What are the precautions during the pineapple harvest period? Latest key points explained in detail
Pineapple is one of the four famous tropical and subtropical fruits in our country, generally grown in Hainan, Taiwan, China and the Guangdong-Guangxi region, and summer is the peak season for pineapples on the market, so do you know how pineapples are harvested? What should be noted during harvesting? Let's find out together.
1. Harvest at the right time
The harvest time of pineapple must be appropriate; too early or too late will affect the quality of the fruit. The harvest time depends on the condition of the fruit, and the maturity of the fruit can be judged by its skin color and the sound when tapped with a finger. If it is to be sold to distant places, it is suitable to harvest when the fruit is 70 to 80 percent mature, when the small fruits at the base of the fruit begin to turn yellow, the surface of the fruit changes from green to yellow-green, the white powder falls off, the flesh begins to soften, and the flesh color changes from white to yellow; this is suitable for long-distance transport harvesting. If it is sold locally or for short-distance sales, the maturity can be slightly higher.
2. Harvest time
The time for pineapple is best after the morning dew has dried; it should not be harvested on cloudy and rainy days, so as to avoid rainwater penetrating the fruit and causing fruit rot during transport or storage, which affects fruit quality and returns and causes huge losses. When harvesting, handle gently to avoid mechanical damage, which would give pathogens an opportunity. After harvesting, grade the pineapples according to size, remove fruits damaged by pests, diseases or mechanical injury, and transfer them at random to a cool, ventilated place; after they are slightly dry, grade and pack them.
3. Fertilizing after fruit harvest
After the winter fruit is harvested, it is important to clean the orchard and fertilize in time, burn or fertilize the weeds and fallen leaves in the orchard in a centralized way, and apply fertilizer to restore tree vigor. Use high-quality organic fertilizer and nitrogen-phosphorus-potassium compound fertilizer as the main components, and appropriately increase the proportion of potassium fertilizer, which can improve the plant's nutritional level, enhance cold resistance, avoid frost damage, and at the same time increase nutrient accumulation, promote the tree vigor to recover as soon as possible, and enable the plant to grow as soon as possible when spring comes.
4. Storage work
The paraffin wax coating storage method can be used. When the fruit is 70 to 80 percent mature, select undamaged fruits for storage, put paraffin wax into a pot and boil it, let it cool slightly and congeal, then dip the pineapple into the wax liquid and immediately take it out, so that the fruit surface is evenly coated with a layer of wax, and then store it in a suitable environment. This method can keep pineapple fresh for more than 45 days at room temperature, and the peel remains fresh, maintaining the original color, aroma and taste.
