Water balance tea tree watering method based on weather forecast information

Abstract

The invention provides a water balance tea tree watering method based on weather forecast information. The method comprises the steps of according to the weather forecast data of a tea garden region in the future one week or one month in the state meteorological administration, updating a weather prediction result of the target tea garden area every day, then calculating a current soil water content change curve of the target tea garden area, predicting the soil water content of the target tea garden area in the latest rainfall in the future, finally converting the rainfall in the weather prediction result of the target tea garden area into the soil water content, and generating an automatic watering strategy in combination with prediction of the soil water content of the target tea gardenarea in the latest rainfall in the future. According to the method, automatic and reasonable watering and irrigation are effectively achieved according to weather conditions and weather prediction information, and the situation that the soil moisture content is too high or too low after watering is avoided.

Description

technical field [0001] The invention relates to the technical field of tea tree planting, in particular to a water balance tea tree watering method based on weather forecast information. Background technique [0002] Tea tree, formerly known as: tea, Latin name: Camellia sinensis (L.) O.Ktze., Camellia, Camellia shrub or small tree, twigs glabrous. Leaves leathery, oblong or elliptic. The leaves of the tea tree can be used to make tea (different from the tea tree), the seeds can be used to extract oil, the material of the tea tree is fine and dense, and its wood can be used for carving. The distribution is mainly concentrated between 16 degrees south latitude and 30 degrees north latitude. Tea trees like warm and humid climates. The buds start to germinate when the average temperature is above 10°C, and the optimum temperature for growth is 20-25°C; the annual precipitation should be above 1000 mm; Sun-loving and shade-tolerant, it is suitable for growing under diffuse lig...

Problems solved by technology

For example, tea trees require sufficient soil moisture (that is, the soil has good air permeability, water permeability, and water storage performance), but if too much water is deposited in the soil, the root system of the tea tree will be drought-flooded, causing the roots of the tea tree to drown due to lack of oxygen. and so on; the current tea tree planting process is automatically watered and irrigated by setting the time, but the water in the tea tree soil is not only related to manual watering, but also related to factors such as the water storage capacity of the soil and weather changes, so , in the daily planting process of tea trees, there are strict requirements on the timing of watering and irrigating tea trees. If there is rainfall before or after the timing of watering and irrigating, it will cause excessive water accumulation in the roots of tea trees, and the roots will be flooded and the tea trees will wither. If there is no rainfall for a long time before or after watering, and the amount of watering and irrigation at the same time is not enough to ensure the long-term growth of the tea tree, the water absorption of the tea root cannot meet its requirements, and the tea tree will also wither and die.
