Problems solved by technology

For a long time, the nutrient supply in the soilless cultivation of flowers in our country has been supplied by nutrient solution. The amount of nutrient elements is based on experience or the nutrient solution of other varieties of crops. There is a lack of in-depth research on the nutrient requirements and nutrient accumulation rules of specific varieties of flowers, resulting in nutrient deficiency. Often excessive, eventually leading to problems such as high investment, low efficiency, and serious waste in the flower industry

Abstract

The invention provides a soilless culture nutrient solution for lily as well as a preparation method and application thereof. The nutrient solution consists of macroelements, trace elements and water, wherein the macroelements in every liter of the nutrient solution comprise 6.15-6.25mmol of nitrogen, 0.25-0.35mmol of phosphorus, 1.80-1.90mmol of potassium, 1.20-1.40mmol of calcium and 0.40-0.60mmol of magnesium; and the trace elements in every liter of the nutrient solution comprise 15.00-16.00 mu mol of iron, 45.00-50.00mu mol of boron, 9.00-10.00 mu mol of manganese, 0.75-0.85 mu mol of zinc, 0.25-0.35 mu mol of copper and 0.10-0.30 mu mol of molybdenum. The soilless culture nutrient solution is especially suitable for culturing lily by utilizing a special soilless culture substrate, can meet the nutrition requirement of lily and reduce the applying amount of the nutriment elements, thereby fundamentally solving the phenomenon of great waste in production because of the nutrition excess caused by the fact that culture nutrient solution is not specially for lily for a long term and is just prepared experientially or on the basis of the preparation of nutriment solutions for other crops.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, more specifically to a nutrient solution for soilless cultivation of lilies, and also relates to a preparation method and application of the nutrient solution for soilless cultivation of lilies. Background technique [0002] Lilium spp., also known as Lily Garlic, Moro, Zhongfenghua, Zhongting, etc., is an autumn bulbous flower of the Liliaceae (Liliaceae) Lilium (Lilium). Ground cultivation can be used for annual production and flowers for four seasons. [0003] Lily is favored by people from all over the world for its elegant flower posture and rich colors, and has become a leader in the international flower market. It is also loved by the Chinese people for its beautiful meaning of "a hundred years of harmony", and it has developed rapidly in my country's flower industry in recent years. By 2007, the national cut flower planting area reached 33777.5 hectares, of which the planting...
