Special fertilizer for improving nutrition values of strawberries

Abstract

The invention discloses a special fertilizer for improving nutrition values of strawberries, and belongs to the field of fertilizers. The special fertilizer is concretely produced from urea, potassium fulvate, potassium dihydrogen phosphate, boric acid, calcium superphosphate, copper sulfate, magnesium sulfate, manganese sulfate, ferrous sulfate, zinc sulfate, calcium chloride, modified diatomite and a chelating agent. Substance components of the fertilizer are reasonably matched, so the content of vitamins in strawberry fruits is substantially increased, the vitamin A content is increased by 1.5-1.7 times, the vitamin C content is increased by 1.3-1.5 times, the vitamin E content is increased by 1.2-1.3 times, the content of potassium, sodium, magnesium, iron, calcium, phosphorus and other elements in the strawberries is high, and is not affected or slightly increased, the phenomenon of unable simultaneous increase of the content of all nutrient elements in traditional single fruit quality improving methods is improved, and the obtained strawberries have high nutrition values.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special fertilizer for improving the nutritional value of strawberries. Background technique [0002] In recent years, my country's strawberry industry has developed rapidly, bringing obvious economic and social benefits to the main production areas. In some areas, strawberry planting has also become a pillar industry in the local rural economy. By 2015, my country's strawberry planting area has reached 150,000 hectares, covering all parts of the country, with a total output of more than 2 million tons and an annual export of more than 120,000 tons of strawberries, becoming the world's largest strawberry production and processing exporter. [0003] At present, there are also systematic studies on strawberry fertilization technology in my country. Although most farmers have realized the significance of formula fertilization, there are not many actually applied to the use o...

Problems solved by technology

For various fruit plants including strawberries, if you want to increase the content of certain nutrient elements, you must increase the amount of fertilizer applied to this element, or increase the absorption rate of the plant for this element, but most elements usually have a strong relationship. For example, a moderate increase in the content of manganese can promote the increase of vitamin C content in the plant. If the increase is too high, it will not only reduce the content of vitamin C, but also reduce the content of iron and zinc. The interaction between each element is very complicated. , so it is still difficult to explore the research on the preparation of the corresponding fertilizers required to grow different quality fruits

In actual planting, it has been found that if the content of certain nutritional elements in the fruit is increased, it will have a negative impact on the rest of the elements. For example, various selenium-rich, iron-rich, zinc-rich and other fruits that have attracted people for many years, Although the content of its rich elements has increased, the rest of its own nutrients are mostly in a state of decline, resulting in problems such as nutritional imbalance and changes in taste quality. Such problems are also targeted and characteristic products for those skilled in the art. A barrier that needs to be overcome, the difficulty lies in the matching of various raw materials
