Abstract
The invention discloses a selenium-containing microelement leaf fertilizer of a sweet potato, which comprises the following components: 16-18 parts of fulvic acid potassium, 7.5-8 parts of magnesium sulfate heptahydrate, 7-7.5 parts of zinc chelate, 9-11 parts of manganese sulfate tetrahydrate, 6.5-7 parts of ammonium molybdate tetrahydrate, 4.5-5.5 parts of copper sulfate pentahydrate, 12-14 parts of iron chelate, 8.5-9 parts of sodium selenite and 24-26 parts of monopotassium phosphate. During a swelling period of a root tuber of the sweet potato, when the selenium-containing microelement leaf fertilizer of the sweet potato is sprayed to a leaf, the dosage of the selenium-containing microelement leaf fertilizer of the sweet potato per 667m<2> land is 80g plus 30L water; and when the selenium-containing microelement leaf fertilizer of the sweet potato is sprayed for the second time by the same method after 15 days, the total dosage of the selenium-containing microelement leaf fertilizer of the sweet potato per 667m<2> land is 160g. The leaf fertilizer is rich in selenium microelement, so that after the leaf fertilizer is sprayed to the leaf of the sweet potato, the sweet potato is rich in selenium microelement.
Description
technical field [0001] The invention relates to a sweet potato leaf fertilizer, in particular to a sweet potato leaf fertilizer containing selenium and trace elements. Background technique [0002] At present, there are many kinds of sweet potato foliar fertilizers on the market. Sweet potato foliar fertilizers are nutrient agents developed according to the growth characteristics of sweet potato crops and their nutrient accumulation and transportation rules. They can effectively inhibit the rapid cell division of sweet potato aboveground parts and promote plant dwarfing. , reduce the excessive consumption of nutrients by plant growth, ensure that the plants are strong and not excessively long, the nutrition is balanced, the fruit expands quickly, increases the chlorophyll content, promotes the transfer of crops from vegetative growth to reproductive growth, and expands the fruit to greatly increase the yield. However, the current sweet potato foliar fertilizer Basically,...
