Soilless culture nutrient solution for spiraea bumalda seedlings and preparation method of soilless culture nutrient solution

Abstract

The invention provides a soilless culture nutrient solution for spiraea bumalda seedlings and a preparation method of the soilless culture nutrient solution and relates to the technical field of plant cultivation fertilizers. The culture medium disclosed by the invention comprises the following raw materials: borax, probiotics, growth hormones, amino acids, calcium gluconate, ammonium molybdate, manganese chloride, monopotassium phosphate, copper sulfate, magnesium sulfate, sodium iodide, sodium ethylene diamine tetracetate, urea, trace elements and water. The soilless culture nutrient solution for spiraea bumalda seedlings disclosed by the invention is reasonable in components and rich in nutrition, has various nutrient elements and trace elements needed by growth and development of the spiraea bumalda seedlings, is capable of enabling plants to grow strongly and rapidly accumulating dry matters, and is high in outside stress resistance. The period of emergence can be effectively shortened, the emergence rate and seedling raising quality of the spiraea bumalda seedlings are improved, a root rot phenomenon is avoided, and the survival rate is high.

Description

technical field [0001] The invention relates to the technical field of plant cultivation fertilizers, in particular to a nutrient solution for soilless cultivation of Spiraea spiraea seedlings and a preparation method thereof. Background technique [0002] Spiraea aurea is a small deciduous shrub with a plant height of 60-110cm and a crown width of 90-120cm. The old branches are dark brown and the new branches are yellowish brown. The branches are in the shape of broken lines, not straight and soft. The winter buds are small, with scales, alternate single leaves, sharply serrated edges, and pinnate veins. Leaf length 0.8-3.0cm, width 0.5-1.6cm, petiole 0.2-0.4cm. Short petiole, no stipules, bisexual flowers, corymb, calyx bell-shaped, 5 sepals, 5 petals, round and longer than sepals, stamens longer than petals, inserted between disk and sepals, carpels 5, separated pregnancy. Pods 5, dehiscated along the ventral suture, with several small seeds inside, the seeds are round...

Problems solved by technology

[0003] Spiraea spiraea mostly adopts asexual cutting seedlings to propagate seedlings, which is an effective way to maintain the purity of spirea species, prevent degradation and expand seedling breeding, but spirea spiraea In the stage of chrysanthemum seedling cultivation, especially in the later stage of seedling cultivation, the nutrients are easy to fail to keep up, and the seedlings of Spiraea spiraea at this time are relatively fragile, which will reduce the survival rate of Spiraea spiraea transplanting.

[0004] At present, most of the nutrient solutions on the market are not specially used for certain plants. It is difficult to apply to all hydroponic flowers. Different plants need different nutrient solutions.

And the existing hydroponic nutrient solution is easy to cause phenomena such as rotten roots to appear in the plant under the sudden change of temperature, and the hydroponic survival rate is low. It is particularly important in the cultivation field of Spiraea spiraea
