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

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

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

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.

A Detailed Guide to the Harvest Time and Processing Methods of Angelica sinensis
This product is the dried root of Angelica sinensis, a plant in the Apiaceae family. (1) Origin: mainly produced in Minxian, Wudu, Zhangxian, Chengxian, Wenxian and other places in Gansu, and also produced in Yunnan, Sichuan, Shaanxi, Hubei and other provinces. It is mainly cultivated. (2) Processing at origin: dug up in late autumn, the fibrous roots and sand and soil are removed, and after the moisture has evaporated slightly, it is tied into small bundles, placed on racks, and slowly smoked dry with smoke and fire. (3) Characteristics: slightly cylindrical, with 3-5 or more branch roots at the lower part, 15-25 cm long. The surface is yellowish-brown to brownish-brown, with longitudinal wrinkles and transversely elongated lenticels. The root head (gui head) is 1.5-4 cm in diameter, with

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.

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

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

How to treat cotton cancer? Timely prevention and control is key
Fusarium wilt and Verticillium wilt are called "cotton cancer" by cotton farmers. At present, continuous high temperature and rain for many days make the cotton field look like "the situation is excellent"; but during field investigation, the author found that plants with Fusarium wilt and Verticillium wilt still exist in the cotton field, with dry edges on the lower leaves extending inward and showing chlorosis and yellowing, and the whole plant growing poorly and being relatively short. Cotton farmers are especially reminded not to take it lightly. 1. Disease characteristics. Fusarium wilt and Verticillium wilt mainly occur due to factors such as soil-borne bacteria (Fusarium wilt pathogen can survive in soil for 7-10 years, Verticillium wilt pathogen

Timely Control of the Rice Leaf Roller Is Essential and Cannot Be Delayed
The rice leaf roller is one of the major rice pests in our province. Its larvae damage the leaves, turning rice leaves into a mass of withered white. Especially when it attacks at the booting or heading stage, it will cause a sharp decline in rice yield. This pest has seven generations a year, and the second-generation larvae are the most numerous and cause the most serious damage to early rice. If control is not timely, it will break out in a major outbreak during the heading period, causing incalculable losses. For forecasting the rice leaf roller, the appropriate control timing should be determined based on the forecast of the occurrence period. Based on past conditions, investigation should begin 4 days after the peak of the moth flight
