在果树日常管理中,伤口、树皮破损易使病毒病菌侵入而发生病害,雨水淋洗又使伤口发生本质腐烂、坏皮发生生理性病害,导致果树树体长势减弱,果实变小质量差、产量低,果树寿命明显缩短。修剪(锯后)伤口一般边缘长皮的速度一年内仅在一厘米左右,枝条小面积的伤口,一年才能愈合。因此,果树修剪后或树干破皮后的伤口防腐处理,是果树栽培管理中的一项不可忽视的技术措施。应该做到修剪或锯后或树皮受伤后及时防腐、涂抹保护剂处理。果树伤口防腐保护技术简便,只要事先配制好药剂,不分果树品种、树龄、伤口部位、面积大小、不分季节,随时都可进行。方法是:伤口面平(如不平的可用锋利的刀削平)的,用塑料泡沫块或棉球或毛笔沾0.2%的多菌灵或1%的硫酸铜液涂抹伤口消毒,待涂抹的药液干后,再均匀涂抹保护剂,使之形成一层药膜,封严伤口即可。现介绍两种果树伤口保护剂的配制方法: 一、固全蜡。取松香4份,蜂蜡1—2份,牛、羊油(有特殊异味,牲畜闻而避之)1份,放入锅或铝盆内加热溶化后,放入装有冷水的盆内冷却后,取 In the daily management of fruit trees, wounds and bark damage easily lead to virus germs invaded and disease occurs. Rain shower causes the wound to undergo substantial decay and physiological damage to the skin. As a result, the fruit tree body weakens, the fruit becomes smaller, Low yield, significantly shortened fruit tree life. Pruning (sawing) the general edge of the wound long skin speed of only about a centimeter within a year, a small area of ​​the wound branches, a year to heal. Therefore, the pruning of fruit trees or trunk wound after the anti-corrosion treatment is a fruit cultivation management can not be ignored technical measures. Should be done after pruning or sawing or bark injury timely preservation, application of protective agent treatment. Fruit tree wound preservation technology is simple, as long as pre-prepared good medicine, regardless of fruit tree species, age, wound area, size, regardless of the season, at any time. Method is: the wound surface flat (such as uneven sharp knife flat), with plastic foam block or cotton ball or brush stick 0.2% carbendazim or 1% copper sulfate liquid smear wound disinfection to be smeared liquid Dry, then evenly protective agent, to form a layer of membrane, seal the wound can be. Now introduced the preparation of two kinds of fruit tree wounds protective agent: A solid wax. Take 4 parts of rosin, 1 to 2 parts of beeswax, 1 part of beef and mutton (special smell, livestock smell avoidance) into the pot or aluminum basin for heating and melting, ,take
