The cultivating and fertilizing tea plantations are harvested in the spring, summer and autumn, with intertwining knots and weeds growing around the roots. We should carry out cultivating and weeding in the winter to loosen the soil. The cultivators are generally 20-30 cm deep and 15-20 cm long for digging trenches. Combined with the reuse of basal fertilizers, they should be farmyard fertilizers, which is conducive to heat preservation, early germination and the improvement of tea quality. It is required to apply more than 50 tons of earth fertilizer per mu, about 100 kg of cake fat, 40 kg of phosphate fertilizer, 30 kg of potash, and 30 kg of available nitrogen fertilizer. Fertilizers should be applied in layers, with ground-layered compost under 20 cm, cake-fertilizer in layers of 10-15 cm, and nitrogen, phosphorus, and potassium fertilizers. In the winter of the clear garden disinfection method, the pests on the tea are mostly hidden in the tea bushes and overwintering, but in winter, the pesticide should be fully applied in time and be disinfected in the clear garden. The general use of Bomi 0.5-degree lime sulfur in the whole garden spray can kill insects and prevent disease. If pests are still active, 4000 times liquid cypermethrin, 1500 times liquid dichlorvos, and 1,000 times liquid omethoate can be used. When spraying, from the bottom up, spray evenly from inside and outside of the tea bush, leaves, and leaves. The litter in the tea garden is prone to contain pathogens, eggs, etc. It should be burned out to reduce the spread of pests and diseases. Preserve the winter bud method to postpone trimming, keep winter buds to promote early germination next year, and open the garden early. The production shows that it is not pruned in the end of autumn and early spring to ensure the production of the winter tea buds (including latent buds) and can be harvested 710 days earlier. After the spring tea is harvested, it is pruned and the canopy is trimmed. Because the spring buds are of good quality and high price, doing so can obtain higher economic benefits.
