Four-dimensional saline-alkali soil improving method

Abstract

The invention discloses a four-dimensional saline-alkali soil improving method. The four-dimensional saline-alkali soil improving method comprises the following steps of S1, rearranging lands and mounting a field irrigation and drainage pipe network, sensors, a transmission system and a monitoring system; S2, preparing homemade fertilizer in a simple manner and increasing soil fertility in a greenand sustainable manner; S3, applying soil targeted conditioning agent to solve specific soil problems; S4, planting saline-alkali tolerant rice to combine biological improvement with agronomic measures. Through soil fertility increasing and by applying the soil targeted conditioning agent, the four-dimensional saline-alkali soil improving method can achieve comprehensive improvement of agronomiccharacters of soil and convert low-yield fields into high-yield fields, and unutilized fields to cultivable fields. Through comprehensive application of four-dimensional improvement, the four-dimensional saline-alkali soil improving method can achieve comprehensive improvement of saline-alkali degree of soil as well as improve the economic yield of crops.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a four-dimensional improvement method for saline-alkali land. Background technique [0002] In 2016, the world's population reached 7.26 billion, and current estimates show that the world's population will continue to grow in the next few decades. The pressure on the land to feed the population is increasing, and more arable land is needed to feed the world. growing population. [0003] However, the total amount of land is basically unchanged, and the purpose of cultivating can only be achieved by improving the non-cultivable land. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. Through the improvement of saline-alkali land, the physical and chemical properties of the soil can be improved, and a good growth and development environment can...

Problems solved by technology

In view of the problems existing in the prior art that the improvement of saline-alkali land has a low degree of intelligence, manual inspection and manual control of the irrigation system are required during irrigation, a large amount of human and financial resources are wasted, and an optimized irrigation scheme cannot be formed, resulting in a large amount of waste of resources. Through field irrigation and drainage The layout of infrastructure such as pipe networks, sensors, transmission systems, and detection systems has laid the foundation for the overall digitalization and intelligence of farmland
