Description

Technical Field

[0001] The invention relates to the technical field of cultivating old white tea trees under forests, and in particular to a process for cultivating old white tea trees under forests. Background Art

[0002] "Adhere to the development concept that green waters and green mountains are gold and silver mountains, manage and protect the ecological environment for the growth of tea trees, implement the "tea forest symbiosis" management model, scientifically manage, and greenly prevent and control, so as to purify and rejuvenate the germplasm of Fuding tea trees, promote the sustainable, green and high-quality development of Fuding's tea industry, and provide high-quality tea germplasm resources..."

[0003] The core protection area of ​​the old tea tree community is located in the southwest foot of the Taimu Mountain Range, a national 5A-level scenic spot. The forest coverage rate of the protection area is over 99%. It is rich in ecological resources, with a large temperature difference between day and night, clouds and mist all year round, and fresh air. It is a paradise for the growth of tea trees. The construction of the protection area began in December 2017 and was completed in October 2021.

[0004] The reserve is based on the concept of "tea forest symbiosis" to restore the original growth environment of tea trees. It is based on some scattered old tea trees in the wilderness in the Taimu Mountain Forest Farm area, and is collected and planted from old tea trees in the wilderness found in the deep mountains and old forests of Fuding. The tea tree varieties of the old tea tree community in the reserve are mainly Fuding Caicha (Tuchazai), Fuding Dabaicha (Huacha No. 1), Fuding Dahaocha (Huacha No. 2), Gelecha, Zaofengchun, etc., with a tree age of more than 30 years. Among them, there are 5,000 Fuding Caicha, 30,000 Fuding Dabaicha old tea trees, 150,000 Fuding Dahaocha old tea trees, 2,500 Gelecha, 2,500 Zaofengchun and 10,000 other varieties. Protecting these non-renewable and irreplaceable old tea trees is a living witness to the origin of Fuding tea trees and the long history of tea planting and tea use.

[0005] It is understood that as the only "Core Protection Area of ​​Fuding Old Tea Tree Community" in the country, it is of great significance to build and maintain the "Core Protection Area of ​​Old Tea Tree Community" well. Protecting old tea trees and enriching the tea tree germplasm gene pool is the foundation and germplasm support for promoting the sustainable development of the tea industry. It is also a public welfare cause that will benefit future generations. It will provide a steady stream of high-quality tea varieties for the sustainable, green and high-quality development of the Fuding white tea industry, and make new and greater contributions.

[0006] Based on the development of tea forest symbiotic tea planting technology, this case aims to propose a technology for the protection and development and utilization of old white tea trees and its process flow, and proposes a method in the process of old tea cultivation that can assist planters in solving the difficulty of frequent watering and fertilizing in the process of tea tree cultivation under the premise that large-scale transportation equipment cannot be used under the forest.

[0007] In order to solve the above problems, this example designed a process for cultivating old white tea trees under the forest, and the process steps include:

[0008] Step 1. Forest land clearing: Forest land clearing is the preparatory work before land preparation and seedling planting. The method is to completely cut the weeds and bamboos under the canopy, remove the Masson pine in combination with pine wood nematode control, and retain all the original trees. The grass stumps are required to be close to the ground, the bamboo stumps are less than 5cm high, and the cut ground cover is crushed;

[0009] Step 2. Strip the humus soil: Strip the surface humus soil and topsoil at the location where the hole is to be dug and place them aside;

[0076] When cultivating and maintaining tea trees by using the white tea old tree cultivation component:

[0077] When transplanting and planting old tea trees, the main stems of tea leaves are placed in the main stem slots 103 and the main stem slots A109, and the lower end surface of the sleeve block 108 is in contact with the root of the tea tree. The tea trees are planted at this time. When planting, the soil is buried to a height above the connection between the connecting column 117 and the water tank 101 and below the height of the turning circle 131.

[0078] After the planting is completed, the user fills the water tank 102 with water, and fills the fertilizer storage tank 105 with powdered or granular fertilizer, and rotates the rotating ring 131 to drive the transmission gear 123 to rotate, and then drives the transmission shaft 128 and the threaded rod 133 to rotate, and then adjusts the height of the adjusting slider 137, and then adjusts the space between the wedge-shaped fixed block 136 and the wedge-shaped water-permeable groove 135 to adjust the amount of water seepage;

[0079] When the amount of water in the water tank 118 reaches the preset value of the valve 114, the valve 114 opens and discharges the water in the water tank 118 into the annular groove 111 through the seepage hole valve 114 to infiltrate the permeable cotton body 112, and then infiltrates the roots of the tea tree through the permeable cotton body 112, and diffuses from the main root of the tea tree to the sub-roots, and when the water level in the water tank 118 drops, the buoyancy traction block 115 falls and drags the slider 146 to move to the left, and brings the fertilizer that falls into the through hole 147 into the water tank 118. When the water enters next time, the slide 145 gradually resets and dissolves the fertilizer. Similarly, the fertilizer diffuses from the main root of the tea tree to the sub-roots, thereby increasing the absorption rate of the fertilizer.

[0080] During use, by opening the flap 152, rainwater can be collected and utilized on rainy days.

[0081] The beneficial effects of the present invention are as follows: when in use, the user only needs to bury the cultivation device together with the planted old white tea trees. During the growth of the white tea, the roots of the white tea can be moistened and watered at a preset speed through the device, and fertilizer can be applied to the roots of the white tea. Compared with the previous large-scale watering method, the previous large-scale watering is bound to cause a large amount of water loss, and the tea trees actually use only a small amount of water. Therefore, it brings more labor to farmers when it is inconvenient to carry water under the forest. Similarly, the present device adopts a method of multiple small-scale fertilization to add fertilizer. Compared with the previous large-scale fertilization method, the utilization rate of the fertilizer is increased, and the absorption of fertilizer by surrounding weeds is reduced, the growth of weeds is inhibited, and the difficulty of subsequent weeding is reduced.

[0082] Through the above methods, those skilled in the art can make various changes according to the working mode within the scope of the present invention.
