Dracaena sanderiana soilless culture nutrient formula and application thereof

Abstract

The invention discloses a dracaena sanderiana soilless culture nutrient formula comprising the components in parts by weight: 13-18 parts of diisopropanolamine, 10-12.5 parts of ammonium ferric sulfate, 2-20 parts of salicylic acid, 4-5 parts of tryptophan, 4-5 parts of threonine, 0.4-0.6 part of palladium nitrate, 0.1-0.3 part of barium hydroxide, 0.1-0.3 part of iodine pentoxide, 0.08-0.2 part of calcium gluconate, and the balance water; the nutrient formula is obtained by weighing the components according to the proportion and mixing evenly; with the use of the nutrient solution, the osmotic force and diffusivity of the nutrient solution are increased greatly during seedling culture, and thus the seedling emergence period is greatly shortened, the seedling emergence rate and the quality of emergence seedlings are improved, and besides, the cost is reduced; and 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 lucky bamboo soilless cultivation. Background technique [0002] Lucky Bamboo belongs to the genus Dracaena in the family Liliaceae. It is a perennial evergreen herb. Bonsai Lucky Bamboo Lucky Bamboo, also known as (Wannian Bamboo), mainly grows in the southwest of my country, also known as Water Bamboo, which is a perennial evergreen small tree foliage plant. The height of the plant is more than 1m, the plant is slender, with branches in the upper part of the upright. If it is used as a commodity or a work of art, the cultivation height should be 80-100 cm. Rhizome transverse, nodular. Leaves alternate or nearly opposite, papery, long lanceolate, with 3 to 7 main veins, short stalk, dark green. Umbels have 3-10 flowers born in leaf axils or opposite to upper leaves, with 6 perianth, corolla bell-shaped, purple. Berries subglobose, ...

AI Technical Summary

Problems solved by technology

For floating seedlings, the most critical technologies include floating seedling substrates, soilless cultivation nutritional formula, etc. Among them, the soilless cultivation nutritional formula is particularly important for the improvement of seedling cultivation period, emergence rate and emergence quality, but the current soilless cultivation nutritional formula , not suitable for floating seedlings of Lucky Bamboo
