Problems solved by technology
[0003] The total phosphorus content of calcareous soil is not low, but due to the strong ability of soil to fix phosphorus, this not only reduces the availability of soil phosphorus, but also easily fixes phosphorus in fertilizers, which greatly reduces the supply of soil to crops. Phosphorus capacity, to some extent limits crop yield enhancement
Therefore, how to properly activate the potential form of phosphorus in the soil is an important research topic for man-made regulation of soil fertility. The contradiction of insufficient resources has practical significance. In addition, due to the influence of high pH value, the availability of trace elements in the soil is very low, and with the application of high-concentration chemical fertilizers, the increase of yield, and the decrease of input of organic fertilizers, the occurrence of trace elements in crops The deficiency of elements is more and more common, and sometimes the lack of trace elements will become the limiting factor of crop yield, and even the grains will not be harvested in severe cases

Embodiment Construction
[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0011] A sulfur-based soil conditioner, comprising: phosphate fertilizer and sulfur powder. Among them, the phosphate fertilizer and sulfur powder can be adjusted according to the pH value and phosphorus content of the calcareous soil. According to the ratio of parts by mass, the phosphate fertilizer is 30-90 parts, the sulfur powder is 10-70 parts, and the sulfur powder is fruit tree sulfur powder. And the particle size of sulfur powder can be adjusted to adjust the speed of its biochemical action. The particle size is 200-600 mesh. The sulfur powder used as a modifier involves its oxidation in the soil. The oxidation process is: S0→S 2 o 3 2- →S 4 o 6 2- → SO 4 2- . The oxidation of sulfur powder in soil is realized through chemical and ...

Abstract
The invention discloses a sulfur-based soil improvement agent. The sulfur-based soil improvement agent is characterized by comprising the following components in parts by mass: 30-90 parts of a phosphatic fertilizer and 10-70 parts of sulfur powder. In the earlier stage and the middle stage of application of the sulfur-based soil improvement agent, the phosphorus content in calcareous soil can be directly supplemented through the phosphatic fertilizer, in the middle stage and the later stage, the pH value of the soil is regulated through the sulfur powder, then solidified phosphorus of the calcareous soil is released and therefore, absorption of crops to mineral element such as iron is regulated.
Description
technical field [0001] The invention relates to a sulfur-based soil conditioner. Background technique [0002] Calcareous soil refers to the general term for soil containing free calcium carbonate. It is widely distributed in arid and semi-arid areas between 10° and 40° north and south latitudes, accounting for about 1 / 3 of the world's land area. The distribution of calcareous soil in my country is also very broad. Due to the influence of high concentration of free calcium carbonate and high pH value, calcareous soil has a strong immobilization effect on phosphorus, resulting in a very low concentration of phosphorus in the soil solution and little mobility. Limiting factor for the growth of many crops. [0003] The total phosphorus content of calcareous soil is not low, but due to the strong ability of soil to fix phosphorus, this not only reduces the availability of soil phosphorus, but also easily fixes phosphorus in fertilizers, which greatly reduces the supply of soil ...
