Abstract

The invention discloses a soil conditioner for saline water irrigation of saline-alkali land facility vegetables. The soil conditioner comprises the following raw materials: 30-43% of inorganic calcium preparation, 15-28% of organic preparation, 20-33% of mineral preparation, 10-23% of additive, 7-20% of nutrient and 5-13% of steam reduction agent. After the soil conditioner for saline water irrigation of saline-alkali land facility vegetables is fertilized into soil, accumulation of salt in irrigation saline water in the soil can be reduced, sodium ions and chloride ions are promoted to be discharged out of the soil or even soil body at the crop root layer along with the irrigation water, the ratio of the sodium ions and the chloride ions in salt ion chemical components of the soil is reduced, the soil structure is improved, water retention and steam reduction are achieved, the soil permeability is increased, and meanwhile, the soil conditioner has significant effects on promotion of nutrient absorption and growth of facility vegetables, improvement of salt resistance, and improvement of the quality of the saline-alkali land facility vegetables.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a soil conditioner for salt water irrigation of vegetables in saline-alkali land. Background technique [0002] The development of facility agriculture in coastal areas is very rapid, but factors such as lack of fresh water resources and soil salinization have seriously affected the economic benefits of facility agriculture. Coastal facility agriculture is mainly the production of vegetables, flowers and fruit trees, especially the production of vegetables consumes a lot of water. Long-term dependence on underground freshwater resources has threatened ecological security. At present, excessive exploitation of deep underground freshwater has formed groundwater funnels in many places. The utilization of unconventional water resources such as saline water or recycled water is one of the feasible ways to alleviate the shortage of fresh water resources and restrain the further ...
