Problems solved by technology

There are some problems in the application of these two methods. The first method needs to dig a hole when saving, and the workload is relatively large.
The second method will occupy a large amount of cultivated land when it is applied, which will affect the efficiency of cultivated land use
This method of raising seedlings, on the one hand, requires a lot of labor and labor intensity, on the other hand, the seedling field occupies a crop growth period of one season, and the land use rate is low

Embodiment Construction

[0018] (1) In mid-to-late November, select Cigu bulbs with typical characteristics of the variety, moderate size, full maturity, curved and thick apical buds, and no pests and diseases, and cut off the apical buds from the junction between the apical buds and the bulbs. Note that there are no stems on the cut top buds. After washing with water, immediately put them in saturated bleaching powder solution and soak for 60±10 minutes. After taking them out, rinse them with tap water. After drying until the surface is dry, place them at 0~5℃. Keep in cold storage or freezer for later use.

[0019] (2) Prepare the substrate and seedling tray. Purchase a substrate that meets the NY / T 2118-2012 standard, and purchase a seedling tray (length × width × height = 60 cm × 20 cm × 4 cm).

[0020] (3) From April to May of the second year, soak the substrate in the water-permeable packaging bag in a pond or ditch. The next day, take the substrate out of the water and dry it until the substrate ca...

Abstract

The invention discloses a soilless seedling culturing method of arrowheads and belongs to the technical field of agriculture, in particular vegetable cultivation. The soilless seedling culturing method includes cutting off terminal buds free of tuber at the joint of the terminal buds and the seedball before winter of the first year, soaking the terminal buds in saturated bleaching powder after cleaning, washing by tap water and refrigerating after drying; vertically inserting the terminal buds into a matrix soaked with water in the second year, disposing a seedling cultivating tray at 20-25 degrees Centigrade for 16 hours of light period, cultivating under the condition of 2000-3000 lux of light intensity and transplanting the seedlings to the field until the arrowhead seedlings grow with 2 to 3 leaves. The seedlings are cultivated under the controllable cultivating condition, and the integral seedling cultivation time is shorter than 25 days; on one hand, labor can be saved, and management is facilitated; on the other hand, season limits are broken through, and technical basis is provided for industrial cultivation and year-round cultivation of the arrowheads.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, especially vegetable cultivation. Background technique [0002] The traditional method of raising seedlings of auntie mainly involves the following: [0003] (1) Seed bud preservation. There are two main ways. One is to cut buds on the selected bulbs before winter, and save the cut top buds with sand stratification. Dig a small pit in a cool and ventilated place, spread fine sand, and then put the buds on the buds. A layer of sand and a layer of buds are layered to keep the seed teeth out of light. Try to keep the ambient temperature below 15°C. The other is to reserve the bulbs in the field, keep the lowest water level in the field at a depth of not less than 10cm in winter, and directly use the entire bulbs for sowing and seedling cultivation. There are some problems in the application of these two methods. The first method requires digging during storage, which requires a lot of work. The sec...
