A letter from Yan Zuzhi, Shuanghe Broadcasting Station, Enshi City, Hubei Province asked: Many local vegetable farmers asked them whether they could develop tomatoes at high altitudes of 1,500 meters above sea level. Because they have no experience, they asked the newspaper for help and hope to introduce some tomato cultivation techniques! A: Comrade Yan Zuzhi, hello! On May 23, I received a letter asking if the mountain can develop tomatoes? For the hot and humid regions in the middle and lower reaches of the Yangtze River, only high mountain areas can produce good tomatoes. To develop the commodity production of tomatoes, in addition to considering the basic facilities such as water, electricity and transportation, we must also understand the climate conditions (temperature - average daily temperature, average temperature, average frost period, absolute frost period; rainfall - annual precipitation, Monthly precipitation; sunshine - sunshine rate), soil conditions (suitable sandy loam for tomatoes), production level (labor, organic fertilizer, chemical fertilizer supply status, technical level, etc.) and market conditions (with or without market, unit price level, local residents eating habits , can be shipped outside, etc.). It is clear that these basic conditions can be used to formulate plans for the production of tomatoes (including cultivation season, cultivation methods, varieties, time and method of planting, methods of stent pruning, prevention and control of diseases and pests, methods of collection and transportation, etc.). Tomatoes in the new area, such as suitable climatic conditions and proper cultivation, pests and diseases will not be too heavy, but with the extension of the cultivation period, pests and diseases will become more and more important. The new district shall adopt preventive measures such as crop rotation, clean gardens, sedation and killing, and strengthening management to reduce or eliminate the occurrence and spread of certain pests and diseases so as to achieve the purpose of using less or no pesticide, ensuring the safety and quality of products, reducing costs, and improving profits. Since the cultivation of tomatoes is already common, detailed techniques have not been elaborated. If you want to learn more details, you can call for further exchanges.
