Embodiment 1

[0015] A high-efficiency drip irrigation and fertilization method for famous green tea picking tea gardens. During the implementation process, the drip irrigation belt is laid with double pipes, placed on both sides of the tea row, and 15cm away from the roots of the tea trees. Dissolve water-soluble organic and inorganic fertilizers in water for drip irrigation, specifically 3 times in the spring tea season, 1 time in the summer tea season, 1 time in the autumn tea season, and 1 time during the base fertilizer application at the end of the tea season.

[0016] The applied fertilizers are water-soluble organic and inorganic fertilizers, and the water-soluble organic fertilizers are: fulvic acid; the water-soluble inorganic fertilizers are: urea, dipotassium hydrogen phosphate, potassium sulfate, magnesium sulfate, and the consumption of organic fertilizers accounts for 25%. P 2 o 5 、K 2 The annual consumption of O and MgO is respectively 300kg / ha, P 2 o 5 60 kg / ha, K 2 O...

Embodiment 2

[0018] A high-efficiency drip irrigation and fertilization method for famous green tea picking tea gardens. During the implementation process, the drip irrigation belt is laid with double pipes, placed on both sides of the tea row, 20 cm away from the roots of the tea trees. Dissolve water-soluble organic and inorganic fertilizers in water for drip irrigation, specifically 3 times in the spring tea season, 1 time in the summer tea season, 1 time in the autumn tea season, and 2 times during the end of the tea season.

[0019] The fertilizer used is water-soluble organic and inorganic fertilizer, water-soluble organic fertilizer is: fulvic acid; water-soluble inorganic fertilizer is: urea, dipotassium hydrogen phosphate, potassium sulfate, magnesium sulfate, the consumption of organic fertilizer accounts for 30%, N, P 2 o 5 、K 2 The annual consumption of O and MgO is 225 kg / ha respectively, P 2 o 5 67.5 kg / ha, K 2 O 67.5kg / ha, MgO 20kg / ha. The ratio of water to fertilizer...

example

[0021] From 2016 to 2018, the methods of Examples 1 and 2 were used to carry out field experiments in famous and high-quality green tea picking tea gardens.

[0022] As shown in Table 1, compared with the customary practice, the method of the present invention can save fertilizers by more than 30% on average (wherein the fertilizer weight loss is more than 35%), increase production by 35.8-118.7% (77.3% on average), and increase the income of tea farmers (an average increase of 2090 yuan / mu).

[0023] The quality characteristics of green tea are fresh taste and low bitterness, so high free amino acid content, appropriate tea polyphenol content, and low phenol-to-ammonia ratio are required. Therefore, from the results in Table 2, the changes of drip irrigation and fertilization on the quality components of green tea The effects are limited and do not significantly alter the quality components of green tea.

[0024] Therefore, drip irrigation and fertilization have a positive e...

Abstract

The invention discloses a high-efficiency drip irrigation and fertilization method for a famous green tea picking garden, and belongs to the technical field of irrigation and fertilization of tea gardens. The high-efficiency drip irrigation and fertilization method comprises the following steps: dissolving water-soluble organic and inorganic fertilizers into water through a fertilizer drip irrigation pipeline to perform accurate drip irrigation fertilization on tea trees; regulating and controlling the annual drip irrigation and fertilization as follows: 6-7 times of drip irrigation and fertilization in drip irrigation fertilization, 3 times of drip irrigation and fertilization in the spring tea season, 1 time of drip irrigation and fertilization in the summer tea season, 1 time of drip irrigation and fertilization in the autumn tea season and 1-2 times of drip irrigation and fertilization in the base fertilizer application period at the end of the tea season; and controlling the annual drip irrigation fertilizer application amount, wherein on the basis of pure N, the annual nitrogen use amount is 220-300 kg / ha, P2O5 is 60-70 kg / ha, K2O is 65-90 kg / ha, MgO is 18-22 kg / ha, and the use amount of an organic fertilizer accounts for 20-30%. According to the method, nutrients are directly delivered to the positions close to the root systems of the tea trees through the pipelines, thetea trees are subjected to precise drip irrigation and fertilization, the utilization efficiency of the fertilizer is obviously improved, the weight loss and yield increase effects are obvious, and meanwhile, the environmental pollution is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of irrigation and fertilization of tea gardens, and in particular relates to a method for efficient drip irrigation and fertilization of famous and high-quality green tea picking tea gardens. Background technique [0002] As an advanced drip irrigation method, drip irrigation is integrated with fertilization, which can accurately control water and fertilizer, reduce nutrient loss caused by vertical infiltration and surface runoff, and thus improve the efficiency of nutrient utilization by plants. [0003] Drip irrigation and fertilization have been applied to fruits and vegetables, food crops, etc., and the effect is obvious. However, the application on tea trees is still in the initial stage so far, and the relevant technical parameters are not yet clear, let alone drip irrigation and fertilization technology. [0004] Although the drip irrigation and fertilization technology on fruits, vegetables and food...
