Abstract

The invention relates to a crop protective agent for relieving Cd damage, a preparing method thereof and an application thereof. The crop protective agent for relieving the Cd damage is prepared from trehalose, calcium chloride and sodium nitroprusside. The invention further discloses the preparing method of the crop protective agent for relieving the Cd damage and the application of the crop protective agent to relieving influences of Cd on seed germination and seedling early-stage growing of crops. The crop protective agent for relieving the Cd damage is pertinently added in the seed germination process and the seedling growing process according to the Cd stress-response intervarietal difference of seed germination and the physiological basis of the Cd stress-response intervarietal difference, seed germination, root growth and sprout growth can be effectively promoted accordingly, the activity of amylase and the activity of antioxidant enzymes can be improved, the content of the Cd in plant bodies can be reduced, and bases and references can be provided for reasonably using Cd-contaminated soil, preventing early-stage damage to the crops and improving the safety of plants grown on the contaminated soil.

Description

technical field [0001] The invention relates to a crop protection agent for alleviating cadmium damage, a preparation method and application thereof, and belongs to the technical field of agricultural product safety. technical background [0002] Today's human social activities are frequent and promote the rapid development of industrial and agricultural modernization. However, the environment is increasingly polluted, and the pollution of heavy metals has become one of the most widely polluted and most harmful environmental problems. Due to sewage irrigation and the use of Cd-containing fertilizer materials (sludge, fly ash, etc.), Cd pollution in farmland is becoming more and more serious worldwide. According to incomplete statistics, the area of ​​farmland polluted by Cd in my country has reached 280,000 hm 2 , in the agricultural products produced every year, the Cd content exceeds the standard by 14.6 million tons, which not only seriously endangers the agricultural ec...
