Ginger is an important condiment, and its planting efficiency is high. In combination with previous ginger production, the following plant management recommendations are proposed:
First, avoid blindly following the wind to grow ginger
For ginger farmers in the main producing areas of ginger, due to their familiarity with ginger management techniques, they can be planted appropriately according to local soil conditions, water conditions, their own labor force, and their own ginger cellar storage capacity. Because the ginger is not frost-resistant, the harvesting period is concentrated, and the planting area must not be too large to prevent the ginger from being frozen in time. For farmers who have just started planting ginger, we recommend small-scale planting, focusing on the laws of growth of ginger, studying planting management techniques, and accumulating experience in production management, and must not blindly plant large areas.
Second, bogey blindly use fertilizer, increase production costs
According to the research of Shandong Agricultural University, the recommended amount of fertilizer per mu is 6000-7500 kg for ring fertilizer, 100-150 kg for compound fertilizer, and 100 kg for water. Some vegetable growers do not understand the amount of fertilizer required for ginger, planting 1 mu of ginger to use about 500 kg of fertilizer, on the one hand caused a lot of waste of fertilizer, on the other hand increased production costs. Before the three-horse stage, ginger is grown on its own nutrients. Therefore, the base fertilizer must be fully applied with organic fertilizer, with emphasis on nitrogen fertilizer and light application of potassium fertilizer. From June to July, the topdressing fertilizer is mainly nitrogen fertilizer, which can be supplemented with a small amount of potash fertilizer. After cultivating soil with Liqiu ridge, its growth rate is accelerated and its growth is increased. Not only does it need to absorb large amounts of nutrients such as nitrogen, phosphorus, and potassium, but also it needs a small amount of trace elements such as calcium, magnesium, boron, and zinc. 8-10 months is the peak period for the growth of ginger block. The enlargement of ginger block needs to absorb a lot of nutrients, especially potassium. Therefore, it is necessary to flush potash fertilizer several times during this period and to supplement nitrogen fertilizer properly.
Third, bogey contempt prevention, passive treatment, medicine is not symptomatic, prevention and treatment of pests and diseases is not effective
The contempt for passive treatment is not active prevention, but passive control of pests and diseases. Reluctant to spend money on drugs, there is a fluke, can not fight without drugs, can delay drug fights to delay, once the pests and diseases, they panic, remembered to fight drugs. Because we can't take the initiative to do a good job of early prevention and control of pests and diseases, we missed the best opportunity to prevent and control, we had to passively prevent and treat pests and diseases, and it took time and effort to spend money. Lack of basic knowledge of pest control, can not be symptomatic medication. They do not understand the knowledge of pest control, follow other people's medication, or listen to the practitioner's introduction of blind medication. According to the early monitoring of pests and diseases, the best time for prevention and treatment should be determined and early prevention should be actively and timely conducted as soon as possible. Good prevention and control of a certain kind of pests and diseases, one should be symptomatic medication, choose a good suitable pesticides, and second, proper use of pesticides, good medicine and good methods are the key to the success of pest control. Pay attention to the use of pesticides and the use of time, clear use of methods in order to maximize the effectiveness of pesticides to achieve the desired control effect.
Fourth, avoid light weight ginger, only pay attention to yield
High yield is not necessarily efficient, and the effectiveness of ginger is determined by the output and price. When ginger was purchased, the main criteria for determining the price of ginger purchase were ginger color, brightness, and ginger size. According to the situation we have promoted for many years, after germination of ginger, the production of fulvic acid by a large amount of flushing can be significantly improved, which can significantly improve the color and brightness of ginger. After potash application time moved to August-September, the application of potash fertilizer by fractional flushing can significantly improve the color of ginger block and increase the weight of ginger.
Fifth, bogey despise ginger cellar storage management
1.The common serum tube red cap collection vessel contains no additives, no anticoagulant and procoagulant components, only vacuum. Used for routine serum biochemistry, blood bank, and serological-related tests, a variety of biochemical and immunological tests, such as syphilis, hepatitis B quantification, etc., do not need to shake after drawing blood. The sample preparation type was serum. After blood was drawn, it was placed in a water bath at 37℃ for more than 30min, centrifuged, and the upper layer of serum was used for reserve.
2. There is a procoagulant in the orange head of the rapid serum tube to accelerate the coagulation process. The rapid serum tube can coagulate the collected blood within 5 minutes, which is suitable for emergency serum series tests. It is the most commonly used coagulant test tube in daily biochemistry, immunity, serum, and hormone. After blood is drawn, it can be mixed reversely 5-8 times and can be placed in a 37℃ water bath for 10-20min when the room temperature is low, and the upper serum can be centrifuged for use.
3. Inert separation glue and coagulant are added to the yellow head cap Blood Collection Tube of inert separation glue. The specimens remained stable for 48 hours after centrifugation. The procoagulant can quickly activate the coagulation mechanism and accelerate the coagulation process. The type of serum preparation is suitable for emergency serum biochemical and pharmacokinetics tests. After collection, the mixture was reversed 5-8 times and stood upright for 20-30min before the supernatant was centrifuged and used.
4. The sodium citrate concentration required by the citrate erythrocyte sedimentation test tube with black cap is 3.2% (equivalent to 0.109mol/L), and the ratio of anticoagulant to blood is 1:4. Containing 3.8% sodium citrate 0.4mL, the blood was drawn to 2.0ml, which was a special test tube for erythrocyte sedimentation rate. The sample type was plasma, which was suitable for erythrocyte sedimentation. The blood was reversed and mixed 5-8 times immediately after the blood was drawn. It should be shaken again when it is used. The difference between it and the test tube for coagulation factors is that the concentration of anticoagulant is different from the proportion of blood and cannot be confused.
5. Sodium citrate coagulation test tube light blue cap Sodium citrate plays an anticoagulant role mainly by chelating with calcium ions in blood samples. The National Committee for Clinical Laboratory Standards recommends an anticoagulant concentration of 3.2% or 3.8% (equivalent to 0.109 or 0.129mol per liter), with an anticoagulant to blood ratio of 1:9. The vacuum tubes contained 0.2mL of 3.2% sodium citrate anticoagulant, and the blood was collected to 2.0ml. The sample preparation type was whole blood or plasma. After collection, the samples were immediately reversed and mixed 5-8 times, and the upper plasma was taken after centrifugation for use.
6. Heparin is added to the green head of the heparin anticoagulant tube. Heparin has a direct antithrombin effect and can prolong the coagulation time of the specimen. It is used in emergency and most biochemical tests, such as liver function, renal function, blood lipids, and blood glucose. It is suitable for erythrocyte fragility tests, blood gas analyses, hematocrit tests, erythrocyte sedimentation rates, and common biochemical tests. It is not suitable for hemagglutination tests. Excessive amounts of heparin cause aggregation of leukocytes and cannot be used for leukocyte counting. Because it can make the background of the blood stain pale blue, it is also not suitable for leukocyte classification. It can be used for hemorheological use, the sample type is plasma, and immediately after blood collection, it is reversed and mixed 5-8 times, and the upper plasma is taken for use.
7. The light green head of the plasma separation tube is added with heparin lithium anticoagulant in the inert separation rubber tube, which can achieve the purpose of rapid separation of plasma. It is the choice of electrolyte detection, and can also be used for routine plasma biochemical determination and ICU and other emergency plasma biochemical detection. It is used in emergency and most biochemical tests, such as liver function, renal function, blood lipids, and blood glucose. Plasma samples can be directly loaded on the machine and remain stable for 48 hours in refrigerated storage. It can be used for hemorheological use, the sample type is plasma, and immediately after blood collection, it is reversed and mixed 5-8 times, and the upper plasma is taken for use.
8. Potassium oxalate/sodium fluoride grey cap sodium fluoride is a kind of weak anticoagulant, usually with potassium oxalate or sodium ethylate combined use, the proportion of sodium fluoride 1 part, potassium oxalate 3 parts. "This mixture, 4mg, does not coagulate 1ml of blood for 23 days and inhibits glycogenolysis, is not useful for urease determination of urea, nor for alkaline phosphatase and amylase determination, and is recommended for blood glucose determination." It contains sodium fluoride or potassium oxalate or ethylenediaminetetraacetic acid disodium (EDTA-Na) spray, which can inhibit the activity of enolase in glucose metabolism. After blood is drawn, it is mixed reversely 5-8 times, and after centrifugation, the supernatant plasma is taken for use. It is a special tube for the rapid determination of blood glucose.
9. EDTA anticoagulant tube purple cap ethylenediamine tetraacetic acid (EDTA, molecular weight 292) and its salt is an amino polycarboxylic acid, suitable for general hematology test, is the first choice for blood routine, glycosylated hemoglobin, blood group test tube. It is not suitable for coagulation tests and platelet function tests. It is also not suitable for the determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase, and leucine aminopeptidase. 100ml of the 2.7%EDTA-K2 solution was sprayed on the inner wall of the vacuum tube, blown dry at 45 ° C, and blood was collected to 2mI. Immediately after blood was drawn, the mixture was reversed and mixed 5-8 times before use. The sample type was whole blood, which should be mixed during clinical use.
