Studies have shown that the organic products contain more iron, magnesium, calcium and other trace elements and vitamins C, and lower contents of heavy metals and carcinogenic nitrates. In recent years, organic rice wins the fa- vor of consumers due to its pure natural and pollution-free advantages. Based on the planting area selection, organic rice variety screening, fertilization, control of dis- eases and insect pests and harvesting, this article specifically discussed the cultiva- tion techniques of organic rice and developed the cultivation technology regulation of organic rice in Yellow Rive irrigated area of Ningxia, in order to lay the foundation for speeding up the development of organic rice industry and establishing highly standardized and normalized organic rice production base, thereby promoting the standardization of organic rice production.展开更多

Wheat is the main crop planted in our province, and its own yield and quality have always been concerned by people. Plant protection technology plays an important role in wheat high-yield cultivation, and can also promote the construction and development of modern agriculture. Therefore, the relevant units should pay more attention to the plant protection technology, have a comprehensive understanding of the specific content and process of the technology, and work out an appropriate technology implementation plan based on the actual situation, so as to improve the effectiveness of the technology operation and further ensure the quality and quantity of wheat production.展开更多

The results showed that with transplanting periods of March 5-March 15, and planting space of 120 cmx（50-60） cm, agronomic and economic characters of tobaccos showed insignificant differences. Specifically, plant height was growing upon the number of left leaf and fertilizer amount; tobacco yield and output value kept increasing upon fertilizer, and both reached maximums with pure N at 195 kg/hm^2, showing significant differences with the treatment of pure N at 135 kg/hm^2; the number of left leaf had the least effects on agronomic and economic characters of tobaccos. The research indicated that highly-qualified HQ No.1 can be produced, given that tobaccos are transplanted during March 10-March 15, planting density of 15 000-16 500 seedlings/hm^2, the number of left leaves of 22-24 leaves per seedling, and pure N of 150-165 kg/hm^2 in Hengyang.展开更多

Rice is the main food crop in China and plays an important role in Chinas agricultural production. Whether rice is planted green or not will have a significant impact on peoples health, and green rice planting will gradually become the future development trend of rice production. At present, the green ecological technology is developing rapidly in China, and the rice planting technology in China is constantly improving and perfecting, which can not only realize the greening and scale of rice production, but also improve the quality of rice planting and realize the sustainable development and progress of Chinas agriculture. In this paper, taking Donglan County as the main research background, the cultivation points and popularization measures of rice green high-yield technology are analyzed, which will provide theoretical basis for further popularization of rice green high-yield technology.展开更多

The traditional mode of animal husbandry will lead to overgrazing. The ecological environment of grassland will not only be seriously damaged, but also gradually deteriorate. With the passage of time, the quality of the original high-quality forage grass will drop significantly, which will also provide convenient conditions for the growth of other harmful weeds. Therefore, in the process of development, the traditional mode will be changed, and the structure of animal husbandry and breeding industry will be adjusted. Artificial grass planting will actively carry out the processing of scientifically modulated grass, so that better silk products can be produced, and the growth and development needs of animals can be met. Taking Yulin city in Shaanxi province as an example, this paper discussed and analyzed the technology of forage cultivation and forage processing.展开更多

文摘In order to enhance the yield and quality of cashew,it is essential to implement high-yield cultivation techniques effectively throughout the production process.Additionally,pest control measures should be employed to provide technical support for the industrialized development of cashew.
文摘With the rapid development of agricultural industry, people have higher and higher requirements for the safety and quality of agricultural products, and rice, as one of the traditional food crops in China, has also received extensive attention. Rice is the main food crop in China and plays an important role in Chinas agricultural production. Whether rice is planted green or not will have a significant impact on peoples health, and green rice planting will gradually become the future development trend of rice production. At present, the green ecological technology is developing rapidly in China, and the rice planting technology in China is constantly improving and perfecting, which can not only realize the greening and scale of rice production, but also improve the quality of rice planting and realize the sustainable development and progress of Chinas agriculture. In this paper, taking Donglan County as the main research background, the cultivation points and popularization measures of rice green high-yield technology are analyzed, which will provide theoretical basis for further popularization of rice green high-yield technology.
文摘Natural grassland is an important grazing place for farmers. The traditional mode of animal husbandry will lead to overgrazing. The ecological environment of grassland will not only be seriously damaged, but also gradually deteriorate. With the passage of time, the quality of the original high-quality forage grass will drop significantly, which will also provide convenient conditions for the growth of other harmful weeds. Therefore, in the process of development, the traditional mode will be changed, and the structure of animal husbandry and breeding industry will be adjusted. Artificial grass planting will actively carry out the processing of scientifically modulated grass, so that better silk products can be produced, and the growth and development needs of animals can be met. Taking Yulin city in Shaanxi province as an example, this paper discussed and analyzed the technology of forage cultivation and forage processing.
文摘Directing at the characteristics of coastal mudfiat saline and alkaline land, the yield of salt-tolerant Spartina and rice could reach 5 925-8 280 kg/hm^2 by the techniques of land and water resource utilization, farming improvement, construction of matched water system, seed selection and treatment, water direct seeding, seedling raising on seedbed, field transplanting, weeding, nutrient and water management, and disease and pest control, providing a scientific basis for the cultivation of Spartina and Rice in coast mudflat.
文摘This paper focuses on the application of AIGC(Artificial Intelligence Generated Content)technology in higher vocational education teaching modes.It deeply explores the significant meaning of AIGC in empowering higher vocational education,and analyzes the existing problems when AIGC technology is applied to such teaching modes,covering aspects like technology application,teaching staff,students’adaptability,and educational management.Meanwhile,it puts forward targeted and effective paths for AIGC technology to empower higher vocational education teaching modes,including optimizing technology application,strengthening teacher training,improving students’literacy,and perfecting educational management.The paper aims to promote the in-depth integration of AIGC technology and higher vocational education,realize the innovation and high-quality development of higher vocational education teaching modes,and provide theoretical references and practical guidance for cultivating high-quality technical and skilled talents who meet the needs of the new era.
