Description

Rice leaf temperature difference control irrigation system
Technical field
The utility model relates to field irrigation technical field, particularly relates to a kind of rice leaf temperature difference control irrigation system.
Background technology
The traditional paddy rice of China be all with soil whether lack of water irrigate for standard, rice field is anhydrous just pours water; Irrigation method, based on drowned rice field, adopts water layer to irrigate at rice transplanting to each ripe period; The degree of depth of water layer is different according to different regions, paddy rice type and growthdevelopmental stage, generally at 3-5cm.This irrigation method root system development is poor, easily lodging, early ageing, and ripening rate is not high, and sick worm is many, the not high shakiness of output, and efficiency of water application is low.Over nearly 30 years, along with industrial development and domestic water increase, the situation of water resource anxiety manifests day by day, China Study On Rice g and D to the susceptibility of moisture and improve water use efficiency basis on, sum up and propose the irrigation technique of the rice water-saving high yield of suitable different ecological environmental applications, and drip irrigation, infiltrating irrigation irrigation method.
In these Irrigations and Water-saving Cultivation Technique for Rice, play important function for the Rice Production under the not enough condition of water resource.But these Irrigations all need to irrigate with engineering to match, if there is no irrigation canals and ditches, there is no irrigate band, there is no cistern, be difficult to the object reaching water saving, irrigation water using efficiency or low, or water saving but cause that output is huge to be subtracted.Blade is the most important photosynthetic organs of paddy rice, is the main source of rice dry matter accumulation.Blade is the most important door of material between plant and external environment, energy exchange, and therefore the change of leaf temperature is with leaf water is rising, CO2 absorbs, it is closely related to store.Blade accepts solar radiation, and temperature rises gradually, consumes portion of energy, realize the adjustment of own temperature by transpiration effect.If there is water deficit, then transpiration rate reduces, and the energy consumed reduces, and leaf temperature also increases thereupon.Therefore the gas leaf temperature difference can reflect rice water situation, thus can be used for water deficit diagnose, instruct Crop Water-saving Technology to irrigate.So provide a kind of infrared radio temp. and humidity to transmit, very necessary and measure convenient and simple according to rice leaf temperature difference control irrigation system, instruct Crop Water-saving Technology to irrigate, prepare reliable, water-saving result is obvious.
In the management of peasant's common aqueous, ubiquity directly to be discharged water irrigations by irrigation canals and ditches, but spill often, and rice field is in long-term waterflooding state, and it is excessive to irrigate moisture input, causes the significant wastage of water resource.In rice water-saving irrigation technique the application of these water-saving irrigation techniques such as moistening irrigation, intermittent irrigation, Dry-wet alternate irrigation, film mulching cultivation for the reduction irrigation of paddy fields water yield, improve water use efficiency and serve obvious facilitation, but the conventional measure that the Dry-wet alternate irrigation of routine (also claiming intermittent irrigation) is irrigated as rice water-saving, duty can be reduced and improve efficiency of water application, but do not consider the physiological water requirement of paddy rice, if as the booting of paddy rice and heading flowering period fall to doing, can reduce effective fringe and thousand kernel weight, rice yield is not high; And these water managements are very large with the probability of the technology of being preordained, if do not have the supporting of good ambient weather and irrigation canals and ditches engineering, and very large manpower carries out meticulous management, and water saving is difficult to reach.The sprinkling irrigation of existing farmland water-saving irrigation pattern, drip irrigation economize Be very effective, but due to irrigation installation cost high, sprinkling irrigation drip irrigation be not suitable for spread in Rice Production.
Flood irrigation in the current Rice Production of China, causes the significant wastage of water resource.In rice water-saving irrigation technique the application of these water-saving irrigation techniques such as moistening irrigation, intermittent irrigation, Dry-wet alternate irrigation, film mulching cultivation for the reduction irrigation of paddy fields water yield, improve water use efficiency and serve obvious facilitation, but do not fully take into account the physiological water requirement of paddy rice, economize on water but cause rice yield not high; And these water management technology do not have the supporting of good ambient weather and irrigation canals and ditches engineering, and very large manpower carries out meticulous management, and water saving is almost difficult to reach.The sprinkling irrigation of existing farmland, drip irrigation economize Be very effective, but due to irrigation installation cost high, sprinkling irrigation drip irrigation is not suitable for spread in Rice Production.Therefore, need directly practical irrigation method to solve to irrigate to take a lot of work, the problem of time-consuming and waste water resource.
