What are the advantages of plug seedling raising?

Compared with conventional seedling raising, plug seedling raising has the following advantages:

(1) energy-saving, labor-saving, labor-saving and efficient.

Plug seedling cultivation adopts precision sowing and seedling formation at one time. A series of operations such as substrate mixing, pallet loading, sowing and covering are all automatically controlled. The seedling age is shortened by 10 ~ 20 days compared with conventional seedling raising, and the labor efficiency is improved by 5 ~ 7 times. The average per capita management of conventional seedlings is 25,000 plants, and the average per capita management of plug seedlings is 6.5438+0.5 million plants. Due to the high degree of mechanized operation management, the operation intensity and workload are reduced. The average weight of each soil in conventional seedling raising is 0.5-0.75 kg, and each vegetable planted 1 hectare (with an average of 60,000 plants) is equivalent to 30-45 tons of soil removal. Plug seedling raising adopts light substrate.

(2) saving energy, seeds and nursery land

Plug seedling is direct seeding of dry seeds, 1 hole 1 seed, and centralized seedling raising. The coal consumption of ten thousand seedlings is 25% ~ 50% of that of conventional seedlings, saving 2/3 of energy. The number of seedlings per unit area is higher than that of conventional seedlings. According to the number of holes per tray, 3,654.38+0.5 million ~ 654.38+0.8 million plants can be raised per hectare. Using plug seedling can effectively increase the production area of protected land. Taking Beijing as an example, about 40% of the greenhouse area in spring is used for vegetable seedling. Using plug seedling, the greenhouse area in Beijing suburbs can be reduced by 80%, and the production greenhouse area can be increased by 1.5 times, which brings obvious benefits to alleviate the vegetable supply in the capital market.

(3) low cost

Compared with conventional seedling raising, the cost can be reduced by 30% ~ 50%.

(4) It is convenient for standardized management

It is especially suitable for areas lacking seedling raising technology.

(5) Use the plug

Seedling raising, because the stress resistance of seedlings is enhanced, planting does not damage the root system. If the seedlings are bare-rooted, the survival rate will often be affected, while plug seedling raising belongs to block transplanting, so after field planting, the seedlings are delayed quickly and the survival rate is high.

(6) Suitable for long-distance transportation

Plug seedling is based on light substrate and soilless materials. These seedling substrates have the characteristics of light specific gravity, strong water retention and difficult dispersion of roots, and are suitable for long-distance transportation. Plug seedlings are light in weight, each plant weighs only 30-50g, which is 6%- 10% of the conventional seedlings. The foundation has strong water resistance and the root system is not easy to disperse, which can ensure that the seedlings will not die during transportation.

(7) Suitable for mechanized transplanting.

Transplanting efficiency is improved by 4-5 times. It opens up a broad prospect for the mechanization of vegetable production.

(8) Relieve the worries of farmers.

Liberate farmers from "small but complete" agriculture.

(9) It is conducive to the promotion of fine varieties.

Reducing the flood of fake and shoddy seeds is conducive to standardizing scientific management and improving the quality of commercial seedlings. Relieve the off-season market of vegetables and enrich people's food baskets.

The establishment of plug seedling system makes vegetable seedling specialized, seedling supply commercialized and production process mechanized. Therefore, this seedling raising technology is rapidly popularized in developed countries such as Europe and America. Seedling experts from Beijing Vegetable Research Center introduced this technology to China on 1986, and devoted themselves to the research of this technology. At present, more than 40 nurseries have been established in China.
