Embodiment Construction

[0017] Case 1

[0018]In a tea garden located in a hilly red soil area, a tea garden with an area of ​​2 mu and a planting period of 20 years was selected. The tea tree variety was Fuding Dabai. Add 2g ZnSO per square meter in late winter 4 ·7H 2 O and 20 mg Na 2 SeO 3 And a mixture of nitrogen, phosphorus, calcium and magnesium, and one bud and two leaves of tea are harvested in spring. Results The contents of aluminum, zinc, and selenium in tea were 5 mg / g, 1.2 mg / g, and 0.31 mg / kg, respectively, and organic zinc and organic selenium accounted for 80% and 85% of the total zinc and selenium content in tea, respectively. Other qualities of the tea are up to the standard of high-quality green tea.

[0019] Case 2

[0020] In a tea garden located in a hilly red soil area, a tea garden with an area of ​​2 mu and a planting period of 30 years was selected. The tea tree variety was Fuding Dabai. Add 3g ZnSO per square meter in late winter 4 ·7H 2 O and 30 mg Na 2 SeO ...

Abstract

The invention relates to a planting method of low-aluminum zinc-containing rich-selenium health care tea in a hilly red soil region. The method comprises the following steps that: mixing agents of zinc vitriol, sodium selenite, ammonium nitrate and monosodium phosphate are added into soil external sources according to the major trace element content of red soil and the growth characteristics of tea trees, and then, zinc and selenium annual hyperaccumulators are utilized for relay intercropping after the spring tea picking completion. The planting method has the technical effects that the relay intercropping is carried out, the enriching of the zinc and the selenium in a tea garden is effectively controlled, and the continuous utilization of the soil and the ecological safety of the tea garden are ensured. The zinc content and the selenium content in the tea respectively reach a value higher than 1mg/g and a value higher than 0.3mg/kg, the contents of the organic zinc and the organic selenium are respectively higher than 80 percent, and other qualities of the tea are not obviously changed.

Description

technical field [0001] The invention relates to a tea planting method, in particular to a planting method of a low-aluminum, zinc-containing, selenium-rich health care tea in a hilly red soil area. Background technique [0002] The development of green health food and the demonstration and leading role of green food leading enterprises and brand products are the key to expanding the space for agricultural development, accelerating the strategic adjustment of agricultural industrial structure, and realizing the transformation from traditional agriculture to modern agriculture and from quantitative agriculture to quality-benefit agriculture. An effective way to improve the comprehensive agricultural production capacity. [0003] Tea is one of the characteristic agricultural products with traditional advantages in my country. The output of tea and the planting area of ​​tea trees rank first in the world. In 2010, my country's tea garden area was 1.95 million hectares, an incre...
