Suspended groove type potato soilless culture method

Abstract

The invention relates to a suspended groove type potato soilless culture method. The suspended groove type potato soilless culture method includes the steps of arrangement of soilless culture medium grooves, preparation of soilless culture mediums, efficient and saving type grafting and plant management, wherein the step of efficient and saving grafting comprises seedling nursery, novel scion preparation, grafting and healing cultivation; the step of plant management comprises field planting, pruning, flower and fruit management and plant shape control. By means of the soilless culture mediumgrooves, the suspended groove type potato soilless culture method can overcome the shortcomings of poor water-retaining property and difficulty in control of temperature of water and fertilizer application and give full play to the characteristics of culture mediums; by means of the efficient and saving type grafting and the supported plant management, the suspended groove type potato soilless culture method can optimize plant configuration, simplify operation of plant management and improve the utilization rate of planting space; the suspended groove type potato soilless culture method well conforms to the general trend of water and fertilizer integrated application and irrigation, enables fertilizer and water supply to meet the demands of plant growth, improves the utilization rate of water and fertilizers, gives full play to the high yield potential of potato, achieves high yield and quality and further promotes development of the potato industry.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a tomato suspension trough type soilless cultivation method. Background technique [0002] Tomato is rich in protein, sugar, minerals and rich vitamins. It is rich in nutrition and delicious in flavor. Its per capita consumption ranks first among vegetable crops, and it is an important facility cultivated crop. Tomato grows fast, branching and fruiting ability is strong, but in the production process, it is easy to encounter problems such as incoordination of vegetative growth and reproductive growth, unreasonable water and fertilizer supply, and falling flowers and fruits. Therefore, plant management and fruit loss must be carried out in the process of cultivation. Fertilizer and water management, improve the plant environment, coordinate the relationship between sinks and sources, regulate the direction of nutrient operation, improve water and fertilizer utilization, ...

AI Technical Summary

Problems solved by technology

Soilless cultivation substrate bags are widely used in soilless cultivation of tomatoes because of their advantages such as good air permeability, easy drainage, and not easy to damage roots. However, with the production of tomatoes, more and more water and fertilizer integrated systems are used for fertilization and irrigation. , some disadvantages of matrix bags are gradually exposed

Substrate bags have poor water retention and consume too much water, which leads to increased costs; the temperature and humidity in different parts are unstable and unbalanced, and it is difficult to grasp the law of fertilizer and water use; in addition, the use of substrate bags cannot simplify the cultivation and management procedures of tomatoes, and the manual input of plant management still big
