Four strokes to deal with dead vegetables
Fully decomposed base fertilizer
If chicken manure, duck manure and other manure are used as the base fertilizer, it is necessary to combine the high temperature shack to make the manure fully fermented and decomposed and then plant the seedlings. If the shed period is short and there is no time to suffocate the shed, it is recommended that the vegetable farmers directly use the fermented and rotted commercial organic fertilizer. Once a seedling is planted by burning roots, the plant must be taken before the planting of the seedlings to promote rapid maturity of the manure in a short period of time. Before the planting, it is necessary to increase the ventilation and release the harmful gas generated by the manure decomposing out of the shed.
Pay attention to the dosage of the application of pesticide or bacterial fertilizer
In recent years, soil-borne diseases have become more and more early and more and more serious. In order to prevent diseases, vegetable farmers often take the method of applying pesticides or bacterial fertilizers in addition to the roots of pesticides to promote root disease prevention, but often due to improper use. The seedlings are victimized. Here to remind the vegetable farmers, whether it is the medicinal roots or points, must pay attention to the amount. In addition, after applying the medicinal or bacterial fertilizer, the agent or bacterial fertilizer directly contacts the roots of the plant, which may easily cause root injury, root burning or smoked seedlings, resulting in delays in planting the plants after planting. Therefore, it is necessary to mix the medicinal or bacterial fertilizer with the soil in the hole before planting the seedlings to avoid problems.
The depth of planting should be good
After seedlings are planted, they often die due to stem-based rot and disease. The occurrence of these two diseases has a lot to do with the planting of seedlings. The planting is too deep, the base of the stem of the seedling is buried in the soil, the watering is too much at the initial stage of planting, the external temperature is high, the water vapor is volatilized upwards, the temperature at the base of the stem is high, and the epidermal tissue of the base of the neck is destroyed, which leads to the infection of the disease. . Therefore, when the vegetables are planted, it is necessary to pay attention to the depth. It is best to ridge cultivation, in order to prevent the ground temperature from rising, it can be a small ridge.
Watering should be timely and appropriate
Planting vegetables in the hot season, the soil moisture evaporates quickly, and the plant transpiration is strong. After the seedlings are planted, the vegetable farmers must not control the watering for the seedlings. In addition to pouring the planted water, it should be poured 1 or 2 times of water, that is, "slow seedling water", in order to facilitate rapid seedlings. After pouring the “planting water†and “slowing waterâ€, the main focus is on the seedlings, which can extend the watering time appropriately. The water can be watered 10 to 15 days after the seedling water is cooled. Only when watering is properly watered can the vegetable roots be deeply rooted and strong trees formed.

Suction blood vessel is also called vacuum collection blood vessel, according to the type of a total of nine categories. The details are as follows :1. Red head cover, no additives, used for the determination of some biochemical and immune indicators. 2. Yellow head cover, containing coagulant, can be used for biochemical and drug test determination. 3. Black cap, which is mainly used for the determination of erythrocyte sedimentation rate. 4. Light blue cap for the determination of coagulation factors. 5. Green cap for blood gas analysis and hematocrit measurement. 6. Light green head cover, liver function, blood lipid, blood sugar and so on were measured. 7. Grey cap, which is a special test tube for measuring blood sugar. 8. Purple head cover, mostly used for determination, blood type, blood routine, glycosylated hemoglobin and so on. 9 orange head cover, used for the determination of serum, hormones and so on.
