Things to Keep in Mind When Selecting Fish Fingerlings in Winter and Spring
1. Pay attention to whether the fingerlings are uniform. If the fingerlings in the same pond vary in size, have relatively straight belly lines, thin and elongated tails, and slender bodies, then after being placed in a fish cage for 30 minutes they will show weak, sluggish movement, and some may even show symptoms of disease. Such fish cannot be stocked into ponds, nor are they suitable for long-distance transport; you may reduce the stocking density or move them to fertilized water for rearing. If they are indeed diseased, timely treatment is also needed. 2. Pay attention to the body length of the fingerlings. Whenever seining exercise is carried out, the fingerlings jump vigorously

How is rice dry-raised? Keep these thirteen points in mind
The trayless seedling-throwing technique for dry-raised rice uses a rice-specific slow-release medicinal-fertilizer super-absorbent seed coating agent called "Dry-Raising Nanny" to coat rice seeds, carry out dry seedling raising, and after pulling the seedlings, directly throw them into the field. It is a light, simplified, and cost-saving rice cultivation technique. Its key cultivation points are as follows: 1. Select the correct model. For application in dry-raised seedling throwing, the seedling-throwing type of "Dry-Raising Nanny" should be chosen. 2. Determine the dosage. Each bag (350 grams) of "Dry-Raising Nanny" super-absorbent seed coating agent coats 1-1.5 kg of rice seed. 3.

Detailed Explanation of Key Points of Potato Storage and Fresh-Keeping Technology
The edible part of the potato is the tuber, which contains a large amount of carbohydrates and rich mineral elements. Potatoes are resistant to storage and transportation and can be supplied year-round. They are a popular fresh-eating vegetable and raw material for processed products that help balance market supply during off-peak and peak periods. I. Storage and Characteristics. After harvest, potatoes generally have a dormant period of 2-4 months, and the length of the dormant period varies with different varieties. Late-maturing varieties have a short dormant period, while early-maturing varieties have a long dormant period. Different degrees of maturity also affect the length of the dormant period. The stem of immature potatoes has a longer

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

How rabbit keepers can spot a suspiciously sick rabbit as early as possible
Rex rabbits have delicate bodies and are sensitive to external conditions, with the characteristics of sudden onset, rapid death, and quick recovery with timely treatment. Because Rex rabbits mostly fall ill at night, observing cage by cage and nest by nest when feeding the rabbits in the morning makes it easiest to identify suspiciously sick rabbits, and specifically you can start with checking, looking, touching, and measuring. 1. Check: A healthy rabbit's ears are pink, and its eyes are bright. If the ears are red or light purple, it means the rabbit is overheated, and this can be relieved by placing it in a ventilated cage with little movement; if the ears are white and feel cool to the touch, it means the rabbit has drunk

Detailed Explanation of Key Techniques for Jujube Storage and Fresh-keeping
Jujube is one of the fruits unique to China. It is rich in nutrients, containing relatively large amounts of sugar, protein, fat, iron, calcium, phosphorus and other substances. At the same time, its content of vitamin C and cyclic adenosine monophosphate (CAMP) is also very high. In clinical medicine, it has preventive and therapeutic effects on the human body in terms of antioxidation and increasing myocardial nutrition, and is therefore favored by consumers. However, jujube fruit is a fruit that does not store well. At room temperature, it loses its original quality in about 20 days, and at low temperature it can only be stored for 40-60 days. Therefore, the storage and fresh-keeping technology for jujube fruit

How to keep pears fresh for storage? Master these methods to store them longer
(1) Raised-bed pit storage method. This is a main storage method used in the Huangxian Changba pear producing area. Before harvesting the pears, choose between-row spaces in the orchard with good ventilation, cool and dry conditions, and a low water table. Build raised beds running north-south, with a bed width of 1.5 m to 2 m; the bed length depends on the storage quantity. The bed surface should be about 10 cm above the ground, slightly higher in the center and slightly lower on both sides, with ridges about 15 cm high built up around the perimeter. Spread a layer of fine sand 5 cm to 10 cm thick on the bed surface. At the four corners of the bed ridges and along the two long sides, drive a wooden post every 750 mm, with a post height of 750
