A kind of granulation method of cultivation substrate special for strawberry elevated cultivation

Abstract

The invention discloses a granulation method of a culture substrate for elevated cultivation of strawberries, comprising the following steps: A, stacking river mud outdoors and drying, and putting the river mud in a pulverizer to crush into powder; B, adding 10-20 wt% of pig manure and 10-16 wt% of wood chip in 65-80 wt% of river mud, then regulating the pH value of the mixture to 6.5-7 with lime to obtain organic materials; C, uniformly stirring all organic materials, and pouring the organic materials in a granulator with uniformly stirring and carrying out granulation; D, putting the granulated organic particles in a 800-1000 DEG C oven and baking for 8 min for solidification; and E, in the instant of discharging, putting the sintered organic particles in cooling water for cooling to keep the organic components in the particles. According to the invention, mud obtained from rivers without heavy metal pollution is used, by mixing organic fertilizers required by strawberries with a proper amount of raising agent and sintering, the particles are prepared, and the comprehensive technical requirements of substrate aeration, retention and fertility for elevated cultivation of strawberries are satisfied.

Description

technical field [0001] The invention relates to a special cultivation substrate granulation method for strawberry elevated cultivation, which belongs to the technical field of horticultural crop cultivation. Background technique [0002] Strawberry is an energy-saving and high-efficiency horticultural crop. It is resistant to low temperature, weak light, matures early, and has a relatively concentrated harvest period. It is suitable for solar energy-saving greenhouses and large-scale modern greenhouses to promote production in winter. Compared with other conventional fruits and vegetables, it saves coal and costs. The advantages of low cost and significant economic benefits; at present, there are many technologies for strawberry cultivation substrates, and few technologies for strawberry hydroponic cultivation nutrient solutions, which have high requirements on the environment; soilless cultivation technology is immature, and the application effect is not ideal, especially st...

Problems solved by technology

[0002] Strawberry is an energy-saving and high-efficiency horticultural crop. It is resistant to low temperature, weak light, matures early, and has a relatively concentrated harvest period. It is suitable for solar energy-saving greenhouses and large-scale modern greenhouses to promote production in winter. Compared with other conventional fruits and vegetables, it saves coal and costs. The advantages of low cost and significant economic benefits; at present, there are many technologies for strawberry cultivation substrates, and few technologies for strawberry hydroponic cultivation nutrient solution, which have high requirements on the environment; soilless cultivation technology is immature, and the application effect is not ideal, especially strawberry nutrition is reasonable The technical problem of supply has not been effectively solved; resulting in low strawberry production yield and poor nutrient intake efficiency, which restricts the development of strawberry production
