Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for preparing a one-time basal fertilizer for flue-cured tobacco. Background Art

[0002] Grapes are an important fresh fruit and processing raw material. Grapes are not only delicious, but also have high nutritional value. The sugar content of ripe berries is as high as 10%-30%, mainly glucose. The various fruit acids in grapes help digestion. Eating more grapes can strengthen the spleen and stomach. The resveratrol in grape skins and the proanthocyanidins in grape seeds are higher than other parts of grapes and most other fruit trees. They have extremely high medicinal value and have become an important nutritional and medicinal commodity in the world. Wine is the most important processed product made from grapes. Wine has become a high-grade consumer product due to its cultural connotations. In China, its consumption is rising sharply. The newly developed grape seed oil is used abroad as a high-end nutritional oil for infants and the elderly, and a high-end health oil for high-altitude workers and pilots, and has attracted much attention from the world. In 2021, the global grape planting area is about 7.3 million hectares (including fresh grapes and processed grapes for making wine, grape juice, and raisins). China's grape planting area ranks third in the world, about 783,000 hectares. In 2018, the output reached 13.667 million tons, making it the world's largest grape production country. China is the world's largest producer and consumer of fresh grapes, and the grape industry has become a pillar industry of agriculture in many places. .

[0003] In production, the application of quick-acting nitrogen fertilizer is generally recommended to be applied in batches, but some fruit farmers are eager to pursue production and often apply excessive nitrogen fertilizer, which not only causes problems such as waste of resources and environmental pollution, but also makes the fertilizer effect unclear or lacks fertilizer in the later stage due to unreasonable fertilization. Therefore, reasonable fertilization is the nutritional guarantee for the normal growth and high-quality and high-yield of grapes. In grape management, it is easy to ignore the importance of medium and trace elements to tree growth. Long-term and large-scale application of macronutrient fertilizers will lead to soil nutrient imbalance, coupled with improper management, which seriously hinders the rapid development of the grape industry. Long-term non-application of nitrogen fertilizers will lead to insufficient nutrient supply to the tree. Long-term application of pure fertilizers will lead to problems such as soil compaction and soil salinization. Therefore, a one-time basal application method of flue-cured tobacco fertilizer is needed to improve the above problems. Summary of the invention

[0004] In order to solve the problem of applying quick-acting nitrogen fertilizer in production, it is generally advocated to apply it in batches, but some fruit farmers are eager to pursue yield and often apply nitrogen fertilizer excessively, which not only causes problems such as waste of resources and environmental pollution, but also makes the fertilizer effect unclear or lacks fertilizer in the later stage due to unreasonable fertilization. Therefore, reasonable fertilization is the nutritional guarantee for the normal growth and high-quality and high-yield of grapes. The importance of medium and trace elements to the growth of trees is easily overlooked in grape management. The long-term and large-scale application of macronutrient fertilizers will lead to soil nutrient imbalance, coupled with improper management, which seriously hinders the rapid development of the grape industry. Long-term non-application of nitrogen fertilizers will lead to insufficient nutrient supply of trees, and long-term application of purified fertilizers will lead to problems such as soil compaction and soil salinization.
