Grape spring tube note these points
First, wipe the bud This work is the key to the quality of the grape. 1. Method: According to the tree vigor, determine the sooner or later. The tree tends to be weak—the result is a branch with a thickness of 0.6 to 1 centimeter. To wipe off buds early (approximate in mid-April), wipe the buds and leave strong buds. The tree vigor is strong—the result is that the thickness of the branches is more than 1 cm, and the buds are to be late (new shoots grow to 10-15 cm), and the strong buds are left to leave the weak buds. 2. Effect: Correct smearing can reduce the size of grapes and increase yield. Second, in addition to sprouting 30 cm above the ground surface, leaving no leaves, to ensure that the lower ventilation and light transmission, to prevent the late white rot and anthrax. Third, take care to avoid nutrient consumption, so that nutrient return, improve the fruit setting rate. 1. Time: 2 to 3 days before flowering (when the flower grows on the tree in the strongest place on the ground), picking it up early will lead to new strips, which will not reach the purpose of nutrient reflux. 2. Size: 4 to 7 leaves above the panicle (picked to normal size leaves). Fourth, oyster spikes conserve nutrition and increase fruit setting rate. 1. Time: Start about 1 week before flowering. 2. Size: 1/4 to 1/5 of the length of the ear. V. Pest Control 1. Clear Garden Medicine: Before the sprouting of the grapes, spray 3 to 5 Baume degrees of lime sulfur or 600 times of cysteamine. 2. The second round of medicine, inflorescence separation period (in early May): To guard against a disease of the two insects, that is, blind stink bug, thrips thrips and cob brown blight. Sprayed propylenzinc zinc + hyperchloromethane salt + imidacloprid or absolute three generations + leaves cool, disease prevention and pest control and zinc supplementation, reduce the occurrence of small particles.
