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 Sagittarius bulbs with typical characteristics of the variety, moderate size, full maturity, curved and thick terminal buds, and no damage from diseases and insect pests. Cut off the terminal buds from the connection between the terminal buds and the bulbs, and Note that there are no stems on the cut-off terminal buds. After washing with clean water, put them in saturated bleaching powder solution and soak for 60±10 minutes. After taking them out, rinse them with tap water. Store in refrigerator or freezer for later use.

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

[0020] (3) During the period from April to May of the second year, soak the matrix in the water-permeable packaging bag in a pond or ditch, take the matrix out of the water the next day, and dry it until the matrix can be "han...

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 Sagittarius mainly involves the following contents: [0003] (1) Preservation of seed buds. There are mainly two ways, one is to cut the buds of the selected remaining seed bulbs before winter, and save the cut terminal buds by sand layering. That is, choose a cool and ventilated place to dig a small hole, spread fine sand, and then put arrowroot buds. A layer of sand and a layer of buds are piled up in layers to keep the implants from being exposed to light, and try to control the ambient temperature below 15°C. The other is to reserve the bulbs in the field, keep the minimum water level in the field not lower than 10cm in winter, and directly use the whole bulbs for sowing and raising seedlings when raising seedlings. There are some problems in the application of these two ways....
