Culture substrate for strawberry

Abstract

The invention provides a culture substrate for strawberry. The culture substrate comprises the following components in parts by weight: 25 to 50 parts of river sludge, 15 to 25 parts of straw powder, 1 to 3 parts of urea, 8 to 10 parts of yeast residue, 1 to 2 parts of mineral ash powder, 5 to 10 parts of a porous material and 3 to 5 parts of a compound fertilizer. The culture substrate for the strawberry is prepared by mixing the river sludge, the urea, the yeast residue, the mineral ash powder, the porous material and fermented straw. The culture substrate for the strawberry provided by the invention has the following advantages: the straw contains rich trace elements after fermented and decomposed, and has high contents of organic matters and nutrients, so the nutrients are provided for the growth of the strawberry; the yeast residue contains biological active matters like amino acid and saccharides, and facilitates to improving substrate structure; and the decomposition of the mineral ash powder increases the content of trace elements in the substrate, and facilitates to promoting photosynthesis of the strawberry, so the quality of the strawberry is improved. The culture substrate for the strawberry provided by the invention has abundant nutrients, rich trace elements and strong water-retention and nutrient-preserving capabilities, and can be extensively applied in cultivation of the strawberry.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a strawberry cultivation substrate. Background technique [0002] Strawberry is a fruit with high nutritional value, which is 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., can be eaten raw and can also be made into jam, which is deeply loved by the people, and the demand is increasing, and the cultivation of strawberries is also more and more extensive. Strawberry cultivation medium plays a vital role in the strawberry cultivation process. At present, strawberry cultivation medium generally uses peat and rock wool as the main raw materials. Since peat is a non-renewable resource, the demand for it is increasing year by year, resulting in the cost price of the substrate. Higher, but rock wool is non-degradable, long-term use will cause s...

Strawberry cultivation medium plays a vital role in the strawberry cultivation process. At present, strawberry cultivation medium generally uses peat and rock wool as the main raw materials. Since peat is a non-renewable resource, the demand for it is increasing year by year, resulting in the cost price of the substrate. Higher, but rock wool is non-degradable, long-term use will cause serious environmental pollution, and some use farmyard manure and sawdust as the main material as the substrate. This kind of substrate will harden after long-term use, resulting in permeability of the substrate and rotten strawberries. Insufficient root or nutrient absorption
