How to operate early spring tea? 1. Weeding and loosening the soil: After 4-5 months of rain and snow in the tea garden, the soil has become compacted and some grass has grown. At this time, the soil temperature is lower. Therefore, weeding and loosening the soil in the tea garden before spring tea mining is beneficial to loosening the soil, increasing soil temperature, cutting weeds, reducing water and nutrient consumption, and promoting early germination of spring tea. Weeding is usually carried out at the end of February or early March at a depth of 10-15cm.

2. Apply germination fertilizer: Germination fertilizer should be applied sooner rather than later. Dig a ditch 15-20 cm away from the roots of the tea tree and apply 30-35 kg of urea or 30 kg of compound fertilizer or 2000-2500 kg of decomposed manure per mu. After application, cover the soil. For tea gardens where it is impossible to dig ditches for fertilization, you can sprinkle urea on rainy days and shake the tea shed with bamboo poles to let the fertilizer fall into the soil. three. Pruning: It is best to prune at the end of February before stinging, and no later than March 10. Therefore, after a winter of dormancy, the stems and roots of the tea tree store more nutrients and can be easily restored after pruning. In addition, as the temperature rises in early spring, the pruned branches are not easily damaged by freezing, and the labor force is not tight, so it is easy to master. Tea gardens generally advocate light pruning, that is, cut off last year's autumn shoots (green stems) and retain spring and summer shoots (red stems), and cut off about 2-3cm. If the crown of the tree is frozen, prune it according to the degree of frost. Pruning should be shallow rather than deep to avoid cutting off some branches that can still sprout. For tea gardens where famous tea is not frozen, spring pruning can be changed to pruning after the spring tea is over to facilitate picking of early spring tea leaves.

Four. Anti-freeze: The climate in early spring is abnormal, and the temperature fluctuates between warm and cold. This kind of climate condition is extremely unfavorable for the production of high-end famous tea in tea gardens. In early spring, you should always pay attention to the local weather forecast and take measures to prevent colds in late spring. After the cold wave forecast is released, for tea gardens with early budding leaves, manpower must be concentrated to harvest young leaves to reduce frost damage losses.

In tea gardens on windward slopes that are prone to freezing, cover tea sheds with straw, weeds or sunshade nets, and remove the covering promptly after the cold wave passes. After the tea tree suffers frost damage, corresponding care and rejuvenation measures must be taken according to the freezing situation to restore the tea tree's vigor as soon as possible.

Verb (abbreviation of verb) to clear ditches and drain water: There is a lot of rain in spring. If the tea garden has poor drainage, the tea trees will be susceptible to waterlogging and root rot, resulting in delayed tea buds and reduced yields. Therefore, it is necessary to dig ditches for drainage in a timely manner and clear the drainage ditches to ensure that the groundwater level is below 1m. This way, when the rain stops, the tea gardens will dry up and there will be no water.

Intransitive verb to supplement foliar fertilizer: In early March, when the temperature exceeds 12°C, the absorption function of tea leaves can be used to supplement fertilizer outside the roots to promote early germination of tea trees, increase yield, and improve quality. 0.5% urea, 0.3% potassium dihydrogen phosphate, multi-functional nutrient solution "Zhongchazao", and hormone "920" can be used for in vitro fertilization.
