Special soilless culture substrate for strawberries

Abstract

The invention relates to a strawberry culture substrate, in particular to a special soilless culture substrate for strawberries. The substrate is formed by mixing 15%-20% of green alga, 10%-12% of spirogyra, 15%-20% of rotten wood, 30%-40% of hyperphosphate slag, 10%-15% of beer grain, 5%-10% of apple pomace, 0.1%-0.3% of zinc ash, 0.2%-0.4% of manganese ash, 0.1%-0.3% of silica ash and 8%-10% of fresh banana skin. According to the special soilless culture substrate for the strawberries, waste is selected as substrate raw materials, natural waste resources are fully utilized, so environment pollution is reduced; the substrate has high content of microelements like zinc and manganese, so the requirements of the strawberries for microorganism elements can be satisfied; in the planting process, the phenomena that nutrients are luxuriant in the early period of strawberry planting process or nutrients are inadequate in the later period of strawberry planting process can be avoided through ceaselessly slow release of nutritional ingredients of the substrate, the requirements of the strawberries for the nutrients in a whole growing period can be met, external fertilization is not needed in the planting process, just the daily water requirement needs to be satisfied, water can flow quickly through the substrate, and germination of bacteria sources of powdery mildew, gray mold and anthracnose is avoided; accordingly, growth of roots of the strawberries is promoted, protection layers are formed on surfaces of the roots, and the disease-resistance capacity of seedlings is improved.

Description

technical field [0001] The invention relates to a strawberry cultivation substrate, in particular to a strawberry soilless cultivation substrate. 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 calcium, magnesium, phosphorus, iron, etc. These nutrients are very important for growth and development. Good boost. It can be eaten raw or made into jam for long-term preservation. 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.

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
