Detailed Explanation of Key Points for Storage and Fresh-keeping Techniques of Peaches, Plums and Apricots
Peach, plum and apricot (including cherry) fruits all contain a hard stone and belong to the drupe category of fruits, sharing common characteristics in fruit development and postharvest physiology. It is precisely because the fruit contains a hard stone that a double-S growth curve appears during growth. Peach, plum and apricot fruits have high respiration intensity; all have a respiration peak, so they all belong to the climacteric type of fruit, which determines that they have basically similar storage, transport and fresh-keeping technical measures. However, as tree species and varieties differ, the storage, transport and fresh-keeping techniques adopted also differ. Peaches and plums generally

Key Points of Mushroom Harvesting, Storage and Fresh-keeping Techniques
I. Storage Characteristics and Varieties Mushrooms are rich in amino acids and protein and have a delicious flavor. However, after harvest, mushrooms respire vigorously and at room temperature quickly open their caps, turn brown, develop off-flavors and deteriorate in quality, so they can only be stored for a short time. Dried mushrooms are easy to preserve, but their nutritional value decreases, and delays in processing can cause serious losses. Therefore, measures must be taken after harvest during storage, transport and sale and before processing to prevent a decline in mushroom quality. There are many cultivated varieties of mushrooms, and common ones include oyster mushroom, shiitake, button mushroom, enoki mushroom and phoenix mushroom.

Detailed Explanation of Key Points of Lily Bulb Storage and Fresh-Keeping Techniques
I. Choose storage-tolerant varieties. China is the country of origin for lilies, with many cultivated types and varieties. The main ones include Longya lily, Chuan lily, and tiger lily (Lilium lancifolium) and other variants. Among them, the Chuan lily, which is white, flat-spherical, tightly clustered, large, and sweet-tasting, has good quality and stores well. Lilies are generally harvested in early November, mostly by digging out the bulbs with a spade, promptly removing the stems and soil, and cutting off the fibrous roots. Newly dug bulbs must not be exposed to wind and sun in the field, to prevent the outer scales from discoloring and losing water. II. Pre-cool and select the bulbs. After harvest, lilies should be promptly transported to a shady place and evenly

Detailed Explanation of Key Points of Oyster Mushroom Storage and Fresh-Keeping Techniques
Fresh oyster mushrooms have a high water content and tender, crisp tissue, making them extremely prone to damage. If stored improperly, they easily rot and deteriorate, causing losses to producers. Several storage methods for oyster mushrooms are introduced below: 1. Fresh storage: The storage time of fresh oyster mushrooms at room temperature is greatly affected by temperature and air humidity. When the room temperature is 3°C-5°C and the relative air humidity is around 80%, fresh mushrooms can be stored for one week. As temperature increases, humidity must also increase. When the quantity of mushrooms is small, the oyster mushrooms can be placed in a vat containing a small amount of cold water, and the vat opening sealed tightly; even if the temperature reaches 15°C-16°C, they can be kept fresh for about one week.

Storage and Fresh-keeping Techniques for Peach, Plum and Apricot Fruits (Part Two)
III. Pre-storage Agricultural Measures for Peach, Plum and Apricot 1. Selection of Storage Varieties Early-maturing varieties are not tolerant of storage and transport, such as honey peach and Wuyuexian. Mid- and late-maturing varieties have better storage and transport tolerance, such as Feicheng peach, Qingzhou honey peach and Shaanxi winter peach, which are relatively tolerant of storage and transport; varieties such as Okubo and Gangshanbai, Yanhong also have good storage and transport tolerance. Clingstone varieties and soft-fleshed varieties have poor storage and transport tolerance. The storage and transport tolerance of plum and apricot is similar to that of peach; varieties such as Niuxin plum and Hebei rock sugar plum have good quality and are also tolerant of storage. 2. Pre-harvest Agricultural Technical Measures Pre-harvest

Key points of flowerhorn cichlid keeping techniques in aquariums
Flowerhorn (F1owerhorn) is a general term for the multi-hybrid descendants of several species in the family Cichlidae (Cichlaidae), mainly from parents of the genus Cichlasoma. Because of their strange appearance and brilliant colors, flowerhorns were sought after by a large number of ornamental fish enthusiasts as soon as they appeared, becoming popular throughout Asia within three or four years and becoming a new favorite among ornamental fish. It has been only 10 years since the birth of the flowerhorn, and only 5 years since it entered mainland China. Its keeping techniques are introduced below.

Detailed Guide to Apricot Storage and Fresh-Keeping Methods and Techniques
Storage and Fresh-Keeping of Apricots 1. Determining the Suitable Harvest Maturity of Apricots Determining the suitable harvest maturity is key to storing apricots. The judgment of maturity can be determined based on factors such as the number of days of fruit development, changes in fruit color, the texture of the peel and flesh, the aromatic flavor of the fruit, and the firmness of the fruit's attachment. Apricots intended for storage should be harvested when the fruit has reached the inherent size of the variety, the fruit surface has turned from green to yellow, the sun-facing side shows the variety's inherent color, the flesh is still firm, nutrients have been fully accumulated

Breeding Methods and Key Keeping Techniques for the White Cloud Mountain Minnow
Morphological Characteristics of the White Cloud Mountain Minnow The White Cloud Mountain minnow, also known as the Baiyun Mountain fish, Tang fish, red-tailed fish, and colorful golden-line fish, belongs to the Cyprinidae family and originates from Guangdong, China. The White Cloud Mountain minnow was first discovered in the Baiyun Mountain in the northern suburbs of Guangzhou, Guangdong Province, China, hence the name Baiyun Mountain fish. The White Cloud Mountain minnow is about 3-4 cm long, with a spindle-shaped, slender body that is slightly laterally compressed, a small head, large eyes, and a bluntly rounded snout. The back of the fish is tea-brown with a slight blue tinge, the belly is silvery white, the dorsal fin and caudal fin are bright red, the tips of the pelvic fins are yellow, and the center of the tail is also red.

Practical Guide to Fresh-keeping and Processing Techniques for Shiitake Mushrooms
1. Drying equipment: Although shiitake drying equipment at home and abroad differs in form, scale and technical level, its principle is basically the same. Generally there are the following models: (1) forced circulation dryer; (2) forced ventilation parallel-flow dryer; (3) heat pump dryer. 2. Drying methods (1) Raw material handling Before drying, trim off the mushroom stalks or stem bases from the freshly picked mushrooms, remove impurities, and process after grading. Mushrooms picked on rainy days or with high moisture content should first be spread out to air-dry so that

Research on Storage and Fresh-keeping Techniques for Jujube Fruit
Jujube is one of the fruit trees unique to China, with a cultivation history of over 2,000 years. The jujube tree is cold-resistant, drought-resistant and tolerant of poor soil, with strong adaptability, and is known as the "ironclad crop." Jujube fruit is rich in nutrients, containing more than twice the sugar of ordinary fruits as well as relatively large amounts of protein, fat, iron, phosphorus, calcium and other substances, and has high nutritional value and dietary therapy functions. Domestic research on fresh jujube storage and its postharvest physiology began in 1980, and studies and explorations have been carried out on the postharvest physiology and storage of jujube, with a great deal of work done on physiological and biochemical mechanisms.
