Embodiment 1

[0030] In a tea planting base, sort out a piece of nursery field required for one mu of tea garden seedlings, insert the pre-trimmed cutting buds into the nursery field according to the conventional operation steps, cultivate tea saplings, and then transplant them to the tea garden, and finally harvest the tea leaves. After the tea leaves are processed, random samples are taken from the finished tea leaves to detect the total selenium content and the proportion of organic selenium. The result was that the total selenium content in the finished tea was 136.5 μg / kg, and the organic selenium accounted for 78.9%.

Embodiment 2

[0032] In a certain tea planting base, sort out a piece of nursery field required for the seedling quantity of one mu of tea garden, weigh 0.5kg of nano-selenium plant nutrient with an electronic scale, spread it evenly on the seedling-raising sky, and turn it lightly to fully mix the nutrient and seedling-raising soil uniform. Afterwards, the pre-trimmed cutting buds are inserted into the nursery field according to the conventional seedling raising steps to cultivate organic selenium-rich tea seedlings, and then transplanted to the tea garden to finally harvest organic selenium-rich tea leaves. After the tea leaves are processed, random samples are taken from the finished tea leaves to detect the total selenium content and the proportion of organic selenium. The result was that the total selenium content in the finished tea was 263.7 μg / kg, and the organic selenium accounted for 86.4%.

Embodiment 3

[0034]In a tea planting base, sort out a piece of nursery field required for the seedling quantity of one mu of tea garden, weigh 1.0kg of nano-selenium plant nutrient with an electronic scale, spread it evenly on the seedling-raising sky, and turn it lightly to fully mix the nutrient and seedling-raising soil uniform. Afterwards, the pre-trimmed cutting buds are inserted into the nursery field according to the conventional seedling raising steps to cultivate organic selenium-rich tea seedlings, and then transplanted to the tea garden to finally harvest organic selenium-rich tea leaves. After the tea leaves are processed, random samples are taken from the finished tea leaves to detect the total selenium content and the proportion of organic selenium. The result was that the total selenium content in the finished tea was 583.4 μg / kg, and the organic selenium accounted for 84.7%.

Abstract

The invention discloses a Se-enriched tea seedling, a culturing method thereof and an organic Se-enriched tea product. Each Se-enriched tea seedling has the total Se content of 0.26-6.4mg in the transplanting process. The method comprises the step of adding a nano Se plant nutrient into seedling culturing soil in the tea seedling culturing stage to culture the Se-enriched tea seedling according to a tea seedling culturing method. The Se content of the organic Se-enriched tea is 250-5000mug / kg, wherein the content of organic Se is larger than or equal to 80%. The tea is rich in the Se element of which the content is unified; and by using the method, the proportion of the organic Se is increased, the problem on the stability of Se contents of teas in different growth batches in the prior art is solved, the Se contents of the teas are kept unified, and standard and mass production can be realized.

Description

technical field [0001] The invention relates to tea seedlings for producing tea leaves rich in organic selenium and a cultivation method for the tea seedlings. The utility model belongs to the field of agricultural fertilization and agronomic technology. Background technique [0002] China is the hometown of tea and the ancient country of tea. The discovery and utilization of tea trees has a history of more than 10,000 years. It is the birthplace of human beings drinking tea, growing tea and making tea. Tea has become the most vital and popular civilized and healthy beverage among the three major beverages in the world. With the improvement of people's living standards, the enhancement of health awareness and the rise of tea culture, people's demand for tea quantity and quality is gradually increasing and improve. [0003] Selenium, element symbol Se, is an essential trace element for the human body and is the active center of glutathione peroxidase (GSH-Px). It has biolo...
