Embodiment 1

[0026] On December 15, 2015, the salty water in the shallow pond was pumped clean, and the mud pump pumped the pond mud to the middle of the field, so that the pond mud covering height of the field reached 10cm, and the covering amount was 40 square meters per mu, covering 3 fields Residential quarters, each with an area of ​​25 square meters. After 30 days of covering, the salt water in the shallow pond has completely frozen, and the ice thickness can reach about 15cm. On January 15, 2016, the salt water ice in the salt water pond was broken and transported to the Tangni community, and the ice was covered on the pond mud , the salt water ice salinity is 7.6g / kg, and the amount of ice cover is 40 m3 / mu. In addition, one of them was covered with pond mud plots to irrigate salt water and let it freeze naturally, wherein the irrigation volume of salt water was 40 cubic meters per mu, and the salt content was 7.6g / kg. On February 25, 2016, the salt water ice melted and infiltrate...

Abstract

The invention belongs to the technical field of agricultural production, and relates to the northern saline and alkaline land improving and fertilizing technology, in particular to a northern coastal saline and alkaline land rapid fertilizing method. The method includes the following steps that 1, salty pond silt is evenly put on the surface layer of soil; 2, the pond silt is covered with salt water ice; 3, after the salt water ice in the step 2 is melted and seeps, the surface layer of the pond silt is covered with a mulch; 4, the mulch is removed before spring sowing in the step 3, and a soil plough layer is turned to be uniform. The method has the advantages that aiming at the problems that after northern coastal saline and alkaline land is desalted physically, soil is barren, and productivity is low, a large amount of waste salty pond silt in the region is adopted as the raw materials, soil rapid fertilizing and structural improvement are achieved, and then the productivity, the utilization rate and the like of the land are rapidly improved. The method has remarkable economic, social and environmental benefits on the aspects of increasing the yield, improving the environment and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and relates to the improvement and fertilization technology of saline-alkali land in the north, in particular to a rapid fertilization method for saline-alkali land in the north. Background technique [0002] The shortage of fresh water resources in the Bohai Sea area, and the obvious adverse properties such as soil salinity, barrenness, and stickiness have seriously restricted the sustainable development of agriculture and the improvement of the environment in this area. [0003] In order to solve the invention patent, a method for improving saline-alkali land by natural freezing of brackish water (CN100479641C) and a method for improving saline-alkali land (CN101946573B) respectively disclose two methods for improving saline-alkali land. [0004] Although the above two methods have good effects on reducing salt and increasing soil moisture in saline-alkali soil, they have no obv...
