The following reporter summarized the different pruning methods and management priorities adopted by vegetable farmers as follows, for farmers' friends to learn from:
Pre-primary results Late collateral results
The pruning methods of long-stemmed varieties such as Breitah and 702 are generally dominated by the main branches before the Spring Festival, and rely mainly on the lateral branches after the Spring Festival.
First of all, we must pay attention to the time of caring. In the production of greenhouses, the early picking of eggplants makes it difficult to shorten the growth and development of the eggplants, and the yield is reduced. When the picking of the hearts is too late, the plants grow up too fast and the top stems and leaves contact the shed film. On the one hand, the growth of the eggplants is inhibited and the photosynthetic efficiency is reduced. On the other hand, water vapor in the shed will form condensation on the membrane when the humidity is relatively high, and the disease in the leaf will easily increase.
It is recommended that the picking of the eggplant in the vegetable shed should not be completed in one shot, but it should be done in batches and in batches. The eggplant plants can be roughly treated according to the first face of the greenhouse to be exposed to the greenhouse film (the growth point is 10 cm from the greenhouse film is suitable), from front to back, and then to the middle of the greenhouse and the outlet of the eggplant plant topping .
Second, we must pay attention to the method of picking the heart, or choose a continuous picking. When topping, leave 1-2 leaves above the top of the plant. The main purpose of leaving 1-2 leaves is to provide the growth and development of the solanum by the photosynthate produced by it. In addition, picking up the heart should be carried out on a sunny morning in order to facilitate the wound healing caused by the picking of the heart and to prevent the infection and disease of the pathogen. If there are virus plants in the shed, they must be individually treated after the other normal plants are picked up to prevent contact infection. The stems and leaves of the eggplant obtained from the heart-picking should be taken out of the shed to be buried.
For the planting of dense, congested stems and leaves, growing weak eggplant should not be topping. Otherwise, after topping, due to increased number of branches, ventilation and light reduction, flowering and fruit setting are easily affected.
The pruning method is a common method adopted by vegetable farmers and is easy to grasp. The defect of the pruning method is that the fruit on the main branch is left empty for a long period of time after the removal of the fruit on the main branch. If the price of the long eggplant goes up, the vegetable farmers can only blink.
Main branch topping
Although the pruning method of “principal branches before Spring Festival and results of collateral branches after the Spring Festival†was popular, with the increase in the number of years of planting, there were also vegetable farmers who had worn out the method of pruning “for continuous picking†in order to pass through the main branches and lateral branches. Topping, to avoid the situation of eggplant picking up and down, to ensure the continuity of the plant results, the amount of picking each egg is stable, there will be no faults.
specific method:
The first branching of the main branch can be carried out when the plant grows to a height of 1 meter, and the lateral branches below the top of the eggplant are taken as the new main branch. The growth of this side branch is strong and the growth of the plant can be avoided.
The second picking was carried out when the plant height was about 1.4 meters; when the third picking was done, the plant grew to about 1.8 meters, ie the plant height reached the wire. After topping, the results of vigorous lateral branches that sprouted in the lower part were taken and the results were removed.
Note: The collaterals do not leave leaves. Many farmers think that leaving a leaf blade for photosynthetic use to produce nutrients during collateral removal will facilitate the germination of collateral shoots. If the plant is really weak, leave a leaf. When pruning is performed, one bud is left on each side and all the others are removed. The reason why no leaves are left is that the main branch has a long growing season and a large area of ​​single leaves. The photosynthetic nutrients can supply the growing needs, and it is necessary to properly remove some leaves in the deep winter to increase the transparency of the plants. If the leaves are left on the side branches, the number of plant leaves is too much, affecting the light transmission between the plants, but affect the fruit quality.
At the same time, regardless of the results of the main branch, or side branch results, the number of disposable fruit should not be too much, leaving 2 fruit can be, to avoid a large number of one-time results and affect the fruit set of the upper eggplant.
A variety of options can not be loose
The reporter needs to remind the vegetable farmers that no matter what kind of pruning method is adopted, management cannot be relaxed.
For different pruning methods, the management of fertilizer and water is also somewhat different. The focus of the management of fertilizer and water in the former pruning method should be focused on strengthening fertilizer and water management. Because after a long time of growth, eggplant yield is high, eggplant topping, is an adjustment of the plant, change the top edge, increase the branch, it is necessary to add fertilizer water, raise trees, promote trees.
After four or five months, the nutrients in the soil are consumed in large amounts, and it is difficult to meet the needs of a large number of eggplants. A large amount of elemental fertilizers such as Toyota A and Month Fertilizer should be supplied in time to promote the rapid growth of roots and upper leaves and stems. It should be noted that the time for supplementing nutrients must not be carried out after all the fruits have been removed, so as not to cause the crops to be leggy due to the lack of fruits, which may have a large impact on the yield. It is recommended that 1-2 fruits remain on the main trunk and have been enlarged. More fertilizer management measures.
For the latter kind of pruning method, the management of fertilizer and water should ensure continuity, because it is a continuous picking change, and should pay more attention to it. During the low temperature period in winter, it is recommended that the roots and trees be cultivated at the same time.
In addition, we must strengthen the prevention and control of long-stemmed tomato diseases.
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.
