Citrus trees are evergreen fruit trees. They have a long growing period and many types of diseases and insect pests. The number of sprayings is large throughout the year, which may lead to increased drug resistance, reduced natural enemies, and drastic increase in the cost of drugs and pesticide residues. Winter is an important season for controlling citrus pests and diseases. It attaches great importance to prevention and control of winter diseases and pests of citrus trees. The control effect is good, the cost of pesticides is reduced, and fruit quality and benefits can be significantly improved.
In the period from November to the spring of the second year after fruit picking, the citrus trees enter the dormancy period in February. During this period, the citrus and pests all enter dormancy stage, the tree resistance is improved, and the resistance to diseases and insect pests is reduced. Through a variety of control methods and increased drug concentration, the prevention and treatment are improved. As a result, a large number of overwintering diseases and insect pests are reduced, which has a multiplier effect for pest control in the following year.
Citrus tree pests and diseases in winter are mainly controlled by species such as citrus aphids, longhorn beetles, scale insects, canker diseases, and soot diseases. At the same time, the focus of prevention and control should be based on the occurrence of pests in the local production season.
Integrated control methods:
1. Pruning Qingyuan: Combining pruning in winter, cutting off the branches and leaves of diseases and insects, focusing on the eradication of diseased leaves, dead branches and residual fruits of scale beetles, stem beetles, giardia, canker and soot; comprehensive eradication of weeds And the nearby host plants, thoroughly removing lichens, moss and dried piles; excavating the diseased plants of Huanglong, removing or sawing dead trees or branches damaged by Tianniu, resinous diseases, etc.; removing the wintering swallowtail butterfly, leaf roller moth, Codling moth and other insects, brushing off the overwintering moss on the branches. Pruning the branches, leaves, and grass of the Qingyuan Garden must be burned centrally to eliminate overwintering pests and overwintering sites.
2. Fertilize the soil: in the autumn and winter before the budding, with dry fire soil, pond mud, river mud, mud, turf mud and other fertile soil, cultivated around the tree plate, thickness 2-4 cm, 15 per mu. -20 tons. Autumn and winter soil, there is fertilizer, drought and water, improve soil permeability, promote root growth, restore the tree vigor. At the same time, there are also functions such as increasing pest resistance, removing insects, eliminating grass and preventing cold.
3. Whole Garden Deep Turning: Through the deep turning of the whole garden, it is possible to kill some larvae and mites in the soil such as winter buds, larvae, or big fruit fly, and accelerate the decay of diseased tissue debris. After the garden is cleared in winter each year, deep-turning is performed with the application of organic fertilizer. Deeply turning 20-30 cm around the crown, cutting off a few old roots, promoting new roots, and loosening the mature soil. For the red and yellow soils with soil acidity, 50-100 kg of lime are applied to the entire soil before deep plowing to neutralize the pH value and increase the calcium nutrient content in the soil, effectively controlling the occurrence of physiological fluidic gum disease.
4. Orchard anti-freeze: Use lime to add clay or use cement to seal the trunk cracks, or Tianniu, Giardinus boring. Before the frost, the trunk was wrapped around the grass, the tree tray was used for soil cultivation, and the trunk was brushed white to prevent frost damage and resin disease and other diseases.
5. Treatment of deficiency syndromes: According to the diagnosis of soil nutrients and observations in orchards around the country, the citrus orchards in the southern red-yellow loam often produce nutrient elements such as calcium deficiency, magnesium, and trace elements such as zinc and boron. Applying magnesium sulfate, zinc sulfate, and borax in combination with fertilization in winter, combined with deep application of lime to increase calcium, can effectively prevent the above-mentioned deficiency diseases and increase fruit yield and quality.
