Problems solved by technology

[0006] 1. The ratio of nitrogen, phosphorus and potassium fertilizers used in the existing summer corn fertilization technology is unreasonable
[0007] 2. The amount of fertilizer cannot meet the needs of corn well, and it is not easy to apply evenly
[0008] 3. The fertilization position is on the side of the corn, which cannot be well absorbed and utilized by the corn root system

Embodiment Construction

[0022] Below in conjunction with specific embodiment, further illustrate the present invention.

[0023] The Effect of Precise and Quantitative Fertilization on Summer Maize

[0024] (1) Test arrangement

[0025] The experiment was conducted from June to September 2013 in Liuzhai Village, Juqiao Town, Qibin District, Hebi City, Henan Province ("Hebi" for short) and Xuzhuang Village, Tangmiao Township, Yuncheng County, Heze City, Shandong Province ("Heze" for short). conduct.

[0026] There are 4 treatments in the test: precise fertilization (apply a 7.02g piece of fertilizer on each side of the two corn plants with an interval of 15cm between them, and the fertilization depth is about 10cm), customary fertilization (ditching and fertilization at the seedling stage about 15cm away from the plants and applying 50% nitrogen fertilizer And all phosphorus and potassium fertilizers, apply 50% nitrogen fertilizer in the middle of two corn plants at the silking stage, the fertilizat...

Abstract

The invention relates to a high-yield accurate and quantitative summer maize fertilization method. According to the fertilizer demand characteristic of the summer maize, a novel compressed sheet-shaped fertilizer identical in size and equivalent in the contents of nutrients including N, P and K, is developed and is applied in proper positions close to maize plants, as a result, the demand of the maize for nutrients is satisfied, and a fertilizer practice which can be used for increasing the yield and improving the utilization efficiency of the fertilizer is achieved.

Description

technical field [0001] The patent of the invention relates to a method for precise and quantitative fertilization of high-yield summer corn. Background technique [0002] As China's main grain crop, corn is an important raw material for food, feed and industrial industries. Since 2007, corn has become the crop with the largest planting area in China. During the growth period of summer maize, it has a strong ability to absorb fertilizer and needs a large amount of fertilizer. Scientific fertilization is a key technical measure to increase maize yield. Unreasonable fertilization phenomena such as heavy nitrogen fertilizers, light phosphorus and potassium fertilizers, blind selection of compound fertilizers with unreasonable nutrient ratios, "one shot" at the seedling stage, and shallow fertilization are common in current corn production, resulting in high fertilization costs, yield and economic Low benefit. On the other hand, due to the transfer of rural labor force, there i...
