Abstract: The field experiment was conducted in 2019 main cropping season at two locations using simple lattice design to evaluate 49 field pea genotypes including nine released varieties for generating information on genotypic and phenotypic association among yield contributing traits and with grain yield, and to study their path analysis on grain yield. Positive and significant genotypic correlation observed between grain yield with plant height (rg=0.67), seeds per pod (rg=0.45), days to maturity (rg=0.41) and pods per plant (rg=0.33) for combined analysis. The association among most of traits demonstrated higher genotypic correlations than corresponding phenotypic correlations that; indicated the prevalence of genetic variation in expression of the traits. Genotypic path analysis also indicated that plant height (0.746) exerted the maximum positive direct effect on grain yield followed by stand count at harvest (0.443), 1000 seed weight (0.372), seeds per pod (0.214), pods per plant (0.213), and days to maturity (0.013). Therefore; selection for traits such as plant height, pods per plant, seeds per pod and days to maturity could improve grain yield in field pea.

Abstract: China is an large agricultural country, which grain output has been among the highest in the world. In recent years, agricultural waste caused by high grain yield has attracted more and more attention. As one of the main agricultural waste, the total straw amount of China has reached 870 million tons by year of 2019, and the straw utilization amount has reached 730 million tons, which indicates enormous strains on the environment. In China, straw burning is strictly forbidden by local governments, so it is mostly utilized by returning the field, making manure, fodder, fuel, base stock or raw material. The five utilization ways separately make up 61.3%, 5.3%, 14.9%, 10.3%, 0.8%, 1.0% of the total share. To promote better utilization of straw, this paper made a comprehensive review of the main utilization technologies in China by the method of literature research. According to the research, the utilization technologies of straw mainly include corn straw deep tillage technology, cotton straw deep-turning technology, wheat straw mulching-corn straw rotating tillage technology, less no-tillage straw mulching technology, rice-wheat (or rape) straw crushing returning rotary tillage technology, straw rapid maturing, straw-forage-fertilizer planting and raising combination technology, straw-biogas-fertilizer energy ecological technology, straw-bacteria-fertilizer substrate utilization technology, straw-carbon-fertilizer returning and soil improvement technology. All these utilization have promoted the rapid development of the comprehensive utilization of straw in China, and enlightened further development of straw utilization.

Abstract: Carbon Storage Estimation of wood products is one of the important directions of international climate change. As a building material of ecological sustainable development, wood structure building has many advantages, and its performance is better than other structures in many aspects. Forest products are sustainable. If forest products come from sustainably managed forests, and if they follow some principles of sustainable management, then wood, as a material and a product of wood products in daily life, is far more sustainable than other materials, from buildings to furniture. In this paper, the wood structure building is briefly introduced. On this basis, the role of wood structure product carbon flow in forest carbon storage and the impact on the environment are elaborated, which points out the direction for the development of related research in the future. The results are as follows: wood has little impact on climate in the whole life cycle and beyond, and its carbon emission in the life cycle is far lower than that of traditional building materials. The performance of wood structure building constructed with wood building materials is better than that of reinforced concrete structure in terms of energy saving, earthquake resistance, environmental protection and durability. The external ecological environment has a certain positive impact, promoting the sustainable development of society and the harmonious coexistence of man and nature.

Abstract: Forest has the function of nourishing body and mind, promoting health, enhancing human immunity, which is of great significance to improve health index. Forest health care can give full play to the advantages of forest landscape, environment, space and culture, and extend forest functions. It is a new industry integrating forestry, health services, tourism and leisure industry, and is a new trend of sustainable development of forestry. Ecological poverty alleviation is a kind of poverty alleviation mode which combines ecological protection with poverty alleviation and development. Through the implementation of major ecological engineering construction, increasing ecological compensation, vigorously developing ecological industry, and innovating ecological poverty alleviation methods, the support for poverty-stricken areas and the poor population should be strengthened, so as to achieve the poverty alleviation mode of coordinating poverty alleviation development and ecological protection, and promoting poverty alleviation and prosperity with sustainable development, and finally achieve the goal of poverty alleviation and ecological civilization construction Win. Forest health care is a new way of ecological poverty alleviation. Forest health care can give full play to the resource advantages of mountain areas and drive mountain farmers to get rid of poverty and become rich. It is an effective way of forestry reform, forestry innovation and forestry development, and an inevitable trend to promote green prosperity and poverty alleviation. Based on the model of forest health care, this paper deeply analyzes the development status of forest health industry, discusses the measures to optimize the path of ecological poverty alleviation, and puts forward suggestions on the long-term development mechanism of organic combination of forest health industry development and ecological poverty alleviation work.
