Selenium-rich tea-oil tree planting method

Abstract

The invention discloses a selenium-rich tea-oil tree planting method. The selenium-rich tea-oil tree planting method comprises the steps that land improvement is performed, wherein sandy land with the slope smaller than or equal to 25 degrees is selected as land to be used, uniform turnover and ploughing are performed, then a land improver is applied based on 50-80 kg / mu, and natural keeping is performed for 2-3 days; the land improver is applied again based on 30-60 kg / mu, uniform turnover and ploughing are performed, and natural keeping is performed for 10-20 days; then, selenium-rich farmyard manure is applied based on 1500-2200 kg / mu, the land is raked to be fine, and improved land is obtained, wherein the land improver is prepared from gypsum, cinnamon soil, phosphogypsum, ferrous sulfate, sulfur powder, weathered coal, water, zinc sulfate, chitin, carboxymethyl chitosan, heparin, sodium alginate, chitosan, sulfate, phosphate and acetic acid. The selenium-rich tea-oil tree planting method has the advantages that planting land can be improved to provide acid soil conditions suitable for growth of tea-oil trees, meanwhile the selenium-rich farmyard manure is applied to soil for improvement of a soil nutrition structure of the planting land, so that the tea-oil trees grow rapidly, and nutritional ingredients are comprehensive and contain a selenium element required by a human body.

Description

technical field [0001] The invention relates to the technical field of planting woody oil plants, in particular to a planting method of selenium-enriched camellia oleifera. Background technique [0002] Selenium-enriched oil is a high-tech product produced by scientific methods and technology. It achieves the purpose of enriching selenium by naturally adding selenium in the production process. It is a real pure natural green edible oil. In recent years, with the improvement of people's living standards, selenium-enriched camellia oil has become more and more popular, and the market is in short supply. Therefore, the development of selenium-enriched camellia oil is of great significance to human health. However, Camellia oleifera is suitable for growing in acidic soils with a pH of 5-6.5. In acidic soils, basic ferric selenite, which is insoluble in selenium, is fixed and cannot be easily absorbed and utilized by plant roots. Moreover, there are very few selenium-enriched ar...

Problems solved by technology

However, Camellia oleifera is suitable for growing in acidic soils with a pH of 5-6.5. In acidic soils, basic ferric selenite, which is insoluble in selenium, is fixed and cannot be easily absorbed and utilized by plant roots.

Moreover, there are very few selenium-enriched areas in my country at present, so the selenium content of camellia oleifera trees planted by common planting methods is very small, which limits and develops the production of selenium-enriched camellia oleifera in my country.

[0003] The patent application number is 201210316373.0, which discloses a selenium-rich planting method of Camellia oleifera, including forest land selection, scientific land preparation, reasonable density, scientific planting, intensive cultivation, implementation of selenium fertilizer, scientific fertilization, pest control and fruit harvesting; This invention can make Camellia oleifera trees grow selenium-containing Camellia oleifera trees in selenium-deficient areas, but the selenium content is not high, so it is not suitable for the planting of neutral or alkaline selenium-enriched camellia oleifera trees
