How to grow tomatoes? Detailed explanation of soilless culture techniques for tomatoes
The market demand for tomatoes has always been good, the taste is sweet and sour and the nutritional value is high. Therefore, recently, many vegetable farmers have consulted on how to carry out soilless cultivation of tomatoes. The following small series is a simple technique for soilless cultivation of tomatoes.
First, the facilities conditions
Soilless cultivation requires cultivation tanks, irrigation facilities, etc. The cultivation tank is the basic point of everything, because it is the place where crops grow, and it is generally best to prepare a irrig for every three to five cultivation tanks, so that it can be replenished at any time. The moisture of the tank. The height of the reservoir is higher than the cultivation tank so that the water level can be controlled.
Second, the cultivation substrate
Tomato is one of the technical key points of soilless culture. It is the cultivation substrate. The nutrients needed for tomato growth depend on the cultivation substrate. Generally, the cultivation substrate should be organic. For example, the straw of corn and other crops can be crushed and the organic fertilizer is decomposed. Then mix with the slag, and finally add some tomatoes for soilless cultivation. Corn stalks and organic fertilizers account for 40% each, and slag accounts for 20%. After they are formulated, they are then sterilized by high temperature sterilization, and finally they can be filled into tomato cultivation tanks.
Third, nursery
In order to increase the germination rate of tomatoes, the tomato seeds should be treated first before sowing. Method: soak the tomatoes in soda water with very low concentration for 30 minutes (to eliminate the bacteria and viruses on the surface of the seeds), then remove the seeds and wash them. Net, put in a plastic bag or wet towel, and then placed in a greenhouse environment of 25 to 28 degrees, and then sown after germination. Remember to be even when planting, not dense. The temperature after sowing should be kept at 25 to 30 degrees.
Fourth, colonization
When the tomato seedlings grow three to four true leaves, they can be planted. Before the planting, the substrate in the cultivation tank should be filled flat, and then the substrate such as watering should fully absorb the water, and then dig the hole for colonization. It is recommended that each cultivation tank be made in two rows with a row spacing of about 25-35 cm.
V. Cultivation management
Management after planting is also important, especially for light and temperature. Generally, tomatoes have a suitable growth temperature of 10 to 28 degrees, 20 to 25 degrees Celsius during the day and 10 to 15 degrees Celsius in the evening. Fertilization is required in the 20 days after planting. Each tomato can be applied within 15g of special fertilizer.
In summary, the soilless culture model is now more popular than before. The quality of tomatoes grown in soilless culture is high and the yield is high. Different from the traditional cultivation mode, there are many pests and diseases. Therefore, the vegetable growers who want to learn soilless cultivation techniques must first put the technology first. Support to fight.
