Method for quickly forming gardens by young tea trees

Abstract

The invention provides a method for quickly forming gardens by young tea trees. The method comprises the following steps that the young tea trees are transplanted in December of the last year to February of the next year, the tea trees are shaped and trimmed for the first time after being transplanted, and the distance between cut openings and the ground is 15-20 cm; foliar fertilizer is sprayed when buds of the tea trees germinate to 1-20 mm, and topping is carried out on new shoots of the tea trees after the new shoots of the tea trees grow to 15-30 cm; the roots of the tea trees are fertilized at the end of October to the beginning of December, and urea topdressing is performed on the roots of the tea trees 5-20 days before spraying of the foliar fertilizer; shaping and pruning are carried out on the tea trees for the second time in spring of the next year, wherein the pruning height is increased by 18-20 cm from the cut openings of the last time to remove main branches; in the third year, when young shoots of the tea trees grow to 15-25 cm each time, light pruning is conducted; and the tree width of the tea trees reaches 1.2 m or above after three years. According to the method provided by the invention, a specific culture medium is not needed, the fluffy surface amplitude of the tea trees cultured for three years can reach 1.2 m or above, and the yield and quality of tea leaves are higher.

Description

technical field [0001] The invention belongs to the related technical field of tea tree planting, and in particular relates to a method for quickly growing a garden of young tea trees. Background technique [0002] It takes 3-5 years for tea trees to become regular production tea gardens after planting tea seedlings for nutrient management, tree pruning, field impurity removal and pest control. Due to the unreasonable cultivation and management methods in traditional young tea gardens, the loss of soil nutrients is serious. In addition, young tea trees are in the root development stage after planting, resulting in a low rate of nutrient absorption and utilization of tea trees, resulting in slow growth of tea trees, and field weeds During this period, it competes with tea trees for nutrients, and weeds often grow wildly while tea seedlings stagnate or even die, which greatly increases the burden on tea farmers and tea enterprises. [0003] At present, some predecessors have ...

Due to the unreasonable cultivation and management methods in traditional young tea gardens, the loss of soil nutrients is serious. In addition, young tea trees are in the root development stage after planting, resulting in a low rate of nutrient absorption and utilization of tea trees, resulting in slow growth of tea trees, and field weeds During this period, it competes with tea trees for nutrients, and weeds often grow wildly while tea seedlings stagnate or even die, which greatly increases the burden on tea farmers and tea enterprises

[0003] At present, some predecessors have studied the rapid gardening method of tea trees. For example, the Chinese patent publication CN201811528141.5 discloses a method for rapid gardening of tea trees. This method adopts the mode of water and fertilizer integration + drip irrigation. At present, there are many In regional application, the method of dripping fertilizers to the roots is used to accelerate the growth of tea trees. Although it has a certain effect, the nutrient utilization rate of young tea trees is still low before the tea tree canopy is unfolded (that is, before the tea tree body is fully stretched). , most of the water-soluble fertilizers will be absorbed and utilized by weeds, causing weeds to grow wildly and the cost of weeding is high; Chinese patent publication CN201310286001.2 discloses a method for quickly growing golden bud tea leaves, which uses tea tree grafting method, but tea tree grafting has higher requirements on the operation of workers and stricter requirements on the climate and environment during the grafting period. Not all tea areas can use it, and the survival rate of grafting is not as high as that of conventional planting management. The quality of tea produced There are also differences in quality from the ear

In addition, tea tree grafting must first require that there is an old tea garden in the area and meet the grafting conditions. In the newly opened tea garden, there is no tea tree mother tree, which is not suitable for the application of this method; Chinese patent publication CN201910688666.3 discloses a fast-growing tea seedling The method and its application in the rapid growth of garden species, the method of matrix layering is used to promote the growth rate of tea seedlings, during which the tea seedlings are sprayed with foliar fertilizer containing gibberellin to accelerate their growth and promote the rapid growth of tea trees. Garden, but this method uses gibberellin extensively, only stipulates its concentration, improper operation will lead to inhibition of tea tree growth, and this method needs to be used in combination with a specific substrate
