Activating agent for activating soil selenium and cultivation method of selenium-rich chives

Abstract

The invention discloses an activating agent for activating soil selenium, which is mainly prepared from the following raw materials: potassium fulvate, quicklime powder and EM bacterial powder. According to the activating agent for activating the soil selenium, the activating agent is sprinkled on the surface of the soil during soil preparation, and then the soil on the surface of the soil and theactivating agent are fully mixed, and thus the selenium in the soil is activated and is easy to be absorbed by plants, so that the selenium content of the plants is increased. According to the activating agent, not only can the selenium element in the soil be effectively utilized in the selenium-containing soil, but also no additional exogenous selenium element needs to be added, so that the agent is safe and environment-friendly. According to the cultivation method of the selenium-rich chives, the selenium content in the chives can be mentioned after the chives are planted by applying the selenium-activated activating agent on the soil surface, so that the selenium-rich content of the chives can be effectively improved, and the yield, quality and cost of the chives are moderate. Plantingper mu only increases the cost of 100 yuan / stubble, and compared with the traditional chive germplasm, the experiment shows that the yield per mu can be increased by about 10%, and the quality of theproduced chive is better, and thus the economic benefits are improved.

Description

technical field [0001] The invention relates to the field of selenium-enriched vegetable cultivation, in particular to an activator for soil selenium activation and a cultivation method for selenium-enriched shallots. Background technique [0002] Chives, also known as chives and shallots, are perennial clustered herbaceous plants of the Liliaceae Allium genus. They are fed with young leaves and pseudostems. They are pungent and warm in nature and have a special spicy smell. Certain medicinal value. Chives are cold-resistant, fertilizer-resistant, adaptable, easy to plant, and require less investment. They are cultivated all over my country and grow year-round. They can prevent diseases and repel insects when used in intercropping, and can improve the physical and chemical properties of soil when used in crop rotation. Chives are one of the main varieties of my country's "South Vegetables Transported North" and export processing vegetables, with high output and economic ben...
