Technical management of planting heavy buildings

Zhonglou is a kind of plant of Liliaceae, which is commonly used as medicinal material, and the common species is Yunnan Zhonglou or seven leaves and one flower. Rhizoma thunbergii has some medicinal effects. The planting of heavy buildings is suitable for planting in the southwest, and there are certain requirements for the growth environment, so planting management also pays attention to these aspects. Let's learn about the planting content of Zhonglou now.

1. Seedling stage

The heavy building generally needs to be transplanted after raising seedlings, use river sand stratification to promote germination before sowing, sow after germination, sow pay attention to moisturizing, cover wet fine soil, and pay attention to moisturizing before seedlings grow true leaves. Can not fertilize, the root system is not perfect. After growing true leaves, you can spray less water and fertilize water properly. It can be transplanted as soon as it reaches the growth height. However, transplanting should be appropriate, too small to hurt the root, too big will also hurt the root.

2. Transplanting period

Transplant, pull out from the soil, inevitably hurt the root, but the root injury as far as possible, can be more watering after pulling out, or with some soil planting, it is not easy to hurt the root. Transplanting will have a slow seedling stage, waiting for the root growth relaxation period, when watering in the early stage and topdressing in the later stage. Nitrogen, phosphorus and potassium need to be used together. It is mainly a large number of promoting roots.

3. Growth period

The temperature and moisture of the heavy building growth period need to be controlled, for example, the soil moisture should be about 40%, the surface layer of the soil is about 2 cm but moist, and the temperature is at least above 12 degrees. Low temperature is easily affected, but there is generally no low temperature when heavy buildings grow. Drip irrigation or sprinkler irrigation can always moisturize. The general temperature of the open field planting season is fine, from spring to autumn. Some farm manure can be applied during the growing period.

4. Flowering and expansion period

Flowering is generally from May to July, flowering in the relatively high temperature season, when the temperature should be more than 35 degrees, will be affected. Moisture can be reduced appropriately during flowering, but if the temperature is extremely high and the ground is dry, watering is needed. Fertilization should be prepared before this, farm manure as well as nitrogen, phosphorus and potassium fertilizer should be applied. The heavy building is the characteristic of blooming and expanding the rhizome at the same time, so we should pay attention to the supply of nutrition and balance the growth relationship between the two.

Chonglou is a kind of perennial medicinal plant with several species, which has the characteristics of flowering and rhizome expansion at the same time. Therefore, it is necessary to determine the planting technical management work that should be done during the growth period according to these characteristics. Or something else.
