Preparation method of special soilless culture medium for strawberries

Abstract

The invention relates to a strawberry culture medium, in particular to a special soilless culture medium for strawberries. According to the special soilless culture, an upper-layer medium is prepared by mixing green algae, spirogyra, zinc ash, manganese ash and silica fume, a middle-layer medium is prepared by mixing rotten wood, brewer's grains and apple pomace, and high-phosphate slag powder is taken as a bottom-layer medium. Waste is taken as a medium raw material, waste natural resources are sufficiently utilized, environmental pollution is reduced, the special soilless culture medium contains higher trace elements such as zinc, manganese and the like and meets the demands of strawberries for microorganism elements, the medium continuously and slowly releases nutritional ingredients in the planting process, accordingly, the phenomena of overnutrition at the earlier stage of strawberry planting and nutrition deficiency in the later planting period of the strawberries cannot be caused, the nutrition demand of the strawberries in the whole growth period is met, outside fertilization is not required in the culture process, all that is required is to meet the daily water demand, the medium can rapidly dredge water, microbial source germination of powdery mildew, gray mold and anthracnose is avoided, root growth of the strawberries can be promoted, a protective layer is formed on the surfaces of root systems, and the disease-resistant capability of seedlings is improved.

Description

Technical field [0001] The invention relates to a strawberry cultivation substrate, in particular to a special substrate for strawberry soilless cultivation. Background technique [0002] Strawberries are rich in amino acids, fructose, sucrose, glucose, citric acid, malic acid, pectin, carotene, vitamin B1, vitamin B2, niacin, and minerals such as calcium, magnesium, phosphorus, iron, etc. These nutrients are very important for growth and development. Good promotion. It can be eaten raw and can be made into jam for long-term preservation. Strawberry has high nutritional value, rich in vitamin C, and has the effect of helping digestion. At the same time, strawberry can also strengthen the gums, refresh the breath, moisturize the throat, and have anti-cancer effects. At present, due to the shortage of land resources in the country, soilless cultivation technology Gradually emerging, soilless cultivation mainly relies on the cultivation substrate to provide nutrition for strawberr...

Problems solved by technology

Strawberries have high nutritional value and are rich in vitamin C, which can help digestion. At the same time, strawberries can also strengthen the gums, freshen the breath, moisten the throat, and have anti-cancer effects. Due to the shortage of land resources in the country, soilless cultivation techniques Gradually rising, soilless cultivation mainly relies on the cultivation substrate to provide nutrients for strawberries. Soilless cultivation is generally divided into inorganic energy-consuming soilless cultivation and organic ecological soilless cultivation. Inorganic energy-consuming soilless cultivation uses nutrient solution to irrigate crops. , this method is not only costly, but also troublesome to manage, and the nitrate content of the grown vegetables and fruits is high, causing environmental pollution and high energy consumption; organic ecological soilless cultivation uses solid organic medium to cultivate fruits and vegetables. Low energy consumption and convenient management. The medium plays a vital role in the cultivation process. At present, peat is generally used as the main raw material for the medium. Since peat is a non-renewable resource and its demand is increasing year by year, the cost of the substrate is relatively high. High, if the substrate components are not properly configured, cultivated crops are prone to malnutrition, and the current soilless cultivation substrate generally has the problem of poor buffering capacity, which leads to unsmooth water and fertilizer supply and discharge in the later period. In the long run, cultivated crops are prone to malnutrition Root rot or inadequate nutrient absorption
