Problems solved by technology

At present, most of the crop-specific fertilizers sold on the market are produced for food or other economic crops, which are not suitable for the growth and development of Jerusalem artichoke. Applying these other crop-specific fertilizers or compound fertilizers to Jerusalem artichoke often results in damage to the seed buds and low yield. Shortcomings such as poor quality and poor quality have directly affected the production quality and industrialization development of Jerusalem artichoke

Abstract

The invention provides a special fertilizer suitable for jerusalem artichoke and application thereof, which belongs to the technical field of fertilizers. The special fertilizer suitable for jerusalemartichoke comprises the following components in parts by weight based on pure nutrients: 19-22.5 parts of nitrogen, 7-9.5 parts of phosphorus pentoxide, 8-10.7 parts of potassium oxide, 1.3-1.7 partsof magnesium oxide, 5-6.5 parts of sulfur, 1-2 parts of zinc and 10-16 parts of humic acid. Preferably, the fertilizer comprises 20 parts of nitrogen, 8 parts of phosphorus pentoxide, 10 parts of potassium oxide, 1.5 parts of magnesium oxide, 6 parts of sulfur, 1.5 parts of zinc and 10-16 parts of humic acid. By adopting the special fertilizer provided by the invention, the yield of the jerusalemartichoke tubers is increased, and the contents of total sugar, reducing sugar and synanthrin of the jerusalem artichoke tubers are increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a special fertilizer suitable for Jerusalem artichoke and its application. Background technique [0002] Jerusalem artichoke, commonly known as Jerusalem artichoke, is a perennial herb of the genus Sunflower in the Asteraceae family. It is native to North America and has been planted in China for nearly a hundred years. The stems and leaves above the ground are excellent livestock feed, which can reduce the use of antibiotics, improve the quality of meat, and improve the odor of feces in breeding places. Underground tubers are rich in inulin, accounting for about 70% of dry matter. Because inulin has many functions such as low calorie, lowering blood lipid and blood sugar, good water solubility, enhancing the proliferation of bifidobacteria, restoring gastrointestinal function, and enhancing calcium absorption, it is called "a representative typical diet in the 21st century"...
