Problems solved by technology

However, different plants require different nutrients. It is necessary to scientifically and rationally prepare the nutrient solution suitable for each plant according to different plants, so as to avoid the waste of nutrient solution and recycling costs, and to avoid the rotten roots of plants soaked in water for a long time. To avoid pests and diseases, how to make full use of nutrient solution components to increase production, reduce the recovery cost of nutrient solution and shorten the cultivation time to reduce costs is an urgent problem to be solved by soilless cultivation technology

Embodiment 1

[0028] A method for shortening the cultivation time of lettuce, comprising the following steps:

[0029] 1) Boil the rice-washing water and cool to room temperature, then soak the lettuce seeds in the cooled rice-washing water for 3 hours, then fish them out, lay them on gauze, put them in a cool place, and spray them once a day at noon and at night After being germinated in the rice-washing water frozen to 15°C for 6 days, cultivated lettuce seedlings are obtained;

[0030] 2) Lettuce nutrient solution A is made by mixing the following raw materials in parts by weight: potassium sulfate 3, calcium nitrate 10, potassium nitrate 0.5, ammonium nitrate 0.9, urea 0.1, magnesium sulfate 0.5, ammonium dihydrogen phosphate 0.05, zinc sulfate 0.0000002, Boric acid 0.0000012, manganese sulfate 0.0000008, copper sulfate 0.00000003, ammonium molybdate 0.00000002, ferrous sulfate 0.000005, EDTA 0.000008, cyclodextrin 15 and water 1500;

[0031] 3) Add lettuce nutrient solution A into the...

Embodiment 2

[0035] A method for mixed soilless cultivation of lettuce and algae, in which the algae uses extremely large spirulina for mixed soilless cultivation, comprising the following steps:

[0036] 1) Boil the rice-washing water and cool to room temperature, then soak the lettuce seeds in the cooled rice-washing water for 3 hours, then fish them out, lay them on gauze, put them in a cool place, and spray them once a day at noon and at night The rice-washing water frozen to 10°C germinates for 6 days to become cultivated lettuce seedlings;

[0037] 2) Lettuce nutrient solution A is made by mixing the following raw materials in parts by weight: potassium sulfate 5, calcium nitrate 15, potassium nitrate 0.6, ammonium nitrate 1.4, urea 0.2, magnesium sulfate 1.5, ammonium dihydrogen phosphate 0.08, zinc sulfate 0.0000003, Boric acid 0.0000023, manganese sulfate 0.000001, copper sulfate 0.00000006, ammonium molybdate 0.00000003, ferrous sulfate 0.000006, EDTA 0.00001, cyclodextrin 20 and...

Embodiment 3

[0043] A method for mixed soilless cultivation of lettuce and algae The algae selects extremely large spirulina for mixed soilless cultivation, including the following steps:

[0044] 1) Boil the rice-washing water and cool to room temperature, then soak the lettuce seeds in the cooled rice-washing water for 3 hours, then fish them out, lay them on gauze, put them in a cool place, and spray them once a day at noon and at night After being germinated in the rice-washing water frozen to 15°C for 5 days, cultivated lettuce seedlings are obtained;

[0045] 2) Lettuce nutrient solution A is made by mixing the following raw materials in parts by weight: potassium sulfate 4, calcium nitrate 12, potassium nitrate 0.5, ammonium nitrate 1, urea 0.1, magnesium sulfate 1, ammonium dihydrogen phosphate 0.05, zinc sulfate 0.0000003, Boric acid 0.0000020, manganese sulfate 0.000001, copper sulfate 0.00000005, ammonium molybdate 0.00000003, ferrous sulfate 0.000006, EDTA 0.000008, cyclodextri...

Abstract

The invention discloses a method for shortening the cultivation time of leaf lettuce, which comprises the following steps of: 1) accelerating germination and cultivating bud raising of seeds of the leaf lettuce to obtain cultivation seedlings of the leaf lettuce; 2) preparing a leaf lettuce nutrient solution A by mixing the following raw materials: potassium sulfate, calcium nitrate, potassium nitrate, ammonium nitrate, urea, magnesium sulfate, ammonium dihydrogen phosphate, zinc sulfate, boric acid, manganese sulfate, copper sulfate, ammonium molybdate 3, ferrous sulfate, EDTA, cyclodextrin and water; 3) adding the leaf lettuce nutrient solution A into a transparent cultivation box, introducing algae seeds, and then planting the leaf lettuce cultivation seedlings on a planting layer, wherein the temperature is controlled to be 20-25 DEG C, the planting layer is in contact with the leaf lettuce nutrient solution A but not soaked, and spraying the nutrient solution A to the seedlings every day; 4) adding a leaf lettuce nutrient solution B in the middle stage of planting, and spraying a mixed nutrient solution every day; and 5) not carrying out foliar spraying in a later stage. Themethod for shortening the cultivation time of the leaf lettuce can not only achieve full utilization of the nutrient solution, but also get double harvests of the leaf lettuce and the algae.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, more specifically, the invention relates to a method for shortening the cultivation time of lettuce. Background technique [0002] Human beings are paying more and more attention to food safety, and pesticides and chemical fertilizers are unavoidably used in the natural planting process of vegetables. If chemical fertilizers are abused, it will easily lead to an imbalance of soil nutrients, and even destroy the health of soil and groundwater. Soilless cultivation is a method that does not use natural The method of cultivating plants with soil is a closed cycle system, which is completely controllable. Harmful substances are not allowed to be used in the soilless cultivation system. The nutrient solution is recycled and is not allowed to be discharged into the environment. Therefore, soilless cultivation can not only produce completely Green and harmless food can also effectively prot...
