Cultivation method of hemerocallis fulva

Abstract

The invention provides a cultivation method of hemerocallis fulva. The cultivation time is at the beginning of March in early spring, the cultivation is performed before germination, the hemerocallis fulva is cultivated and planted in soil with good drainage, deep soil layer, fertile and loose soil, no water accumulation in summer and abundant organic matters, when the hemerocallis fulva is planted, 2-3 kg of decomposed pig and cow dung fertilizer is applied in each square meter of the soil, when the hemerocallis fulva is transplanted, the plant-row spacing needs to kept at 30 cm*40 cm, the top dressing needs to be supplemented for 2-3 times before and during flowering phase, a phosphate-potassium fertilizer is mainly supplemented, 0.2% of potassium dihydrogen phosphate is sprayed for assistance, watering is performed once every other week, and the soil water-holding capacity is kept at 70%-80%. The cultivation method disclosed by the invention has the benefits that the germination rate of the hemerocallis fulva cultivated by the cultivation method disclosed by the invention is 98%, the survival rate is 92.8%, the hemerocallis fulva can normally enter into the repotting stage after 3-month cultivation, and an established large-scale commodity production system is stable and shorter in period, and can meet the large-scale cultivation production needs.

Problems solved by technology

In the past, the seedling stage cultivation was generally carried out in the outdoor field cultivation in areas with a relatively suitable climate. There was no cultivation in the greenhouse, and there were problems of low germination and survival rate.
