To this end, eggplant plug seedlings use intelligent(8 cell propagation trays wholesale), engineered, mechanized seedling technology to get rid of the constraints of natural conditions and regional restrictions, to achieve the factory production of vegetables, flowers and seedlings. Then, what are the technical points and methods of eggplant seedling seedling raising(104 cell propagation trays wholesale)? 2 leaves of 1 seedlings with 288 holes, 4~5 leaf seedlings with 128 holes. 5~ 6 leaf seedlings with 72 holes.(bulk buy cheap large hydroponic trays online)
Use charcoal and vermiculite 2:1, or peat and vermiculite plus waste mushroom 1:1:1, covered with vermiculite(wholesale nursery pots). The 288-hole tray has 2.8 m3 of spare substrate for 1000 disks, 3.7 m3 for 128-well trays, and 4.7 m3 for each of the 1000-hole trays. Mix the fertilizer and the substrate evenly, and after the seedlings have 3 leaves and 1 heart, combine the water spray for 2-3 times of foliar spray fertilizer(51 cell propagation trays wholesale). The seed should be tested for germination rate before sowing, and the seed germination rate should be above 90%.
Soaked after air drying or pelletized before planting(plastic nursery pots manufacturers). Each cell is clearly visible after watering. After the sowing and covering operation is completed, the substrate water holding capacity is more than 1%. The cotyledons are expanded to 2 leaves and the water content is 70% to 75% of the maximum water holding capacity(40 cell plug tray wholesale). 3 leaves 1 heart to commercial seedlings sales, moisture content is the maximum water holding capacity of 65% ~ 70%.
(bulk buy cheap large hydroponic trays online)When planting, it should meet the nutritional needs of eggplant(cell trays). What are the precautions for eggplant seedling seedling technology? The seeding depth of the orifice plate should be greater than 1 cm, and the seeding depth of the 128-hole disk and the 288-hole disk is 0.5-1.0 cm. Ventilation during the day to reduce the relative humidity of the air(40 cell propagation trays wholesale). When the eggplant is sown in quantity, the seedling rate is generally only 60% to 70%.
Therefore, when 60% of the seeds in the seedling tray are arched, the seedling tray can be moved into the nursery greenhouse(black plastic nursery pots). After entering the greenhouse, the daytime temperature should be higher than 25 °C, and the night temperature should be 18-20 °C(36 cell propagation trays wholesale). When the greenhouse night temperature is low, the geothermal line can be used for other temporary heating measures. 2 leaves l heart night temperature can be reduced to about 15 ° C, but not less than 12C.
Most of them are first planted in 288 seedling trays(plastic nursery pots wholesale). When the seedlings grow to 1 or 2 true leaves, they are moved to a 72-well seedling tray. Seedlings with 72-well seedlings, plant height 16-18cm, stem diameter 4.0-4.5mm. Area 110cm2, up to 6-7 true leaves and small flower buds, calendar seedling age 80-85 days, 128-hole seedling tray Seedlings(18 cell propagation trays wholesale), plant height 8-10cm, stem thick 2.5-3.0mm, 4-5 true leaves, leaf area 40-50m, calendar seedling age 70-75 days.
(bulk buy cheap large hydroponic trays online)The performance of the diseased plants is mostly from the bottom up or from one side to the whole plant(plastic nursery pots). The growth of eggplant has a relatively large demand for nutrition. If it is undernourished or lacks certain nutrients, it will lead to various symptoms of eggplant deficiency, lack of magnesium and lack of magnesium(12 cell propagation trays wholesale). Iron is the main cause of eggplant yellow leaves, and some other trace elements can also cause yellowing of eggplant leaves.
