Problems solved by technology

In recent years, in order to pursue high yield and high efficiency, growers have applied a large amount of chemical fertilizers, which has continuously damaged the soil structure, resulting in serious soil compaction and acidification.
However, the soil in the "potato-rice-rice" three-cropping area in the south is mostly acidic, and the application of a large amount of chemical fertilizers has accelerated the decline in soil fertility, land productivity, and fertilizer utilization, leading to a vicious cycle of increasing chemical fertilizer application. In the end, there will be a phenomenon of limited or even reduced output
In the prior art, a large number of methods such as applying chemical fertilizers and abandoning land are used to rapidly increase soil fertility, but these methods cannot meet the needs of not only delaying agricultural planting, but also not destroying the structure of the soil, nor can it achieve maintenance or even soil fertility. The need to increase soil fertility

Abstract

The invention discloses a method for rapidly fertilizing soil by using a potato-rice-rice rotation model. The method comprises the following steps: 1) planting winter potatoes: applying a base fertilizer and conducting three times of topdressing; 2) planting early rice: conducting twice topdressing and returning the whole amount of straw to the field; and 3) planting late rice: conducting three times of topdressing and returning the whole amount of straw to the field. The method can improve the soil nutrient property, rapidly increase the soil fertility, and rapidly fertilize the soil; at thesame time, the method can increase the crop yield, reduce application amount of chemical fertilizers, save production cost, and greatly improve planting efficiency.

Description

technical field [0001] The invention relates to a method for rapidly fertilizing soil, in particular to a method for rapidly fertilizing soil using a potato-rice-rice rotation pattern. Background technique [0002] To fertilize the soil is to make the soil fertile, maintain and improve the fertility level of the soil. In recent years, in order to pursue high yield and high efficiency, growers have applied a large amount of chemical fertilizers, constantly destroying the soil structure, causing serious soil compaction and acidification. However, the soil in the "potato-rice-rice" three-cropping area in the south is mostly acidic, and the application of a large amount of chemical fertilizers has accelerated the decline in soil fertility, land productivity, and fertilizer utilization, leading to a vicious cycle of increasing chemical fertilizer application. In the end, the increase in output is limited or even reduced. In the prior art, methods such as applying a large amount...
