Abstract

The invention discloses a greenhouse selenium-enriched herba houttuyniae soilless culture method. The greenhouse selenium-enriched herba houttuyniae soilless culture method comprises the following steps that (1) species are selected; (2) a culture bed and a matrix are prepared, and the ratio of the matrix is that mushroom dregs: river sand: sawdust= 3:1:1; (3) base fertilizer is used; (4) a nutrient solution is managed, macroelements of the nutrient solution include tetrahydrated calcium nitrate, potassium nitrate, monopotassium phosphate and epsom salt, and the use amounts are adjusted according to different growth periods; microelements include iron chelate, boracic acid, tetrahydrated manganese sulfate, heptahydrate zinc sulphate, copper sulfate pentahydrate and tetrahydrated ammonium molybdate, and the use amounts are the same in different periods; (5) selenium fertilizer is applied and includes 7.0 g of sodium selenite, 20 g of iron chelate, 20 g of BSFA and 40 kg of water; (6) field management is carried out; (7) harvesting is carried out. After the selenium fertilizer is applied, the selenium content of stems and leaves can reach above 1.5 mg / kg, and the selenium content of roots and stems can reach 0.3-1.0 mg / kg.

Description
