First, the young pear garden:
1, continue to grasp the modeling work of young pear trees. A good tree type is the basis for the quality and yield of pear trees. Advocate "dwarf crest happy type", that is, a main pole, 2-3 major branches. This type of tree is particularly suitable for coastal areas and is also an effective measure to prevent typhoons from invading.
2. Focus on the management of fertilizer and water. The management of fertilizer and water is fundamental. To meet and promote the rapid growth of young pear trees with high standards of fertilizer and water conditions, the high-yield skeleton can be quickly formed to achieve the goal of early production. The principle of fertilization: "Fertilizer application", method: Apply fertilizer every 20-30 days. In the early stage, nitrogen fertilizer was used as the main fertilizer. Phosphorus and potassium fertilizers were used. Each plant used 4 kg of compound fertilizer 0.1 kg. When the soil was moist, it was spread around the roots of pear trees.
3, focus on prevention and control of pests and diseases. The current pear diseases mainly include "pear black spot disease" and "black spot disease"; and the pests mainly include "pear hibiscus", "pear pods", "scarabs" and "cattle". "Insecticidal" 3000 times + "Daisheng" 600 times + 0.2-0.3% potassium dihydrogen phosphate can be used for spray control in the evening, spraying once again between 15 and 20 days.
4. Continue to do the drainage work of the pear garden to reduce the groundwater level. Right now in the rainy season, it is necessary to have access to the gutters, drainage is smooth and there is no water accumulation.
Second, put into production orchard:
1. Pay close attention to the tailing of the fruit peeling.
2, increase the expansion of fruit fertilizer: According to the age of the tree, the results of the situation, in early July to increase the expansion of fruit fertilizer, it is best divided into two applications. Each plant applies 45% compound fertilizer 1-1.5 kilograms to promote pear fruit enlargement and achieve superior quality fruit.
3, we must continue to grasp the prevention and treatment of pests and diseases in orchards. The branches and leaves of Liyuan are put into full bloom, and the pests and diseases are more harmful. The use of pesticides is the same as that of young pears, but the spraying of pesticides must be meticulous and thoughtful, and strive to minimize the pest damage and ensure the production of high-quality and pollution-free fruit.
