Embodiment 1

[0017] A method for judging the amount of fertilization by using the nutrients of tea leaves, the steps comprising:

[0018] (1) Selection of sample trees: On June 21, set up four sample plots of 20×20m in a certain garden to be tested, follow the "S"-shaped route, and select trees with strong growth, good tree vigor, and Five sample trees with complete crowns and no pests and diseases were used as sampling trees, and a total of 20 sampling trees were selected.

[0019] (2) Field leaf picking method: above the middle part of the canopy periphery, select robust growth branches of the year, collect 20 mature leaves in four directions, east, south, west, and north, and pack them in sealed bags and bring them back to the laboratory for processing.

[0020] (3) Indoor leaf sample treatment: Wipe both sides of the leaf with a clean gauze or towel, remove the petiole, weigh it accurately with an analytical balance, put it in an oven, fix it at 100°C for 25 minutes, and then put it in...

Embodiment 2

[0025] A method for judging the amount of fertilization by using the nutrients of tea leaves, the steps comprising:

[0026] (1) Selection of sample trees: On July 10, set 4 sample plots of 20×20m in a certain garden to be tested. Five sample trees with complete crowns and no pests and diseases were used as sampling trees, and a total of 20 sampling trees were selected.

[0027] (2) Field leaf picking method: above the middle part of the canopy periphery, select robust growth branches of the year, collect 20 mature leaves in four directions, east, south, west, and north, and pack them in sealed bags and bring them back to the laboratory for processing.

[0028] (3) Indoor leaf sample treatment: Wipe both sides of the leaf with a clean gauze or towel, remove the petiole, weigh it accurately with an analytical balance, put it in an oven, fix it at 100°C for 25 minutes, and then put it in a 75°C incubator Dry in the middle for 24 hours, take it out and weigh it again, crush the ...

[0033] A method for judging the amount of fertilization by using the nutrients of tea leaves, the steps comprising:

[0034] (1) Selection of sample trees: On July 25, set 4 sample plots of 20×20m in a certain garden to be tested. Five sample trees with complete crowns and no pests and diseases were used as sampling trees, and a total of 20 sampling trees were selected.

[0035] (2) Field leaf picking method: above the middle part of the canopy periphery, select robust growth branches of the year, collect 20 mature leaves in four directions, east, south, west, and north, and pack them in sealed bags and bring them back to the laboratory for processing.

[0036](3) Indoor leaf sample treatment: Wipe both sides of the leaf with a clean gauze or towel, remove the petiole, weigh it accurately with an analytical balance, put it in an oven, fix it at 100°C for 25 minutes, and then put it in a 75°C incubator Dry in the middle for 24 hours, take it out and weigh it again, crush the s...

Abstract

The invention relates to the technical field of agricultural planting, in particular to a method for judging the fertilizing amount through oil tea leaf nutrients and application thereof. The method comprises the first step of sample selection, the second step of sampling, the third step of treating, the fourth step of element measuring and the fifth step of result judging. The nutrition judging method provides a scientific basis for reasonable fertilizing of oil tea and formulation of cultivation intensive management measures, the loss of nutrient elements can be judged, the balance conditions among nutrients can be judged, the blindness of fertilizer application is reduced, the cost is saved, and the adverse effect on the soil is reduced. Practices prove that by means of the oil tea leaf nutrient judging method, the mu yield of an oil tea garden with balance fertilizer application is increased by 33% or above, and the difference between the yield of a bumper year and the yield of a lean year can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for judging the amount of fertilization by using the nutrients of tea leaves and its application. Background technique [0002] Camellia oleifera (Camellia oleifera Abel.) is an evergreen shrub or small tree of the genus Camellia in the family Theaceae (Theaceae). The plant, whose mature seeds can be used to extract tea oil, is a green, ecological and high-nutrition health-care edible oil, known as "Oriental olive oil", and is an ideal edible oil for the "three high" crowd. (FAO) as a key promotion of healthy high-grade cooking oil. In addition, Camellia oleifera is large and showy, and the flowering period (September-November) coincides with the season of few flowers, which is of great ornamental value. With ecological value. In order to promote the development of camellia oleifera industry, the State Forestry Administration formulated the "National Cam...
