Planting technology of selenium-rich citrus plants

Abstract

The invention discloses a planting technology of selenium-rich citrus plants. The technology comprises the following steps of: S1, selecting suitable high-quality citrus seeds according to the soil condition of a planting field; S2, excavating planting pits, collecting and improving the excavated soil to obtain backfilling soil, sprinkling water in the planting pits, laying a water retaining agentflatly, laying the backfilling soil flatly, and then sprinkling water; S3, adding the citrus seeds into the planting pits, and then adding the backfilling soil for citrus planting; and S4, spraying selenium-rich fertilizer to soil, sprinkling water regularly, turning the soil every 4-6 months, and meanwhile spraying the selenium-rich fertilizer for two successive days after the soil is turned over; after leaves of the citrus plants emerge, changing the spray mode of the selenium-rich fertilizer to a mode that the selenium-rich fertilizer is sprayed to leaves of the citrus plants until the citrus plants bear fruit, and performing completion of planting of the selenium-rich citrus plants. Through the planting technology, fruit of the planted citrus plants has a high selenium content, a highyield and good taste, and hardening and salinization of the soil do not occur easily.

Description

technical field [0001] The invention relates to the technical field of citrus fruit planting, in particular to a technique for planting selenium-enriched citrus fruit. Background technique [0002] Nowadays, affected by environmental pollution and excessive intake, the content of selenium in soil is generally low, and more than 70% of the soil is in a state of selenium deficiency, of which 30% are seriously deficient in selenium. If the selenium-deficient water and soil Planting and cultivating animals and plants in the state of selenium will make the planted animals and plants also have a state of selenium deficiency, that is to say, areas with selenium deficiency want to take selenium from water and food to supplement the nutrients of various animals, plants and human body. This goal of selenium is difficult to achieve. Organisms themselves cannot synthesize selenium, and some forms of selenium can only be synthesized by plants and then digested and metabolized. The sele...

Problems solved by technology

[0006] When planting citrus fruits, it is often found that the growth of citrus fruits is slow, and chemical fertilizers are often used in the process of planting crucibles, resulting in poor soil performance and insufficient nutrients, and the nutrients in the soil cannot be absorbed by citrus trees, which in turn affects the growth of citrus trees. Make the harvested citrus fruit taste less sweet and less nutritious
