Orchard “grass†and “grass coverâ€
The "grass" and "grass cover" in orchards are suitable for orchards with poor soil, low fertility, poor water retention, and large weather and temperature effects. Orchard "sowing grass" is to plant a certain amount of leguminous plants, grasses or pastures between the orchards and between plants. It can also naturally grow grass and manage fertilization, irrigation, etc., and grow grass to 20 At -30 cm, the grass is harvested in stages, sun dried until it is half dry, buried under the canopy, and repeated year after year. The grass method can fertilize the soil, protect the soil, increase the yield and quality of fruit trees, and can also greatly reduce the amount of herbicide used.
Orchard "mulching grass" refers to the harvested crop stalks (wheat stalks, corn stalks, etc.) or leaves, which are directly covered under fruit trees. The amount of grass cover per tree is based on the projected area of ​​the canopy, and the thickness of grass cover is generally 15 -20cm, once "covered" for 2-3 years. It can not only improve soil organic matter, improve soil physical properties, increase tree vigor, and increase the ability of fruit trees to resist cold in winter, but also can effectively control the occurrence of diseases such as sunburn and spider mites.
Dwarf crops growing between fruit trees
By intercropping strawberries and Chinese herbal medicines between young fruit trees or interplanting peanuts, soybeans, mung beans, adzuki beans in summer, and interplanting vegetables with high economic value such as cabbage, carrots, kale, and garlic in autumn and early spring, it will not only improve the economy of orchards. Benefits can also accelerate soil maturation, reduce surface water and fertilizer loss, promote fruit tree growth, and realize the combination of land use and land conservation, with the aim of achieving long-term growth.
Orchard clever use of plant ash
The plant ash is a high-quality potash fertilizer and soil loosening agent, which can improve the drought resistance of fruit trees, make them green and blue, enhance photosynthesis, reduce flower and fruit shedding, promote flower and fruit coloration, and improve fruit quality. At the same time, it is also the nemesis of fruit tree pests and diseases, which can prevent early defoliation and prevent fruit tree diseases such as root rot and downy mildew. For example, using tree ash to prevent root rot in fruit trees is to loosen the soil next to the roots of the fruit trees and gently remove the roots to expose the roots. Use a knife to scrape off the diseased skin on the roots and dry the roots for 2-3 hours before adding fresh grass ash. Sprinkle around the roots, and then cover the soil and bury it. After treatment, root rot is eradicated and new roots are released after 1-2 months. The normal functions of fruit trees in absorbing water and fertilizers are restored.
Application of coal waste fertilizer
According to statistics, the coal waste fertilizer contains 39.5% of water, 0.42% of nitrogen, 0.48% of phosphorus, 1.6% of potassium, 13% of volatile solids, and 24% of organic matter. It also contains other nutrients and has long-lasting fertilizer effect. In the areas where the soil is acidic, the application of coal waste fertilizer has the effect of improving soil structure, reducing soil acidity, increasing soil fertility, loosening the surface of the soil, and promoting the growth and development of fruit trees. If chemical fertilizers are mixed with coal waste, it can also reduce the leaching loss of chemical fertilizers, indirectly increase the fertilizer efficiency and enhance the absorption capacity of roots, and promote fast-growing, high-yield and stable production of fruit trees.
Orchard raising livestock and poultry
Orchards raising livestock and poultry and carrying out reasonable planting and breeding can be complementary and greatly improve the economic efficiency of the fruit farmers. Has been promoted and applied: orchards chicken, pigs, geese, turtles and so on. Taking chicken as an example, chicken manure is a good fertilizer that can increase the fertility of soil in orchards and reduce fertilizer investment. Since chickens like to feed on small insects, they can prey on a large number of pests on the ground and fruit tree stems; as well as the pests and eggs of these pests, so that the orchard pests greatly reduced, while reducing the amount of pesticides. In addition, the orchard has a rich source of food. The chickens can eat a variety of insect live food, but also can eat grass, etc., which can not only save the feed, but also play the role of weeding in the orchard, but also enhance the chicken population and reduce the incidence of disease. In this way, it is beneficial to reduce the content of harmful components of pesticides and fertilizer residues in fruits and chickens.
"Pig (cattle) - marsh - fruit" ecological orchard
The production of biogas slurry and biogas residue from pig manure and the fertilization of fruit trees with biogas slurry and biogas residue can greatly reduce the amount of chemical fertilizers used, change the situation of many fruit fertilizer residues in the past, and greatly improve the quality of the fruit, realizing “pig (cattle)—marsh - If it is a virtuous circle, build an "ecological orchard."
In addition, the use of biogas slurry can also prevent fruit trees pests and diseases. If appropriate amount of biogas slurry is filtered and then clear liquid is sprayed, the control effect on spider mites is about 91%. Irrigation with biogas slurry can effectively prevent root rot of fruit trees.
