Cheap Fabric Grow Bags Manufacturers Poland

The size of the disc is 54 mm × 280 mm, because the diameter of the holes is different, the number of holes is between 18 and 800(40 cell propagation trays wholesale). Plug seedling is an important link in vegetable production, which is of great significance to the follow-up link of vegetable production(50 cell tray). PS anti-oxidation, waterproof and moisture-proof, and the total yield increased by 15.3%; mildew and moth proof, effective flame retardant, long-lasting performance.

However, in vegetable seedling raising(50 cell seedling trays wholesale), different plug specifications should be selected for different vegetable varieties, which is also one of the key technologies for vegetable plug seedling subdivision. Polystyrene materials are mostly used in vegetable seedling tray, which has the characteristics of anti embrittlement, aging resistance and deformation resistance(72 cell flats). Polystyrene foam tray can also be used for floating seedlings.(cheap fabric grow bags manufacturers poland)

Standard vegetable seedlings generally use 50 ~ 288 hole tray(51 cell propagation trays wholesale). 32 holes and 50 holes are used to cultivate melon seedlings, such as watermelon, cucumber, balsam pear, melon, Hami melon, etc.; 72 holes are used to cultivate eggplant and fruit seedlings, such as pepper, eggplant, tomato, etc.(120mm plastic grow pots); 105 holes and 128 holes are used to cultivate leafy vegetables (Cruciferae), such as lettuce, cabbage, cabbage, Shanghai green, pine flower, broccoli, etc.

The inner side of round hole is smooth, and there is no right angle around it(104 cell propagation trays wholesale), which is conducive to plant root root root setting and root packing, which is more suitable for the growth of small seedling crops; The four corners of square hole also changed from the original right angle to round corner(heavy duty plug trays). The results showed that the vegetables suitable for seedling transplanting in North China were eggplant, melon, cabbage, etc.

(cheap fabric grow bags manufacturers poland)The substrate contained in the square hole was about 30% more than that in the round hole(128 cell plug trays supplier), the water distribution was more uniform, the seedling root system development was more sufficient, and the square hole was often used in the seedling raising of vegetables with large seedling age(12.5cm plastic grow pots). The hardness of 1.0 ~ 1.2mm plug is good, which is suitable for machine or seeding line operation, and can be reused after disinfection.

For eggplant plug seedlings sown on August 18(40 cell plug tray wholesale), the early maturity of 32 hole plug seedling was 5 days earlier than that of 50 hole plug seedling, the common plug material thickness in the market was mostly 0.6 ~ 1.2mm, and the plug with 0.6 ~ 0.8mm thickness had low price and poor hardness, which was mostly used for artificial sowing and one-time use(germination tray price). The 50 and 72 hole plug almost had no obvious effect.

The seedlings of fruit vegetables can be roughly divided into winter, spring and summer and autumn according to the sowing season(2.5inch square nursery pots). Winter and spring seedlings generally require longer seedling age and larger seedlings, which can be harvested as soon as possible after planting(72 cell plant tray); seedlings in summer and autumn need relatively young seedlings with high root activity, which is conducive to slow seedling after planting.(cheap fabric grow bags manufacturers poland)

In spring, 105 hole plug restricted the root development of tomato and cucumber(3.5inch square nursery pots), reduced the photosynthetic electron transfer rate of leaves, and reduced the biomass and seedling index of vegetables. Considering the economic cost and production efficiency, the 105 hole plug could be used as the suitable seedling diameter(v15 nursery pots). The hole shape of seedling tray is mainly round and square(mainly eggplant and melon).
