Harvest of bitter gourd should take into account the characteristics of bitter gourd varieties, growth season, post-harvest use, the length of transport time and mode of transport, storage time and length of storage, sales time and sales methods. The following issues should be paid attention to when harvesting:
Preharvest control of water requires long-distance transportation and storage of bitter gourd. Watering is stopped 2-3 days before harvest, which can effectively enhance its resistance to storage, reduce decay, and extend the postharvest preservation period of bitter gourd.
During the safe interval balsam pear production process, some pesticides that are allowed to be used in nuisance-free vegetables are used. For the sake of consumer safety, they can only be harvested when the pesticide safety interval is reached.
Timely harvesting and timely harvesting, premature harvesting and low yields, products fail to meet standards, and bad flavor, quality and color are not good; too late harvesting not only paralysed, affecting production, but the product is not resistant to storage and transportation . Bitter gourd generally sold on the spot, can be harvested properly; long-term storage and long-distance transport of bitter gourd should be harvested as early as possible; bitter gourd harvested in winter can be properly harvested late, bitter gourd harvested in summer to early harvest; cold Chain bitter gourd can be properly harvested in the evening, bitter gourd circulation at room temperature should be properly harvested early; market prices are more expensive winter and spring, can be harvested as early as possible.
Prevent damage When bitter gourd is harvested, take care to prevent mechanical damage, especially bitter gourd is very likely to cause 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.
Avoid rain and dew Do not harvest after rain and dew, otherwise bitter gourd is difficult to keep fresh and can easily cause rot.
Low-temperature harvesting is harvested as early as possible in the morning with the lowest temperature in the day, which can reduce the field heat carried by balsam pear and reduce the respiration of the vegetable, which is beneficial to the post-harvest quality preservation. Avoid harvesting at high temperatures and exposures.
The harvesting method holds the melon in one hand, cuts the handle gently with scissors, and the stem is left about 1 cm long, and the dirt on the peel is wiped off.
