Plastic Greenhouse 10x20 Plant Growing Trays


From the radish seedlings grow 2 to 3 true leaves from the beginning of the harvest to about half a month before harvest(plastic nursery pots), spray boron fertilizer once every 20 days, 150 grams of borax or 100 grams of boric acid per acre, first dissolved with a small amount of warm water(128 cell plastic propagation tray wholesale price), It is sprayed evenly with water of 60-75 kg, and the spraying time is suitable for evening.


The fertilization plots with insufficient fertility should be closely followed by topdressing(cell trays), and the application of diammonium 15~20 kg per mu can achieve obvious yield increase. If there is a trend of prosperous(162 cell seed starting trays), the initial flowering period is 15% paclobutrazol 40~50g plus 50kg of water for foliar spraying or 15ml with 25mg of water to spray 50kg of water.(plastic greenhouse 10x20 plant growing trays)


From the flowering to the bulging stage, it is the peak period of fertilizer demand(105 cell seedling trays wholesale). There are several methods for topdressing, such as application, application, application, spraying, filling with water and top dressing. When planting, use 17% boric acid 300g or 11% borax 500g, mix it into 5-10kg of dry fine soil(15 cell trays bulk), mix well and then sieve, then apply it as a base fertilizer into the seed ditch or seed hole.


The combination of quick-acting fertilizer and slow-acting fertilizer can be adjusted to each other(plastic nursery pots wholesale), and sufficient nutrients can be supplied for a long time. The boron fertilizer is mixed with 3 to 5 kg of fine soil and 300 g of boric acid per acre or 500 g of borax per acre, and stirred into a thin paste(21 cell trays bulk). The radish seeds can also be mixed into the dry fine soil mixed with boron fertilizer, and thoroughly mixed and sprinkled into the seed ditch and the seed hole.


(plastic greenhouse 10x20 plant growing trays)The soil containing the boron fertilizer is adhered to the surface of the seed by hand to make a seed coat(plastic nursery pots manufacturers), and the seed can be separated from the seed to be used for seeding. Like other plants, orchids must meet the needs of nitrogen, phosphorus and potassium nutrients, but trace elements such as calcium(32 cell trays bulk), iron, zinc, magnesium, copper, boron and molybdenum are also essential.


Therefore, forage seed fertilizer is often used for fertilization of orchid leaf surface fertilizer(wholesale nursery pots), and then nitrogen contains urea, ammonium sulfate, ammonium nitrate, phosphorus containing superphosphate, potassium phosphate, potassium dihydrogen phosphate, potassium containing potassium nitrate, Potassium chloride(200 cell seed starting trays), calcium containing superphosphate, iron containing ferrous sulfate.(plastic greenhouse 10x20 plant growing trays)


Pour radish seeds and some dry fine soil, apply 30-70 grams per mu when applying trace elements(black plastic nursery pots). First, there are zinc sulfate containing zinc sulfate, magnesium containing magnesium sulfate, copper containing copper sulfate, boron containing borax, boric acid, and molybdenum containing molybdic acid(50 cell trays bulk). Fertilization of orchid leaf surface must be carried out according to a certain ratio to ensure that it has good fertilizer efficiency and no fat damage. 


(plastic greenhouse 10x20 plant growing trays)But now it is better to use the decomposed manure or manure(128 cell seedling trays wholesale). The concentration of spray fertilizer varies with different fertilizers. Generally, it is controlled: urea 0.2%, potassium dihydrogen phosphate 0.3%, potassium sulfate, potassium nitrate compound fertilizer 0.1%, superphosphate 0.5%, magnesium sulfate 0.5%, ferrous sulfate 0.5 %(72 cell trays bulk), zinc sulfate 0.1%, copper sulfate 0.2%, borax, boric acid 0.3%, molybdic acid 0.1%.
