How can large-scale rabbit farms prevent disease? These new viewpoints are worth reading
Play down treatment, optimize the rabbit herd. Traditional rabbit farming emphasizes treatment over prevention, often turning the rabbit farm into a sanatorium for sick rabbits. To change this situation, some experts have proposed the "five no-treatment" rule for sick rabbits: do not treat rabbits that cannot be cured, do not treat rabbits whose treatment cost is high, do not treat rabbits whose treatment is time-consuming and labor-intensive, do not treat rabbits whose economic value after recovery is not high, and do not treat rabbits that are highly contagious and highly harmful. Practice has proved that after rabbit farms implemented this system, the health status of the rabbit herd improved markedly, virulent infectious diseases were effectively controlled

Management Techniques for Large Suli Pear Trees After Transplanting
1. In the winter of the year of transplanting, the old scaly bark on the trunk and main branches must be thoroughly scraped off, and the scraped debris should be collected and burned. After scraping, the trunk or large branches should be coated with whitewash or sprayed with 5-degree lime sulfur mixture. For disease spots such as rot on the branches, use a knife to scrape the disease spots clean, then apply 40% asomate 50-fold solution. During the growing season, strengthen pest and disease control to preserve leaves and promote branch growth. 2. After sawing off large branches of transplanted large trees, smooth the wounds and apply 800-fold carbendazim solution for protection to prevent infection. Larger wounds should also be sealed with clay, then wrapped tightly with plastic film.

How good is the Super Large Grain King rice variety?
Zhezao 15 is a super-high-yield early indica rice new line developed by mutagenesis treatment using the super-high-yield genetic advantage of "Zhe 18500". After multi-point trial planting as early rice by the Zhejiang Academy of Agricultural Sciences, the yield generally reaches more than 600 kg per 667 sq m (1 mu). The characteristics and advantages of Zhezao 15 are introduced as follows: 1. Extremely strong tillering ability, low seed requirement. The effective tillers per plant can reach 12-15, and 1 kg of seed per 667 sq m of field is sufficient. 2. Cold tolerance at the seedling stage, disease resistance at the later stage. Strong cold tolerance at the seedling stage, so sowing can be appropriately advanced

Detailed explanation of large icefish processing technology, mastering the key operation points
Large icefish, also called noodle fish, was originally widely distributed in the main stream and affiliated lakes of the middle and lower reaches of the Yangtze River. Its flesh is tender and delicious, rich in nutrients, and eating it gives a special fresh cucumber-like aroma. Large icefish generally has a body length of about 20 cm, with no bones or spines, and is a small valuable fish with very high economic value, deeply welcomed in domestic and international markets. From 1985 to the early 1990s, the reservoir transplantation and propagation of large icefish was carried out comprehensively across our country and achieved success. Its distribution area is continuously expanding, and output is increasing day by day. How to do a good job in

Artificial propagation techniques for large icefish: Practical experience from Hongshan Reservoir
Hongshan Reservoir is located in the lower reaches of the Laoha River in the northeast of Chifeng City. It is a large plain-type reservoir integrating flood control, irrigation and aquaculture, with a catchment area of 24,500 sq km and a total storage capacity of 2.56 billion cubic meters. The reservoir's fish-farming area ranges from 80,000 mu to 130,000 mu between the dry season and the wet season. The reservoir introduced fertilized eggs of large icefish in 1995, and the catch reached 2.5 kg/mu in 1998. In the following 2 years the yield declined somewhat, but in recent years, thanks to relatively well-developed propagation management measures, the resource has gradually recovered.

Detailed Explanation of Key Technical Points for Transplanting Large Schrenk Spruce Seedlings
Schrenk spruce (Picea schrenkiana) is a tree species unique to the Tianshan mountain forests. It is an evergreen tree with needle-shaped, slightly curved leaves. The cones are oblong-elliptical and brown. Seedlings are shade-tolerant but intolerant of scorching sun, frost, and drought. They typically regenerate well under broadleaf forests and grow vigorously under moderately moist conditions and full light. The Schrenk spruce has a narrow, elongated crown, a thick, straight trunk, and a rugged, upright form. With the improvement of the social economy and people's living standards, urban greening construction has received increasing attention. With its graceful, upright form and evergreen lush foliage, the Schrenk spruce has become a favorite among greening trees.

Detailed Explanation of Key Techniques for Transplanting Large Spruce Saplings
Seedling transplanting is one of the main greening methods for urban streets, landscaping, and the construction of ecologically prosperous villages and towns. In recent years, the transplanting of large saplings has become particularly important because it takes effect quickly, achieves remarkable results, and is not easily damaged by human activity, and it has gained widespread recognition. However, large sapling transplanting is also constrained by factors such as high cost, large investment, and low survival rates. Therefore, mastering transplanting techniques according to the biological characteristics of different tree species, improving survival rates, and increasing green areas play a positive role in promoting ecological civilization construction.

How to carry out maintenance and management of large spruce saplings after transplanting
Large spruce saplings over 40 years old have weak regeneration capacity after transplanting. To ensure their survival, maintenance and management of transplanted large spruce saplings is especially important. As the taste of urban construction keeps improving, the scale and grade of urban greening and beautification also rise accordingly, requiring the greening and beautification effect to be shown within a relatively short time, so a considerable number of tall trees need to be transplanted. Hebei Saihanba Mechanical Forest Farm, as the largest larch timber forest base in North China, also shoulders the mission of windbreak, sand fixation and water conservation, and for many years has provided
