Water management: Nitrogen fertilizers are used as base fertilizers in the first and second years after the establishment of young trees to promote the formation of tree crowns. In combination with top-dressing fertilizers during the growth period, the nutrients of the tree are enhanced, and flower bud formation and flowering and fruiting are promoted. The results of lemon tree fertilization focus on the fruit expansion period and the autumn shoots. Root irrigation with root fertilizer + micro-fertilizer can induce the absorption and utilization of various trace elements in the soil by the root system, so as to increase the positive energy of fruit development and optimize the fruit quality. And combined with the growth situation often topdressing urea and phosphorus and potassium fertilizers. Topdressing uses thin fertilizers to prevent loss. When lemons do not tolerate drought, they must be sprayed or irrigated in time.
Weeding and weeding: We must cultivate the soil before the drought. The weeds under the canopy should be removed to keep the soil loose. It is necessary to spray new high fat film, reduce water evaporation, prevent water and soil loss, and prevent pests from invading.
Pruning pruning: Lemon saplings thrive, and tend to have leggy shoots on bent branches and branches, disturbing the tree. When pruning, light should not be heavy, leaves more leaves, and can penetrate a small amount of sunlight inside the canopy. The anti-corrosion film was applied on the wounds of the knife and scissors to protect the growth of wound healing tissue, prevent infection with rot, prevent soil and rain pollution, prevent freezing, and prevent chapped wounds. Strong pedicle fruit; in the bud stage, young fruit stage and fruit enlargement period, spraying strong fruit turmeric, can increase fruit pedicle, increase the amount of nutrient delivery, prevent falling flowers, improve pollination ability, increase fruit setting rate, speed up the expansion Speed, ensure fruit quality and high yield. The annual size of the tree bearing fruit causes the tree to bear an imbalance, affecting both the equilibrium income and the orchard's tree health. In the annual flower bud differentiation period, a blunt blade is used to cut deep into the xylem at the smooth part of the trunk. The kerf is 1.5 mm wide. After 1 hour, use a brush to apply a 1 cm wide Kawang No. 2 cream on the kerf, and apply it back and forth. , so that the drug into the cut slit. High temperature and rainy weather can be used 1-2 times. Increase the rate of fruit set, madness, completely balance the size of the year.
