Going to winter and spring, due to the continuous low temperature and drought, the tea trees in our county are affected to varying degrees. The management of spring tea garden directly affects the output and benefits of spring tea. At present, it is the key time for the management of spring tea gardens. We will do a good job in the management of tea gardens and lay a good foundation for increasing production and income of spring tea.
1. Reasonably trim and cultivate the canopy
For the severely frozen tea garden, cut off the frozen dry branches, and trim the degree to cut the green stems. The frozen tea garden can be lightly trimmed or deeply trimmed after spring tea to smooth the crown surface, laying a good foundation for summer and autumn tea production. The young tea garden is shaped and pruned according to the age of the tree. The height of the seedlings is 15 to 18?M in 1 year, and the seedlings in 2 to 3 years are improved by 15?M in the previous year. When you put it into the garden, you should master the tingling and not deep, and only cut off the "chicken claw branch", "dead branch", "sick branch", "bumping branch", usually cut 5-7 cm, so as not to cut it. Splendid branches can cause unnecessary losses.
2. Temporarily loosen the soil and remove the weeds
According to the climate characteristics of our county and the requirements of famous tea production, it is necessary to timely grasp the favorable conditions of low rain and clear weather, and carry out shallow tillage to facilitate loosening the soil, increase the ground temperature, remove weeds, and reduce the consumption of water and nutrients. The shallow tillage time should be completed in early March, and the depth should be about 10 cm.
3, scientific fertilization, germination and strong trees
The key measure for high-yield and high-quality spring tea is to re-apply organic fertilizer and apply top dressing early. Production should be based on tea varieties to apply "germination fertilizer", generally 15 days before the germination of tea buds, that is: acre of organic compound fertilizer 50? K or decomposed soil fertilizer 2000 ~ 2500? K, along the edge of the canopy ditch 10 ～15?M applied, while applying the cover soil, pay attention to the deep application. Young tea gardens should increase the amount of phosphorus and potassium fertilizers appropriately. In the freezing of tea gardens, it is necessary to increase the input of fertilizer and water in the spring, mainly based on organic fertilizer, rationally mix with NPK fertilizer and micro-fertilizer, and pay close attention to the application of germination fertilizer to ensure the growth of the tree.
4, timely watering, drought protection
Spring is the peak period of tea tree water demand. In the middle of March, according to soil moisture and tea tree germination, combined with fertilization, germination water is promoted to promote germination and growth. After watering, it is necessary to timely cultivate, prompting the ground temperature to rise as soon as possible, and has achieved the purpose of nourishing the trees and promoting germination.
5, seedlings to replenish seedlings, cultivate strong seedlings
For the newly established clonal tea plantation in autumn and winter last year, it is the key to ensure that Miao Qi is the key. If there is no survival, it is necessary to replenish the seedlings in time, and fill the roots with water after replenishing the seedlings. For tea gardens that pass through Taichung, it is necessary to cut off the excess growing branches, and keep 4-5 strong growing branches in each nest.
6. Prepare early to prevent "cold spring"
The spring climate is prone to cold springs. It can be covered by tea gardens. It should be covered with straw, film, shading net and other coverings on the surface of the tea tree before the cold and cold wave, to protect the tea trees against the cold and cold, and improve the antifreeze ability.
