the florescence in Folium Eriobotryae cultivation and fruit phase part management process, Folium Eriobotryae management in other in period, such as waters, fertilising etc., conventionally carries out.
The present invention is by removing in Folium Eriobotryae fringe the flower early opened, and makes tardy in spica to educate alabastrum not because Folium Eriobotryae early stage spends setting to degenerate, so promotes the florescence elongation of whole Honoka.Being that the spica of Folium Eriobotryae generally has 80 flowers, big has 150 flowers according to principle, after the flower early opened is beared fruit, for ensureing nutrition supplying fruit development, the flower opened late is often degenerated and is come off, 5～6 fruits of such a spica only remaining setting.These fruits are concentrated due to nutrition, grow very fast, enter December and run into low temperature, and these fruits are just freezed to death substantially because of frost resistance difference.Therefore, because of Folium Eriobotryae headdress flower freeze to death full tree three/once yield without.If spending first thin going by what early open, not allowing it bear fruit, the tardy alabastrum educated would not be degenerated but continued development becomes flower, so can make Folium Eriobotryae morning spica flowering delay to December even January, the probability that Flos Eriobotryae and young fruit avoid freeze injury can be made to be greatly increased, it is ensured that the high yield of Folium Eriobotryae and stable yields.
