What to Do About Low Hatch Rates in Female Turtles? Cause Analysis and Solutions
Artificial turtle farming has sprung up in many places in recent years, especially as the soft-shelled turtle market has flattened while the turtle market has held firm, prompting many soft-shelled turtle farmers to switch to turtles. But farmers have found that although some female turtles lay a good number of eggs, the fertilization rate is not high and the hatch rate is low, especially with eggs from turtles at their first laying age, where the fertilization rate is even lower. Many people assume the female turtle is the problem, little realizing that the cause does not lie with the female turtle at all, but is mainly related to factors in the male turtle itself. Through practice, people have found that in nature many animals show differences in the timing of sexual development

What about Xidou 3, a superior soybean variety for both grain and vegetable use?
I. Yield Performance In 1997, the Chongqing Soil and Fertilizer Station conducted a variety comparison trial in Yubei District, Banan District and Jiangjin City, where the average yield across the 3 trial sites was 146.4 kg/667 sq m, ranking first in the trial. In 1998, the Tongnan County Soil and Fertilizer Station conducted a large-plot comparative trial of Xidou 3 and Yudou No. 1, and the results showed that Xidou 3 had an actual yield of 236 kg per 667 sq m, a 14.6% increase over Yudou No. 1. Through years of multi-site trials, demonstrations, and promotion practices in various places, Xidou 3 has shown that it is currently a new ideal soybean variety for both grain and vegetable use in the southwest region, with high yield potential,

What medicine is used for Newcastle disease? Treat with Xinbiduo.
In recent years, farmers' awareness of management and of disease prevention and healthcare has improved greatly compared with before. Many farmers have begun to use oil-emulsion vaccines for immunization, to strengthen disinfection, and to use healthcare drugs such as probiotics, which have indeed played a fairly large role in disease control in production. However, in recent years the occurrence of chicken immunosuppressive diseases has also been equally serious. Immunization failure makes chickens very difficult to raise, and various diseases break out repeatedly, bringing huge losses to the chicken farming industry. According to statistics, in recent years the greatest harm to the chicken farming industry

Method for building a greenhouse for raising Schisandra chinensis seedlings in nutritional pots
Build a plastic greenhouse of a suitable size according to the number of seedlings to be raised (or use a solar greenhouse). For general vegetable (cucumber) cultivation, a plastic greenhouse is used, with a width of about 12 m, a length of 80-100 m per greenhouse, and a height of more than 2 m, with doors at the front and rear, welded from steel bars. A small shed can also be set up, using materials such as steel bars, bamboo strips or wooden poles. Building a simple shed costs little but has a short service life.

What disinfectants are commonly used in snake farms?
"Disinfect the snake farm often, and with diligent care the snakes stay disease-free." For snake farms (and keepers), "prevention is better than cure" is an eternal rule. Especially under captive breeding and home propagation conditions, routine chemical disinfection must be kept up, otherwise a trivial matter can "brew" into a big problem, and by then it will be a bit late to try to salvage the situation. Disinfectants now on the market come in a confusing array of types, but snake farms (and keepers) must not blindly misuse disinfectants that are irritating, smelly or corrosive, such as caustic soda, Lysol, 84 disinfectant, formalin (formaldehyde)

Analysis of Issues in the Formulation and Use of Complete Feed for Ussuri Raccoon Dogs
The raccoon dog is an animal endemic to East Asia, mainly found in China, Russia, Korea, Japan, Mongolia and other countries, and is divided into many subspecies. The Ussuri raccoon dog is mainly distributed in China's Heilongjiang Province, the eastern and southeastern regions of Jilin Province, and northeastern Korea. At present, the vast majority of raccoon dogs bred in captivity in China are Ussuri raccoon dogs originating from Heilongjiang Province. The raccoon dog is one of the fur-bearing animals with high economic value. Compared with foxes and mink, it has the advantages of bearing more cubs, a high survival rate, being easy to raise, and having a stable market; therefore, in recent years the number of raccoon dogs raised in China has steadily increased year by year, with good momentum

What to Do About Severe Fruit Russeting in 'Hwangkeum' Pears? Causes and Control Measures
1. Causes of severe russeting in bagged fruit 1.1 Improper pesticide use during the young fruit stage. 'Hwangkeum' pears are sensitive to pesticides during the young fruit stage, which is very different from the management of 'Yali' pears. If the pesticide application procedures for 'Yali' pears are followed, russeting is bound to occur. 1.2 Orchard crowding, excessive canopy branch density, and poor ventilation and light penetration lead to russeting. At present, most pear orchards in our area are high-density orchards developed in recent years, with spacing mostly 4 m x 4 m or 3 m x 4 m, and trees about 15 years old. In pursuit of early bearing and high yield, the high-yielding tree form used for 'Yali' pears has been adopted, resulting in a top-heavy tree with excessive retained branches, which makes the orchard air humidity, especially inside the canopy, too high and lasting too long. In this humid environment, physiological factors and the synergistic effect of pesticide residues on the fruit surface aggravate russeting in bagged 'Hwangkeum' pears.

What to Do When Chicken Immunization Is Ineffective? Cause Analysis and Countermeasures
Now many chicken farmers generally report the following problems: (1) The flock is fine when not vaccinated, but as soon as they are vaccinated, the flock breaks out with disease. (2) Sometimes the flock breaks out with disease before they have even been vaccinated. (3) No matter what measures are taken, the immune effect of the vaccine is always poor. Why do these problems occur? The reason is that the chickens' immune organs have been damaged. After the immune organs of chickens are damaged, the body's resistance to bacterial and viral infections declines, and the flock is very prone to large outbreaks of various epidemic diseases, bringing huge economic losses to the poultry industry. So

Why do continuous and alternating soybean cropping reduce yields? Cause analysis and countermeasures
With China's accession to the WTO and the opening-up policies of the grain market, the problem of continuous and alternating soybean cropping has become increasingly serious, and the yield reduction increases as the number of consecutive cropping years rises. According to surveys and research, alternating cropping reduces yield by 6.1%, one year of continuous cropping by 9.9%, two years of continuous cropping by 13.8%, and three years of continuous cropping by 19.0%. Moreover, in continuous and alternating cropping soybeans, the 100-seed weight decreases, the rate of diseased seeds and insect-damaged seeds increases, and commercial quality drops significantly. With long-term continuous cropping of more than 3 years, the protein content of soybeans increases markedly while the fat content decreases markedly.
