Embodiment 1

[0036]Fixed-value irrigation: When the average relative soil moisture content of the soil layer within 40cm depth drops to 65%, the surface drip irrigation method is used to irrigate until the average relative soil moisture content of the soil layer within 40cm depth is 87%. The data obtained from the calculation of the wet depth is used for constant value irrigation, and the drip irrigation speed is controlled so that no obvious runoff is formed on the surface.

[0037] Optimal fertilization: organic fertilizer is combined with chemical fertilizer. The organic fertilizer is cassava stalks mixed and crushed after the cassava residue is decomposed. The application rate is 320kg / hm 2 , the traditional chemical fertilizer is a mixture of nitrogen, phosphorus and potassium fertilizers, and the application rate is: urea 250kg / hm 2 , P 2 o 5 60kg / hm 2 , K 2 O 150kg / hm 2 .

[0038] Fertilization method: dig a fertilization pit 25cm away from each tea tree, with a depth of 18cm...

Embodiment 2

[0042] Fixed-value irrigation: When the average relative soil moisture content of the soil layer within 40cm depth drops to 70%, the surface drip irrigation method is used to irrigate until the average relative soil moisture content of the soil layer within 40cm depth is 90%. The data obtained from the calculation of the wet depth is used for constant value irrigation, and the drip irrigation speed is controlled so that no obvious runoff is formed on the surface.

[0043] Optimal fertilization: organic fertilizer is combined with chemical fertilizer. The organic fertilizer is cassava stalks mixed and crushed after the cassava residue is decomposed, and the application rate is 400kg / hm 2 , the traditional chemical fertilizer is a mixture of nitrogen, phosphorus and potassium fertilizers, and the application rate is: urea 300kg / hm 2 , P 2 o 5 70kg / hm 2 , K 2 O 200kg / hm 2 .

Embodiment 3

[0048] Fixed-value irrigation: When the average relative soil moisture content of the soil layer within 40cm depth drops to 75%, the surface drip irrigation method is used to irrigate until the average relative soil moisture content of the soil layer within 40cm depth is 92%. The data obtained from the calculation of the wet depth is used for constant value irrigation, and the drip irrigation speed is controlled so that no obvious runoff is formed on the surface.

[0049] Optimal fertilization: organic fertilizer is combined with chemical fertilizer. The organic fertilizer is cassava stalks mixed and crushed as organic fertilizer after the cassava residue is decomposed. The application rate is 450kg / hm 2 , the traditional chemical fertilizer is a mixture of nitrogen, phosphorus and potassium fertilizers, and the application rate is: urea 350kg / hm 2 , P 2 o 5 80kg / hm 2 , K 2 O 250kg / hm 2 .

Abstract

The invention discloses a fertilizer for tea trees and a water and fertilizer application method for the tee trees. The water and fertilizer application method combines constant-value irrigation with optimized fertilization and provides a scientific technology for tea growers on an aspect of water and fertilizer management. Compared with the conventional water and fertilizer management, after being used, the water and fertilizer management technology has the advantages that more water, time and labor are saved, and the yield and quality of fresh tea leaves are greatly increased.

Description

technical field [0001] The invention relates to the field of tea tree planting, in particular to a tea tree fertilizer and a tea tree water and fertilizer application method. Background technique [0002] At present, tea products are increasingly diversified, and market competition is becoming more and more fierce. The focus of competition is quality and output. Soil water and fertilizer conditions can be said to be the basic factors affecting the yield and quality of tea. Appropriate water supply is the condition to promote the full function of tea tree nutrients. Nutrients can also ensure the full function of water in tea trees from many aspects. Fertilization can promote tea tree root development and Expanding the water-seeking space will increase the tea yield with the increase of the root system of the tea tree, and can also increase the water use efficiency. Therefore, improving the water and fertilizer conditions is the basis for improving the quality of tea. However...
