Abstract
The invention discloses a coated slow-release fertilizer for potatoes. The coated slow-release fertilizer comprises the following raw materials according to the parts by weight: 2-6 parts of acetylcholin esterase, 3-7 parts of urease, 4-9 parts of o-phenyl phosphoryl diamine, 10-15 parts of a potato plant extract, 3-6 parts of a microbial agent, 30-40 parts of urea, 10-20 parts of monopotassium phosphate, 15-30 parts of potassium sulfate, 5-15 parts of borax, 10-15 parts of ferrous sulfate, 10-15 parts of zinc sulfate, 5-15 parts of sodium molybdate, 5-15 parts of magnesium sulfate, 12-18 parts of calcium superphosphate, 10-33 parts of carbamide, 10-30 parts of monoammonium phosphate, 0.1-1 part of manganese sulfate, 0.1-1 part of copper sulfate, and 5-10 parts of a binder. The potato plant extract is formed by a branch and leaf part extract, a stem part extract and a root part extract, wherein a proportion of the branch and leaf part extract, the stem part extract and the root part extract is 4:2:1 according to the parts by weight. The coated slow-release fertilizer is capable of improving the yield of the potatoes, improving the starch content and the crude protein content in thepotatoes, and reducing the content of soluble sugar.
Description
technical field [0001] The invention belongs to the field of fertilizers, in particular to a wrapped slow-release fertilizer for potatoes. Background technique [0002] Potatoes, also known as potatoes and yams, are perennial herbaceous plants of the family Solanaceae and annual herbaceous plants. Together with wheat, rice, corn and sorghum, they have become the top five crops in the world. Tubers are rich in starch, protein and minerals, and can be used as dishes, grains for human consumption, and can also be used as feed or other processing purposes. Potatoes have very strict requirements for nutrients. During the growth process, there is a correlation between the aboveground stem and leaf part and the underground tuber part. The growth of the aboveground stem and leaf part is the basis for the formation of yield. The tubers in the soil cannot get enough nutrition, and if the stems and leaves of the above-ground part grow too vigorously, they will compete with the tubers ...
