Problems solved by technology
Soilless cultivation technology is one of the better solutions to ensure modern agriculture. However, starting from the current situation in our country, the northern region represented by Beijing has a high concentration of calcium and magnesium ions in the water quality, and the EC value is as high as about 1.0ms / cm. It is not suitable for the development of hydroponic technology, which requires local materials and the development of soilless cultivation technology according to local conditions

Embodiment Construction
[0016] The technical solution of the present invention will be described in detail below.
[0017] The invention provides a kind of method for soilless cultivation shallot, it is characterized in that, comprises the steps:
[0018] 1) Select good quality onion seeds, wash them with clean water first, and then soak them in rice washing water at 30 degrees Celsius for 10-12 hours; soaking green onion seeds in rice washing water at 30 degrees Celsius will have a very good effect.
[0019] 2) Select a plastic cultivation box with a length of 60cm, a height of 45cm, and a width of 25cm for cultivation. First, spread a layer of substrate, and then plant the soaked onion seeds into the substrate cultivation tank at intervals of 3cm between plants and 8cm between rows, and spray with warm water at 20 degrees Celsius. , cover the cultivation box cover, move to the cultivation room, and cover the top of the box cover with a damp sponge, and control the temperature at 28-30 degrees Celsi...

The invention discloses a soil-less cultivation method for shallots. The soil-less cultivation method includes the steps that 1) shallot seeds with the good excellent quality are selected; 2) plastic cultivation boxes with the length of 60 cm, the height of 45 cm and the width of 25 cm are selected for cultivation; 3) warm water at the temperature of 20 DEG C is sprayed every day, shallots are illuminated for 3 h to 4 h every day through an LED intelligent illuminating system for shallots, the treated shallots are transplanted to the outside and cultivated after one week and subjected to sunlight illumination for 3 h to 5 h every day; 4) potassium nitrate, magnesium sulfate, ammonium dihydrogen phosphate, ferrous sulfate, calcium nitrate, EDTA iron, manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate and water are prepared into shallot soil-less-cultivation nutrient liquid; 5) the nutrient liquid prepared in the step 4) is diluted to be 15% in mass concentration and continuously sprayed to shallot seedlings for 8 d to 12 d; 6), the nutrient liquid prepared in the step 4) is diluted to be 35% in mass concentration and continuously sprayed to shallot seedlings for 15 d to 30 d.
Description
technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for soilless cultivation of shallots. Background technique [0002] At present, compared with the developed countries in the world, the level of agricultural modernization in my country is still relatively low. Soilless cultivation technology is one of the better solutions to ensure modern agriculture. However, starting from the current situation in our country, the northern region represented by Beijing has a high concentration of calcium and magnesium ions in the water quality, and the EC value is as high as about 1.0ms / cm. It is not suitable for the development of hydroponic technology, which requires local materials and the development of soilless cultivation technology according to local conditions. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art and actual conditions, the invention provides a kin...
