In the 1990s, Xi'an University of Science and Technology doctoral supervisor and renowned geologist Professor Duanmu Heshun’s scientific research achievements “using potassium-rich rocks to make Wotian Jiafu Tian Special Fertilizer†aroused strong concern of senior people in academia and agriculture . Experts agree that this fertilizer is rich in silicon, calcium, magnesium, and potassium, and 38 kinds of trace elements and rare earth elements such as boron, zinc, iron, copper, molybdenum, manganese, titanium, and selenium. It will greatly benefit the improvement of soil aggregate structure, increase of soil effective nutrients, inhibition or degradation of harmful toxins in soil, and clean and healthy soil. In addition, this fertilizer also has four characteristics: green, organic, nutrition, and health care. After several inspections, demonstrations and communications, in 1994 the Huaxian Rongchang Potash Fertilizer Plant introduced this technology and used the abundant potassium-bearing trachytized rock resources of Hua County Jindui Molybdenum City to produce the first pure natural organic mineral fertilizer in China. Tianjia Special Fertilizer started the dream of "Making Stone into Gold".
In recent years, people have found that trace elements such as silicon, selenium, and titanium also have certain physiological functions and yield-increasing effects on crops. The "Wotada A" special fertilizer is rich in silicon, calcium, magnesium, potassium, and boron, zinc, iron, copper, molybdenum, manganese, titanium, selenium and other trace elements and rare earth elements.
We may wish to mention from silicon that silicon is an important component of crops. The oxides of seven nutrients such as silicon, phosphorus, potassium, calcium, magnesium, iron, and manganese account for about 80% of the average ash content, and the oxidation of silicon The material accounts for 14.2 to 61.4% of the ash content of the plant. After application of silicon fertilizer, the epidermis cells of the crops can be silicified. The stems and leaves can be upright and leaves can be reduced. The canopy photosynthesis can be increased by more than 10%, and the lodging resistance can be increased by about 80%. Japanese scientists have found that silicified cells can increase the disease resistance of plants, greatly reducing the incidence of powdery mildew, rust, rice blast, and leaf spot disease. Considering the outbreak of powdery mildew in the apple growing areas in Northwest China in recent years, it is inevitable that there will be no concern about the lack of silicon in fruit trees. According to statistics, 80% of China's cultivated land lacks silicon, 61% of the cultivated land lacks potassium, and the use of silicon fertilizer in soil has become a pressing problem. According to data, the application of silicon fertilizer can increase the root number of crops by 20-44%, increase the root length by 25-48%, increase the root weight by 21-75%, and restore the roots of debilitated and injured wounds. Heavy weight effect. Professor Cai Delong of Henan Agricultural University, known as the "Father of Chinese Silicon Fertilizer," believes that "silicon is a great innovation in agricultural production and has epoch-making significance."
Calcium is a necessary nutrient element for apple growth and development. Calcium deficiency shows water heart disease, bitter pit disease, and pox spot disease, and even fruit cracking, sunburn, yellowing of fruit heart, necrosis of fruit flesh, etc. Calcium deficiency is common and very common in apple production areas in China. serious.
Magnesium is a component of chlorophyll and is directly involved in photosynthesis and carbohydrate metabolism. Yellow leaf disease in fruit trees is related to iron deficiency and magnesium.
Potassium is a nutrient element of crops, and it is also a quality element and health-care element. Applying potassium fertilizer, the fruit tree is resistant to drought and cold, has good coloring, and has a high sugar content. The potassium contained in the “Wotada A†special fertilizer is cesium-soluble potassium, and its absorption and utilization rate is three times that of general chemical potassium.
The Nanjing Institute of Soil Science, Chinese Academy of Sciences investigated the contents of trace elements zinc, boron, manganese, molybdenum, copper and iron in the country. The results show that trace elements are lacking in different degrees in most areas of China. The middle and low-yield fields in China account for more than 70% of the total cultivated area, and most of them have the problem of lack of trace elements. "Wutada A" special fertilizer contains not only calcium, magnesium, but also contains trace elements such as boron, zinc, iron, copper, molybdenum, manganese, titanium, selenium, a fertilizer and more effects to solve a variety of physiological problems, to ensure the normal growth of fruit trees Development, high yield, quality and efficiency. “Wutada A†special fertilizer also contains 0.38% rare earth. Rare earth elements can not only enhance the crop's resistance to adverse environmental conditions, increase crop disease resistance, but also increase crop yield and improve crop quality. After using the grapes, the fruit size increased significantly, the ratio of sugar to acid increased, and the flavor improved. After the apple was used, not only the vitamin C content, total sugar content, and sugar-acid ratio of the fruit were increased, but also the fruit coloration and premature ripening were promoted. In addition, the application of rare earth can also reduce the accumulation of nitrate in fruits and vegetables, which is conducive to the production of pollution-free fruits.
Many friends of fruit farmers asked Professor Tian Jiaxuan of the Northwest A&F University. The content of special fertilizers for “Wotian A†is not very high. The functions of resilience, seedling strengthening, photosynthesis, disease resistance, and soil health care are very obvious. What are the better-labeled products on the market? Professor Tian Jiaxuan said that “Wotada A†special fertilizer is a genuine high-tech product, and its nutrition is very scientific, especially the effects of silicon and potassium are played incisively and thoroughly. Silicon, as a newcomer to crop nutrition, not only promotes the reproduction of plant germ cells, thickens cell walls and stiff branches due to the action of silicified cells, but also plays a role in resisting diseases and insects and lodging. At the same time, it can also promote the absorption and utilization of nitrogen and phosphorus, and enhance fertilizer efficiency. What's more important is that silicon can kill or adsorb the pesticide residues and harmful metals in the soil, and it has an irreplaceable role in cleansing the soil. The potassium of “Wutada A†special fertilizer is potassium oxide, the absorption rate is 98%, and the utilization rate is about 70%. Some people have summarized the advantages of the "Votianjia" special fertilizer, the unique "two reforms (improved soil aggregate structure, improve fruit quality"), "three high (high activity, high content, high absorption)", "four promotion ( Promote root, promote photosynthesis, promote coloring, promote early maturity), "five resistance (drought drought, cold resistance, insect resistance, lodging resistance, resistance to bacteria)" function, there is a strong increase in quality and production. Why does Xi'an Fruit Friendship Association vigorously promote Wutian A special fertilizer? Prof. Li Bingzhi, a famous expert on fruit trees, said: “Only the use of special fertilizer from Wotian A is the only way out of the fruit industry.â€
