Problems solved by technology

However, in the process of outdoor soilless cultivation, the diseases and insect pests brought by rainwater and air will have a significant impact on the growth and firmness of tomatoes
[0003] In order to provide high-quality and safe fresh tomatoes to the market every year, two important problems need to be solved. One is to solve the problems of soil-borne diseases and insect pests in greenhouse cultivation of tomatoes and soil deterioration in greenhouses; the other is to solve the problems of natural diseases and insect pests in outdoor soilless cultivation problem, the problem of nutrient loss caused by too much rain
Have not seen identical technical scheme report before this application proposes

[0026] 1. Tomato seedling cultivation and disinfection in the greenhouse

[0027] Soak the ruby ​​seeds of a high-yield red tomato variety for 2 days, then culture them in water on a sand base for 20-25 days, and the seedlings can be planted when the height reaches 8cm. First, in the greenhouse, 1kg of dichlorvos and 5kg of sawdust were used per mu and mixed and sprinkled on the aisle, and the disinfection time was 12 hours. Spread 5kg of dry straw on the ground, spread 5kg of sawdust on the straw, put 1kg of sulfur on top, close the door and vent, light the straw and fumigate for 12 hours.

[0028] 2. Planting tomato seedlings

[0029] After fully sterilizing and killing insects in the greenhouse, the substrate in the cultivation tank has been treated at a high temperature of 70°C for 7-10 days, and planted according to the specifications of a plant spacing of 60cm and a row spacing of 30cm, about 2,000 plants per mu, and set up a support. The tomato adopts the single-stem p...

Abstract

The invention discloses a method for cultivating tomatoes in a greenhouse in a soilless mode. The method comprises the steps of designing cultivating grooves, preparing a substrate, sterilizing the substrate, preparing and applying a nutrient solution, and conducting comprehensive tomato cultivation management. A half of each cultivating groove is buried into soil, so that a great number of materials is saved. The substrate is divided into two layers. All the underground substrate is furnace slag. The substrate used on the ground is flammulina velutipese residues. The substrate has a large porosity, so that respiration, extension, water absorption and nutrient absorption of root systems are facilitated. The substrate is sterilized at the temperature higher than 70 DEG C, and the main target is the tomato mosaic disease. When tomatoes are cultivated according to the method for cultivating tomatoes in the greenhouse in the soilless mode, the use amount of pesticide and fertilizer and labor cost are reduced, and the tomato yield, the content of carbohydrate and the content of Vitamin C are all greatly increased. According to the method for cultivating tomatoes in the greenhouse in the soilless mode, the practicability is high, and high economic value is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of soilless cultivation, and is closely related to soilless cultivation substrate, facility agriculture and pollution-free green food cultivation technology. 【Background technique】 [0002] Tomato is an economic crop with high market demand, high nutritional value and economic value. Planting tomatoes in greenhouses and reasonably adjusting the time to market of tomatoes is an effective way to improve the efficiency of tomato planting. However, due to long-term continuous cropping, severe pests and diseases, lack of some soil nutrients and deterioration of physical and chemical properties, the decline in tomato yield and quality, and the use of a large amount of pesticides and fertilizers in the continuous cropping process have caused great harm to food safety. Soilless cultivation has been widely used in many horticultural crops such as vegetables, fruits, flowers, etc. It can maximize the utilization ef...
