1. Principles of fertilization in tea gardens
The principles of fertilization in tea gardens are as follows: 1. Organic fertilizers, organic fertilizers and inorganic fertilizers; 2. Nitrogen fertilizers, nitrogen, phosphorus and potassium are combined to pay attention to the whole fertilizer; Combination of topdressing and fatning; Fourth, rational fertilization; Fifth, based on rhizosphere fertilization, combined with rhizosphere fertilization and external fertilization.
2. Tea garden fertilization technology
The key point of fertilization technology in tea gardens is to master the fertilization period and fertilization methods.
In terms of base fertilizer, it is appropriate to take the end of autumn and winter. After the stagnation of the tea tree ground or the closure of the garden, the sooner the base fertilizer is applied, the better.
Topdressing is applied in the growing season of tea trees. According to the growth and development needs of tea trees in a year and their regularity, combined with the growth of tea gardens and soil properties, the average young tea tree is applied once a year, and the tea tree of the age is 3 times a year. The period of application of top dressing is generally in the early stage of germination of each season of tea or per round of tea.
Fertilization in tea gardens is carried out by means of acupoint application, ditch application, spreading and root dressing.
Acupoint application is a method of concentrated fertilization and economic use of fertilizer. After the trial of tea planting, the tea tree branches have not been closed before use. Between the two tea plants of the young tea tree, it can be 10 to 30 cm deep from the tea tree; the slope tea garden is applied with topdressing, the spring furrow is open, the summer ditch is opened below, and the rotation is carried out; after applying the top dressing, the soil should be covered in time.
The application is only carried out in a tea garden that has been closed or closed. Because the soil of the tea line is already covered with roots, the amount of application is also large, and it is generally used in the season when the soil is relatively moist.
To avoid causing harm, pay attention to the concentration of fertilization outside the roots. Generally, ammonium sulfate is about 0.5-1%, and superphosphate is 1-2%. The superphosphate used for top dressing needs to be immersed in 1-2 fertilization to have a good effect on the yield increase of tea. However, in order to give full play to its economic effects, it must be combined with agricultural techniques such as rational picking, tea garden irrigation and soil tillage. Regardless of the method used to fertilize, we must combine cultivating and weeding to reduce the loss of fertilizer and weeds.
