Abstract

The invention provides a water-retaining agent used for saline-alkali soil soybean and containing straw powder raw material. The water-retaining agent comprises straw powder, crylic acid, acrylamide, ulva lactuca powder, laver powder, shrimp shell meal and sterculia lychnophora powder. The invention further provides application of the water-retaining agent to soybean planting in saline-alkali soil. The water-retaining agent has the advantages that the prepared water-retaining agent has high water absorbing capability in distilled water, tap water and NaCl solution with a concentration of 0.3%, the capability of water absorption in the distilled water can reach 800-950 times the weight of itself, the capability of water absorption in the tap water can reach 710-880 times the weight of itself, and the capability of water absorption in the NaCl solution with a concentration of 0.3% can reach 460-600 times the weight of itself.

Description

technical field [0001] The invention relates to a water-retaining agent for soybeans in saline-alkali soil containing straw powder raw materials and a preparation method thereof, belonging to the technical field of water-retaining agents. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. [0003] Now many people deal with straw by burning, but burning straw is extremely harmful. Increase the content of CO2 in the air, and the increase ratio of CO2 is far greater than that of burning ordinary trees; increase the inhalable particles in the air, wh...
