Planting method of selenium-enriched anoectochilus roxburghii hayata

Abstract

The invention discloses a planting method of selenium-enriched anoectochilus roxburghii hayata. The method includes the steps that straw, saw dust, tea cakes and sheep dung in selenium-enriched areas are collected, separately smashed and then mixed, water is sprayed in an evenly mixing process, and obtained mixture is stacked into a stack; 10-15 days after stack retting, the stack is turned over for the first time, and moisture is supplemented; moisture is preserved, and stacking is conducted again; then, every five days, the stack is turned over, moisture is supplemented and the stacking is conducted again; fermentation is conducted till substrate turns to black brown, when the temperature falls to a near ambient temperature, humus soil (with natural orchid mycorrhizal fungi) collected in a growth place of wild anoectochilus roxburghii hayata is added and evenly stirred in the substrate, and planting substrate is obtained; greenhouse cultivation or under-forest imitative wild planting is conducted on tissue culturing seedlings of the anoectochilus roxburghii hayata by the adoption of draught-fan water-curtain equipment; clear water is sprayed according to the humidity of the substrate, and ventilation and light penetration are ensured; biological prevention and control on plant diseases and insect pests are conducted; harvest is carried out. The obtained anoectochilus roxburghii hayata has relatively good agronomic trait indexes, the biological yield is improved, and the content of flavone, the content of active polysaccharide and the content of selenium are significantly increased. The materials of the substrate turn waste into wealth, the pollution is reduced, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a planting method of selenium-enriched clematis. Background technique [0002] The incidence of more than 40 kinds of diseases in the human body is directly related to the lack of selenium intake in the human body. Selenium is an essential trace element for humans and animals. The Chinese Nutrition Society recommends a daily selenium intake of 50-250 micrograms per day. However, scientists have found that the content of selenium in the earth's crust is only 0.05 micrograms per gram. Two-thirds of China's population is facing the threat of insufficient selenium intake, and the world's population facing the "hidden hunger" of selenium is as high as 1.5 billion. The selenium content in the soil in most areas is lacking and the distribution is uneven. There are also some areas that are rich in selenium, such as Enshi in Hubei, Kaiyang in Guizhou, Ziyang in Shaanxi, Taoyuan in Hu...

Problems solved by technology

However, my country's peat soil resources are relatively poor, and the quality of peat soil is relatively poor. Most of them rely on imported peat soil, and the production cost is high.

In addition, peat soil resources are accumulated over a long period of time. Once the resources are excavated, it is difficult to restore them in a short period of time, which is also a plunder and damage to the ecological environment.
