The seedling substrate is an important part of the factory seedling(2 gallon nursery pots supplier), which provides the required environmental conditions such as water, nutrients and oxygen for the growth and development of the seedlings. At present, the planting tray seedling substrate mostly adopts a composite matrix prepared by peat soil, perlite, vermiculite, etc., and the production cost is high, and the peat soil is a non-renewable natural resource, and a large amount of mining will destroy the ecological balance(plastic nursery pots). Screening low-cost, high-efficiency plug seedling substrates is of great significance in production.

(cheap plastic 21 cell plug trays wholesale suppliers usa)It is cheap and easy to take, saves costs, and can turn waste into treasure(1 gallon nursery pots supplier), protect the environment, and has great application value in production. In this study, a variety of peat soil and vermiculite were used in the coastal area to replace some peat soil and vermiculite to carry out the experiment of sweet pepper plug seedlings, aiming at screening the breeding substrate with low cost and good effect, and popularizing vegetable planting seedlings(plastic nursery pots wholesale). Provide effective and feasible ways to promote the industrialization of vegetable industry in Guangzhou.
The test was carried out in the nursery greenhouse of the Academy of Agricultural Sciences(cheap 7 gallon plant pots). The sweet peppers were planted in the trays. The size of the trays was 52 cm × 28 cm × 5 cm, 32 holes per plate, and the hole size was 6 cm × 6 cm × 5 cm. The initial EC value was 0.2mS·cm-1. The nutrient solution prepared according to the Japanese Yamazaki nutrient solution formula was used once in the morning and evening(black plastic nursery pots). The amount of leaching solution was determined according to the weather, seedling growth and substrate water content, and the EC value increased with the growth of seedlings. Increase to 1.2 mS·cm-1 before transplantation.
(cheap plastic 21 cell plug trays wholesale suppliers usa)The matrix ratio was set up with 8 treatments (Table 1), 3 replicates, 20 seedling trays per plot(2 gallon nursery container wholesale price), and the conventional vegetable seedling substrate ratio peat soil: perlite: vermiculite = 3:1:1. On the 20th and 30th day after sowing, 10 seedlings were randomly selected from each plot, and the plant height, stem thickness(15 gallon nursery pots wholesale), leaf number, maximum root length, fresh and dry quality of the plants were determined, and the leaf size, leaf color and root number were visually described. ,tidiness.
In recent years, with the progress and development of China's facility agriculture(cheap 2 gallon plant pots), vegetable factory seedlings have received more and more attention. The plant height is the length from the base of the plant to the heart leaf, and the stem diameter is measured at 1 cm from the substrate surface. The fresh quality and dry mass are the average values before and after drying of 10 seedlings per plot(plastic nursery pots manufacturers). The matrix ratio seedling substrate is prepared by peat soil, perlite, vermiculite, wood chips, coco peat, river sand, etc., by volume ratio.
(cheap plastic 21 cell plug trays wholesale suppliers usa)One hole of pre-promoted sweet pepper seed is planted in each hole(cheap 1 gallon plant pots). When the seedling grows out of the true leaf, a natural degradable, pure natural organic coco peat can be used as a vegetable seedling substrate during the processing of the local coconut shell fiber. The tested varieties of sweet peppers for the tested varieties were Carlton, which was supplied by France Greens Seed Company. Plant growth index was determined(wholesale nursery pots). On the 3rd, 4th and 5th day after sowing, 5 seedling trays were randomly selected from each plot to investigate the emergence rate.
