Problems solved by technology

It can be seen that the fertilizer is mainly organic fertilizer, the proportion of chemical fertilizer is very small, and the content of available nutrients is very low, which cannot meet the requirements of NPK and other nutrients for the normal growth and development of green onions
[0007] In response to the above situation, in order to solve the problems of incomplete nutrient elements, unreasonable nutrient distribution ratio, inaccurate fertilizer dosage, inappropriate fertilization period, and inappropriate fertilization location in the fertilization of scallions, it is urgent to develop a method for the nutrient status of low-yielding sand ginger black soil in Huaibei. and fertilizer supply characteristics, in line with the nutritional characteristics and nutrient demand rules of scallions, which are conducive to increasing the yield of scallions, improving their nutritional quality, edible quality and safety quality.

Abstract

The invention discloses a Chinese onion field planting fertilizer suitable for Shajiang black soil, and a fertilization method thereof. The Chinese onion field planting fertilizer comprises, by weight, 15.0 to 25.0% of N, 12.0 to 16.0% of P2O5, 10.0 to 20.0% of K2O, 1.0 to 8.0% of SO4<2->, 0.5 to 5.0% of CaO, 0.2 to 1.0% of ZnO, and 0.5 to 3.0% of MgO. The Chinese onion field planting fertilizer is comprehensive in nutrient content, reasonable in nutrient combination, is capable of satisfying Chinese onion nutrient absorption rule requirements; the most advanced 4R nutrient management technology and additional fertilizer scientific fertilization method in the world are adopted, so that Chinese onion growth is promoted obviously, yield is increased, nutritional quality, edible local flavor,and safety quality are improved, farmer economic income is increased, fertilizer utilization rate is increased, nutrient loss is reduced, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a scallion planting fertilizer suitable for Shajiang black soil and a fertilization method thereof. Background technique [0002] Shajiang black soil is one of the three low- and medium-yielding soil types in the Huanghuaihai Plain in my country. The total area of ​​the country is as high as 60 million mu, mainly distributed in Anhui, Henan, Shandong and Jiangsu provinces. Anhui Province has the largest area of ​​Shajiang black soil, reaching more than 24 million mu, accounting for 41.5% of the total area of ​​Shajiang black soil in the country. Shajiang black soil is also the medium and low-yielding soil with the largest area in Anhui Province. According to statistics, Shajiang black soil accounts for 41.2% of the province's cultivated land area, 67.8% of the total dry land area of ​​Anhui Province, and 70% of the cultivated land area in Huaibei region. Shajian...
