How to store scallions for a long time? Practical storage techniques shared
Optimal storage temperature: 0°C Relative humidity: above 95%RH Scallions, like leafy vegetables in general, are suited to storage in a low-temperature, high-humidity environment. Above freezing, the lower the storage temperature the better (around 0°C), and the relative humidity should ideally be 98-100%RH. Therefore, they can be placed in a perforated plastic bag. Trimming the root ends of scallions before bundling can avoid bringing large amounts of waste to market. If hygiene is maintained during trimming to prevent the entry of pathogenic bacteria, the difference in storage life between trimming and not trimming is small. Commercial sellers may choose

Winter pond fish farming has many benefits, and winter is the right time to farm
Guangdong Province is located in the tropical and subtropical zones, with abundant water and heat resources. Taking the Guangzhou area as an example, the annual average temperature is above 23°C, and even in the coldest month, January, the average temperature still reaches around 13°C. This natural advantage is very favorable for carrying out "winter farming" of pond fish. Practice in various places has proven that "winter farming" of pond fish has many benefits: First, when the weather is cold and the water temperature is lower, the organic matter and fertilizer in the pond decompose slowly, the pond water is fresh, and oxygen is sufficient, which is conducive to rapid growth and easy fattening of pond fish; Second, because the weather is colder, bacteria and parasites in the pond are not easy to reproduce and grow, so pond fish

Method for Determining the Optimal Insemination Time for Sows by the Hand-Pressure Technique
The inseminator stands at one side of the sow in estrus, facing the sow's back, extends both hands flat, and gently places them on the sow's back, then gradually presses down with force. At this point, if the sow's back suddenly arches up and there is a sense of upward rebound, press down for another 1-2 minutes; if the sow stands still without moving, without continuous grunting or squealing, then this is the optimal time for insemination; if, when pressing down, the sow's limbs move forward and backward and she makes vocalizations, then it is not the optimal time for insemination.

Detailed Explanation of Angelica Harvest Time and Methods
For autumn direct-seeded angelica, harvest occurs in the second year; for transplanted angelica, harvest occurs in the same year, after the plants turn yellow and withered in mid-October. Natural conditions vary from place to place, so harvest times differ to some extent. For example, in Minxian, Gansu, harvest is 3 to 5 days after Frost's Descent; in production areas of Sichuan, harvest is around Frost's Descent; in Yan'an, Shaanxi, it is in late October or early November. Harvesting should not be too early or too late. If too early, the angelica is not yet fully mature, which reduces yield and quality; if too late, the soil freezes, the roots become brittle and break easily, causing excessive loss. Generally, it is best to harvest before the soil freezes and when the plants are yellow and wilted. About 10 to 15 days before harvest, first cut off the angelica stems and leaves, leaving stubble about 3 cm tall so the plants can be identified during harvest. This allows the ground to be exposed to the sun and speeds up maturation. At the same time, livestock trampling should be prevented to avoid rotting of the heads. When harvesting, dig with a hoe: first hollow out the soil beneath the plants, then dig them over from above and take them out. This allows the entire root to be dug out and prevents breaking or injuring the roots. After digging, in conjunction with turning the soil, pick up once more any roots that were missed or broken during digging. After harvesting, transport them back to the processing site and tie them into bundles for processing. Generally, the yield is 100 to 150 kg of dried angelica per mu, and high-yielding fields can reach 250 to 300 kg per mu.

Complete Analysis of Korean Pine Seed Collection Time and Methods
The time and methods for collecting Korean pine seeds are as follows: in natural Korean pine forests, the proportion of seed-bearing trees in 80-to-100-year-old stands accounts for over 91%. To solve the problem of insufficient Korean pine seeds, clonal seed orchards have been established, but they have not yet produced large quantities of seed. In natural forests, stands with good site conditions and vigorous growth are selected and designated as seed production stands, with intensified tending and management to prepare for seed collection. Korean pine cones mature from September to early October. When the cones turn from green to yellow-green and some seed scales begin to split, they enter the early ripening stage. After that, the seed scales gradually turn yellow, and individual cones begin to fall

August Is the Right Time for Foliar Potassium Spraying on Cotton
Because the content of available potassium (including water-soluble potassium and readily available potassium) in the soil decreases year by year, available potassium has become the number one demand in cotton nutritional physiology. When 30-40 jin of high-quality potassium fertilizer is applied in the base fertilizer, due to the consumption by cotton growth and development and leaching after heavy rain, by August the available potassium content in the soil will again drop to its original level. Entering August, as soil aeration deteriorates and the ground temperature drops after the cotton field closes its rows, the soil's potassium supply capacity weakens day by day. If potassium fertilizer cannot be supplemented in time, obvious potassium deficiency will appear

How Many Times Should a Rabbit Farm Be Disinfected? Master the Correct Disinfection Frequency
The disinfection theory in books says, "Twice a week in summer, once a week in the other seasons." I think this disinfection practice involves too many rounds. The purpose of disinfection is to kill harmful bacteria. My approach is once every half month in summer, and once a month the rest of the time. If you disinfect frequently, the goal is to kill harmful bacteria, but the result is that you kill all the beneficial bacteria too. Also, after we finish disinfecting, we sling the sprayer on our backs and turn around and leave the rabbit shed, leaving the rabbits in their cages reluctantly "inhaling the chemicals," and side effects are very likely to occur. According to what I have learned

How to reasonably choose the suitable sowing time for wheat?
The suitable sowing time for wheat generally refers to sowing when the average daytime and nighttime temperature in autumn steadily drops to 18-15°C. Within this range, sow semi-winter varieties first, then spring varieties. By making use of the suitable natural conditions such as temperature and light in autumn and winter, strong seedlings can be formed before winter, which is conducive to safe overwintering and improves the tillering and ear-bearing rate and grain weight. Right now is the critical season for wheat sowing, and wheat across the province has begun to be sown from north to south. According to the requirements of different regions and different types of wheat varieties for sowing time, and in response to the issue of suitable wheat sowing time that farmers generally care about, the following suggestions are put forward

Analysis of the reasons why first-time mother pigs refuse to nurse
For first-time mother pigs refusing to nurse, the solutions are: 1. Fix the nursing positions. After farrowing is complete, arrange the piglets around the lying sow with the weak ones in front and the strong ones behind, let them find the teats on their own, observe and adjust promptly, and after 2 to 3 days they will be fixed in an orderly arrangement. 2. Treat udder inflammation. Whenever the milk is plentiful and the piglets have just started sucking the teats, if the sow immediately lets out a scream, jumps up suddenly and even tries to bite the piglets, it means the sow has mastitis
