Eggplant "half madness," also known as eggplant verticillium wilt, also known as black heart disease. In the early stage of disease, the leaves and veins of the eggplant become yellow, and then the whole leaf or half leaf gradually becomes yellow. The main veins of the leaves grow in a curved direction, and they are obviously biased towards the side of the leaves, and the leaves are not uniform. After removing the diseased plants, the vascular bundles in the middle of the plants became discolored and gradually turned brown or black. The early diseased leaves showed wilting at high temperatures in sunny days, which could be recovered sooner or later or on rainy days. The late-stage diseased leaves gradually dried from yellow to brown, and the leaf margins rolled up. In severe cases, the leaves turned brown and fell off. Half of the madness (Verticillium dahliae) is one of the major diseases of eggplant at present, and it can cause serious damage when severe. Eggplant "half madness" is a fungal disease. The pathogens spread with wind, rain, irrigation water, agricultural operations, etc. The diseases of high temperature and high humidity are aggravated, and the growth temperature of pathogens is 20-25°C. In addition, premature eggplant colonization, transplanting roots with soil, root injury, cultivation of buried too deep, continuous cultivation for no more than 3 to 4 years, the use of unripe farmyard fertilizers, excessive use of nitrogen fertilizer can cause the disease. Control methods: First, the method of grafting seedlings is adopted for cultivation. The second is the rotation of non-solanum crops for more than 4 years. The third is to increase organic fertilizer, phosphorus and potassium fertilizer applied rationally. The fourth is a reasonable dense planting. Fifth, timely watering, improve plant resistance. Sixth, at the early stage of disease, we used carbendazim WP 500 times or Koto 800 times to irrigate the roots. Each irrigating solution was 500 ml, about 7 days, and it was irrigated 3 times. For diseased strains can also be taken to remove the way to avoid cross-contamination. And with nitrocarbazone spraying control. 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.
