Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 Shown, the method for effectively controlling soil phosphorus content that the embodiment of the present invention provides comprises the following steps:

[0063] S101: Reduce the amount of phosphorus fertilizer by half; or apply it every other year, that is, apply phosphorus in the first year, no phosphorus in the second year, and repeat the behavior of the first two years after the third year;

[0064] S102: Annual overall planning: According to the phospho...

Abstract

The invention belongs to the technical field of soil planting, and discloses a phosphate fertilizer application method and planting method for wheat-corn rotation. The phosphate fertilizer applicationmethod comprises the following steps: reducing phosphate fertilizer, namely performing application with half current dosage of phosphate fertilizer; or performing application every other year, namelyapplying phosphate in the first year, not applying phosphate in the second year, and repeating the behavior of first two years in the third year; and performing anniversary planning, namely controlling a phosphate application ratio for winter wheat to summer corn at 2:1 according to the phosphorus absorption regulation of two crops. According to the method, the nutrition of phosphate fertilizer is subjected to anniversary planning for winter wheat-summer corn two crops, and the soil nutrient pool is regulated and controlled, so that phosphate fertilizer can better meet the requirement of twocrops for growth and development, the input structure for fertilizer is optimized, the fertilizer utilization and soil organic matters can be promoted, the soil quality can be overall improved, and reference and basis are provided to establishment of farmland fertilization and rational farming system in double-cropping areas in the North China Plain.

Description

technical field [0001] The invention belongs to the technical field of soil planting, and in particular relates to a phosphorus fertilizer application method and a planting method for wheat-jame rotation cropping. Background technique [0002] In the past 30 years, with the large-scale application of phosphorus fertilizer, the amount of available phosphorus in the soil has increased rapidly, and the soil phosphorus pool has been surplus, and the efficiency of the applied phosphorus fertilizer has been very low or ineffective. Compared with the 1980s, the current soil phosphorus content in North China has increased significantly; while the existing fertilization technology schemes (or fertilization formulas) in my country are basically based on the consideration of the current crops, and do not fully consider the upper and lower crops of the rotation (annual situation) ) as a whole; did not consider the impact of climate (such as temperature, precipitation (which in turn affec...
