The horizontal partial application of scraper as deep as xylem, then chooses the 2nd, the 3rd, the 4th or the every 20cm~30cm or so from bottom to top
5 horizontal partial applications of bud, selected sprout arrange in the shape of a spiral at seedling stem position, for cultivating as 3~5 different directions in the future
Skeleton branch;
C, HORMONE TREATMENT:The hormone solution of preparation is applied on the surely dry sprout for staying bud and mesh to hinder with writing brush or cotton swab,
It must sprout when luxuriant piece opening cusp appears and carry out in bud;
D, water and fertilizer management:5~July 5 June applies 30g~50g/ plants of urea (leaded wastewater 46%), July at interval of 15d
Bottom or so, which applies, dredges sour potassium (K2O be 53%), calcium superphosphate (P2O5It it is 12%) 50g/ plants, it is ensured that ground moistening, soil field are held
Water is 70%~80%;
E, branch processing is drawn:By the end of August~September just use fruit tree open-angle device or branch-pulling device, by the branch of step C institutes germination and growth with
Nursery stock center trunk pulls open into 70 °~90 °;
(2) second year is cultivated:Early spring in next year does step (1) nursery stock trunk before sprouting surely again, with swashing for step (1) C
Bud is stayed below element processing clip;
(3) third year cultivates:Step (2) nursery stock passes through biennial length, and treelet trunk growing height reaches 300cm~400cm,
3~4 points of culture is chosen again according to step (1) method staying foster upward spacing 200cm~300cm of 3 skeleton branches or so
Layer skeleton branch.
2. a kind of apocarya tree crown directed cultivation method according to claim 1, it is characterised in that:Step
(1) hormone described in C is 6 benayl aminopurines (6BA) 40mgL-1+ gibberellin (GA3)20mg·L-1+ rape element sterol (BR)
5mg·L-1Aqueous solution.
Advantageous effect
This method apocarya sprout sprout bud point appear when, be using micro new plant growth HORMONE TREATMENT
Can reach desired effect, untreated rudiment, which is suppressed, does not sprout, through mesh wound rudiment under tree nutrient concentrated supply,
