② agricultural magnetized water irrigation technique, wherein the single crop magnetized water irrigation is easy to absorb the nutrient and water by the crop, but the technique is in an open system environment, and is interfered by micro-topography, soil texture and material composition, groundwater and soil salinity, the controlled range of the magnetized water is relatively small, the distribution and the intensity are not uniform, so that the absorption degree of the crop to the nutrient and water is relatively non-uniform, and the growth of the crop is influenced as a whole;
③ the technology of magnetized water for crops and drip irrigation is that the magnetizer is installed in the relatively closed system of drip irrigation to integrate the irrigation technology of drip irrigation and magnetized water, which is not affected by the conditions of terrain, soil quality, etc. and is connected with the main, trunk and branch pipes seamlessly to save water and fertilizer, thus effectively promoting the dissolution of water to soil nutrients and minerals and the absorption of crops to nutrients and water, and improving the yield and quality of crops.

As shown in figure 1, a drip irrigation system is firstly arranged in a large-scale strip field planted for 1000 mu or so, and 3 to 4 land parcels (250 to 350 mu each) are controlled. A clarification tank 11 is dug for the drip irrigation system and a water pump 12 is installed to the side of the clarification tank 11. Then, the main pipe 2 is laid along the edge of the planting land, the main pipe 2 is connected with the water pump 12 through the magnetizer 15, in order to control the water outlet pressure of the water pump 12, a pressure controller 14 is installed on a discharge pipeline of the water pump 12, the pressure controller 14 can be a digital display type pressure controller and the like, meanwhile, in order to avoid the blockage of silt to the pipeline, a filter 13 is also installed on the discharge pipeline of the water pump 12, and the filter 13 is positioned at the upstream of the pressure controller 14; in addition, a fertilizer tank 16 is installed below the magnetizer 15 in order to add fertilizer to the magnetized irrigation water.

Example three: cotton field soil nutrient and soil moisture determination and comparative analysis of different irrigation treatment modes
a. Soil moisture content determination and analysis comparison of different irrigation treatment modes
Experiments of low-pressure small-flow cotton magnetized water drop irrigation high yield and resource efficient utilization technology in 2017 in the demonstration areas of Manus Bakka shops and six households of towns show that the water content of the measured soil is higher than that of the soil treated by CK (common water drip irrigation) in each key period of cotton growth and development (see Table 1). Wherein, in the cotton seedling stage (6 months and 3 days), the water content of the soil in the low-pressure small-flow magnetization area reaches 8.4 percent, which is 10.5 percent higher than that of the soil in the control area (CK treatment); in the cotton bud period (7 months and 11 days), the water content of the soil in the low-pressure small-flow magnetization area reaches 12.8 percent, which is 17.4 percent higher than that in the control area (CK treatment); in the cotton boll stage (8 months and 9 days), the soil water content in the low-pressure low-flow magnetized area reaches 9.1 percent, which is 15.2 percent higher than that in the control area (CK treated). The reason for the increased moisture content of the soil is that mineral crystals in the soil increase the osmotic pressure of the soil, thereby reducing the evaporation of water from the soil and thus leaving more water in the soil. The results show that: the water content of the soil can be effectively improved by magnetization treatment, and the improvement is most remarkable in a bud period in a monitoring period.
TABLE 1 comparison table of cotton soil moisture content between low-pressure small-flow magnetization zone and control zone
b. Soil nutrient determination and analysis comparison of different irrigation treatment modes
In the test, soil nutrients are measured before sowing and after harvesting, and the soil nutrients treated before sowing have similar contents as shown in table 2; after harvesting, the contents and reduction of organic matters, alkaline hydrolysis nitrogen, available phosphorus and available potassium in the low-pressure small-flow magnetization region are lower than those of contrast treatment; the reduction rates of organic matters, alkaline hydrolysis nitrogen, available phosphorus and quick-acting potassium in the low-pressure small-flow magnetization area are higher than those of contrast treatment. The reduction rates of organic matters, alkaline-hydrolyzed nitrogen, available phosphorus and quick-acting potassium in the low-pressure small-flow magnetization region are respectively increased by 15.5%, 19.2%, 30.1% and 4.5% compared with the control treatment. Research results show that the physiological activity of crop roots is enhanced to a certain extent by the magnetized water drip irrigation, and the absorption of nutrients in soil is accelerated, so that a foundation is laid for the final yield improvement of cotton crops.

Example four: determination and comparative analysis of cotton growth period form and mature period yield and quality in different irrigation treatment modes
c. Analysis and comparison of cotton growth conditions of different irrigation treatment modes
Firstly, randomly selecting a plurality of sample parties in the low-pressure small-flow magnetization region and the control region respectively in the test, wherein each sample party is 1 x 1m, 10 cotton plants are taken for each sample party for monitoring, and the number, the height and the stem thickness of the cotton plants are investigated and measured and recorded; then analyzing and comparing the difference of the growth conditions of the drip irrigation cotton in the low-pressure small-flow magnetized area and the control area of the three stages. Through comparative analysis of survey data (see table 3), the growth and development conditions of the cotton in the low-pressure small-flow magnetization area and the cotton in the control area are obviously different, the number of the cotton plants in the low-pressure small-flow magnetization area is 0.9-4.5 higher than that of the cotton plants in the control area in three periods, and the seedling protection rate is improved by 2.6-13.6%; the plant height of the cotton in the low-pressure small-flow magnetization area is 3.1-9.6 cm higher than that of the cotton in the control area in three periods, and is increased by 6.4-14.2%; the stem thickness of the cotton in the low-pressure small-flow magnetization area is 0.9-2.2 cm higher than that of the cotton in the control area in three periods, and is improved by 13.0-21.4%. Therefore, the cotton plants irrigated by the low-pressure small-flow magnetized water drops have higher seedling-keeping rate, thicker rootstock and better growth vigor than the cotton plants irrigated by the common water drops. The thick heel and stem of the cotton in the growth and development period of the cotton can well prevent the lodging phenomenon in windy days; the high seedling protection rate of the low-pressure small-flow magnetization area can lay a foundation for the improvement of the later cotton yield.

d. Yield analysis ratio of different irrigation treatment modes
In the near harvest period, a random sampling method is adopted in the test, a plurality of magnetized areas and non-magnetized areas for measuring yield are sampled randomly, 6 x 6m square frames are selected according to a planting mode to measure the number of plants and the number of bolls in a unit area, and the number of the stored plants and the number of single plant bolls per mu are determined; then, 20 bolls (upper, middle and lower cotton plants) are collected randomly according to different processing areas, dried in the air and weighed, and the average boll weight is calculated. The yield per mu of seed cotton is (kilogram/mu) harvest density (plant/mu) multiplied by the average single plant boll forming number (plant/plant) multiplied by the single boll weight (gram/boll)/1000 multiplied by a correction coefficient (85%); the yield per mu of ginned cotton is equal to the yield per mu of seed cotton multiplied by the lint (%). From Table 4, it is found that the yield components (excluding the weight per boll) of the magnetized water-dropped cotton field are all higher than those of CK (no magnetization) treatment. The number of plants per mu and the number of bolls of a single plant of the magnetized water drip irrigation cotton are respectively improved by 6.3 percent and 41.8 percent compared with the CK treatment; the yield per mu of the seed cotton subjected to the magnetized water drip irrigation reaches 384.7 kg/mu, which is improved by 42.9 percent compared with CK treatment; the yield of ginned cotton per mu reaches 157.7 kg/mu; however, the control treatment showed a higher single boll weight than the magnetization treatment because the number of bolls per plant and the number of plants per mu were significantly lower than the magnetization treatment. Comprehensive analysis, and the application of the magnetized water drop irrigation on cotton fields can greatly improve the yield of cotton and improve good technical demonstration for increasing both production and income of local farmers.

Example five: soil salinity change and desalination rate contrast analysis of different irrigation treatment modes
Tests show that (see table 5), the total salt content of the soil plough layer is reduced by each treatment, because the drip irrigation mode can wash and press salt on the soil plough layer, but the salt washing and pressing effect of the magnetized water irrigation on the soil plough layer is more obvious, and the reduction rate of the salt content of the soil subjected to the magnetization treatment is higher than CK (no magnetization). The reduction of the salinity in the soil is beneficial to the growth and development of cotton, the desalination rate of the magnetization treatment is 32.5 percent, and the desalination rate is improved by 30 percent compared with that of CK treatment; SO in soil4 2-、Cl-、Na+All the contents of (A) are reduced, and SO is magnetized4 2-、Cl-、 Na+The content reduction rates of (A) were 22.5%, 27.4% and 23.8%, respectively. Magnetic treatment of Na+The content of the compound is increased by 52.6 percent compared with that of CK. Shows that the magnetized water can accelerate the action of the Cl in the soil-、Na+And (6) leaching. The salt content of the soil is reduced because the structure of water is changed after the water is magnetized, the permeability and the activity of the water are increased, the migration of the water in the soil is accelerated, and the salt is pressed below a plough layer, so that the solubility of soluble salt in the plough layer is reduced, which is consistent with the test result. The reduction of the solubility of salt promotes the physiological activity of cotton to a certain extent, is beneficial to the absorption of nutrient substances and the accumulation of dry substances, and plays a beneficial role in increasing the yield and income of the cotton in the later period. K+Is a carrier for plant transportation of nutrients, Mg2+Is necessary ions for photosynthesis and green formation of leaves of plants, and can accelerate photoreaction. As seen from Table 5, the content of cations in the soil was decreased to some extent after irrigation, and the decrease rate of magnetization treatment was higher than that of CK treatment. The results show that: the magnetized water is used for irrigationEffectively promote the cotton root system to K in the soil+、Mg2+、Ca2+The absorption of the cotton can improve the physiological activity of the cotton, has promotion effects on the growth of the plant height of the cotton, the increase of leaves and the like, can accelerate photosynthesis, and has an important effect on the improvement of the yield in the later period.
