Fruit tree virus-free planting technology
1 bag (10g) of 72% agricultural streptomycin, 1 bag (15g) of 72% agricultural streptomycin, 15g of copper sulfate, mix the three, add two or two vinegars to foam and dissolve, and then add 30 jins of spray or root . (Referred to as agricultural streptomycin copper sulfate mixed solution). Add 20 grams of zinc sulfate (zinc fertilizer), 20 grams of boric acid (boron fertilizer) (40 grams of root irrigation) is better. Among them, peach, plum, apricot (plum) and cherry, 15 grams of copper sulfate was used before leaf expansion, and copper sulfate was not used after leaf expansion. Peach, plum, apricot (plum) and cherries use 20 grams of boric acid before spreading leaves and 10 grams after spreading leaves. I. Spraying: 1. Spray 1-2 times from the bud to the flowering stage. Insect control effect is good, do not add insecticides during the flowering period, so as not to kill the media bees and affect pollination and fertilization. The amount of flowers is small and weak. Add 0.5-1 g of gibberellic acid to the mixture to enhance the growth of flowers and pollination and fertilization. Pay attention to vegetables and flowers. 2. In the small, medium and large fruit period, use 1 bag of Chinnon (10 g), 40 g of zinc sulfate, 50 g of lime, add 2 vinegar, stir, add 2-3 jin of water to make chelated zinc calcium Add the thick paste to the No. 3 agricultural streptomycin copper sulfate mixed solution, and spray it once on the small fruit, medium fruit and large fruit to add calcium, significantly prevent cracking, brown rot and rotten fruit, and strengthen Prevention and control of various diseases and insect pests, fruit oil shine. 3. After the leaves are expanded, peach, plum, apricot, plum and cherry do not use copper sulfate in the mixed solution, boric acid (boron fertilizer) is 10 grams, and 2-3 kg of chelated zinc and calcium are added. Spray once in the fruit period. 2. Root irrigation: Add 50 grams of ferrous sulfate to the agricultural streptomycin copper sulfate mixed solution, and irrigate the roots once from flower bud sprout to the flowering stage and the large fruit stage. Too much, too big, too heavy, roots must be irrigated once to prevent fruit drop and nutritional supplements have miraculous effects. To prevent and cure various yellowing diseases of fruit trees, significantly increase chlorophyll, including citrus to control yellow dragon disease, mainly by irrigating roots. The yellow leaves turn light green in 7 days, and change from yellow to dark green in 25 days. Third, it can prevent viruses and viral diseases (repeated crops, premature senescence, dwarfing, flowers and leaves, shrinking leaves, yellow leaves, broken leaves, leaflets, cracked skin, cracked fruits, shrinkage, yellow dragon disease, jujube disease, flower face, rust fruit, Persimmon disease and pox stone disease, etc.), bacterial diseases (root cancer, citrus canker disease, keratosis, etc.), fungal diseases (root rot, tree rot disease, dryness disease, rot disease, scab disease , Anthracnose, melanosis, brown rot, gray mold, black spot, powdery mildew, downy mildew, rust, soot, banana panama disease, etc., comprehensive diseases (flow glue disease, apple mold heart disease) Wait). Amazingly improved fruit yield, quality and increased sugar content. 4. Control various insect pests: In the agricultural streptomycin copper sulfate mixed solution, add 1-2 20% fensulfuron (cypermethrin) (4 ml each), 1-2 bags of 10% imidacloprid (each 10 g bag), spray 30 or 1-3 times with water and spray 1-2 times. In severe insect pests, the amount of medicinal insecticide doubled. Spray once for several months (six months) without insects.
