How to sprout Zhonglou seed and blossom in several months

Heavy building is very common in life, its leaf is single, there will be a long stem in the middle, this is its flower. At present, there are people specializing in planting heavy buildings in many places, but at the time of planting, many people are not clear about its budding method and the time of its flowering. Let's take a look at it together.

How to sprout the seeds of Rhizoma thunbergii

1. When the seeds of Rhizoma thunbergii can germinate, they can be carried out according to a certain proportion. Generally, 2500 grains per square meter are scattered on the greenhouse seedling bed, which is 1.2m wide, 20cm high and 30cm wide. After sowing, cover 1:1 humus soil and plant ash, cover the soil about 1.5cm thick, and then cover the soil surface with a layer of pine needles or crushed grass, the thickness is appropriate not to expose the soil, water thoroughly, keep moist. Good management after sowing can start to emerge in May and June, and the emergence rate can reach more than 60%, so it is still very high.

2. Before sowing, the seedbed needs to be weeded and disinfected. The soil of the seedbed should be loose and fertile, and the thickness of the soil layer on the soil surface is 20cm to 30cm. At the same time, apply 1% of the seed weight of carbendazim wettable powder and mix it well, put it in a seedling promoting frame, keep the germination temperature at 18: 22 ℃, check every 15 days, and keep the moisture of the soil (or sand) between 30% and 40% (hold a handful of sand by hand to form a ball, and it is appropriate to disperse after loosening). After the seeds waiting for the heavy building have grown some new roots, they can be sown.

The heavy building blossoms in a few months.

The blooming time of heavy buildings is usually from June to July every year. Pedicel drawn from stem tip, terminal flower; flowers bisexual, sepals lanceolate or long ovate, green, 3.5-150px long; perianth linear and slightly lanceolate, yellow, about 1 2mm of sepals, 2-6mm wide above middle; stamens 8-10, anthers long ltel 37.5px; filaments shorter than anthers, connective protrusions 1-2mm. The flowers of the heavy building are still very beautiful.

The growth habits of heavy buildings

1. Temperature: the resistance of heavy buildings to low temperature environment is still very strong, so the requirement for temperature is not very high. From late February to early March, the temperature of 5 ℃ or even the lowest temperature of 2 ℃ could sprout and grow. When the temperature was 1-2 ℃, the suitable temperature for seed germination, root growth and terminal bud germination was 18 ℃-20 ℃, 20 ℃ for emergence, 16 ℃-20 ℃ for shoot growth and 14 ℃-18 ℃ for underground rhizome growth. We should also pay more attention to the choice of temperature.

2. Lighting: heavy buildings like shade and can not accept too strong sunlight, so shading is also very important when planting. Strong light will wither the leaves, generally seed germination and seedling stage require better shading, a year or two before maturity can appropriately reduce some shade, which is conducive to its growth.

The time for re-building to bloom is usually in summer every year. When seeds germinate, we should first do a good job of soil preparation, and then sow the right amount of seeds, and then plant them at the right time after germination. Chonglou likes to grow in warm places and is not resistant to strong light, so it needs to be shaded.
