为了改造产量低、品质差的茶园,可采取以原有的老茶树作砧木,选用适合本地的无性系良种作接穗,通过嫁接,将原有品种混杂的茶园改造成性状一致、丰产优质的无性系良种茶园,其优点是建园周期短,成园快,而且能利用老品种的适应性提高抗逆能力和丰产性能。 1、嫁接时期和接穗的培养茶树嫁接一般在5～10月进行,以6～7月成活率最高。接穗的培养是:通过深修剪促发健壮的枝条,待茎变红棕色(半木质化)后即可作接穗用。采穗前7～10天打顶,并用0.5％的尿素加敌敌畏1000倍液喷雾一次,使腋芽饱满充实。
In order to transform the low yield, poor quality of the tea garden, the old tea tree can be taken as the rootstock, the selection of the local clonal elite as a scion, through grafting, the original varieties mixed tea into the same traits, high yield of asexual Department of good kinds of tea plantations, its advantage is to build a garden cycle is short, into a garden fast, and can use the adaptability of older varieties to improve resilience and high yield performance. 1, grafting and scion cultivation Tea tree grafting generally carried out in 5 to 10 months to 6 to July the highest survival rate. Scion cultivation is: through deep pruning promote healthy branches, until the stem becomes reddish brown (semi-lignified) can be used for scion. Topping 7 to 10 days before heading, and spray with 0.5% urea and 1000 times dichlorvos once, so full of axillary bud full.
