Composite fertilizer for potato

Abstract

The invention relates to the technical field of fertilizer, and concretely relates to a composite fertilizer for potato. The composite fertilizer is characterized by taking common urea, diammonium phosphate, potassium sulfate, monoammonium phosphate, potassium chloride, white copperas zinc sulfate, ammonium molybdate, sodium borate, fabriate calcium, single superphosphate and meerschaum as a base, and the above components are prepared to obtain the composite fertilizer for potato according to certain proportion. The composite fertilizer comprises the components by weight: 18-20 parts of urea, 15-17 parts of diammonium phosphate, 8-10 parts of potassium sulfate, 7-9 parts of monoammonium phosphate, 9-11 parts of potassium chloride, 7-9 parts of white copperas zinc sulfate, 7-9 parts of ammonium molybdate, 3-5 parts of sodium borate, 7-9 parts of fabriate calcium, 2-4 parts of single superphosphate and 3-5 parts of meerschaum The prepared composite fertilizer for potato is capable of greatly increasing potato weight per plant, plant height and potato starch content of potato as well as obviously increasing the potato output and quality.

Description

[0001] technical field [0002] The invention relates to the field of fertilizers, in particular to a special compound fertilizer for potatoes. Background technique [0003] Potatoes, also known as potatoes and yams, are second only to wheat and rape crops in planting area. Potato has high yield and wide application. It is a dominant crop for increasing agricultural efficiency and farmers' income, and it is also a high-yield crop for drought relief. With the development of the market economy and the constant adjustment of the agricultural planting structure, more and more attention has been paid to the potato production day, and the products have become popular year by year. [0004] How to improve varieties, improve fertilization techniques, increase potato yield and improve quality is an important issue in potato production. Fertilization is a very important link in potato production. However, no fertilizer formula and fertilization process for potatoes have been found i...

Problems solved by technology

Fertilization is a very important link in potato production. However, no fertilizer formula and fertilization process for potatoes have been found in the existing technology. Almost all potato growers apply fertilizer based on experience, not to mention that it may cause Soil compaction and soil erosion, in terms of the effect of fertilizers on potatoes, is not as good as expected, and there is a lack of a strict potato formula to guide people's fertilization
