Abstract

The invention relates to a nutrient solution for soilless culture, and a preparation method of the nutrient solution. The nutrient solution for the soilless culture is prepared from fertilizer raw materials and water, and is characterized by containing a buffer solution. The nutrient solution for the soilless culture has an improved buffer ability, can prevent plant roots from being rotten, and improves the yield and quality.

Description

technical field [0001] The invention relates to a soilless culture nutrient solution and a preparation method thereof. Background technique [0002] Soilless cultivation refers to the method of cultivating plants with nutrient solution and other equipment without soil. There are solid matrix type and liquid matrix type. The former includes sand-based culture, gravel-based culture, shallow stone culture, rock wool culture, perlite culture, sawdust culture, foam plastic culture, etc. Compared with soil cultivation, it has high yield, good quality, water saving, fertilizer saving and labor saving. [0003] Soilless cultivation can avoid the loss and leakage of soil irrigation water, nutrients and the absorption and fixation of soil microorganisms, which can be fully absorbed and utilized by crops and improve utilization efficiency. The water consumption of soilless cultivation is only about 1 / 4 to 1 / 10 of that of soil cultivation. Saving water resources is of great significan...
