Abstract

The invention discloses a selenium-enriched cultivation method for fruit corn. The selenium-enriched cultivation method comprises the steps of cold plasma pretreatment, selenium-enriched liquid seed soaking, sowing, topdressing, daily management and the like. According to the method, the seeds of the fruit corn are subjected to non-ionizing radiation treatment by adopting cold plasmas, benign stimulation is generated to the seeds, the seed coat permeability can be remarkably improved, the hydrophilicity and the water absorption capacity of the seeds are enhanced, the accumulation of selenium in the seeds is promoted, and the catabolism capacity of seed storage substances is also improved; and therefore, seed germination and seedling growth are remarkably promoted. Meanwhile, in the planting and cultivation process, fertilization is conducted on the periphery of a plant, pollution to field runoff and soil caused by a large amount of residual fertilizer is avoided, and the method is economical and safe. The fruit corn obtained through the cultivation method is high in natural organic selenium content, the stress resistance is remarkably enhanced, and the planting economic benefits ofthe fruit corn are increased. The cultivation method is simple to operate, and has important significance for improving the life of farmer households.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a selenium-enriched cultivation method for fruit corn. Background technique [0002] Fruit corn is a kind of super sweet corn suitable for raw eating. The green stick stage is thin, juicy, crisp and sweet. It can be eaten raw directly. The thin skin will break when bitten, and the fragrant juice overflows the cheeks. It is very sweet and crisp when eaten cooked, like fruit, so it is called "fruit corn". There are many varieties of fruit corn, all of which have very high nutritional value. Fruit corn is rich in vitamins, minerals and free amino acids, etc., which is easy for human body to digest and absorb. It is a new leisure and health-care nutritional food. The total sugar content reaches 33.5%, and the sugar content is as high as 20%, which is about twice that of ordinary fruits and 30% higher than watermelon. [0003] Selenium is one of the essential trace el...
