First, in April management points 1. Cultivation Management (1) Buds, Dingding. Buds grow to 3 cm when the bud buds, shoots grow up to 10 cm can be seen when the first fixed inflorescence, V-shaped shoot length beyond the bottom of the beam drawing 10 to 15 cm, scaffolding shoot length To 8 to 10 leaves, the second set shoot and tied. The first fixed shoot each tree should stay 2 branches in order to prevent wind break, the second fixed if the V-shaped frame cultivation, regardless of line spacing width, the spacing of 15 cm from the tip spacing; if scaffolding cultivation, regardless of fence Shelves or scaffolding surface size, per square meter according to 12 to 14 shoots fixed (large leaf varieties per square meter are pressed
