Embodiment 1

[0011] Embodiment 1: organic chelated iron 15% former powder 2kg, selenium inorganic compound sodium selenite 0.7kg, fly ash 90kg, coal cinder fertilizer 150kg, Folium Isago 1000kg, cassava leaf 500kg, mixed retting makes selenium-rich base fertilizer, For 1 mu of dosage. Evenly spread and bury in the soil during site preparation; take 1 part of sodium selenite, an inorganic compound containing selenium, and dissolve it in 75 parts of Chinese medicine extracts of Atractylodes macrocephala, Codonopsis pilosula, barley, angelica, Fuqin and wolfberry with a concentration of 11%. The selenium-enriched foliar fertilizer is made, and the dosage is 1 time per mu, which is sprayed on the corn leaf surface at the early stage of corn pollination; and sprayed once more in the early stage of corn budding as above. If it rains after each spraying, respray once in time.

Embodiment 2

[0012] Embodiment 2: organic chelated iron 15% former powder 5kg, selenium inorganic compound sodium selenite 1.1kg, fly ash 100kg, coal cinder fertilizer 250kg, Folium Isatidis 800kg, cassava leaf 700kg, mixing retting makes selenium-rich base fertilizer, For 1 mu of dosage. Evenly spread and bury it in the soil during site preparation; take 1 part of selenium-containing inorganic compound and dissolve it in 90 parts of 14% concentration, and make a rich Selenium foliar fertilizer is applied once per acre and sprayed on the corn leaves at the early stage of corn pollination. In the early stage of corn budding, spray again according to the above method. If it rains after each spraying, respray once in time.

Abstract

The invention discloses a formula fertilizer for improving the corn yield. Before corn seedlings are transplanted, a selenium-rich base fertilizer is applied in corn land. The selenium-rich base fertilizer is prepared by mixing and wet-composting raw 15% organicchelate iron powder, an inorganic selenium compoundsodium selenite, pulverized fuel ash, a coal residue fertilizer and green manure and is uniformly applied to turned-over soil during land preparation. A selenium-richleaf fertilizer is respectively applied at an early corn pollination stage for one time. The selenium-rich leaf fertilizer is prepared by dissolving a selenium-containing inorganiccompoundsodium selenite in traditional Chinese medicine leachate. Corns uptakes a selenium element from nutrients in the growth and development process for multiple times, meanwhile corn roots are developed, the number of seedlings is increased, buds and spikes are full, and the pest and disease resistance capability is strengthened.

Description

technical field [0001] The invention belongs to a crop cultivation method, and relates to a formula fertilizer for improving corn yield. Background technique [0002] Selenium is one of the trace elements necessary for the human body. Insufficient selenium will reduce the immunity of the human body, affect people's quality of life, and even endanger people's health. To increase people's selenium intake, obtaining selenium from food is a broad and effective way. However, the selenium content in natural food is low, and it is difficult to meet the human body's demand for selenium. Therefore, it is necessary to increase the selenium content in food through human behavior. Corn is a staple food that the broad masses of our country like. To increase the selenium content of corn, we must start from the cultivation of corn, that is, add various inorganic selenium to the corn nutrition, and rely on the biotransformation process of corn growth to convert it into organic selenium, s...
