In June, the flower buds of Zanthoxylum nitidum began to differentiate, and the fruits entered a period of slow growth. The growth of the roots entered the second peak period. The three important development stages were concentrated in June. Therefore, the good or bad management in June is closely related to the tree growth and results in the coming year. Complementing the fat in June depends on the day, the land, and the trees for appropriate topdressing, which can promote flower bud differentiation and facilitate fruit development. Under irrigation conditions, 0.2 kg of urea, 0.4 kg of superphosphate, and appropriate quantities of potash fertilizer and trace element fertilizers can be applied to each soil in the ditch, and the amount of water should not be too large. The dry land can be supplemented with root fertilizer, and the pepper garden is sprayed with 0.3% urea and 0.3% potassium dihydrogen phosphate solution, and sprayed twice to meet the needs of the growth and development of Zanthoxylum bungeanum on nutrients. Xia Xie Xia Jian mainly regulates the distribution and operation of nutrients and promotes flower bud differentiation and fruit development. The method of summer shearing mainly uses de-emergence, thinning, picking and twisting. Summer cut can improve ventilation and light conditions, increase photosynthetic efficiency, promote flower bud differentiation and fruit growth, and increase yield. Disease prevention and control In June, the important diseases that occurred in pepper were pepper rust and pepper anthrax. Diseases should be mainly controlled by agriculture, supplemented by pharmaceutical control. The pharmaceutical agent was selected based on agricultural control. Pepper rust can be treated with 15% triadimefon 1000 times spray at the beginning of the disease. Pepper anthracnose can be used in the early stages of disease use 50% Tuzi special 700 times spray control. The pests of Zanthoxylum bungeanum are mainly narrow pepper worms. This worm is currently the most harmful pest to Zanthoxylum bungeanum, and we must pay attention to prevention and treatment at one time. June was the worst period of damage to Giardia. Control measures: 1 Spray 100 times of omethoate to kill the newly hatched larvae. 2 Use a sharp knife to scrape the fluidized area together with the rotten skin, scrape it to the edge of the good skin, and then apply a protective agent. 3 Apply 30-50 times omethoate to the trunk glue repeatedly to receive obvious control effect.
