Winter date tree dormant period planting
One, base fertilizer
Shiji Fei, high ground temperature, high soil moisture, fast decomposition of fertilizers, is conducive to root absorption. The method of furrowing can be adopted, and 25-50 kilograms of soil-fertilizer can be applied to each tree. When the soil-fertilizer is applied, 2 kilograms of superphosphate can be added to each tree.
Second, white
10 parts of quicklime, 1 part of salt, 50 parts of water and 5 parts of lime sulfur can be mixed and applied to the trunk.
Third, build a garden
1. The selected winter jujube tree in the garden is a perennial fruit tree with shallow root and high light intensity. The result is early and has long life span. There is no strict requirement for the soil, drought resistance, waterlogging resistance and salt and alkali resistance can be grown in the soil with a pH of 5.5-8.5. . However, for the newly-built garden, the growth and development needs of the tree should be met as much as possible. Therefore, the plot should be selected as a plot with flat terrain, sufficient light, fertile soil, good drainage and irrigation, and no pollution.
2, planting time autumn planting seedlings after deciduous soil before freezing is appropriate.
3. Planting Density There are planting lines commonly used in the production of 23 meters, 34 meters, and 37 meters. According to the characteristics of winter jujube hi light, the principles of rational land use are also available. The two kinds of density of 23 meters and 34 meters are ideal.
IV. Planting methods
Generally single row planting, multi-use rectangular, spacing is greater than the distance between the rows, the line to the north and south is appropriate.
V. Planting techniques
1. Seedling selection and treatment Jiandongzao dense planting gardens should be selected to have a height of 1.2 meters or more, a dry diameter of 1 cm or more, a complete root system, pure breeds, good healing of grafted parts, and strong disease-free seedlings. Seedlings planted with the best seedlings planted, long-distance transport from the field of seedlings soaked with water for 10-20 hours before planting the wound roots for renovation. To increase the survival rate, rooting powder can be used for spraying. Specific practice: Dissolve rooting powder No. 3 with a small amount of alcohol, then spray 10-25 kg per gram of water, and cover it with a wet straw mat for 2 hours before planting.
2, planting points to dig depth and width of each 0.8-1 m of the planting point, the topsoil to be separated from the new soil, each planting point Shennong 25 kg and topsoil mix and fill in the hole, with the fill, with the mention of seedlings With practicality. The depth of planting is such that the roots and necks of the seedlings are slightly higher than the ground. After irrigation and sinking, the roots and necks are level with the ground plane.
Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. 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.
