Description

Technical Field

[0001] The present invention relates to the technical field of sowing equipment, and in particular to a method and a device for accurately supplying water to sow crops. Background Art

[0002] Drought and water shortage affect the sowing, emergence and yield of crops, and are important factors restricting the sustainable development of agriculture. At present, the average annual precipitation in 47% of my country is less than 400 mm, and the area of ​​farmland affected by drought each year accounts for 25% to 30% of the total cultivated land area. Corn, as one of the main food crops, has strong adaptability, wide distribution, multiple uses, and great potential for increased production. Its sown area and total output are second only to rice and wheat in the world, and it plays a key role in food security. The sowing period and emergence rate of corn largely determine the growth status and yield of corn. The emergence speed and emergence rate of corn are related to soil moisture and temperature. Especially in the northern region, corn requires a certain amount of irrigation to ensure emergence.

[0003] After corn is sown, it needs to absorb 48% to 50% of its absolute dry mass in water in order to swell and germinate. If the soil moisture conditions are not good, even if it can barely swell and germinate, it will often cause serious lack of seedlings due to its weak ability to emerge from the soil. If the soil has too much moisture and poor aeration, the seeds will easily rot, which will also cause lack of seedlings. This is especially serious under low temperature conditions. The root layer soil must be maintained at 60% to 70% of the field water holding capacity to ensure a good emergence rate.

[0004] After traditional sowing, irrigation water needs to be applied for seedling emergence. This irrigation method is usually based on ground irrigation, which is not only expensive but also has low water utilization efficiency, exacerbating the contradiction between water supply and demand. Especially in water-scarce areas, the contradiction between agricultural water use and food production is particularly prominent. Therefore, there is an urgent need for a sowing irrigation device and method that can ensure the smooth emergence of corn seedlings when water resources are relatively scarce.

The spray ring 405 and the first volume chamber 403 are in a connected state. Liquid is supplied to the first volume chamber 403 through the liquid supply channel 404, and water can be supplemented according to the situation during sowing. At the same time, this part can also be used separately as a nutrient solution adding part, that is, when the water storage pipe 5 sprays seeds and water, the spray ring 405 works at the same time to apply a certain amount of nutrient solution to promote seed growth.

[0062] A preferred embodiment, in combination with Fig.11 , Fig.12 , Fig.13 and Fig.15 As shown, a plurality of water outlet holes 406 are evenly arranged on the spray ring 405, and the interior of the spray ring 405 has a double-layer space, and each layer of space is connected with a corresponding number of water outlet holes 406.

At the same time, the air intake port of the second volume chamber 407 is located at the bottom surface of the displacement channel 401, at least flush with the bottom surface of the displacement channel 401, or lower than the bottom surface. The second volume chamber 407 has an air intake pipe 408 connected to the outside, and the air intake pipe 408 is connected to the negative pressure device through a pipeline to generate adsorption of the air around the tube 4 area to prevent dust from adhering to the spray ring 405 and causing adhesion and blockage. The air intake should be intermittent air intake, that is, when the tube 4 is working, the operation is stopped;

[0064] The air inlet can also be used for air outlet operation, because the air inlet shape of the second volume chamber 407 is basically a full circle ring. By generating a horizontal airflow toward the center, the liquid can be blown toward the center when the spray ring 405 is in operation, so that the moisture is more concentratedly distributed around the seeds.

[0065] A preferred embodiment, in combination with Figure 12-13 As shown, the pressure member 6 includes a thrust member 601 and a blocking cover 602; the thrust member 601 is fixed above the displacement channel 401, and a small hydraulic cylinder can be used.

During the pushing process, the air is pressurized inside, so that when the water storage pipe 5 moves to the specified position, the pressure is released instantly to quickly discharge the water and seeds, ensuring that they are smoothly delivered to the specified position and preventing the liquid from being too dispersed.

[0066] A preferred embodiment, in combination with Figure 5-9 As shown, the quantitative components 2 are arranged in pairs, and the quantitative components 2 include a box body 7 and a first turntable 8; a liquid inlet pipe 701 is provided on one side of the box body 7, and the liquid inlet pipe 701 is connected to the water storage bucket.

At the same time, a sealing ring 703 is provided in the middle of the box body 7, and the lower surface of the sealing ring 703 is flush with the lower surface of the liquid inlet pipe 701; the first turntable 8 is connected to the box body 7 by a rotating shaft, and a control motor is connected to the rotating shaft. A plurality of volume-adjustable storage cylinders 9 are provided on the first turntable 8, and the upper surface of the storage cylinder 9 contacts the lower surface of the sealing ring 703. The discharge pipe surface of the storage cylinder 9 contacts the upper surface of the bottom sealing ring 702, and sealing rings are installed at the ends to improve the sealing of the contact; by controlling the motor to drive the first turntable 8 to rotate, when the storage cylinder 9 is moved to the liquid inlet pipe 701, water flows into the storage cylinder 9, and quantitative storage is completed after filling. The structure is simple and stable, and will not be affected by vibration during the movement, thereby ensuring the accuracy of the water volume. It then continues to drive it to rotate to the water outlet pipe of the bottom sealing ring 702 to complete the transportation operation. At the same time, the arrangement of multiple storage cylinders 9 can realize circulating liquid supply, and each quantitative component 2 is connected to a corresponding supply channel 402.

[0067] A preferred embodiment, in combination with Figure 8 and Fig. 9 As shown, guide columns 901 are symmetrically provided at the bottom of the storage barrel 9, and positioning springs 902 are sleeved on the guide columns 901. A slidingly connected insertion piece 903 is provided on the guide columns 901, and the insertion piece 903 has multiple cylinders. The upper surface of the insertion piece 903 is connected to the positioning spring 902, and the storage barrel 9 is entered through the cylinder of the insertion piece 903 to realize the change of storage volume. The design is ingenious, wherein the surface of the guide column 901 is processed with threads, and the insertion piece 903 is pushed by rotating the nut to adjust the upward displacement.

[0068] A preferred embodiment, in combination with Figure 7 As shown, in order to realize automatic adjustment of the volume, a lifting member 704 is installed at the lower middle part of the box body 7, and the lifting member 704 includes a hydraulic cylinder 705 and a push ring 706; the bottom of the hydraulic cylinder 705 is fixed on the box body 7, and the push rod of the hydraulic cylinder 705 is fixedly connected to the push ring 706, and the edge of the push ring 706 is in contact with the insertion member 903.

This can speed up the discharge of the liquid. However, after the volume is adjusted, the position of the cylinder needs to be considered.

[0070] A preferred embodiment, in combination with Figure 3-4 As shown, the middle part of the tube 4 is connected to the bracket 102 through the elastic support member 10, so as to achieve angle support for the tube 4.

[0071] Experimental Example 1

[0072] Combination Figure 16-23 As shown in the experiment on the effect of water amount on seeds, this study was based on the Agricultural Ecosystem Experiment Station of Luancheng Agricultural Ecosystem Experiment Station of the Chinese Academy of Sciences located in the North China Plain, at 114°40′E, 37°50′N, 50.1m above sea level, with a warm temperate semi-humid and semi-arid climate. The average annual precipitation is about 440mm. The seeds selected were Dr. Bang 35C, the soil was tidal brown soil, the field water holding capacity was 30%, the wilting coefficient was 12%, the sowing depth was 5cm, and the sowing density was 4500 plants / mu.

[0073]

[0074] Table 1

[0075] As shown in Table 1, the experiment set up five seed irrigation treatments: T1: 30 ml, T2: 60 ml, T3: 90 ml, T4: 120 ml, T5: 150 ml. The mass of backfill soil in different experimental treatments was 12.5 kg. The background soil moisture content was the moisture content of the soil after air-drying (10.8%), simulating the soil moisture level under extreme drought conditions. Each treatment had five control replicates: CK1, CK2, CK3, CK4 and CK5. Figure 16-18 The comparison of water content, soil temperature and barrel planting quality after irrigation shows that the water content after irrigation in barrel planting experiments under different treatments slightly increases with the increase of irrigation amount, and the soil temperature does not change significantly. Fig.19 The dynamic changes of water content, soil temperature and barrel planting quality after irrigation. It can be seen that the T5 curve with the largest irrigation volume has the largest change range in the early stage, and all treatments gradually decrease with time. At the 37th day from sowing, all treatments tend to be unified. Fig. 20 This is the dynamic change of water content, soil temperature and barrel planting quality after irrigation. It can be seen that soil temperature is greatly affected by soil humidity, air humidity and weather. In the treatment with large amount of irrigation in the early stage, the soil temperature is generally low. In the end, after all the water evaporates, the soil temperature tends to be the same. Fig.21This is the dynamic change of water content, soil temperature and barrel planting mass after irrigation. It can be seen that the barrel load mass is the evaporation amount. The greater the amount of irrigation in the early stage, the higher the evaporation rate. As the distance to the sowing date increases, the evaporation rate tends to be more consistent. Fig. 22 The relationship between corn germination period, germination rate and water content shows that the length of corn germination period, germination rate and survival rate are significantly related to soil water content. As the root water content increases, the germination period shortens. When the irrigation volume is 150ml / grain and the soil water content is in the range of 10.8% to 11%, the germination days after sowing are 5-7 days, and the germination and survival rates can reach 100%;

[0076] When the irrigation volume is 120ml / grain and the soil moisture content is in the range of 10.2% to 10.8%, the germination days after sowing are 7-9 days, and the germination and survival rates can reach 100%;

[0077] When the irrigation amount is 90 ml / seed and the soil moisture content is in the range of 10.8% to 11%, the germination days after sowing are 9-19 days, the germination rate is 80%, but the survival rate is only 40%.

[0078] Fig.23 The root length and seedling height of corn on the 11th day after sowing with different irrigation amounts are as follows: the root lengths of T5, T4 and T3 treatments are 16 cm, 10 cm and 6 cm, respectively, and the corresponding seedling heights are 8 cm, 5 cm and 3 cm, respectively; experiments show that for corn, 150 ml of water is injected per seed each time in drought years, and 120 ml can be injected in wet years, which can meet the growth needs, and for corn, 150 ml of water is injected when the volume moisture content is below 20%, 120 ml of water is injected when the volume moisture content is 20-25%, 90 ml of water is injected when the volume moisture content is above 25%, and no water is injected when the volume moisture content is above 30%; therefore, through the technical solution, during the sowing process, the normal survival of corn can be guaranteed by relying on the quantitative addition of the corresponding amount of water by the device, effectively avoiding the waste of water resources by traditional irrigation methods, improving water utilization efficiency and germination rate, and irrigation can be carried out during the sowing process, simplifying the construction process, improving work efficiency, and effectively shortening the farming time.
