Water and fertilizer integration technology mode suitable for north tea gardens

Abstract

The invention discloses a water and fertilizer integration technology mode suitable for north tea gardens, and belongs to the technical field of tea tree cultivation. The mode includes construction of a fertilizer formulation pool, an installation method of a venturi and a water meter, main water pipe laying, branch pipe micro-spraying tape placement, high-pressure water spraying and low-pressure fertilization technical measures and the like. The mode is characterized by comprising the steps: dissolving a water soluble fertilizer in the fertilizer formulation pool, and placing a micro-spraying tape between two rows of tea trees; through controlling a switch of the venturi, carrying out spray irrigation water application in the high water pressure and the high flow quantity, and carrying out drip irrigation fertilization in the low water pressure and the low flow quantity; after fertilization is completed, carrying out spray irrigation again; and changing a fertilization mode of 'one-time base fertilizer application and three-time top application' into a mode of 'one-time base fertilizer application and six-time top application'. Compared with the prior art, spray irrigation is carried out in the high water pressure and the high flow quantity, so that requirements of tea garden irrigation are met, and a tea garden 'microclimate' is regulated and controlled; drip irrigation of the water soluble fertilizer is carried out in the low water pressure and the low flow quantity, so that the fertilizer is allowed to be farthest distributed around tea tree rhizospheres, and fertilizer absorption of the tea trees is facilitated; and at the same time, a past tea garden three-time top application is changed into multi-time top application, continuous fertilizer requirements of the tea trees are met, and the purpose of saving water and the fertilizer is achieved.

Problems solved by technology

[0002] Moisture is related to the intensity and direction of tea tree metabolism, and also affects the formation and accumulation of various organic substances in tea, which also has a great impact on yield and quality. However, the air in northern tea gardens is dry, and rainfall and general irrigation cannot meet the water demand of tea trees.

There are mainly five problems with the various spray and drip irrigation equipment used in some tea gardens: 1. The cost of the spray and drip irrigation equipment used is often too high, which is not suitable for large-scale promotion in tea gardens; 2. Some sprinkler irrigation equipment is placed in large tea houses. In the middle, it affects other agricultural activities in the tea garden; 3. The sprinkler head used is easily blocked and damaged; 4. It is not easy to combine with fertilization, and the fertilization effect is not good; 5. The uniformity of water spray is poor, and the water cannot be irrigated to the tea tree rhizosphere to the maximum extent. around

This mode mainly has the following disadvantages: 1. It is easy to cause damage to the root system of the tea tree; 2. Concentrated fertilization causes a waste of fertilizer; 3. The fertilizer effect is short and cannot continuously provide nutrients for the tea tree; 4. It requires a large amount of labor to fertilize.
