本文结合陕西太白县高山生菜种植生产实践，从产地环境要求、品种选择、精细整地、育苗移栽等方面系统分析了高山生菜的标准化高效栽培技术。产地环境要求方面，选择海拔600 m以上的高山冷凉地区，要求地块地势高燥且开阔平坦；品种选择方面，选择性状稳定、优质、高产、适应能力和抗逆性强、耐贮运、适宜机械化种植的品种，如罗马生菜、意大利生菜等；精细整地方面，及时清园，选用合适的机械深翻土壤，采用基肥+追肥模式；种子处理方面，在播种前，用50%多菌灵可湿性粉剂等进行拌种，气温高于25 ℃时种子应进行低温催芽处理；育苗移栽方面，采用穴盘漂浮育苗、塑料穴盘冷床基质水培育苗方式，选择疏松、保水透气性好且无病菌的基质，采用人工或精量播种器械精准点种，点种量在1～2粒/穴，点种深度0.5～1.0 cm；定植管理方面，早春茬在5 cm土层温度稳定在10 ℃以上时，选择晴天早晨、下午或阴天定植；苗期管理方面，根据不同生长阶段的生菜生长情况，合理浇水施肥；病虫害防治方面，及时彻底清除田间地头病残株、杂草等，设置防虫网、利用瓢虫等害虫天敌种群、喷施合适的化学药剂防治病虫害；适时采收方面，当生菜叶片饱满、嫩绿且无病斑、干叶时，选择清晨或日落前后及时采收；农业生产废弃物处理方面，集中统一处理农用残膜、农药包装废弃物，循环利用肥料包装废弃物。本文为高山生菜产业高质量发展提供参考。

Based on the practice of highland lettuce planting in Taibai County, Shaanxi Province, the standardized and efficient cultivation technology of highland lettuce were systematically analyzed from the aspects of environment requirements, variety selection, fine land preparation, seedling transplanting and so on. In terms of the environmental requirements for the production area, a cold and cool highland region with an altitude of over 600 m is selected. The terrain of the plot should be high, dry, open and flat. In terms of variety selection, choose varieties with stable traits, high quality, high yield, strong adaptability and stress resistance, good storage and transportation properties, and suitable for mechanized planting, such as Romaine lettuce, Italian lettuce, etc. In terms of meticulous land preparation, the garden should be cleared in a timely manner, appropriate mechanical deep ploughing of the soil should be selected, and a base fertilizer + top dressing model should be adopted. In terms of seed treatment, before sowing, mix the seeds with 50% wettable powder of carbendazim, etc. When the temperature is above 25 ℃, the seeds should undergo low-temperature germination treatment. In terms of seedling transplanting, floating seedling raising in trays and hydroponic seedling raising on plastic tray cold bed substrates are adopted. Substrates that are loose, have good water retention and air permeability, and are free of pathogens are selected. Precise seeding should be carried out either manually or with precision seeding equipment. The seeding amount should be 1 to 2 seeds per hole, and the seeding depth should be 0.5 to 1.0 cm. In terms of planting management, for early spring crops, when the temperature in the 5 cm soil layer stabilizes above 10 ℃, it is advisable to plant in the morning or afternoon on a sunny day or on a cloudy day. In terms of seedling management, water and fertilize reasonably according to the growth conditions of lettuce at different growth stages. In terms of pest and disease control, it is necessary to promptly and thoroughly remove diseased and dead plants and weeds in the fields, set up insect-proof nets, utilize natural enemy populations of pests such as ladybugs, and spray appropriate chemical agents to control pests and diseases. In terms of timely harvesting, when the leaves of lettuce are plump, tender green and free of disease spots and dry leaves, it is advisable to harvest them in the early morning or around sunset. In terms of agricultural production waste treatment, centralized and unified treatment of agricultural residual films and pesticide packaging waste is carried out, and fertilizer packaging waste is recycled.
