Embodiment 1

[0010] Embodiment 1: a kind of lettuce soilless cultivation nutrient formula, by weight, its composition is

[0011] Nutrition: 13 parts; earthworm: 10 parts; ginkgo: 3 parts; leucine: 4 parts; serine protease: 4 parts; glutamine: 4 parts; realgar: 1 part; rhinoceros horn: 1 part; serine: 1 part ; Water: 100 parts.

Embodiment 3

[0013] Nutrition: 16 parts; earthworm: 14 parts; ginkgo: 30 parts; leucine: 6 parts; serine protease: 6 parts; glutamine: 6 parts; realgar: 3 parts; rhinoceros horn: 3 parts; serine: 3 parts ; Water: 800 parts.

[0014] Through a large number of experiments, this application adjusts the composition and ratio of the nutrient solution, and adds an appropriate amount of trace elements such as glutamine, realgar, rhinoceros horn, and serine to reduce the symptoms of deficiencies, and at the same time allow plants to absorb them simultaneously. The nutrient fertilizer that can still be absorbed by the roots has greatly enhanced penetration and diffusivity, making it easy for the roots of the crops to absorb it, and quickly penetrate into the roots of the crops, and the root hairs of the roots are many and white. The leaves are dark green, the seedlings are tall, the stems are thick and strong, the main roots are many and long, and there are many fibrous roots; the resistance is str...

Abstract

The invention discloses a lettuce soilless culture nutrition formulation. The lettuce soilless culture nutrient solution is prepared from, by weight, 13-16 parts of fructus rosae multiflorae, 10-14 parts of earthworms, 3-30 parts of gingkoes, 4-6 parts of leucine, 4-6 parts of serine protease, 4-6 parts of glutamine, 1-3 parts of realgar, 1-3 parts of rhinoceros horns, 1-3 parts of serine and the balance water. The materials are weighed according to the ratio and mixed to be uniform, and then the nutrient solution is obtained. By means of the nutrient solution, the seepage force and diffusivity of the nutrient solution are greatly enhanced during seedling culture, accordingly, the seeding stage is greatly shortened, the emergence rate is increased, emergence quality is improved, and meanwhile cost is reduced. The nutrient solution is more suitable for high-altitude low-temperature seedling culture.

Description

technical field [0001] The invention relates to a nutritional formula for soilless cultivation, in particular to a nutritional formula for soilless cultivation of lettuce. Background technique [0002] Lettuce roots stick straight up. The stem is erect, solitary, the upper part is branched in a panicle, and all the stems and branches are white. Basal leaves and lower stems and leaves are large, undivided, oblanceolate, elliptic or elliptic oblanceolate, 6-15 cm long, 1.5-6.5 cm wide, apex acute, short acuminate or rounded, Sessile, heart-shaped or arrow-shaped semi-ambulatory stems at the base, wavy or finely serrated edges, tapering upwards, the same shape as the basal leaves and lower stems and leaves, or lanceolate, the leaves and panicles at the lower part of the panicle branches are divided The leaves on the branches are very small, egg-shaped, heart-shaped, sessile, with heart-shaped or arrow-shaped amphibians at the base, entire margins, and all leaves are glabrous ...
