枣树开甲,即对枣树进行环状扒皮。枣树开甲当年可增产30%～50%,果实品质明显提高,好果率约提高5%。1.开甲时间枣树花量多,花期长,在日平均温度达18～20℃时开花,20℃以上进入盛花期。枣树花期在5～6月份,开甲时间从始花至盛花期均可,但以全树花开量达30%左右时开甲增产效果最好。开甲过早效果差;开甲过晚,座果时间推迟,果实生长期缩短,果实品质降低。2.开甲方法在枣树开甲适期,选无风晴天进行。初次开甲的枣树,在距地面30厘米处选主干光滑无刺处开始,先用刮刀去掉一圈老树皮,宽约1.5厘米,露出粉红色的皮层,然后用笔绕树干画两条平行线,两线间距0.3～0.6厘米,用锋利快刀沿上线横切一圈,切断韧皮部深达木质部,再用相同方法沿下线横切一刀,将两刀之间的韧皮轻轻扒掉。为防止甲口积水腐烂感病菌,甲口下沿茬口应削成斜面形;为促进
Jujube open armor, that is, the jujube ring ring. Jujube tree can be increased when the rate of 30% to 50%, fruit quality improved significantly, good fruit rate increased by about 5%. 1 open a time jujube flowering, flowering long, the average daily temperature of 18 ~ 20 ℃ when flowering, 20 ℃ or more into full bloom. Jujube flowering in May to June, open a time from the beginning of flowering flowers can be, but the full flowering rate of about 30% of the best when the yield increase. Premature opening effect is poor; open too late, fruit set postponed, the fruit growth period shortened, fruit quality reduced. 2. A method of opening a jujube Kai period, the election windy sunny day. The first jujube tree to open, at a distance of 30 centimeters from the ground to choose the main smooth no barbed began, first with a knife to remove the ring of old bark, width 1.5 cm, exposing the pink cortex, and then use the pen around the trunk to draw two Parallel lines, the distance between the two lines 0.3 ~ 0.6 cm, with sharp sharp knife along the line across the circle, cut the phloem deep xylem, and then along the line with a knife across the line, the bast gently between the knife off . In order to prevent decay of a sense of rot bacteria A, I stab under the mouth should be cut into a bevel-shaped; to promote
