And fourthly, the yield and the quality of the planted crops are improved, sowing in autumn can be properly delayed or sowing in spring can be properly advanced, and the growth period of previous crops or the crops in the same season is prolonged, so that the yield and the quality are improved.
The advantages and background of the present device are explained below by combining data:
1. relationship between oblique and direct solar radiation and radiation intensity
1) Daily variation of incident angle
In fig. 8, AB is a ground plane, CO is a solar ray, DO is a solar ray at noon, FE is a direct light vertical line (ground slope forming line), and angle COD is angle AOF is slope angle S. The angle AOC is the incident angle alpha of the sun, the light CO is superposed with the ground plane AB when sunrise in the morning in one day, the incident angle alpha is 0 degree, the incident angle is gradually increased to the maximum (northern hemisphere) at the midday, and the sunset returns to 0 degree at night.
The ground sunshine intensity changes with the incidence angle alpha from zero radiation at 0 degrees in the morning to the maximum value at noon, and then gradually weakens to zero radiation at 0 degrees in the evening. Therefore, the sowing slope angle S is properly increased, so that the starting time point of direct solar radiation in the morning can be advanced, the finishing time point of direct solar radiation in the afternoon can be delayed, the direct solar radiation time is prolonged, and the over-high solar radiation in the afternoon is avoided, so that the advantage of the crop sunny slope sowing is enhanced.
The slope FE may be illuminated with the maximum angle of incidence of sunlight all the day when facing south, and may be illuminated with a smaller angle of incidence when facing east or west. The slope can obtain more solar radiation energy towards the true south (namely planting in the east-west row) than towards the east or towards the west (namely planting in the north-south row), so that the planting in the east-west row can play a greater role.
2. Seasonal variation of sun incident angle and sunshine duration
1) Variation of incident angle
The earth revolves around the sun in an elliptical orbit and rotates on its own axis, and the equatorial plane of the earth makes an angle of 23.5 ° with the orbital plane, the ecliptic plane, of the earth revolving around the sun, which is referred to herein as the declination angle.
In one year, winter solstice is about 12 months and 22 days, the sun is on the return line of south China, and the incident angle of sunlight in a northern hemisphere is minimum; the summer solstice is about 6 months and 22 days, and the sunlight incidence angle is maximum.
Taking the central points of Shijiazhuang (abbreviated as Shi) and Kuerle (abbreviated as Kurler) as examples, the solar incident angle alpha and the slope angle S are shown in the table 1 from winter to summer to noon of each month:
TABLE 1 mean noon solar incident angle in winter-summer-monthly
Note 1: the formula for calculating the solar incident angle is as follows: α is 90 ° -cos (30 ° × M) × 23.5 ° -W. Where α is the incident angle, M is the month, W is the latitude (38 ° 04 'north latitude of Shijiazhuang, 41 ° 45' coulter), and 23.5 ° is the ground axis declination angle.
Note 2: the slope angle S is 90-alpha
2) Change in sunshine duration
In spring equinox (
TABLE 2 sunshine time differences between Xia Zhishi Jiazhuang, Aksu, Kuerle and Shihezi at different latitudes
2. Determination of ground slope angle
When the sun is directly irradiated, the ground can obtain maximum radiant energy. According to the season and the daily solar incident angle, the solar slope with one side capable of being directly irradiated by the sun is created by adopting the mechanical device capable of adjusting the slope angle. If the Shijiazhuang is about 38 degrees in northern latitude, cotton is sown in the middle and late ten days of 4 months, and the sunny slope angle S should be about 26 degrees; the coulter adopts about 29 degrees in the same way.
3. Ground slope field monitoring result
The device is applied to field monitoring in Hebei Shijiazhuang in 3 months and 16-19 days in 2020 and in Xinjiang Korla in 4 months and 16-17 days in 2020. And monitoring the ground temperature of 5cm in the middle of the flat ground and the slope surfaces with different inclination angles of 25 degrees, 30 degrees and 35 degrees, and comparing the initial temperature rise time, the highest temperature, the lowest temperature, the daily average temperature and the daily accumulated temperature. Through comparative analysis, the temperature rise time is advanced, the highest temperature is higher, the effective accumulated temperature is obviously higher than that of the flat ground, and the temperature rise time and the daytime crop growth time are synchronous when the 5cm ground temperature of the slope surface is compared with that of the flat ground; the low temperature period is concentrated at night, and the lowest temperature is lower, so that the night metabolic consumption is reduced. Therefore, the sunlight slope sowing can more effectively utilize the light energy, and particularly can effectively promote the early seedling emergence and the growth and the strong seedlings of the cotton under the condition of lower temperature in the spring sowing period.
