Problems solved by technology

[0003] The above formula was invented by Japanese agriculturalist Kenya Yamazaki in the late 1970s. It has a history of more than 30 years. During this period, the breeding technology has improved and the hydroponic technology has developed rapidly. Nature likes cold, in warm and humid climate in spring, lettuce is easy to cause necrosis and rot of leaf core due to local heat dissipation, resulting in poor growth

Embodiment

[0012] Embodiment: a kind of special formula for hydroponic lettuce in spring:

[0013] (1) Take by weighing 235 milligrams of calcium nitrate tetrahydrate and 380 milligrams of potassium nitrate, add one by one, stir to make it fully dissolved in the beaker (containing 500 milliliters of water);

[0014] (2) Weigh 300 mg of potassium dihydrogen phosphate, pour the drug into a beaker while stirring fully, add 100 ml of water, weigh 245 mg of magnesium sulfate heptahydrate, pour the drug into a beaker while fully stirring, and add 100 ml of water , Weigh 50 mg of ammonium dihydrogen phosphate, pour the drug into a beaker while fully stirring, and add 100 ml of water;

[0015] (3) Take by weighing 2.86 mg of boric acid, 2.13 mg of manganese sulfate, 0.22 mg of zinc sulfate, 0.08 mg of copper sulfate, 0.02 mg of ammonium molybdate, and then dissolve them one by one in a beaker and add 100 milligrams of water;

[0016] (4) Take 20 mg of EDTA-2Na, add 1 liter of water to the ename...

Abstract

The invention discloses a special formula for water plantation of lettuce in spring. The formula contains 0.05mg / L of salicylic acid and 1.2mg / L of chelated iron. Salicylic acid added in the formula can promote the water saturation of lettuce leaf cells, prevent water shortage caused by cell membrane damage, maintain the water balance between inner and outer leaves, improve the stress resistance of the lettuce to warm and humid environment and avoid the necrotic decay of the heart of the lettuce in the whole growth stage in spring by maintaining the activity lasting effect of salicylic acid through chelating iron.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a hydroponic formula. Background technique [0002] In the prior art, most of the formulas for hydroponic artemisia are general-purpose formulas for all seasons, which do not address the differences in the nutritional requirements of lettuce in different seasons, resulting in stagnant production efficiency of lettuce. The preparation process of existing formula is, take by weighing 236 milligrams of calcium nitrate tetrahydrate of liquid A medicine, 404 milligrams of potassium nitrate, add one by one, stir to make it fully dissolve in the beaker (containing 600 milliliters of water); Then weigh the medicine of liquid B Ammonium dihydrogen phosphate 57 mg, pour the drug into a beaker while stirring fully, add 100 ml of water, weigh 123 mg of magnesium sulfate heptahydrate, pour the drug into a beaker while fully stirring, and add 100 ml of water; then weigh C liquid drug ferrous sul...
