Traditional seedling substrates are usually prepared from grass charcoal, vermiculite and perlite in a certain proportion(black plastic nursery pots). However, peat is a non-renewable resource, and rational development of cheap and practical matrix substitutes has become a hot spot in agricultural and horticultural research. Coco peat is a new soilless culture material made from coconut shell outer fibe(14 gallon nursery pots wholesale)r. It has high water retention capacity and good drainage capacity, suitable pH, good flexibility, degradable, renewable, and low price. .

(cheap plug trays wholesale supplier canada)At present, it has been researched and applied in the production of fruit and vegetable crops such as melon cucumber and sweet pepper, but the application on tomato seedlings has not been reported. In this experiment, tomato varieties were used as test materials to compare the effects of different ratios of coconut and grass charcoal as main components on tomato seedlings, in order to provide a basis for the application of coco peat in tomato seedlings(10 gallon nursery pots wholesale). The principle of “agricultural prevention, physical control, biological control, supplemented by chemical prevention and control” is adhered to in prevention and control.


Agricultural control: the nursery field is far away from the vegetable planting field(plastic nursery pots wholesale), and the high-resistance and multi-resistant varieties, seeds and seedling equipment are used for disinfection treatment, and the weeds inside and around the nursery facilities are removed. If the organic matter in the seedling substrate organic material is fully fermented, scientific fertigation , avoid rain and nursery, mix the substrate to choose clean and pathogen free(7 gallon nursery pots wholesale). Physical control: nursery facilities in the summer, the high-temperature shack in the seedling period, the vents are closed with insect-proof nets, and the seedbed is hung on the seedbed.(cheap plug trays wholesale supplier canada)


Biological control: Inoculation of plant growth-promoting bacteria(plastic nursery pots manufacturers), spraying of plant sources or biological source preparations in the seedling substrate. Chemical control: For the main pests and diseases in the seedling stage, the chemical pesticides with low toxicity and low residue should be selected according to the requirements of gram B 4258 and gram B/T 8321. In summer and autumn, it is advisable to use the shade net cover and the wet curtain fan system to maintain the temperature required for normal growth and development of the seedlings(5 gallon nursery pots wholesale). The light intensity gradually increases with the seedling development stage.


In the second stage of summer, in order to prevent glare from burning the seedlings, the shade net should be covered(plastic nursery pots). The V stage should be close to the natural light intensity. The grass charcoal is selected from the northeast grass charcoal soil, the vermiculite (diameter 1~2 mm) and the perlite (diameter 3~5 mm) are produced by the Xinyou County Xinyou Mineral Processing Factory in Hebei Province, and the 105-hole tray is used for tomato seedling cultivation(3 gallon nursery pots wholesale). The experiment consisted of 7 treatments (Table 1). The tomatoes were run on a dry seed, and the seeds were placed on a seedling bed frame after sowing.(cheap plug trays wholesale supplier canada)


The ambient temperature in the greenhouse is 28 ~ 30 ° C / 18 ° C (day / night), using erludan (NPK 20-20-20) balanced fertilizer aqueous solution as a nutrient solution(wholesale nursery pots), spray once every 3 to 5 days, seedling period Management is consistent. After 30 days of sowing, the relevant indicators were randomly sampled and repeated three times for each treatment. In this test, the bulk density, total porosity(2 gallon nursery pots wholesale), pH value and EC value of each treatment matrix were within the suitable range of the seedling substrate by analyzing the physical and chemical properties of different proportioning substrates.
