Nutrient solution for tree

Abstract

The invention discloses a nutrient solution for a tree. The nutrient solution is characterized in that every 1,000 ml of the nutrient solution contains 1,000 to 1,200 mg of potassium nitrate, 2,100 to 2,250 mg of urea, 1,900 to 2,050 mg of ammonium nitrate, 140 to 160 mg of magnesium sulfate, 1,200 to 1,230 mg of ammonium dihydrogen phosphate, 1,360 to 1,380 mg of calcium nitrate, 1,190 to 1,210 mg of monopotassium phosphate, 160 to 180 mg of manganese sulfate, 10 to 12 mg of zinc sulfate, 12 to 14 mg of ferric citrate, 160 to 180 mg of vitamin A, 120 to 140 mg of vitamin C, 80 to 120 mg of vitamin B6, 1 to 2 mg of boric acid, 0.3 to 0.4 mg of sodium molybdate, 0.15 to 0.31 mg of sodium iodide, 0.1 to 0.2 mg of folic acid, 1.5 to 1.7 mg of asparaginate, 1 to 2 mg of fulvic acid, 0.5 to 0.7 mg of indolebutyric acid, 0.8 to 1.2 mg of gibberellins and the balance of water. The nutrient solution for the tree has the beneficial effects that the nutrient solution does not contain a harmful substance, and can supply nutrients for growth to plants subjected to soilless culture.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a tree nutrient solution. Background technique [0002] With the rapid development of the city, the available space is getting smaller and smaller, and the use of soilless cultivation technology to cultivate green plants can effectively save space. This just needs to provide plant nutrient solution for the green plant of soilless cultivation, in order to meet the needs of green plant growth. At present, most of the plant nutrient solutions sold on the market are extracts prepared from chemical fertilizers. The nutrient solution has low purity or contains harmful substances. Long-term use will cause yellowing or death, and the effect is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tree nutrient solution that does not contain harmful substances and can provide nutrients needed for growth of...
