Problems solved by technology

But the effect is extremely poor. After emergence, the root system of the crop is still rotting rapidly, causing the seedling to die. This is mainly due to the fact that the commercial organic fertilizer is produced by fermenting organic waste and then drying and granulating at high temperature, which leads to the loss of enzyme activity of microorganism death and affects the rhizosphere environment, stress root growth, resulting in poor soil improvement effect

Embodiment 1

[0018] A soil improvement method, comprising the steps of:

[0019] a. Composting, fermenting and decomposing the organic material after crushing to obtain decomposed organic fertilizer;

[0020] b. Fully mix the decomposed organic fertilizer and phosphate fertilizer, evenly spread it on the leveled surface, and turn it into the soil. The amount of decomposed organic fertilizer is 800kg / mu, the amount of phosphate fertilizer is 50kg / mu, and the amount of phosphate fertilizer is heavy superphosphoric acid. Calcium meter. Preferably, before step a, the land is first subjected to salt discharge and desalination treatment measures, and the number of times of desalination and the amount of irrigation water are determined according to the salinity content of the soil. And mechanically prepare the uneven land to improve the overall salt drainage effect of the field.

[0021] The raw materials used in the commercial organic fertilizer involved in the present invention are the organi...

Abstract

The invention discloses a soil improvement method which comprises the following steps of: a, crushing organic materials and carrying out compost fermentation and decomposition to obtain decomposed organic fertilizer; and b, fully mixing the decomposed organic fertilizer with phosphate fertilizer, and evenly spreading the mixed fertilizer on a flattened ground and plowing soil, wherein the dosage of the decomposed organic fertilizer is 800-1500kg / mu and the dosage of the phosphate fertilizer is 50-100kg / mu. Through the method disclosed by the invention, the soil can be rapidly fertilized and the land capability can be improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method suitable for newly cultivated, abandoned and barren farmland soil in arid areas. Background technique [0002] In arid areas, newly reclaimed land, abandoned land, and farmland with poor soil generally have high salinity content, low organic matter content, and extreme shortage of soil phosphorus. As a result, the root system of the crops is easy to rot after emergence, and the seedling growth rate and seedling preservation rate are extremely low, which has no cultivation value. To this end, the soil needs to be improved to increase the seedling retention rate of crops. For this reason, someone proposes to improve the soil with commercial organic fertilizers in order to increase the seedling retention rate of crops. But the effect is extremely poor. After emergence, the root system of the crop is still rotting rapidly, causing the seedling to ...
