A Comprehensive Guide to Potato Processing Techniques
The potato is one of China's major agricultural products and can be grown all over the country, with enormous production potential. Besides being eaten fresh, processed into starch, or cooked into Chinese and Western fast food, potatoes can also undergo many kinds of further processing. 1. Potato jam First, wash the potatoes clean, remove any rotten or sprouted parts, then peel them, place them in a steamer and steam until cooked, then take them out and spread them to cool. Next, rub them through a sieve into a uniform potato mash and set aside. Take white granulated sugar, water and sour water (that is, the sour water used in a vinegar workshop; mix a small amount of thin rice (porridge) with bran and put it in a vat, transfer it from vat to vat for one week, once a day, and the filtered sour water is used as a vinegar starter), put them into a pot and boil until 110°C, then pour the potatoes into the pot, and use an iron shovel to keep turning them constantly, stirring while pressing, until all the potato mash is broken up, while at the same time preventing the bottom of the pot from scorching. Continue heating to 115°C, then add citric acid and coloring. And control its pH value at 3-3.2. At this point, because the temperature is too high, it is necessary to turn and stir frequently to prevent scorching. Lower the temperature with a low fire, and when the material in the pot reaches 100°C, add the fruit food flavoring and nutritional additives into the pot, stir evenly with an iron shovel, and it becomes potato jam.

What kind of fish is the silver crucian carp? A comprehensive introduction to its breed characteristics
The silver crucian carp, also known as the Japanese crucian carp, the Osumi crucian carp, the Kawachi crucian carp, etc. Because the silver crucian carp has advantages such as a wide feeding habit, fast growth, large individual size, a high catch rate, and few diseases, it can grow, develop, mature, and spawn well in all kinds of freshwater bodies in our country, and is generally welcomed by fish farmers. It has already been promoted over large areas in many provinces and cities in our country. 1. Breed origin The silver crucian carp is native to Japan's long-standing Lake Biwa.

Comprehensive prevention and control measures are needed for fish hepatobiliary syndrome
In recent years, with the continuous increase in the intensification of aquaculture, the incidence of fish hepatobiliary syndrome has been rising. Hepatobiliary syndrome can occur in various cultured fish, most notably in common carp and grass carp, and generally the incidence is high in adult fish. There are many causes of fish hepatobiliary syndrome, which can be summarized mainly in the following aspects. (1) Pathogenic microorganism infection.

A Comprehensive Guide to Scientific Control Methods for Soybean Aphids
Soybean aphids are commonly known as "ni chong" (greasy bugs) or "mi chong" (honey bugs). They mostly gather on the growing points, top leaves and backs of young tender leaves of soybean plants, piercing and sucking sap to cause damage. This results in leaf curling, plant stunting and reduced yield, and they can also transmit viral diseases, causing yield loss and quality decline. This pest begins to appear in soybean fields in mid-to-late June, and causes severe damage during hot, dry weather. Soybean aphids have a very strong reproductive capacity; a single female can produce 50-60 offspring, and under suitable conditions, young aphids can give birth after about 4-5 days, and can reproduce 15

Symptoms and Comprehensive Prevention and Treatment of Endometritis in Sows
When sows are mated, artificially inseminated, giving birth, assisted during farrowing, or experiencing miscarriage, if hygiene is not observed or disinfection is not strict, bacteria can be introduced into the uterus, causing reproductive infections in sows. Among these, Escherichia coli, Corynebacterium, Streptococcus, Staphylococcus, Pseudomonas aeruginosa, and Proteus are the most common, leading to endometritis. During farrowing, surgical manipulation of the birth canal or partial retention of fetal membranes in the uterus can also cause endometritis. If the floor of the pen is not kept clean, or if the sow moves around in a exercise yard contaminated with sewage, bacteria can also enter through the vulva.

Comprehensive Utilization Techniques for Fish Fingerling Ponds During the Winter Fallow Period
Using Winter-Fallow Fingerling Ponds to Raise Marketable Fish Raising a crop of marketable fish in winter-fallow fingerling ponds can both increase production and help regulate the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are concentrated in ponds, so as to make full use of the growing period. Based on a maximum water depth of 2 m, the usual stocking rate is 125-150 kg per mu. The usual stocking ratio is about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp. Stocked fish
