Problems solved by technology

For a long time, the nutrient supply in the soilless cultivation of flowers in my country has been supplied by nutrient solution. The amount of nutrient elements is based on experience or the nutrient solution formula 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 Nutrients are often excessive, which eventually leads to problems such as high investment, low efficiency, and serious waste in the flower industry

Embodiment 1

[0021] Embodiment 1 nutrient solution formula

[0022] Each L of nutrient solution contains: nitrogen 4.04mmol, phosphorus 0.42mmol, potassium 1.16mmol, calcium 1.30mmol, magnesium 0.50mmol, iron 15.30μmol, boron 46.30μmol, manganese 9.50μmol, zinc 0.80μmol, copper 0.30μmol and molybdenum 0.02μmol.

Embodiment 2

[0023] The preparation of embodiment 2 nutrient solution

[0024] Take the preparation of 150L nutrient solution as an example.

[0025] 1. Macronutrients

[0026] 1) First calculate the dosage of each compound and weigh them separately.

[0027] The compound dosages of various macroelements are respectively:

[0028] Calcium nitrate tetrahydrate Ca(NO 3 ) 2 .4H 2 O 46.05g potassium dihydrogen phosphate KH 2 PO 4 8.57g

[0029] Potassium nitrate KNO 3 11.22g, ammonium nitrate NH 4 NO 3 3.24g

[0030] Magnesium Sulfate Heptahydrate MgSO 4 .7H 2 O 18.49g nitric acid HNO 3 (63-64% concentrated nitric acid) 1.5ml

[0031] 2) The calcium salt is placed alone, namely A;

[0032] 3) Mix and put together except calcium salt, namely B.

[0033] 2. Iron salt

[0034] Chelated iron Na 2 The amount of Fe-EDTA used was 0.968 g.

[0035] 3. Trace elements other than iron salts

[0036] Prepare 400 times the mother liquid of trace elements for u...

Embodiment 3

[0045] Application method of embodiment 3 nutrient solution

[0046] 1. With the nutrient solution of embodiment 2, adopt a fixed ratio fertilizer (purchased from Israel Mix Rite company), carry out in conjunction with watering, the concentration of the fixed ratio fertilizer is adjusted to 4%;

[0047] 2. Measure the pH value of the nutrient solution after mixing with a constant ratio fertilizer applicator, using concentrated H 2 SO 4 (98%) or NaOH, adjust the pH value of the nutrient solution to 5.5-6.5;

[0048] 3. Watering, the method is the same as watering, and the lily 'Sorbonne' bulbs are planted in a soilless culture medium with a volume ratio of coconut peat: sand: perlite: vermiculite for 3-4 weeks after application. Water evenly around the root system and avoid pouring on the leaves.

Abstract

The invention provides lilium Sorbonne soilless culture nutrient solution which is prepared by nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, copper, zinc, boron, molybdenum and other nutrient elements according to the appropriate proportion. The nutrient solution is applicable to a specific soilless culture substrate (the volume ratio of coconut peat: sand: perlite: vermiculite is 3: 3: 2: 2). The lilium Sorbonne soilless culture nutrient solution is designed against the specific lily variety of Sorbonne and can meet the demands on nutrition, simultaneously reduce the application amount of the nutrient elements, and fundamentally solve the phenomena that the nutrient solution used in the lily culture adopts the formula of the nutrient solution obtained by experiences or drawing lessens from other crops ever since a long time ago, thereby causing the excess nutrient and causing the great waste during the production. The lilium Sorbonne soilless culture nutrient solution can effectively improve the utilization efficiency of a liquid manure and simultaneously reduce the environmental pollution caused during the culture process of flowers and plants. The lilium Sorbonne soilless culture nutrient solution can further reduce the production cost under the premise of ensuring the quality of cut lily flowers and have obvious social benefits, economic benefits and environmental and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to a nutrient solution for lily 'Sorbonne' soilless cultivation, its preparation method and application. 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 area of ​​cut flower lily was 4716.7 hectares, and the annual sales volume ...
