Fruit and vegetable nutrient solution

Abstract

The invention discloses a fruit and vegetable nutrient solution. The fruit and vegetable nutrient solution comprises a solution A and a solution B, wherein the solution A mainly consists of the following components: calcium nitrate, potassium nitrate, ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) ferric-sodium complex (EDDHA-Fe), ethylene diamine tetraacetic acid disodium ferric salt (EDTA-Fe); and the solution B mainly consists of the following components: magnesium sulfate heptahydrate, potassium sulfate, potassium dihydrogen phosphate, manganese sulfate tetrahydrate, boric acid, zincsulfate heptahydrate, copper sulphate pentahydrate, and ammonium molybdate. The fruit and vegetable nutrient solution is rich in nutrients, does not contain harmful substances, promotes crop growth,is suitable for hydroponic and substrate culture, and is suitable for large-scale popularization; and the culture solution and matrix of the nutrient solution are easy to renew, and pathogenic bacteria are also easy to remove, so that disease and pest control and soil disinfection are almost not needed, and continuous cropping obstacle can be avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a fruit and vegetable nutrient solution. Background technique [0002] At present, fruit and vegetable crops are generally cultivated by soil cultivation, but soil cultivation is prone to continuous cropping obstacles, because frequent continuous cropping will make the soil unsuitable for cultivation due to insect pests, continuous accumulation of salt in the soil, soil acidification, compaction, etc. will cause Soil fertility declines and deteriorates. Moreover, environmental pollution, especially soil pollution, brought about by industrial development has caused great difficulties in high-yield, high-quality, and pollution-free production of crops. Soilless cultivation refers to using nutrient solution or The method of cultivating crops with solid substrate and nutrient solution has changed the planting habit of agricultural production that has relied on soil sinc...

Problems solved by technology

[0002] At present, fruit and vegetable crops are generally cultivated by soil cultivation, but soil cultivation is prone to continuous cropping obstacles, because frequent continuous cropping will make the soil unsuitable for cultivation due to insect pests, continuous accumulation of salt in the soil, soil acidification, compaction, etc. will cause Soil fertility declines and deteriorates. Moreover, environmental pollution, especially soil pollution, brought about by industrial development has caused great difficulties in high-yield, high-quality, and pollution-free production of crops. Soilless cultivation refers to the use of nutrient solution or soil without soil. The method of cultivating crops with solid substrate and nutrient solution has changed the planting habit of agricultural production that has relied on soil since ancient times, and pushed agricultural production to a new stage of industrial production and commercial production. At present, most of the nutrient solutions sold on the market are Extracts prepared from chemical fertilizers have low nutrient purity or contain harmful substances. Long-term use will cause plants to turn yellow or die, and the effect is not good.
