Embodiment 1

[0032] 1. A simplified soilless cultivation of Chinese cabbage refers to planting in a facility greenhouse and isolating it from the outside world through insect-proof nets. The hydroponic device comprises a T-shaped nutrient solution input pipeline 1 and a T-shaped nutrient solution output pipeline 2, the nutrient solution input pipeline and the nutrient solution output pipeline communicate with each other through a cultivation pipeline 3, and the cultivation pipeline is along the Several cultivation holes 4 are evenly distributed along its length direction, and the cultivation pipeline is inclined downward by 5° along the direction of the nutrient solution input pipeline to the nutrient solution output pipeline; the nutrient solution input pipeline includes a vertical liquid inlet pipe 5 and Vertical liquid inlet pipe 6, the vertical liquid inlet pipe communicates with the middle bottom of the longitudinal liquid inlet pipe, and the nutrient solution output pipe includes a ve...

Embodiment 2

[0046] In order to study the effects of different treatments on the germination of Chinese cabbage seeds, different seed treatment methods were set up to analyze the germination situation. Seed treatment 1: soaking seeds at 55°C for 8 minutes; 0.1wt% KMnO 4 Soak the seeds for 8 minutes, rinse the seeds with water; soak the seeds for 1 hour at 4°C; soak the seeds for 16 hours at 20°C, and sow. Seed treatment 2: Seed soaking at 55°C for 10 minutes; 0.1wt% KMnO 4 Soak the seeds for 10 minutes, rinse the seeds with water; soak the seeds for 1 hour at 4°C; soak the seeds for 24 hours at 20°C, and sow. Seed treatment 3: Seed soaking at 55°C for 9 minutes; 0.1wt% KMnO 4 Soak the seeds for 9 minutes, rinse the seeds with water; soak the seeds for 1 hour at 4°C; soak the seeds for 16 hours at 20°C, and sow. No treatment is ck. The results showed that the germination status of the treated seeds was obviously better than that of no treatment, and there were some differences among the ...

Embodiment 3

[0050] In order to study the effects of different nutrient solutions on the growth and quality of Chinese cabbage, three groups of different nutrient solutions were set up, T1: N source 16wt%+P 2 o 5 16 wt%+K 2 O 18wt%+TE 50wt%, T2: N source 16wt%+P 2 o 5 16 wt%+K 2 O 18wt%+NiSO 4 0.005%+TE 50wt%, T3: N source 16wt%+P 2 o 5 16 wt%+K 2 O 18wt%+seaweed 0.5wt%+NiSO 4 0.005wt%+TE 50wt%, treated for 1 week to observe the growth of the plants, the results showed that T2 had the most obvious effect on the growth and quality of Chinese cabbage sprouts (Table 2).

Abstract

The invention provides a water culture method for Chinese flowering cabbage and belongs to the field of agricultural production. Chinese flowering cabbages are planted in a greenhouse provided with afly net. According to biological characteristics of Chinese flowering cabbages and insect pest occurrence characters, seedling culture, design and application of water culture devices, efficient culture technique are integrated and optimized full all sides, and thus a simplified water culture device and a water culture method for Chinese flowering cabbages are obtained. By the method, Chinese flowering cabbages reach green standards, have high yield and good quality.

Description

technical field [0001] The invention belongs to the field of agricultural production, and in particular relates to a hydroponic method for Chinese cabbage. Background technique [0002] As modern people have higher and higher requirements for food safety, green vegetables that are pollution-free and free of chemical fertilizers and pesticides are favored by more citizens. Green food is known as a "sunrise industry" and has a broad market. An analysis of a report published by the Food and Agriculture Organization of the United Nations shows that in the past 10 years, in the markets of some countries, the annual sales growth rate of green agricultural products has exceeded 20%. This is in stark contrast to the stagnation of some conventional food markets. The adoption of industrialized seedling cultivation and high-efficiency hydroponics is an important way to obtain green vegetables. [0003] Hydroponic technology is free from the shackles of traditional agricultural techno...
