The minimum temperature is above 6 °C, and it is stable after 5-7 days of colonization(square nursery pots). Planting density varies according to seasons and varieties and pruning methods. The single dry pruning can be properly densely planted, the row spacing is 50 cm, the plant spacing is 30-40 cm, and the double dry pruning should be appropriately thin(gallon nursery pots). Early-maturing varieties can be densely planted, and medium- and late-maturing varieties are slightly planted.(4 inch square nursery pots in bulk online)
It can be watered by hole application or dissolved water(seed starter trays). According to the actual dry and wet conditions of the soil, the relative humidity during the day does not exceed 60%, and the nighttime is not higher than 80%. After pouring the bottom water at the time of planting, water the seedling water for another 3 to 5 days, and then start to water the water when the first ear grows to the size of the walnut(cell trays). After 10 to 15 days, water is poured to ensure the soil is evenly moist.
(4 inch square nursery pots in bulk online)The secondary top dressing applies 20 kg of compound fertilizer per 667 square meters during the second to third ear fruit expansion period(wholesale greenhouse pots). Minimize ventilation within one week after planting to promote slow seedlings, but when the temperature exceeds 30 °C, it should be ventilated and cooled in time. When fruit thinning, the fruit has 3 to 4 ears per ear, and the middle fruit has 4 to 6 ears per ear(gallon plant pot). When the fruit is half red, it can be harvested in batches. It should be harvested with sowing or wet sand.
Or special fertilizer for nursery, while soaking seeds for 20 minutes, especially in the later stages of birth, see dry and wet, proper irrigation(greenhouse supplies pots). When the plant grows to more than 30 cm, it will be framed in time to bind the tomato stem to the stent. According to the growth of the plant, the topping should be carried out in time, and two leaves should be left on the last ear when topping. When the leaves of the plants gradually turn yellow(plug trays), the onions have stopped growing and expanding, that is, they should be harvested in time.
(4 inch square nursery pots in bulk online)Firstly, the roots of the mother plants are excavated, and the high-density, well-drained shovel is used to make the raking bed(plastic grow pots), and the 15-cm-thick river sand is laid. The river sand is disinfected with 0.5% potassium permanganate. The root insertion method is to use the roots of the peony in autumn to cut the roots, cut into 5~10 cm root segments, and insert them into deep-ditched and flat wells(propagation tray). Another breeding method is sowing and breeding: when the peony seeds mature in August, the fruit is cracked.
The whole branch should adopt the single-stalk pruning method(plastic plant trays wholesale). The sowing area should be leeward to the sun, and the sandy soil rich in humus is good. If the roots of the ramets are large (with 3 to 5 buds), the spring shoots will sprout out of the buds of the pots, and they will be introduced into the pots with a diameter of 15-20 cm. The potting soil is moist and can be rooted in the summer(greenhouse trays). This technique is also called cloning technology, which achieves the purpose of rapid reproduction and has wide application value.(4 inch square nursery pots in bulk online)
In the cold season, the application of nitrogen fertilizer should be controlled during the growing season(wholesale nursery pots). Fertilization should pay attention to timely drainage of nitrogen, phosphorus and potassium in combination with bulbs to avoid long-term water accumulation. Before the onset, the following agents were used: 72% agricultural streptomycin 4000 times solution, 405 Fuxing emulsifiable oil 8000 times solution alternately sprayed(36 cell trays bulk). Remove the onion from the harvest and do not damage the onion for storage and transportation.
