"I have 60 acres of tobacco leaves, each mu with 25 kg of ordinary compound fertilizer, 12.5 kg of polycarbon urea, and foliar spray with gold polycarbon 3 times. This year's tobacco leaf growth is significantly better than in previous years, and there are fewer diseases, and compared with traditional fertilization, the yield per mu of tobacco leaves is increased by 15-30%. Recently, at the "Henan Polycarbon Tobacco Planting Observation Activity" organized by Beijing Zhongnong Ruiliyuan High-tech Development Co., Ltd., Wang Jianxun, a tobacco planting expert in Pingdingshan City, reported his congratulations to the expert representatives who came to observe.

It can be seen intuitively from the tobacco field where polycarbon fertilizer is applied, and the tobacco leaves with polycarbon urea are large, the leaves are broad and thick, and most of the tobacco leaves are as long as an adult's arm.
Sun Liwen
Sun Liwen, the inventor of polycarbon fertilizer, who came to observe it in his nineties, looked at the harvest of tobacco leaves and said happily that the magical power of polycarbon urea is that it is not ordinary urea in the traditional sense, but a modified new type of urea, which has changed some defects of low utilization rate of ordinary urea and easy growth of crops. Under the action of polycarbon technology and enzymes, on the one hand, the product can collect carbon dioxide in the air, synthesize glucose with water under the action of sunlight, and then react with urea to produce proteins required by crops; On the other hand, it can activate various beneficial nutrients that are solidified in the soil for use by crops. Polycarbon technology allows tobacco leaves to produce more glucose, so that tobacco leaves grow stronger and thicker and larger.
The tobacco leaves grow uniformly, the leaves are thick, and each leaf is more than 20 pieces, more than two feet long and as many as one foot wide
Nie Jiangtao, marketing director of Ruiliyuan Henan, who was present, recalled that in 2019, polycarbon urea was harvested in the first test of tobacco leaf planting in Xiangcheng. Zhang Fu, a tobacco grower in Baita Temple in Wangluo Town, Xiangcheng County, took out 100 mu of tobacco fields for testing, using 50 kg of 15-15-15 compound fertilizer per mu as bottom fertilizer, 7.5 kg of polycarbon urea for top dressing, the whole process of topdressing 2 times, each mu of tobacco leaves sold more than 8,500 yuan, setting a high yield record in Xiangcheng that year. Later, with the strong cooperation of the team of Zhang Lingjun, general manager of Pingdingshan Polycarbon Fertilizer Operation Center's leading agricultural service company, polycarbon urea rapidly radiated from Xuchang City to Pingdingshan City, and in the past five years, the sales and users of polycarbon urea have increased rapidly.
The authoritative test report provided by the Quality Inspection Center of the Tobacco Research Institute of Henan Academy of Agricultural Sciences showed that the total sugar, reducing sugar and potassium indicators of tobacco leaf applied with polycarbon urea did increase significantly; Tobacco leaf nicotine, two sugar ratio, sugar base ratio, nitrogen base ratio, potassium chlorine ratio and other indicators are close to or meet the national tobacco requirements.
"This completely subverts the traditional concept that urea cannot be applied to tobacco leaf cultivation!" In this regard, Liu Jianan, an expert in tobacco service in Xiangcheng County, believes that the application of polycarbon urea on tobacco leaves can raise sugar and potassium, increase production and improve quality. "From these two data alone, polycarbon urea has great value in tobacco leaf promotion." For a long time, tobacco cultivation has used nitric acid nitrogen fertilizer and ammonium nitrogen fertilizer. The success of polycarbon urea experiments in tobacco planting is a complete subversion of the traditional theoretical urea that cannot be applied to tobacco leaf planting, and will be a revolutionary progress.
Sun Liwen, the inventor of polycarbon fertilizer, also said that urea has not been advocated or recommended for use in tobacco planting for a long time, because urea can not be directly absorbed by crop roots, urea is an amide nitrogen fertilizer, urea is applied to the soil, under the action of urease secreted by microorganisms, hydrolysis to form unstable ammonium carbonate, and then further decomposed into ammonium and carbon dioxide, mineral ammonium can be absorbed and utilized by crop roots in large quantities, and can also be adsorbed and preserved by soil micelles, and can be absorbed by roots after being converted into ammonium nitrogen in the soil. Due to the presence of polycarbon agent, polycarbon urea can supplement carbon, promote crop photosynthesis, produce more glucose, and increase crop yield and income. In addition, because polycarbon urea also contains a variety of activating enzymes, it can activate soil texture elements, activate soil beneficial flora, catalyze excess fertilizer that is not easy to digest and absorb by crops themselves (that is, phosphorus accumulated in the soil for many years and fixed), which is conducive to the balanced absorption of fertilizers by crops, and can also combine with water to form a molecular sieve, lock soil nutrients, and promote crop growth; It also increases stress tolerance and improves crop quality.
Su Yincai
Su Yincai, general manager of China Agricultural Ruiliyuan, said that polycarbon urea contains activated enzymes, which use "enzymes" to control the release of fertilizers and the absorption of fertilizers by crops, so that fertilizers have quick and durable effects. Although the amount of polycarbon urea is reduced, the yield of tobacco leaves can still be greatly increased, and the "double reduction" strategy that meets the requirements of tobacco production can reduce the amount of fertilizer, effectively improve soil compaction, reduce pesticide residues, and also contribute to the increase of total tobacco sugar, reducing sugar and potassium.
Su Yincai emphasized that polycarbon urea has been found in tobacco planting in Xiangcheng County, Xuchang City, and Pingdingshan City, through five consecutive years of scientific research experiments: First, weight loss does not reduce yield, the same amount of fertilization has high yield, excessive fertilization has a large yield. Second, the use of polycarbon fertilizer tobacco leaf disease is significantly reduced. After using polycarbon urea and then spraying gold polycarbon products, the disease resistance of tobacco leaves was significantly enhanced, and the medicine was reduced several times, saving labor and pesticide costs; Third, polycarbon urea can be used as bottom fertilizer or top dressing, and the effect of spraying gold polycarbon is better when the tobacco leaves are 10 leaves.
