The one-year plan is spring, and the production of spring tea is the highlight of tea production. In order to give full play to the economic benefits of spring tea and realize the goal of increasing the income of tea farmers, it is very important to strengthen the spring management of the production of tea gardens and young tea gardens. The relevant technical measures are as follows: 1. Early application of germination fertilizer. After the beginning of spring, the tea tree was first released from the roots, and gradually entered a growth peak. This is the active period of root growth and the peak of suction fertility. Therefore, applying the available nitrogen fertilizer in time before the root system becomes active can play a role in germination and sprouting. Generally held in late February to early March. It depends on the early spring climate and tea varieties. Early bud varieties should be applied about 7 days earlier. Each mus of urea can be applied to 20-30 kg of urea. Attention should be paid to the method of fertilization. A fertilization ditch with a depth of about 15 cm should be dug below the outside of the crown of the row and be applied evenly. If the soil surface is spread, care should be taken not to spread it from the canopy surface so as to avoid causing fertilizer damage. 2, timely spraying foliar fertilizer. Tea leaves can directly absorb and use low-level liquid fertilizers, which can partially make up for the lack of nutrients in the roots, promote buds and leaves, and have a quick effect. Generally master 0.5 ~ 1% of urea plus 0.5% potassium dihydrogen phosphate mixed application, can also use special tea leaf nutrition fertilizer. After the shoots started sprouting, they were sprayed with a sprayer after 3:00 pm on sunny days (all days of cloudy days). Before the spraying, add a small amount of water to dissolve the fertilizer and dilute with water. Spray it once every 7 days or so and spray it continuously 2 or 3 times. The effect is better. The spray should be uniform and the front and back of the blade should be wetted. 3, shallow tillage weeding. Shallow ploughing before spring tea is an important measure to increase production of spring tea. After several months of rain and snow in the tea plantations, the soil has been compacted and the soil temperature is low. The cultivation can both loosen the soil and remove the weeds in early spring. After the cultivation, the soil is loose and the topsoil is easy to dry to increase the soil temperature. It helps to promote early spring tea germination. The early buds were planted in early March. The others were held in the middle and early March. The fields were cultivated on sunny slopes and the slopes could be tilled. The depth of cultivation is controlled at 10-15 cm. It can be used in conjunction with the application of budding fertilizer.
