Problems solved by technology

However, only straw returning to the field cannot maintain the integrity of the nutrient cycle of the farmland ecosystem, and affects the nutrient supply capacity of the farmland soil, because after the crops are harvested, some nutrients will be taken away by the crop grains

Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] 1. After the corn was harvested, three pieces of farmland soil with a size of 3m×3m were selected as experimental plots, and the experimental plots were wheat-corn rotation crops. Create a closed cycle of nutrients in the farmland ecosystem on one piece of soil, and routinely fertilize another piece of soil, and the remaining piece of soil is used as a control.

[0024] 2. The three lands are dealt with as follows:

[0025] Create a closed cycle of the farmland ecosystem: (1) After the corn is harvested, weigh the corn grain yield of the farmland, which is 6kg; (2) measure the nitrogen content of the corn grain, which is 17g / kg; (3) calculate the corn grain yield of the farmland The total nitrogen content of the grain is 100g; (4) the nitrogen content of pig manure is measured, and it is 29g / kg; (5) ...

Abstract

The invention belongs to the technical field of land productivity enhancement and environment protection, and discloses a method for forming farmland ecosystem nutrient cycling integrity. The method comprises the following steps: 1) harvesting farmland crops, weighing crop grain yield; 2) detecting the nitrogen content of crop grain; 3) calculating total nitrogen amount of the crop grain; 4) detecting the nitrogen content of excrements of livestocks; 5) calculating application amount of the excrements of livestocks; 6) using the excrements of livestocks; and 7) totally crushing the crop straws for reclamation. The method forms the farmland ecosystem nutrient closed cycling, which solves the non integrity of the farmland ecosystem nutrient cycling due to man-made interference, continuous nutrient supply capability can be guaranteed for farmland soil, the law of nature can be perfected matched, cost is low, effect is high, and the method has environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of soil fertilization and environmental protection, and in particular relates to a method for shaping the nutrient cycle integrity of farmland ecosystems. Background technique [0002] The supply capacity of farmland soil nutrients is a key factor affecting crop yield. Due to human interference, such as crop harvesting, a large amount of nutrient elements are taken away, the nutrient cycle of the farmland ecosystem is no longer complete, and the nutrient content of the farmland soil is reduced, which affects the crop yield. In order to ensure the nutrient supply capacity of farmland soil, a large amount of chemical fertilizers and livestock and poultry manure are currently used in agriculture. However, due to the large amount of application, a considerable part of the nutrients are not absorbed and utilized by the crops, but enter the water body through seepage, runoff and other ways. Therefore, agricultur...
