Rice leaf temperature difference control irrigation system

Abstract

The invention discloses a rice leaf temperature difference control irrigation system, relating to the technical field of farm irrigation. The rice leaf temperature difference control irrigation system comprises an irrigation control system, a wireless humiture measurement transmission system and an upper computer, wherein the wireless humiture measurement transmission system is arranged in a rice field, and is used for collecting the temperature and humidity of atmospheric environment and the temperature of leaves and transmitting the collected data to the upper computer by virtue of a wireless network; and the upper computer is used for processing data collected by the wireless humiture measurement transmission system and controlling the irrigation control system to irrigate the rice field according to the leaf temperature average value and air temperature average value. According to the leaf temperature difference irrigation, irrigation water amount can be reduced, the amount of water evaporated among plants and water consumed for field leakage ecology and plant transpiration can be reduced, and the purpose of automatically accurate irrigation with reduction of labor and good water-saving effect is realized.

Description

technical field [0001] The invention relates to the technical field of farmland irrigation, in particular to an irrigation system for rice leaf temperature difference control. Background technique [0002] The traditional rice in our country is irrigated according to whether the soil is short of water or not, and the paddy field is irrigated when there is no water; the irrigation method is mainly flood irrigation, and the water layer is used for irrigation during the various stages of rice transplanting to maturity; the depth of the water layer is based on Different regions, rice types and growth periods vary, generally 3-5cm. This irrigation method has poor root development, easy lodging, premature aging, low seed setting rate, many diseases and insect pests, low and unstable yield, and low water use efficiency. In the past 30 years, with the development of industrial production and the increase of domestic water consumption, the situation of water resource stress has beco...

Problems solved by technology

[0004] In the routine water management of farmers, it is common to release water directly through ditches for irrigation, but it is often overflowing. The rice fields are in a state of long-term flooding, and excessive irrigation water is invested, resulting in a great waste of water resources.

Among water-saving irrigation technologies for rice, the application of water-saving irrigation technologies such as wet irrigation, intermittent irrigation, alternating wet and dry irrigation, and film-covered dry farming have significantly promoted the reduction of irrigation water in rice fields and the improvement of water use efficiency. Alternate wet irrigation (also known as intermittent irrigation) is a common measure for water-saving irrigation of rice, which can reduce the amount of irrigation water and improve water use efficiency, but it does not take into account the physiological water demand of rice. It will reduce the effective panicle and 1000-grain weight, and the rice yield will not be high; and the probability of these water management is very high, if there is no good environmental weather and matching ditches, and a lot of manpower to carry out careful management, saving water is hard to reach

The existing water-saving irrigation mode of farmland has remarkable water-saving effects of sprinkler irrigation and drip irrigation, but due to the high cost of irrigation equipment, sprinkler irrigation and drip irrigation are not suitable for large-scale promotion in rice production

[0005] The current flood irrigation in rice production in our country has caused great waste of water resources

Among water-saving irrigation technologies for rice, the application of water-saving irrigation technologies such as wet irrigation, intermittent irrigation, alternating wet and dry irrigation, and film mulching has played a significant role in reducing the amount of irrigation water in rice fields and improving water use efficiency, but they have not been fully considered. Due to the physiological water demand of rice, water saving has led to low rice yield; and these water management technologies do not have a good environmental weather and ditch engineering support, and a lot of manpower for careful management, water saving is almost difficult to achieve

The existing sprinkler irrigation and drip irrigation in farmland have remarkable water-saving effects, but due to the high cost of irrigation equipment, sprinkler irrigation and drip irrigation are not suitable for large-scale promotion in rice production

Therefore, a direct and practical irrigation method is needed to solve the labor-intensive, time-consuming and water-wasting problems of irrigation.
