Abstract

The invention relates to the technical field of agriculture, in particular to a northern cold area rice well water irrigation temperature increasing system and an irrigation method. One end of a wateroutlet pipe is connected on a pipeline on a water pump, the other end of the water outlet pipe is sealed, a plurality of holes are formed in the water outlet pipe, the water outlet pipe is mounted ona water dispersal plate, a water outlet position of the water dispersal plate is connected with a sunning water pool, an irrigation canal is arranged between the sunning water pool and a rice field,a temperature increasing shed is arranged on the irrigation canal, a water inlet and a water outlet are formed in two sides of the rice field and connected with a water inlet canal and a water outletcanal, and the water inlet canal is connected with the irrigation canal. According to the system, a water storage device, a water transmission process and the irrigation method are optimizes, the temperature of water is improved to 16 DEG C or more from 8-10 DEG C at a well head when well water enters the rice field, physiological requirements of rice for moisture and temperature are met, growth period process of the rice is accelerated, effective tillering rate is increased, head sprouting in a safe head sprouting period is ensured, maturing rate is increased, thousand seed weight is improved, yield-increasing effect is remarkable, average increase yield is 7% or more, and an economic benefit value is increased by 1500 Yuan per hectare.

Description

technical field

[0001] The invention relates to the field of agricultural technology, in particular to a rice well water irrigation and warming system and an irrigation method in the northern cold region. Background technique

[0002] Northern my country is an alpine region with long sunshine, short growth period and low effective accumulated temperature; slow temperature rise in spring, short high temperature period in summer, rapid temperature drop in autumn, and frequent low temperature and chilling damage are the primary factors restricting rice growth and development, stable and high yield; The eternal theme of rice cultivation in the northern cold region.

[0003] Rice is a temperature-loving crop. Studies have shown that the physiological critical temperature of rice plants is 16°C. When the ambient temperature is lower than this temperature, rice plants will stop growing; the impact of temperature on rice growth and development is manifested in two stages. One is rice...

Embodiment Construction

[0017] Below in conjunction with embodiment the present invention is further described in detail.

[0018] Such as figure 1 As shown, the rice well water irrigation and warming system in the northern cold region includes an outlet pipe 1 and a drying pool 3. One end of the outlet pipe 1 is connected to the pipeline on the water pump, and the other end is sealed. The outlet pipe 1 is installed horizontally and distributed on the outlet pipe 1. There are multiple holes; the water outlet pipe 1 is installed on the water diffuser 2, and the water outlet of the water diffuser 2 is connected to the drying pool 3, and there is an irrigation canal 4 between the sun drying pool 3 and the paddy field, and the irrigation canal 4 is provided with Warming shed; water inlet 10 and drainage outlet 8 are respectively provided on both sides of the rice field, and the water inlet 10 and the drainage outlet 8 are connected to the water inlet 9 and the drainage canal 7 respectively; the water inl...
