The soilless cultivation of tomato solid matrix is ​​simple in form, efficient and durable, safe and convenient. In addition to the construction of cultivation tanks and supporting irrigation equipment, it is similar to the cultivation of facilities vegetables in other aspects, and it is easy to carry out the existing greenhouses, greenhouses and other facilities. The transformation and upgrading of solid substrate cultivation can fundamentally solve problems such as soil-borne diseases and insufficient cultivated land. The soilless cultivation technology of tomato solid matrix was used in the production test and demonstration of hundreds of acres in Shijiazhuang Gaochun and Langfang Gu'an. The results show that this technology can not only replace the traditional soil cultivation, but also produce high-quality products with remarkable efficiency. Among them, the supporting technologies such as biological control, bumble bee pollination, and yellow (blue) board trapping and killing are used to reduce the average input of pesticides to 1,000 yuan per mu, which is more than 50% more than traditional flood irrigation and water saving per mu. The labor cost is more than 5,000 yuan, and the output is increased by 10%-15%. The technical points are as follows: First, cultivation tank construction The cultivation trough frame adopts a standard brick of 24 centimeters, 12 centimeters, and 5 centimeters in diameter. The trough has an inner diameter of 48 centimeters and a height of 20 centimeters. The length depends on the width of the greenhouse (greenhouse) ( Second, cultivation matrix preparation Cultivation substrate organic matter 40%-50%, bulk density 0.35-0.45 g/cm3, maximum water holding capacity 240%-320%, total porosity 85%, carbon: nitrogen 30:1, pH 5.8-6.4, total nutrients Content 3-5 kg/m3, matrix thickness 15 cm; coarse matrix particle size 1-2 cm, thickness 5 cm. Reference ratio: peat: slag = 4:6; slag: mushroom residue: corn stalk = 3:4:3; slag: mushroom residue: sawdust = 3:5:2. The material of the matrix can be selected widely, and it can be adapted to local conditions, locally sourced, and make full use of local resources with abundant and low-cost raw materials; the raw materials of the matrix should be disinfected, and the solar energy disinfection method and chemical reagent disinfection method can be used; the crude matrix is ​​mainly used as water storage and drainage. Crude slag, gravel, etc. can be used to isolate the woven fabric from the cultivation substrate. The total amount of cultivation medium is 30 cubic meters per mu. Third, the water supply system The head pressure of the source water is 1-3 meters water column, the drip irrigation tube flow rate is 12-22 liters/hour, and the water supply amount is 400-600 milliliters per hole for 10 minutes. The water outlet method is double micro spray, and other drip irrigation forms are also available. The water supply source can be tap water with a suitable pressure, a greenhouse tank with a height of 1.5 meters, a pump with a power of 1100 watts and a water outlet diameter of 50 mm. Fourth, nutrient supply The solid slow-acting fertilizer was used instead of the nutrient solution. The solid fertilizer was formulated with nitrogen:phosphorus:potassium=l:0.25:1.14. The basal fertilizer evenly mixed in the matrix, which accounted for 37.5% of the total fertilizer, and the top dressing was applied in different stages. Solid base soilless cultivation special fertilizer can also be used.
