It is difficult to remember these five points during the flowering period of strawberries.

Adjust temperature and humidity

The flowering period of strawberry is very sensitive to temperature, the pollen germination rate will be reduced when the temperature is over 30℃, and the pistil will suffer freezing damage if the night temperature drops below 0℃. Cover the middle shed when the temperature is around 5℃, and cover the small shed when the temperature is below 0℃. In case of low temperature and low light, measures should be taken to supplement light and increase temperature in time.

The air humidity in the shed should be kept at about 40%. Too much or too little humidity will affect the quality of pollination, which will affect the flowering and fruit setting of strawberries. Let the air be released around noon every day, flexibly control the size of the air outlet and the air release time, and do not affect the temperature of the shed due to the dehumidification, especially in the case of rainy weather, although the humidity in the shed needs to be dehumidified, but at this time, heat preservation is needed. Time to let go.

Appropriate fertilization and water

Plants in the flowering and fruiting period of strawberries require more phosphorus and potassium fertilizers, but nitrogen fertilizer is also important, so pay attention to the amount of application to prevent strawberry growth. Because strawberry root system is concentrated in 15 cm soil layer, small high ridge cultivation is prone to lack of water, so it should be combined with fertilization and watering. During the flowering and fruiting period, depending on the growth of the plant and the flowering and fruiting situation, a small amount of topdressing can be used for several times, generally 3 to 5 times. Strawberries are not tolerant to fertilizer, so the fertilizer concentration should not be too high, and should be fully irrigated during the two fertilization periods, mainly drip irrigation.

At the same time, some foliar fertilizers containing calcium, iron, zinc and other trace elements are sprayed outside the roots, such as sea spirit biostimulant + 99% high-purity potassium dihydrogen phosphate (source of phosphorus and potassium) to improve strawberry fruit quality and yield. The color and hardness of strawberries can also enhance plant disease resistance and stress resistance.

Improve pollination effect

In the flowering greenhouse, the wind is weak and insects cannot enter from the outside. It is no longer feasible for strawberries to use wind to pollinate insects. The preferred method of pollination by bees is to use drones for better pollination. 3 sheds with 1 box of drones, placed alternately between sheds.

The time for placing the bees is generally 7 to 8 days before the strawberry blooms. Put the drone boxes in the greenhouse so that the drones can fully adapt to the microclimate and environment in the greenhouse before the flowers bloom. After releasing the queen bees, spray pesticides with low toxicity to the bees and move the hives out of the shed for more than 3 days.

Strengthen cultivation management

Remove old leaves, lateral buds, and stolons. Old leaves not only consume nutrients, affect ventilation and light transmission, and are prone to disease, but also tend to form more weak side inflorescences and small flowers and small fruits. Therefore, the old leaves and side buds should be removed in a timely and appropriate amount, and taken out of the garden to destroy or bury them deeply. After the apical inflorescence is tapped, choose to leave 1 to 2 well-positioned and strong side buds, and remove the rest. Later, the side buds that are tapped should also be removed in time. Each plant retains 8-12 effective functional leaves. Varieties with smaller leaves or weak branches, or large spacing between adjacent plants, can retain more tiller buds and lateral branches.

Pest Control

Strawberry flowering and fruit diseases mainly include gray mold, powdery mildew, etc. Attention should be paid to moisture control and disease prevention in rainy weather, and symptomatic agents are used for prevention and treatment.

Biological pesticides: eugenol, Bacillus subtilis, Trichoderma harzianum and other agents can be used; chemical pesticides: fluoxystrobin, trifloxystrobin, pyraclostrobin, fluoxamide, azoxystrobin and other agents can be selected. These agents can also treat the above 2 For various diseases, spray 2 to 3 times continuously, once every 7 days. Insect pests mainly include aphids, red spiders, thrips, etc., in the early stage of occurrence, the damage center should be blocked in time; thrips and aphids can be controlled by spraying matrine, fungicides, pyrethrins, etc.; spiders can be treated with matrine and azadirachtin, with low binding Toxic chemical pesticides such as bifenhydrazine, bufenofen-ethyl, hethiazox, etc.

Product Description

Disposable surgical medical products refer to items used in surgical operations, which are discarded after one use. These products are used to maintain a sterile environment and prevent the spread of infection during surgery.


Some common disposable surgical medical products include:
1. Surgical masks: used to cover the mouth and nose of medical staff during operations to prevent the spread of germs.
2. Surgical gowns: Medical staff wear these to protect their clothing from contamination during surgery.
3. Surgical Gloves: Healthcare providers wear these gloves to protect their hands from contamination during surgery.
4. Surgical Drape: Used to cover the patient and create a sterile field around the surgical site.
5. Surgical needles: Used to suture incisions and wounds during surgery.
6. Scalpel blades: These are used to make incisions during surgery.
7. Surgical Forceps: Used to grasp and manipulate tissue during surgery.
8. Surgical catheters: These catheters are used to drain fluids from the body during surgery.

Overall, single-use surgical medical products are critical to maintaining a sterile environment and preventing the spread of infection during surgery.
