Storage techniques and post-harvest treatment methods of herbaceous flower seeds?
Herbaceous flowers are mostly strong, and they can reproduce a large area even if they are thrown on the ground, and they do not need too much management, are easy to grow, and look very beautiful, so what are the storage techniques of herbaceous flower seeds? How to deal with the high germination rate after harvest? Is there any way.
First, how to deal with the high germination rate of herbaceous flower seeds after harvest.
1. Do a good job in cleaning and selecting flower seeds
The seeds should be cleaned after harvest. The whole plant should be dried and threshed, and the pericarp, pulp and various appendages should be removed if the fruit is harvested together. Flower seeds are small and light in weight, and some seed coats have short bristles, which are easy to adhere to or mix with life impurities such as sclerotia, galls, eggs and weed seeds, and inanimate impurities such as residual leaves and sediment.
2. Reasonable drying
Herbaceous flower seeds that need to be dried after harvest must be dried together with fruit shells, and do not put the seeds on the cement field or in metal containers to expose them in the sun, otherwise it will affect the vitality of the seeds. The seeds can be dried on canvas, Reed mats and bamboo mats. Some seeds are afraid of light, so the natural wind drying method can be used to place the seeds in a ventilated and rain-proof room to make them naturally dry. In general, the water content of herbaceous flower seeds is less than 7%.
II. Key points of storage technology
1. Choose the right packaging method
Flower seeds are generally small in number, short in life and expensive in price. In most cases, polyethylene aluminum foil composite film bags are used, and the jackets are generally paper seed bags. Flower seeds containing aromatic oil should be stored in metal cans, wooden boxes or colored glass bottles. Canned and aluminum foil bags can also be pumped into vacuum or semi-vacuum when sealing to reduce the amount of oxygen in the container. The name of the seed and the year, month, day and service life of the harvest should be correctly marked outside the seed bag.
2. Low temperature and moistureproof storage
Seeds that have been washed and dried to moisture content and packed in aluminum foil bags or metal cans should be stored in dry, sealed, low-temperature conditions (2Murray 5 ℃). The seed bag or jar should be placed on a shelf or table about 50cm from the ground. Do not contact the seed bag directly with the ground to prevent moisture. A small amount of seeds can be stored in a dryer. The dryer can use glass bottles, small mouth covered urns, plastic buckets, etc., with quicklime, silica gel, dried plant ash and charcoal at the bottom as desiccant, seed bags on top, and then sealed and placed in a low-temperature drying place.
3. Reasonable stacking
There are many varieties and grades of flower seeds, but the general number of seeds is not large. In the warehouse, it should be placed on the platform which is about 50cm from the wall and 50cm from the ground, and make a sign indicating its location, quantity, packaging, etc., in order to prevent confusion.
4. Timely ventilation
Seed respiration produces a lot of heat, timely ventilation can cool down and dissipate dampness. Generally speaking, it is based on the principle of sunny weather, rain and snow, dripping water into ice, opening in the morning and evening, less opening at noon, and fog at night. Ventilation is mostly natural ventilation, conditional mechanical ventilation is available.
5. Diligent inspection
The warehouse should check in time and check the water content and germination rate of the seeds after summer or winter. Set up temperature and humidity meters at multiple points in different parts of the warehouse, set people to measure regularly, and make records. Flower seeds must be stored in a low-temperature and low-humidity environment to prevent mildew or decrease in germination rate.
