When do Lingwu long jujubes ripen and hit the market? Their shelf life can be increased 10-fold
Yesterday, reporters learned from the Science and Technology Department of the Autonomous Region that the department, together with the Forestry Department, organized experts in forestry, fruits and vegetables, and food to conduct an on-site acceptance inspection of the room-temperature preservation research portion of "Key Technology Development and Research on Storage, Transportation and Preservation of Lingwu Long Jujubes," the region's first project tendered nationwide. The results showed that the shelf life of Lingwu long jujubes has increased 10-fold compared with before, achieving 30 days of room-temperature storage. It is reported that Lingwu long jujubes have long entered high-end markets such as the southeast coast and Hong Kong, China, but because Lingwu long jujubes are prone to losing

Detailed Guide to Peach Storage and Preservation Techniques, Extending Peach Storage Life
Some peach varieties ripen during the high-temperature summer season, and their harvest maturity and eating maturity are reached almost simultaneously; in addition, the fruit is soft and juicy with poor storability. However, storability varies greatly among varieties: honey peaches have the worst storability and can only be stored for about 1 week, while late-maturing varieties such as Fei peach, winter peach, and Qingzhou honey peach are relatively more storable. The main problems that easily occur during peach storage include: over-ripening and softening, rot caused by pathogenic bacteria, and chilling injury. The main technical measures adopted in production include: (1) Immediately pre-cool the fruit after harvest: immerse the fruit in 0

How to control the jujube bud weevil? Understanding its life habits is key
The jujube bud weevil belongs to the order Coleoptera, family Curculionidae. It occurs in Henan, Hebei, Shanxi, Liaoning and other famous jujube-producing areas, mainly harming jujube, apple, pear and other fruit trees. The jujube bud weevil emerges from the soil in early spring and first damages the young buds of jujube trees. It is the earliest pest to appear on jujube trees. When the population density is high, it can eat all the jujube leaves, causing a second flush of buds and resulting in reduced yield or total crop failure. The adult is dark gray or earth-yellow, with a black head, two curved elytra that are 2 times as long as wide, and a silvery-gray ventral surface. The eggs are milky white, turning brown later, oblong,

Detailed Explanation of the Damage Characteristics and Life Habits of the Jujube Gall Midge
The jujube gall midge, commonly known as the leaf-rolling maggot or jujube maggot, damages the young leaves of jujube trees with its larvae, causing the affected leaves to curl lengthwise toward the upper surface. Early-stage curled leaves are purplish-red, while late-stage curled leaves are mostly brownish-green. The damaged leaves gradually wither, scorch and drop off. The jujube gall midge produces 5-6 generations per year and overwinters as larvae in the shallow soil beneath the trees. In late April the larvae begin to curl leaves and cause damage, with early May being the peak damage period. The pupal stage of the first generation occurs in early June, and adults emerge in early June. In the Beijing area, it occurs in large numbers in May and June, causing the most severe damage, and the larvae mature in about 10 days. In late August

How to store pears in spring? Four methods to help you extend their shelf life
1. Chemical fumigation method. The fumigation method mainly prevents and controls diseases that invade the fruit. First, seal the pears with plastic film, then place a fumigant (such as acetaldehyde) inside the sealed plastic film so that the fumigant concentration inside the plastic film reaches 0.5% and is maintained for 180 minutes, or so that the fumigant concentration inside the plastic film reaches 1% and is maintained for 120 minutes. 2. Medicinal solution soaking method. This method mainly prevents pears from being infected by pathogens after harvest. Soak the pears in a 400-fold dilution of 4% Nongkang 120 fruit tree-specific solution for 50 minutes, then remove and air-dry, then package and store
