The meaning of magnetic fertilizer
Magnetized compound fertilizer, referred to as magnetic fertilizer, refers to the combination of magnetic carriers with nitrogen, phosphorus, Potassium and trace elements are mixed and granulated in a certain proportion, and the fertilizer maintains a certain "residual magnetism" after being treated with a magnetic field. It is a new type of physical and chemical fertilizer that combines the advantages of physical fertilizers, chemical fertilizers and various compound fertilizers, plus unique magnetization technology. Magnetic fertilizers greatly increase the value of general compound fertilizers without increasing production costs (residual magnetism is equivalent to the yield-increasing effect of 5 nutrients), and they are effective in one season. ?
The yield-increasing mechanism of magnetic fertilizer
We know that the earth is a large magnetic field with a field strength of about 0.5 Oersted. All crops grow in this large magnetic field. Magnetism is one of the basic properties of matter. A former Soviet scholar conducted such an experiment and found that crops could not grow normally in a magnetic shielding device. This fully demonstrates that magnetism is beneficial to crop growth. ? When magnetic fertilizer is applied to the soil, it will form many micro-magnetic fields in the soil, which will directly affect the soil and crops. The existence of a large number of micro-magnetic fields enhances the micro-agglomeration of soil, reduces the specific surface area, and reduces the bonding force, thereby breaking up the hardening and loosening the soil; the existence of a large number of micro-magnetic fields regulates the magnetic environment for crop growth and improves the The ability of crops to absorb and transport nutrients has greatly improved the utilization rate of nutrients. The effect shown is that the magnetic properties are equivalent to about 5 nutrients. ?
Efficacy of magnetic fertilizer
Under equal nutrient conditions, magnetic fertilizer can increase yield by 5-15% with ordinary fertilizer. Compared with ordinary compound fertilizer, the good effects of magnetic fertilizer are mainly reflected in: The following aspects: (1) Improve the physical properties of the soil: it can reduce the soil bulk density, improve the soil micro-aggregate structure, increase soil water permeability, enhance soil drought and flood resistance, and increase ground temperature. ? (2) Improve the chemical properties of soil: it can reduce soil acidity, promote nutrient transformation, increase cation exchange capacity, reduce adsorption of soil phosphates, and increase adsorption of heavy metal ions. ? (3) Promote soil biological activity: It can increase the activity of soil phosphatase, invertase, amylase and hydrogen peroxide. ?In addition, magnetic fertilizer can also promote germination, growth and improve quality. Resistant to diseases and insects. ?
The application effect of magnetic fertilizer
The theoretical and applied research on magnetism in agricultural science has a history of several decades. Since the 1990s, magnetic fertilizer technology has been widely used in my country. With rapid promotion and application, magnetic fertilizer factories have sprung up all over the country. At present, nearly 100 magnetic fertilizer factories have been built. With the increasing expansion of magnetic fertilizer production, a large number of agricultural experiments and promotion work have been carried out across the country based on local soil and crop conditions. The situation in each place is briefly introduced as follows:? The Dezhou Experiment Station of the Chinese Academy of Agricultural Sciences has confirmed the effectiveness of high-efficiency magnetic fertilizers. Application effect: A field fertilizer efficiency test was conducted on wheat, corn, and cotton in the Yuanling County experimental area. The results are as follows: applying 50kg of magnetic fertilizer per mu, compared with the blank test and ordinary chemical fertilizer (12.5-15kg/mu of ammonium phosphate, 10-12kg/mu) Compared with urea per mu), the wheat yield increased by 27.6 and 10.9 respectively. Compared with the blank test, the corn yield increased by 33.8, and the income per mu increased by 30. ? The Soil and Fertilizer Institute of the Shaanxi Academy of Agricultural Sciences conducted two agricultural tests of magnetic fertilizers in the autumn of 1993 and the summer of 1994. Comparative tests were conducted using potted and field methods. The results are: for potted rapeseed, magnetized fertilizers are better than unmagnetized compound fertilizers with the same formula. The yield of potted wheat increased by 14.5%, which was 1.1 times higher than that of the blank sample; the yield of potted wheat with magnetization increased by 24.8%, which was 1.7 times higher than that of the blank sample; the yield of field rapeseed increased by 20.4% with magnetization, which was 1.9 times higher than that of the blank sample.
? Comparative tests of magnetic fertilizers and ordinary compound fertilizers on rice, corn, wheat, peppers, sugar cane, and tobacco conducted by the Soil and Fertilizer Institute of the Guangxi Academy of Agricultural Sciences showed that the application of 10-6-9 magnetic fertilizers is better than 10-10-10 domestic compound fertilizers and On 15-15-15, imported compound fertilizers increased the yields of rice and corn by 7,11.9 and 11.69,7.7 respectively; the yields of sugarcane and pepper increased by 8,9 and 7,8 respectively. ? A comparative test of equal amounts of fertilizers conducted by the Jiangsu Lianyungang Academy of Agricultural Sciences on corn, cabbage, melons, and peaches showed that the application of magnetic fertilizer (total nutrients 18) has the effect of increasing yields compared with the application of ordinary compound fertilizers (total nutrients 25) and diammonium. , the corn yield increase rate was 9.7%, and the sugar content increased by 12.8%. ? A pot experiment conducted by South China Agricultural University in Guangdong showed that the yield of rice using magnetic fertilizer increased by 28.6% compared with not applying magnetic fertilizer, and the yield increased by 11.8% compared with applying isotrophic ordinary chemical fertilizer. ? The spring wheat magnetic fertilizer test conducted by Shihezi Agricultural College and 149 Research Institute showed that using magnetic fertilizer as base fertilizer can increase spring wheat yield by 15 to 18%. ? The vegetable plot test conducted by the Agricultural Science Institute of Beijing Haidian District in the hot springs of this district shows that the application of magnetic fertilizer at 50 to 100kg/mu, of which 1/2 is base fertilizer and 1/2 is rosette bar, can increase the yield of Chinese cabbage by 9.5 to 21%. ? Yueyang Agricultural Science Institute conducted magnetic fertilizer tests at 15 points in the city and showed that compared with equivalent fertilizers, the yield increase range was 7.7 to 26.4. ? Under the three different soil types and local cultivation conditions of the Liaocheng Agricultural Science Institute, applying 50-75kg of magnetic fertilizer per mu can increase wheat production by 15-20%, cotton production by 10-15%, and adding additional magnetic fertilizer to corn can increase production by 16% ~18, up to 25 or more. ? In the Nanjing area where Nanjing soil is located, a plot test and a field comparative test were conducted on the application of fly ash to yellow-brown soil and paddy fields. When 5,000kg of fly ash was applied per mu, the wheat yield increased by 22.3%, and the grass crops generally increased by about 20%. At the same time, the pulverized coal In addition to increasing the yield of crops in the current season, ash also has certain after-effects. For example, test results in Jiangwa Village showed that the yield of rice in the current season increased by 17.8%, and that of wheat in the second season increased by 15.7%. ? From 1978 to 1981, Hubei Provincial Electric Power Bureau and other units planted wheat, rapeseed, rice and other crops in acidic red soil, lake soil and paddy soil in several areas of the province. They applied 150-250kg of magnetized fly ash per acre, which can make the crops The yield increased by 10 to 15%, especially for wheat and rapeseed. ? A comparative test was conducted in Xinyang area between magnetic compound fertilizer and ordinary fertilizer with equal nutrients. Wheat yield increased by 8 to 10%, rice yield increased by 10 to 13%, and rapeseed yield increased by about 10%. ? The results of the magnetic fertilizer test conducted by the Soil and Fertilizer Station in Leshan City, Sichuan were: the rice yield increased by 26.8%, which was 12% higher than that of the same formula and the same amount of fertilizer without magnetization. In 1995, a test collaboration group was formed at 13 magnetic fertilizer factories in Sichuan and conducted 50 tests. The results showed that the yield increased by 15 to 30% compared with the control. Compared with the same formula and dosage of magnetized fertilizer and non-magnetized fertilizer, the yield of magnetized fertilizer increased by about 7%. ?
In summary, the results of agricultural tests in various places and the effects of farmers using magnetic fertilizers over the years have confirmed that: ?
1. Magnetic fertilizers have a significant effect on increasing the yield of a variety of crops. ?
2. Magnetic fertilizers are generally better than ordinary compound fertilizers in terms of fertilizer efficiency and crop growth promotion. ?
3. The use of magnetic fertilizer is economical and cost-effective.
