If cucumbers are to be highly profitable, the characteristics of the varieties, the growing season, the post-harvest use, the length of the transport time and the mode of transport, the length of the storage time, the storage method, the length of the sales time, and the sales method should be taken into account when harvesting. In practice, the following issues should be noted.
First, control the water before mining
The cucumbers that need to be transported and stored for a long distance and stopped watering 2 to 3 days before harvesting can effectively enhance their storability, reduce decay, and extend the postharvest preservation period of cucumbers.
Second, the safety interval
Cucumber production should use pesticides that are allowed to be used in the production of pollution-free vegetables. For the sake of consumer safety, they can only be harvested when the pesticide safety interval is reached.
Third, timely harvest
Harvesting should be timely, and the harvested product should be harvested at a low rate, the product should not reach the standard, and the flavor, quality and color should not be good. Too late harvesting will not only affect the production, but also impede the storage and transportation of the product. The cucumbers that are generally sold in the field can be harvested at an appropriate date. Long-term storage and long-distance transport of cucumbers must be harvested as soon as possible; harvested cucumbers in the winter can be harvested in due time; harvested cucumbers in the summer should be harvested as early as possible; The cucumbers circulated in the chain can be properly harvested at a late date. Cucumbers circulated at room temperature should be properly harvested early; the winter and spring prices that are more expensive can be harvested earlier.
Fourth, to prevent damage
Cucumber is very vulnerable to mechanical damage, so pick it up gently to prevent mechanical damage. Mechanical damage is the enemy of post-harvest storage and circulation preservation. Mechanical damage can not only increase the respiratory metabolism of vegetables, reduce resistance, and degrade quality, but also cause microbial infestation and rot.
V. Avoiding rain and dew
Do not harvest after the rain and dew, otherwise it is difficult for cucumbers to keep fresh and can easily cause rot.
Sixth, low temperature harvest
As far as possible, harvesting in the morning with the lowest temperature in the day can reduce the field heat carried by the cucumber and reduce the respiration of the vegetable body, which is beneficial to the post-harvest quality maintenance. Avoid harvesting at high temperatures and exposures.
Seven, harvesting techniques
Hold the melon in one hand, gently cut the handle with scissors, leave the stem to about 1 cm long, and wipe the dirt off the peel.
Classification by use
Acid and alkali resistant gloves, electrical insulating gloves, radiation protection gloves, medical gloves and other rubber gloves.
According to the rubber raw material or manufacturing process, it is divided into Latex Gloves and molded gloves.
Acid and alkali resistant gloves should be able to be used in sulfuric acid (density 1.32) or caustic soda solution (density 1.19) at 45°C. Electrical insulating gloves are divided into two types: high voltage and low voltage. High voltage can be used below 6000 volts (test voltage is 12000 volts). Low voltage can be used below 1000 volts. Medical gloves are divided into two types: light surface and wool surface (hair surface gloves or wrinkled gloves).
Sort by material
According to the material, it is generally divided into plastic disposable gloves, latex disposable gloves, and nitrile disposable gloves;
Among them, plastic film gloves are generally used in non-professional occasions. The advantage is that they are cheap, but because plastic disposable gloves are not elastic, their durability and suitability are relatively poor;
Latex gloves are usually used in professional occasions, such as operating rooms, laboratories and other places that require high sanitary conditions. The advantage is that they have a certain degree of elasticity and are more durable, but they are not resistant to animal oil corrosion, and are easily corroded by contact with animal oil. More importantly, according to statistics, 2%-17% of people will have varying degrees of allergy to latex.
Nitrile Gloves, in addition to having the characteristics of latex gloves and improving the shortcomings of latex gloves, can first withstand the corrosion of animal oils and fats, and will not cause allergies.
