- Abstract
In order to explore the fertilizer effect of appropriate application of organic fertilizers replacing chemical fertilizers and provide the thoretic basis for reduction of fertilizers, increase of efficiency, and high yield, in this experiment,Jingu 59 was taken as the experimental material, four fertilization modes including no fertilization, single chemical fertilizer application, single organic fertilizer application, and combined application of organic and inorganic fertilizer were designed to study the effects of the four different fertilization modes on the yield, economic benefits of millet from 2018 to 2020. The results showed that the agronomic efficiency of nitrogen, phosphorus, and potassium under single chemical fertilizer application was the highest among all fertilization treatments. Compared with no fertilizer treatment, the yield and economic benefit of millet treated with organic fertilizer alone increased, but decreased compared with the combined application of organic and inorganic fertilizer. Compared with no fertilization, the average nitrogen harvest index, phosphorus harvest index, and potassium harvest index of millet from 2018 to 2020 increased by 6.18%-28.67%, 16.90%-37.00% and 15.68%-32.49%, respectively. The average grain yield increased by 22.96%-65.09%. The average economic income increased by 3 522.5-8 982.8 yuan/ha. Among them, the treatment of combination of organic and half inorganic fertilizer had obvious effect of increasing yield and income compared with no fertilization treatment, increasing average yield by 44.65% and annual income by 5 389 yuan/ha. Considering from the aspects of fertilizer application amount, millet yield, and economic benefit, the combination of organic and half inorganic fertilizer treatment was the optimal combination of organic and inorganic fertilizers and could be recommended in the similar areas.
