Problems solved by technology

Therefore, the nitrogen applied to the soil as a seed fertilizer is lost after leaching of irrigation water and denitrification, which not only increases the production cost of farmers but also causes pollution of nitrate nitrogen and nitrite nitrogen in underground drinking water sources.

Embodiment 1

[0029] In 2010 / 2011, it was carried out in the experimental field of Fenghuang Town Agricultural Technology Station, Linzi District, Zibo City. The land has irrigation conditions. Sowing on October 8, the next day, the control plot and nitrogen-enriched treatment (three repetitions) were determined in the plot, and the nitrogen-enriched treatment was ditched and high-nitrogen compound fertilizer 22 N -10 P -12 KSOP (Potassium Sulphate) 900g. When the number of tillers per plant, the dry matter of the aboveground part, and the leaf color (SPAD value) were investigated during the greening period, it was found that the difference between the blank control and the nitrogen-rich plot was not obvious, so there was no topdressing. There were differences in the number of tillers, aboveground dry matter, and leaf color (SPAD value) at the jointing stage (Table 1), and the high-nitrogen compound fertilizer was topdressed at the jointing stage in the control plot and the field 22 N -1...

Embodiment 2

[0035] In 2012 / 2013, it was carried out in the experimental field of Crop Research Institute of Shandong Academy of Agricultural Sciences. The land has irrigation conditions. Sowing on the 12th, the third day in the plot identified the control plot with nitrogen-enriched treatment (three repetitions), nitrogen-enriched treatment with high-nitrogen compound fertilizer 22 N -10 P -12 K The amount of SOP (potassium sulfate) applied is 900 grams. When investigating the number of tillers, aboveground dry matter, and leaf color (SPAD value) at the turning green stage, it was found that the blank control was significantly different from the nitrogen-rich plot, so topdressing with high-nitrogen compound fertilizer 22 N -10 P -12 K SOP (potassium sulfate) 10 kg / mu. During the investigation at the jointing stage, it was found that there were still differences in the above-mentioned survey indicators (Table 2). N -10 P -12 K SOP (potassium sulfate) 8 kg / mu, see Table 2 for detail...

Abstract

The invention belongs to the technical field of nutrient management in a wheat production process, particularly relates to a management technology capable of improving the utilization efficiency of a nitrogenous fertilizer for wheat by optimizing the nitrogen application rate, the nitrogen application period and the fertilizer application position, and matters needing attention of the management technology, and concretely provides a soil basic fertility-based efficient application method of the nitrogenous fertilizer for wheat in a Huang-Huai-Hai wheat growing region. The current situation is greatly improved by fully utilizing the soil basic fertility; the accurate wheat nitrogenous fertilizer management can be guided by setting a blank block and a nitrogen-enriched block in the parcel; after the method is adopted, the utilization efficiency of the nitrogenous fertilizer can be effectively improved, the production cost of the wheat is lowered while the ecological environment is protected, and the comparative benefit of grain production is improved; the method has the characteristics of being simple and easy to operate and obvious in effect.

Description

technical field [0001] The invention belongs to the technical field of nutrient management in the wheat production process, especially the management technology and precautions for improving the nitrogen utilization efficiency of wheat by optimizing the amount of nitrogen applied, the period of nitrogen applied and the location of fertilization, specifically based on the basic soil fertility of North China High-efficiency application methods of nitrogen fertilizer in regional wheat. Background technique [0002] Wheat is one of the three major food crops in my country and the main crop in the North China Plain. Since the 1980s, my country's wheat production has increased significantly due to the increase in irrigated area and the application of nitrogen fertilizers. Farmers have changed from resisting chemical fertilizers at the beginning to applying large amounts of chemical fertilizers later. In the actual production of farmers at this stage, nitrogen fertilizer is genera...
