Problems solved by technology

Rice is the main food crop in my country, and the cadmium pollution in rice fields in my country is becoming more and more serious, which poses a serious threat to food security.
At present, there is no very practical and effective treatment method for cadmium pollution in rice fields. The only way to delay the accumulation of cadmium in the soil is to reduce the use of chemical fertilizers and chemical pesticides.

Embodiment 1

[0014] Embodiment 1: a kind of preparation method of paddy field cadmium inhibitor, its preparation method is as follows:

[0015] a. Silage farming: After the corn stalks are green-cut during the corn milk ripening period, the corn stalks are crushed and shredded, and then the corn stalks and EM bacterial agent are mixed evenly according to the weight ratio of 900:1, and packed for Anaerobic fermentation, ferment for 3 days in summer and 5 days in winter to make silage, use this silage to feed livestock and poultry, since antibiotics and antibiotics can be used, there are no antibiotics and antibiotics left in the manure of livestock and poultry;

[0016] b. Straw cushion: Dig a fermentation tank with a depth of 0.9 meters in the livestock and poultry field fence, and alternately layer organic matter and minerals in the fermentation pond until it is flush with the ground in the livestock and poultry field. The livestock and poultry manure discharged from the livestock and pou...

Embodiment 2

[0019] Embodiment 2: a kind of preparation method of paddy field cadmium inhibitor, its preparation method is as follows:

[0020] a. Silage farming: After the corn stalks are green-cut during the corn milk ripening period, the corn stalks are crushed and shredded, and then the corn stalks and EM bacterial agent are mixed evenly according to the weight ratio of 940:1, and packed for Anaerobic fermentation, ferment for 4 days in summer and 6 days in winter to make silage, use this silage to feed livestock and poultry, since antibiotics and antibiotics can not be used, there are no antibiotics and antibiotics left in the manure of livestock and poultry;

[0021] b. Straw cushion: Dig a fermentation tank with a depth of 1 meter in the livestock and poultry field fence, and alternately layer organic matter and minerals in the fermentation pond until it is flush with the ground in the livestock and poultry field. The livestock and poultry manure discharged from the livestock and po...

Embodiment 3

[0024] Embodiment 3: a kind of preparation method of paddy field cadmium inhibitor, its preparation method is as follows:

[0025] a. Silage farming: After the corn stalks are green-cut during the corn milk ripening period, the corn stalks are crushed and shredded, and then the corn stalks and EM bacterial agent are mixed evenly according to the weight ratio of 1000:1, and then packaged. Anaerobic fermentation, ferment for 5 days in summer and 7 days in winter to make silage, use this silage to feed livestock and poultry, since antibiotics and antibiotics can be used, there are no antibiotics and antibiotics in the manure of livestock and poultry;

[0026] b. Straw cushion: Dig a fermentation tank with a depth of 0.96 meters deep in the livestock and poultry field fence, and alternately layer organic matter and minerals in the fermentation pond until it is flush with the ground in the livestock and poultry field fence. The livestock and poultry manure discharged from the lives...

Abstract

The invention discloses a preparation method of a rice field cadmium blocking agent. The preparation method comprises: a, breeding with silage; b, forming a straw cushion layer; and c, preparing the finished product, wherein all the composted materials in a fermentation pool are taken out after a breeding cycle, trace elements are added to the composted materials, an EM microbial agent is added according to a weight ratio of the composted materials to the EM microbial agent of 900:1-1000:1, uniform mixing is performed, anaerobic fermentation is performed, the fermenting is performed for 7-10 days in summer and is performed for 10-15 days in winter, and crushing, screening and packaging are performed after the fermenting is completed to prepare the finished product. According to the presentinvention, the rice field cadmium blocking agent can effectively improve the acid-alkali salt condition of soil and reduce the absorption of heavy metal cadmium in the soil by crops, and is added with the compound containing iron, manganese and other elements so as to effectively increase the contents of organic matters, soil microorganisms and trace elements in soil.

Description

technical field [0001] The invention relates to the technical field of a preparation method of a soil cadmium inhibitor, and more specifically relates to the technical field of a preparation method of a paddy field cadmium inhibitor. Background technique [0002] Cadmium is a heavy metal chemical element. Long-term intake of cadmium-containing foods can cause chronic poisoning of the kidneys, damage renal tubules and glomeruli, and cause proteinuria, aminoaciduria and diabetes. At the same time, because cadmium ions replace calcium in bones Ions, thereby hindering the normal deposition of calcium on the bone, and also hindering the normal solidification and maturation of bone collagen, resulting in chondrosis. Rice is the main food crop in my country, and the cadmium pollution in rice fields in my country is becoming more and more serious, which poses a serious threat to food security. At present, there is no very practical and effective treatment method for cadmium polluti...
