Soilless cultivation of aquatic vegetables

The aquatic vegetables suitable for indoor soilless cultivation are lettuce, celery, coriander, Chinese cabbage, rape, hollow cabbage and so on. Soilless planting can use discarded plastic boxes as planting pots, then put in about 1 jin of gravel and 1.5 kilograms of perlite; soak the seeds in 32 ℃ of warm water for about 6 hours, dig holes in the substrate, and finally sow seeds along the trenches. In the process of vegetable growth, diluted nutrient solution should be irrigated every 2 days and watered twice a day.

First, select vegetable varieties

1. The main fruits and vegetables suitable for indoor soilless cultivation are strawberry, cherry, cucumber, balsam pear, tomato, radish and so on, while leafy vegetables mainly include lettuce, celery, coriander, Chinese cabbage, small rape, hollow cabbage and so on.

2. The ripening period of vegetables planted in soilless soil is also different, the ripening period of fruit and vegetables is about 3-5 months, that of leaf vegetables is about 2-3 months, and the temperature of general fruits and vegetables should be kept at about 10-25 ℃.

3. Soilless cultivation of vegetables needs to ensure adequate light throughout the day. Generally, leafy vegetables do not require so much temperature, so they are very suitable for indoor planting. Vegetable seeds are generally sold in local farmers' markets.

Prepare the planting basin

1. You can use unused plastic flowerpots and styrofoam boxes as planting pots, but you need holes and trays at the bottom, pay attention to not using earthen pots, and then put 1 jin of pottery gravel and 1.5 kilograms of perlite, which can be purchased in general building materials stores.

2, or vermiculite, peat, rock wool can also, and then add concentrated nutrient solution is divided into No. 1 and No. 2, need to be diluted before use.

Soaking seeds and sowing seeds

1. Select high-quality and strong seeds, soak the seeds in 32 ℃ warm water for about 6 hours, and then soak the gravel and perlite in clean water for use.

2. Then dig the cave with the plastic cup filled with soaked matrix, plant 2 seeds in each hole for fruit and vegetables, dig a ditch for leafy vegetables to sow seeds along the trench, then cover them with matrix and gently press them, and finally cover them with a thin film to wait for seedlings to emerge.

IV. Post-management

The main results are as follows: 1. After seedling emergence, diluted nutrient solution should be irrigated 1-2 times a day. It is appropriate to pour diluted nutrient solution into the tray. Thinning seedlings should be carried out when the seedlings grow 2 leaves. On average, only one seedling can be left in each hole, and the excess seedlings can be pulled out.

2. in the later stage, when the seedlings grow to about 4 true leaves, it is necessary to change the basin for the seedlings, generally sprinkle a layer of soaked gravel at the bottom of the basin to facilitate drainage, then sprinkle a small amount of perlite, and then transplant the seedlings together with the matrix into a large basin. Sprinkle a layer of ceramic gravel on the perlite.

3. After transplanting, the seedlings should be irrigated with diluted nutrient solution, and the first time should be completely watered with oozing water from the planting tray. Generally, leafy vegetables should be irrigated with diluted nutrient solution once every two days, twice a day, and fruits and vegetables twice a day.
