Sugen Flower Base talks about its maintenance

0010010 nbsp; 0010010 nbsp;The main maintenance of perennial root flowers is in winter, because winter is a dormant period, in order to grow and germinate well in the coming year, the roots need to be buried in the soil.

Although the perennial flowers at the perennial flower base can obtain the required water from natural rainfall, due to the unevenness of natural rainfall, the growth needs of perennial flowers cannot often be achieved. It should be noted that the dry and rainy season has a great influence on the normal growth of perennial flowers, so irrigation is an important part of the maintenance and management of perennial flowers.

Irrigation water is preferably soft water, reducing the use of hard water, the need to use river water, pond water and lake water. The temperature of well water is often quite different from the surface temperature. Generally, it should be extracted and stored for a period of time before use; industrial wastewater is often polluted, harmful to plants, and cannot be used.

Fertilize

The nutrient management of perennial flowers at the perennial flower base can refer to green space maintenance. It should be emphasized that perennial flowers are more sensitive to fertilizers than woody plants. There are also differences between perennial flowers and lawns. If soil nutrients are insufficient, it will seriously affect flowering and landscape effects.

base fertilizer

Mainly organic fertilizers, commonly used are manure, compost, cake fertilizer, bone meal, animal dry manure, etc. Organic fertilizer plays an important role in improving the physical properties of the soil. Usually the amount of composting perennial flowers is1 ～ 2. 2 5kg / m 2, stable manure and compost are often turned into the soil during land preparation, cake fertilizer, bone meal and animal dung can be applied to the planting ditch or Fix the bottom of the planting hole.

top dressing

Top dressing is the deficiency of supplementing basic fertilizer to meet the needs of different growth and development stages of perennial flowers. Commonly used fertilizers are compound fertilizers, such as peat soil, cake fertilizer (water), etc. During the period of strong growth and early flowering, foliar spraying can be carried out. Commonly used fertilizers include urea, potassium dihydrogen phosphate, and superphosphate. The spraying concentration should generally not exceed0. 1% ～ 0. 3%.

The topdressing of the perennial roots of the perennial roots in the seedling base is mainly nitrogen fertilizer, the main purpose is to promote the growth of their stems and leaves; the growth period should be based on the application of phosphorus and potassium fertilizers. For some perennial (bulb) flowers with a longer flowering period, such as canna and dahlia, topdressing should also be properly given during the flowering period to supplement the nutrients required for continuous flowering and it is easy to increase the flowering period.
