First, protect the root system. As the temperature drops gradually, the tea tree will be dormant, and the nutrients accumulated in the aboveground part will begin to transfer to the root system, which will accumulate nutrients for sprouting in the following spring. Improper farming at this time, the more the root cause, will result in reduced production. At this time cultivating fertilization should be based on the protection of the root system, to the principle of not hurting the roots or less wounds, cultivator when the line can be slightly deep, both sides should be shallow, fertilization ditch in the line, but also can be fertilized alternately, after application Cover the soil immediately to prevent freezing damage. Second, apply more organic fertilizer. Practice has proved that the use of organic fertilizers such as rapeseed cake, pig cow dung and rabbit manure in tea gardens is a key measure to improve the yield and quality of tea, especially famous tea. The use of basal fat is more important. It can improve the aroma, color and taste of famous teas. . The demonstration area of ​​the provincial tea plantation breeding and the Changzhan Reservoir Management Tea Plantation in Xinchang is only 200 meters above sea level. However, the produced Long Buddha Longjing has a color and fragrance that is higher than that of alpine tea, and is recognized as a Teyou Longjing tea. The important one is to pay attention to vegetable cakes every year, such as 250 kg of rapeseed cakes in Mushi. At present, fertilizers that have not yet been fertilized should be treated with organic fertilizers, compound fertilizers, and nitrogen fertilizers such as urea and ammonium bicarbonate.
