Two hands: Pruning must be in order. Generally, the messy branches are removed to form a rough frame, and then the backbone branches and the resulting mother branches are pruned from top to bottom or from bottom to top. When trimming, pay attention to the principle of "long first, short first, more first, then less". This is mainly for fruiting mother branches. The wounds caused by pruning should be coated with a callus anticorrosive film in time to protect the growth of wound healing tissues from infection of the wound. After pruning, the resulting female branches and backbone branches should be bound. The method of lashing should be based on the principles of flat tie of long branches, oblique tie of middle branches, and non-binding of short branches.
Three inspections: first check the pruning of the backbone branches, such as the angle and the occupation rate of the shelf surface. Then check the pruning of the mother branch at each result site, including the cutting length, the position and direction of the branch group.
Four cooperations: Combine the above four steps and apply hole punching technology to apply "Promoting Kao No. 1" to make the fruit tree bloom early next year, more flowers, no flowers, and strong fruits. Use a conical needle ring to perforate two rows of holes around the tree or the lower part of the main branch with a distance of 10 cm, a distance of 2 cm, and a hole diameter of 3 mm. Use a hair brush to press the hole ring brush to promote Kao cream.

Hematology analyzer is also called clinical blood cell analyzer, blood cell analyzer, blood cell analyzer, blood cell counter. The blood analyzer not only improves the accuracy of the experimental results, but also provides many experimental indicators, which play an important role in the diagnosis and differential diagnosis of diseases. Hematology analyzer is one of the most widely used instruments in hospital clinical testing.
Test items
Blood cell test refers to routine blood test, which is manual operation and counting under the microscope at first. It includes red blood cell, hemoglobin, white blood cell count and its classification, platelet count, etc. There are more than 20 items.
clinical significance
1. The blood analyzer is mainly used to detect various blood cell counts, white blood cell classification and hemoglobin content.
2. Hematocrit: obtained by multiplying the average volume of red blood cells by the red blood cell count.
3. Red blood cell distribution width: represents the degree of consistency of red blood cell size. When the red blood cell size is uneven, the red blood cell distribution width value increases, such as various types of nutritional deficiency anemia.
4. The three average indices of red blood cells are used to identify the type of anemia.
(1) The average hemoglobin content of red blood cells: increased in megaloblastic anemia, decreased in iron deficiency anemia, chronic blood loss anemia, uremia, chronic inflammation.
(2) Mean volume of red blood cells: increase in hemolytic anemia and megaloblastic anemia; decrease in severe iron deficiency anemia and hereditary spherocytosis.
(3) The average red blood cell hemoglobin concentration: decrease in chronic blood loss anemia, iron deficiency anemia; various diseases can be in the normal range. In megaloblastic anemia, the mean red blood cell volume increases, the mean red blood cell hemoglobin amount increases, the mean red blood cell hemoglobin concentration is normal, and the red blood cell distribution width increases.
5. Average platelet volume: the average volume of each platelet, the size of platelets is related to its function.
(1) Increased: seen in patients with idiopathic thrombocytopenic purpura, edema and proteinuria in late pregnancy.
(2) Decreased: seen in non-immune platelet destruction, aplastic anemia, thrombocytopenia repeated infection syndrome, chronic myeloid leukemia, etc.
