Soilless culture substrate capable of improving yield of cucumber

Abstract

The invention discloses a soilless culture substrate capable of improving the yield of cucumber. The soilless culture substrate comprises the following raw materials in parts by weight: 30 to 40 partsof wormcast, 30 to 40 parts of sunflower seed meal, 20 and 26 parts of protein ooze, 18 to 24 parts of pond silt, 10 to 18 parts of beer distillers' grains, 0.4 to 0.8 part of an EM microbial agent,25 to 30 parts of an adsorption filler, 20 to 30 parts of kainite, 4 to 8 parts of rice straw, 6 to 12 parts of coconut shell charcoal, 2 to 4 parts of wood flour, 2 to 4 parts of pine needle powder and 10 to 15 parts of a binder, wherein the binder comprises the following components in parts by weight: 4 to 10 parts of a nutrient-preserving agent, 2 to 4 parts of carrageenan and 2 to 4 parts of cyclodextrin; and the nutrient-preserving agent is prepared through the following process: mixing carbon fiber and a nitric acid solution, carrying out heating under stirring, carrying out cooling andfiltering, washing a filter cake until a pH value of the filter cake is 6.5 to 6.9, carrying out drying, adding a silane coupling agent, bentonite and ammonium bicarbonate, carrying out mixing and grinding, then adding paraffin, adjusting a temperature, carrying out uniform mixing under stirring, and carrying out freeze-drying so as to obtain the nutrient-preserving agent.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a soilless cultivation substrate for improving cucumber yield. Background technique [0002] Cucumber is one of the vegetables commonly grown all over the world. It has a long history of cultivation and is cultivated under different ecological environment conditions all over the world. In the process of soilless cultivation of cucumber, the fertilization method in the production of fresh cucumber is often followed, blindly Too much water and too much fertilizer not only wastes precious water resources, but also has no obvious effect on increasing the yield of cucumbers, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a soilless cultivation substrate for increasing the yield of cucumbers, which has the effects of excellent water and ...
