Description

Technical Field

[0001] The invention relates to the technical field of cotton breeding, in particular to a seedling cultivation box for constant temperature cotton breeding and a use method thereof. Background Art

[0002] Cotton belongs to the genus Gossypium of the Malvaceae family and is a cross-pollinated plant. Cotton is the only crop that produces fiber from seeds, which is also its most basic, prominent and important characteristic. Cotton is an important agricultural product and textile raw material in my country. It is an important material related to the national economy and people's livelihood, and occupies a very important position in the development of the national economy. Improving cotton lint yield, improving cotton fiber quality, and improving cotton's disease and insect resistance are important goals of cotton breeding in my country at present. Using different cotton germplasm resources as materials, through genetic improvement, cotton varieties with high production potential, excellent fiber quality or certain special traits, and suitable for planting in certain areas are selected. Cotton breeding plays an important role in increasing cotton yield, improving quality, enhancing stress resistance, expanding planting areas and improving cultivation and management techniques.

[0003] Xinjiang is located in the hinterland of the Eurasian continent. It has unique climatic conditions and rich light and heat resources, which provide environmental advantages for the development of the cotton industry. Cotton is also one of the important cash crops in Xinjiang. Cotton production occupies an important position in the economy of Xinjiang and has become an irreplaceable cash crop and an important pillar industry. Xinjiang's cotton planting area, output, and yield are all among the best in the country. As an important production base of high-quality cotton in my country, it plays a pivotal leading role in the country in terms of production scale and production efficiency, and its dominant position is irreplaceable. Since the 1990s, Xinjiang's cotton production has developed rapidly. The planting area, total output, yield and output have ranked first among all provinces and regions in the country for 26 consecutive years, making it the largest high-quality cotton production and export base in the country. In 2021, Xinjiang's cotton area accounted for 82.8% of the country, and the lint output accounted for 89.5% of the country's total cotton output. The cotton industry in Xinjiang shoulders the important tasks of ensuring the safety of cotton production in my country, meeting the needs of the cotton textile industry, promoting the economic development of Xinjiang, maintaining stability in the border areas, promoting development to the south, and realizing rural revitalization. Therefore, strengthening and optimizing the cotton industry in Xinjiang is of great significance to the sustainable development of cotton production in Xinjiang.

[0004] The cultivation of cotton seedlings is to first plant the cotton seedlings in a rice seedling tray. When the cotton seedlings grow to a certain size, they are promptly moved to other containers for planting. The environment for cotton seedling cultivation is very important. When transplanting, special attention should be paid to not damaging the root system of the cotton seedlings. Before transplanting, the soil or substrate should be fully watered, and then transplanted. In this way, the cotton seedlings will survive quickly after transplanting. Shading should also be paid attention to during the seedling acclimatization period after transplanting.

[0005] Temperature control engineering in the process of cotton seedling cultivation is a means of rapid growth, high quality and high yield of agricultural organisms, and is an important symbol of agricultural modernization. Seed vigor is an agronomic trait that agricultural breeders pay more attention to, which is closely related to crop growth potential, yield, quality, etc. The existing seedling cultivation box cannot adjust the temperature and soil moisture of the environment, resulting in a lower survival rate of cotton seedlings during the cotton seedling cultivation process, causing the problem of increased production costs, and the internal conditions of the seedling cultivation box are usually manually regulated, resulting in the phenomenon of unsuitable environment for cotton seedling cultivation, affecting the efficiency of cotton seedling growth.
