Changyang Alpine vegetable has a base area of 1.987 hectares, a planting area of 3.33 hectares, and an annual output of 1.5 million tons. It is the first county of Alpine vegetables in China, with an annual output value of nearly 2 billion yuan. Alpine vegetables have become a pillar industry for Changyang alpine area to get rid of poverty and increase income. The main varieties are Chinese cabbage, white radish, cabbage, pepper, tomato, etc. there are a small number of fine vegetable varieties such as fruit cucumber, lettuce, celery, baby cabbage, coriander, etc., which are far from meeting the consumption demand of the middle and lower reaches of the Yangtze River in summer and Autumn. The large area of the main varieties leads to great pressure on fresh sales in the market. How to further adjust the variety structure, enrich the vegetable production varieties, and meet the diversified needs of consumers, It has become a supply side contradiction for us to make Alpine vegetables an industry for alpine farmers to steadily increase their income and become rich. Rapeseed is a traditional crop in China. 1 it is mainly used for edible oil. In recent years, many scientific and technological personnel have shifted the research direction of rapeseed from traditional edible oil to two-way research on oil extraction and rapeseed moss, and even to honey and fertilizer utilization. In this experiment, a new rape variety Dadi 1992 was introduced, and experiments were carried out at different altitudes and sowing dates in order to obtain higher rape moss yield, enrich Alpine vegetable cultivar 3, and fill the gap in autumn vegetable market.
