Cultivation method of soilless cultivation water dropwort in greenhouse

Abstract

The invention discloses a cultivation method of soilless cultivation water dropwort in a greenhouse. The method includes seedling cultivation and field planting, and water dropwort seeds are used forsoilless cultivation. The water dropwort seeds are cultivated into strong seedlings which can be safely transplanted in the seedling cultivation process, the strong seedlings are cultivated into finished water dropwort which can be harvested in the field planting process, and primary nutrient solution, strong seedling nutrient solution and cultivation nutrient solution are adopted in the whole cultivation process. The cultivation method of the soilless cultivation water dropwort in the greenhouse is short in seedling cultivation time and high in seedling cultivation success rate, produced transplanted seedlings have developed root systems, the cultivation speed of the soilless cultivation water dropwort is increased, and cultivation cycle is shortened, so that production efficiency is improved. Besides, occupied area is reduced by cultivation in the greenhouse, planting and harvesting are facilitated, the problem of water area pollution in external water area planting is solved, the water dropwort seeds instead of traditional asexual reproduction seedlings are adopted in the seedling cultivation process, the seedling cultivation process is simplified, and the seedling cultivation success rate and seedling cultivation quality are improved.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a method for cultivating cress in a greenhouse without soil. Background technique [0002] With the rapid development of science and technology, people have higher requirements for the efficiency and quality of production. In agriculture, traditional soil cultivation technology is widely used, but the pollution of soil cultivation to crops is becoming more and more serious, and crops are easily affected by the soil. The heavy metal ions contained in the soil, and the crops cultivated in the soil are easily affected by diseases, and a large amount of pesticides need to be used, so the pesticide residues on the produced crops will be large, and the production cost will also be increased. [0003] With the use of soilless cultivation technology, due to the great reduction of insect pests, the use of pesticides is reduced, and the crops produced are clean and...

Problems solved by technology

[0002] With the rapid development of science and technology, people have higher requirements for the efficiency and quality of production. In agriculture, traditional soil cultivation technology is widely used, but the pollution of soil cultivation to crops is becoming more and more serious, and crops are easily affected by all kinds of bacteria in the soil. The heavy metal ions contained in the soil, and the crops cultivated in the soil are easily affected by diseases, and a large amount of pesticides need to be used, so the pesticide residues on the produced crops will be large, and the production cost will be increased.

[0003] With the use of soilless cultivation technology, due to the great reduction of insect pests, the use of pesticides is reduced, and the crops produced are clean and will not be polluted by the soil, thus avoiding the problem of cleaning and removing soil when the crops are mature and harvested. The soilless cultivation of cress in the greenhouse improves the land utilization rate and eliminates the problems of the region and soil conditions during vegetable production. At the same time, the working environment of soilless cultivation is clean and the work intensity is low, which avoids the large area of ​​soil cultivation and labor. Intensity is big, the shortcoming that is easily affected by the external environment, so soilless cultivation technology will inevitably become the focus of development in the future, the development time of the soilless cultivation of watercress is very long, but the watercress in the prior art is outdoor cultivation, and the growth rate is slow. Stable, the quality of the harvested cress is greatly affected by the water quality of the cultivation ground, and it is inconvenient to plant and harvest. In order to solve this problem, the present invention provides the following technical solutions
