Celery is a semi-cold vegetable with weak drought resistance and a cool, humid climate. The optimal temperature for seed germination is 15-20°C. If the temperature is higher than 25°C, the germination will be postponed and the germination rate will be reduced. The optimum temperature for seedling growth will be 18--20°C. If the temperature is higher than 27°C, the growth will be hindered and easy to occur. Old seedlings and other phenomena. However, autumn and winter wolfberry celery seedlings are in the hot season of June-August. Because of the high temperature (generally between 30--40°C), strong sunshine and vulnerability to drought, shading, cooling and moisturizing must be adopted. The cost is high and the effect is not very good. For this reason, the author changed it to raise the seedlings in a cool climate and high humidity in the air, then transport them to the low mountains for transplanting in the cool autumn. Because of the suitable nursery environment, the celery not only emerged faster, grew more prosperously, had fewer pests and diseases, but also cultivated celery. The seedlings are very robust and the cost of raising seedlings is significantly reduced. The specific method is: In the mountains above 800 meters above sea level, choose convenient transportation, soil fertility, less weeds, water source guarantee and convenient management of land, plough fertilization, picking net grass roots after 1.5 meters wide. The glutinous rice shall be thoroughly drenched with water, and after the complete infiltration of the clear water, soaking the celery seeds mixed with the germinating seeds and soaking the seeds in the cultivar shall be uniformly planted on the glutinous rice noodles. The seeds shall be tightly covered with sifting fine soil, and a layer of reed leaves shall be covered. Or other branches, to ensure that there are flowers in the sun. If pests are found, use crystals of trichlorfon and stir-fry wheat bran to soak in and around the surface. After celery Qimiao, promptly remove the surface cover material, pay attention to spray water to keep the surface moist. About 20 days after emergence, the first time the seedlings were weeding, and then the seedlings were weeding once every 7-10 days to keep the noodles with grass and seedlings evenly spaced. After the three-leaf stage of the seedlings, the fertilization of the diluted fertilized water was started, and fertilizer was applied once every 5-7 days. Before transplanting seedlings, pay attention to the appropriate control of water and fertilizer supply, and promote the growth of seedlings to be robust and solid. When transplanting, the seedlings should be pulled up with soil as much as possible, neatly discharged into cartons with vent holes, and quickly transported to low-hill colonization.
