Nutritional raw soil curing agent for newly built terrace

Abstract

The invention discloses a nutritional raw soil curing agent for a newly built terrace. The curing agent comprises the following components in parts by weight: 20 to 25 parts of water holding agent, 40 to 45 parts of soil curing agent, 30 to 35 parts of humic acid raw material and 3 to 5 parts of medium trace element. The soil curing agent can hold the moisture of soil, increase organic substancesof the soil, improve the physical performance of the soil and create and culture a good soil environment for crop growth, and has broad application prospect in the newly built terraces of arid and semi-arid areas and similar soil.

Description

technical field [0001] The invention relates to a nutrient-type raw soil curing agent for newly built terraced fields, in particular to a soil curing agent for fast curing and improving fertility of newly built terraced fields. Background technique [0002] The area of ​​sloping cultivated land in Northwest China is large, and drought and soil erosion are serious, which are the main obstacles affecting agricultural production in this region. Repairing horizontal terraces is an important measure to maintain water and soil and improve land productivity. Changing sloping cultivated land into horizontal terraces can change the external shape of cultivated land, effectively prevent soil erosion, create a good water and soil ecological environment, and increase crop yield. However, with the expansion of the terraced fields, the soil of the terraced fields is exposed and the soil structure is destroyed due to the disturbance of large machinery. The newly built terraced fields show ...

Problems solved by technology

However, with the expansion of the terraced fields, the soil of the terraced fields is exposed and the soil structure is destroyed due to the disturbance of large machinery. The newly built terraced fields show poor soil structure, large volume, low organic matter content, lack of nitrogen and phosphorus, and poor permeability. Poor water and fertilizer retention performance, low and unstable yields have become the bottleneck for the further development of dry farming agricultural production. Therefore, it is necessary to quickly fertilize and mature the soil so that newly built terraces can increase production and income in a short period of time.

[0003] The commonly used fertilization measures are mainly to increase the application of organic fertilizers and replant crops that are resistant to barrenness. The fertilization and ripening effect is not good, and the soil curing agent products specially for newly built terraces are rarely reported. The nutrient-type raw soil curing agent for newly built terraces that integrates water retention and fertilization has important practical significance for increasing crop yields and rapid fertilization of newly built terraces, and at the same time, it can speed up the sustainable development of dry farming agriculture, promote agricultural efficiency, and increase farmers' income. And the rapid development of soil and water conservation ecological construction will play an active role in promoting
