Orchard ecological management technology
Orchard grass is an advanced, practical and efficient soil management method that can control the harmful effects of poor weeds on fruit trees and orchard soils. It is a time-saving and labor-saving management technique for orchard management. The benefits of orchard grass (1) It can avoid deep turn in successive years. The agglomerate structure of the soil will not be destroyed, and the roots of the fruit trees will not be damaged by deep turning. (2) Prevent soil and nutrient loss caused by soil erosion. (3) It can be watered or not watered to avoid soil compaction. (4) The surface soil nutrients will be absorbed and utilized by the shallow root grass, and finally returned to the soil to replenish the fruit tree nutrition. (5) It can increase soil organic matter content and improve soil physical and chemical properties. (6) It can reduce some pests and diseases. Due to the grass, some of the pests are concentrated in the grass, and the tree does not harm the tree. (7) Adjust the ecological environment and improve the microclimate of the orchard. The grassy orchard in the garden in summer and autumn is 2-3 degrees lower than the temperature of the non-grass orchard, avoiding the sunburn caused by high temperature. Orchard grass way In the mature orchard with deep, fertile or deep roots, the whole garden can be used. For shallow or thin orchards, the inter-row grass method or the inter-plant grass method can be used. Generally, the young orchard adopts the whole garden grass, and the adult orchard adopts the inter-row and inter-plant strip-like grass method. Orchard grass selection (1) The height of the grass should be relatively low and the coverage rate is high. (2) The root system of grass should be dominated by fibrous roots, without coarse main roots or main roots and not deeply distributed in the soil. (3) There are no common pests and diseases with fruit trees, and they can inhabit natural enemies of fruit trees and pests. (4) The time during which the ground cover is long and vigorously grows is long. (5) Shading resistance, trampling, simple breeding, management and labor saving, and easy mechanical operation. (6) Grass species generally choose clover, grass carp, sand sorghum, small crown flower, meadow bluegrass, Baimai root and so on. Orchard grass notes 1. Casting at the right time. Do not castrate after the grass is planted, and start to castrate when the grass grows strong enough. Castration should master the height of stubble, legumes should leave 1-2 branches, generally 15 cm high, gramineae should pay attention to the leaves, generally about 10 cm high, after cutting, the grass will be covered on the tree plate. 2, castration 3-5 times a year, after 5-7 years, the grass gradually aging, need to be updated in time to turn the grass into the ground, re-sow after 1-2 years of leisure. 3. Rational fertilization. The first three years of grass production should increase the amount of fertilizer applied to supply the growth of grass and fruit trees. In addition to applying the base fertilizer before planting, it is also necessary to apply nitrogen-rich organic fertilizer at the seedling stage to promote the growth of the grass seedlings, and the fertilization can be appropriately reduced in the following years. 4. Reasonable watering. Orchard grass is prone to water and grass trees, and fruit trees must increase the number of cuttings and irrigation. Water should be poured in time when drought is lacking.

They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
