Problems solved by technology

[0004] The existing soilless culture system adopts a large one-time investment, and cannot accurately control the amount of irrigation and fertilization, resulting in low water and fertilizer utilization.
However, the cost of existing methods for cultivating seedlings without soil is relatively high, and the requirements for managers of soilless cultivation are relatively high.

Embodiment 1

[0036] A soilless cultivation system integrating water and fertilizer, which includes a seedling raising system, a planting system and a water and fertilizer spraying system;

[0037] The seedling raising system includes a seedling raising shed, a seedling raising bed is arranged in the seedling raising shed, an antirust iron net is laid on the seedling raising bed, and some seedling raising trays are arranged on the seedling raising bed on the antirust iron mesh; wherein the seedbed is selected from 30mm×30mm hot-dip galvanized Angle iron, make a seedling bed frame with a growth of 30m, a width of 1.4m, and a height of 0.8m, install beams every 1.5m, and lay a layer of anti-rust iron net on the seedbed frame; 54cm, width 28cm, hole depth 45mm, diameter 40mm×40mm, bottom 20mm×20mm, capacity 40cc;

[0038] The planting system includes a planting shed. Several planting frames are arranged in the planting shed. Passages are provided between every two adjacent planting frames. Sev...

Embodiment 2

[0042] Utilize the method for cultivating lettuce of the integrated soilless cultivation system of water and fertilizer described in embodiment 1, its concrete steps are as follows:

[0043] 1) Seed selection: Germination rate testing is required before seedling cultivation, and lettuce varieties that are disease-resistant, high-yield, good in marketability and suitable for market demand are selected;

[0044] 2) Seedling-raising substrate preparation: Take coconut peat bricks and soak them in water at a ratio of 1:5 one day in advance to make them fully absorb water and swell for later use. Stand-by in the seedling tray of 72 holes;

[0045]3) Seed disinfection treatment: in the first step, soak the seeds in warm water at 50°C for 20 minutes, in the second step, soak the seeds in 10% trisodium phosphate solution for 20 minutes, and wash them twice with water; ‰ Dressing with Liangdun suspending agent and drying in the air;

[0046] 4) Sowing: Sow the dried seeds in the seed...

Abstract

The invention discloses a water and fertilizer integrated soilless culture system and a culture method. The system comprises a seedling growing system, a planting system and a water and fertilizer spraying system; the method comprises steps of seed selection, seedling substrate preparation, seed disinfection treatment, seeding, seedling stage management, cleaning and disinfection of planting pipelines and nutrient solution pond, management after transplantation, seedlings transplantation, attenuation of nutrient solution, and the like. The device adopts an irrigation and fertilization method of uniformly, accurately and directly conveying fertilizer solution to substrate adhered to roots of plants with small flow through a pipeline system and emitters mounted on the planting pipelines, can quantificationally, periodically and directly feed water and nutrient to the plants according to growth requirements of the plants, and improves utilization factors of water and fertilizer.

Description

technical field [0001] The invention relates to a soilless cultivation technology, in particular to a soilless cultivation system and a cultivation method integrating water and fertilizer. Background technique [0002] Grain and vegetables are the material means of subsistence necessary for human beings to survive. my country is a large agricultural country and a populous country. The annual consumption of food and vegetables is a huge number. Traditional food and vegetables are grown in the soil. However, with the development of human society, the area of ​​cultivated land is shrinking day by day. To ensure people's demand for food and vegetables, it is necessary to rationally use cultivated land and combine new planting methods. [0003] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling tec...
