Problems solved by technology

Currently, the average light utilization efficiency of crops is less than 1%
[0011] However, within the high-stalk crop population, due to the impact of photosynthesis on CO 2 The absorption and blocking of the wind make the CO within the group 2 Concentration decreases, wind speed decreases, thus affecting photosynthesis
Since crop production is carried out under field conditions, various supplemental CO 2 Both methods have technical and cost problems that prevent them from being used

Embodiment 1

[0034] according to figure 1 The structure is connected with the device of the present invention, and erected in a cornfield with a plant height of 2.3m. The height of the stand 53 is 1.5 m. The double-control time switch 32 is set to turn on once every 15 minutes between 7:00-18:00 every day, and the turn-on time is 5 minutes. The device operates automatically. Select a sunny day with a wind force of 2 levels, and compare and analyze the cornfield without setting up the device of the present invention, and measure the CO at different heights inside the group respectively. 2 Concentration and wind speed, the data are shown in Table 1. The data during the air supply is the measurement data of the 3-5 minutes after the air supply, and the data after the air supply is the measurement data of the 5-10 minutes after the air supply is stopped.

[0035] Table 1 CO under the control of the device and when not using the device of the present invention at different heights within th...

Abstract

The invention relates to the field of agricultural machinery and provides a device for promoting CO2 complementation and air flow in a high-stalk crop community. The device comprises a solar energy photoelectric plate 11, a storage battery 12, an anemograph 21, a wind control switch 22, a photosynthetically active radiation photon list 31, a light control switch 32, a double time control switch 4, a motor-driven air blower 51, a blast pipe 52 and the like. According to the device for promoting the CO2 complementation and the air flow in the high-stalk crop community disclosed by the invention, the CO2 concentration in the crop community can be observably increased in or after a wind sending process, and the whole wind speed in the community can be observably raised in the wind sending process.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a method for promoting the internal CO of high-stalk crop groups 2 Supplementary and air flow devices. technical background [0002] For crops, photosynthesis is the main source of dry matter production, which accounts for about 90%-95% of the total dry matter of crops. The key to increasing crop yield is to increase the light energy utilization efficiency of crops. At present, the average light energy utilization efficiency of crops is less than 1%. According to the quantum efficiency of photosynthesis, the utilization rate of light energy can reach about 10%. Improving the photosynthesis of crops is an important means to increase food production. [0003] There are many factors restricting the photosynthesis of crops, among which CO 2 Concentration and wind speed are important factors restricting crop photosynthesis. Photosynthesis is the use of water and CO by green...
