Detailed explanation of plastic greenhouse cultivation techniques for large-fruited sweet carambola
Large-fruited sweet carambola is a tropical and subtropical evergreen fruit tree that grows fast, bears fruit early, flowers and fruits multiple times a year, and produces excellent fruit that is crisp and juicy, making it deeply loved by people. However, for a long time, carambola cultivation has been managed extensively, with low per-unit yield, poor quality, and relatively weak market competitiveness and economic benefits. Therefore, in April 2001, our institute began cultivating large-fruited sweet carambola in plastic greenhouses, with an area of 0.43 hm2. Fruit was set in the same year of planting. The yield per hectare was 5700 kg in the first year, 27000 kg in the second year, and 6

Detailed Explanation of Key Techniques for Establishing a Seed Production Forest with Large Korean Pine Seedlings
Korean pine (Pinus koraiensis), of the family Pinaceae and genus Pinus, is an evergreen coniferous tree. It is mainly distributed in the Greater Khingan Mountains and Changbai Mountain areas of China, where its Korean pine forests form the climax community of the region, playing an enormous social, ecological and economic role. In the early years of the founding of New China, to meet the needs of economic construction, Korean pine timber was excessively logged, causing a massive decline in Korean pine trees; at present, only about 5 million mature Korean pine trees remain. Therefore, establishing Korean pine seed production forests on a large scale, rapidly and with high quality is of great

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

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.

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.

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.
