Selenium-enriched watermelon culture medium and preparation method thereof

Abstract

The invention discloses a selenium-enriched watermelon culture medium. The selenium-enriched watermelon culture medium is prepared from 40-50 parts of earthworm cast, 10-15 parts of vermiculite, 8-10 parts of perlite, 10-15 parts of a molasses fermentation solution, 3-5 parts of garlic husks, 3-5 parts of tangerine pith, 3-5 parts of fermentation strains, 20-30 parts of soft sediments with the water content being 90%, 15-20 parts of milkvetch roots, 3-5 parts of sea-buckthorn, 3-5 parts of cactus, 3-5 parts of aloes, 3-5 parts of alfalfa, 3-5 parts of konjac, 3-5 parts of water hyacinth, 1-2 parts of fosamine ammonium and 10-20 parts of inorganic fertilizer. The fermentation strains include saccharomycetes, lactic acid bacteria, actinomycetes and bacillus. The invention further discloses a preparation method of the selenium-enriched watermelon culture medium. The selenium-enriched watermelon culture medium is comprehensive in nutrient and coordinated in ratio balance, watermelons can be supplied with sufficient and coordinated nutrients in the overall watermelon growth period, watermelon growth is effectively promoted, and efficient production increase can be achieved while the good quality of watermelons is ensured.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation. More specifically, the invention relates to a selenium-enriched watermelon cultivation substrate and a preparation method thereof. Background technique [0002] Watermelon is a kind of fruit that consumers like very much. It is rich in nutrition, good in flavor and hygienic quality. With the improvement of people's living standards and the enhancement of food safety awareness, it has become more and more popular among consumers. However, traditional watermelon planting methods limit the growth of watermelons. Many planting methods have a low germination rate of watermelons, often appear weak seedlings, and the yield of watermelons is not high. The selenium content of watermelons produced in ordinary areas is generally lower than 1 μg / kg, and people’s selenium intake from them is very limited, so fortifying them with selenium nutrition is a better way to enhance the level of sel...

Problems solved by technology

[0004] At present, the most commonly used cultivation substrates are mainly vermiculite and perlite, but they are prone to compaction, poor permeability, poor nutrient balance, and small buffer performance. Meet the needs of watermelon germination, emergence and growth
