保护果树伤口可以减少病虫,促进生长,延长寿命,增加产量和提高品质。但目前多数果园对这一问题不够重视,造成无形的损失。现介绍两种果树伤口保护剂,供试用。六合一保护剂 (一)材料:1.酚醛清漆250克(中性,起防水、防腐、抗旱、抗寒、抗高温作用);2.敌百虫2克(弱酸性、杀虫剂);3.松香120克(中性、起封闭、保水、防菌类入侵);4.栋素120克(植物杀虫杀菌剂);5.硫磺3克(杀菌、杀螨);6.硫酸铜5克(杀菌)。 Protecting fruit trees can reduce pests and diseases, promote growth, prolong life, increase yield and improve quality. However, at present, most orchards pay insufficient attention to this issue, causing invisible losses. Now introduced two kinds of fruit tree wound protectant for trial use. (1) Material: 1. Novolak 250 grams (neutral, water, corrosion, drought, cold, high temperature effect); 2 trichlorfon 2 grams (weak acid, insecticide); 3. Rosin 120 grams (neutral, from the closure, water, anti-bacterial invasion); 4. Dong Su 120 grams (plant insecticide fungicides); 5 sulfur 3 grams (bactericidal, acaricidal); 6 copper sulfate 5 grams (sterilization).
