Jiangsu Institute of Agricultural Sciences in the region along the Yangtze River has explored its cultivation points since 1997. The flowering rate was stable in 1998. Above 85%, the two-year production practice is summarized below.
Preparation stage: The soil is usually deep-plowed 25-40 cm, stones and weeds are removed, and 1000 kg of organic fertilizer is applied per acre.
The soil can be disinfected with 2 kg of methyl bromide for a week or covered with thiophanate-methyl 1000-fold sprinkling seedbeds. Generally, each shed (3 mx 6 m) can be divided into four beds, each bed is 30 m X 1 m, leaving the aisle in the middle. .
Planting stage: Open the ditch to a depth of 10-15 cm deep, apply 30 kg of ammonium phosphate per acre and 28 kg of potassium sulfate.
Disinfect the bulbs and sterilize them with 500 times carbendazim or chlorothalonil for 20-30 minutes. Weeding before weeding can be used 50% liqueur Ligulon, the amount of 0-1 kg per mu, before the leaves can be manually weeding, after weeding leaves to prevent damage to the root system.
Planting, planting should be deep, generally should be more than 5 cm to prevent lodging, planting density of 50-80 square meters is appropriate.
Management stage: After top-dressing two-leaf stage, O.5% urea can be sprayed on the foliar, 3-4 foliar should be applied with NPK fertilizer, and 0.2% potassium dihydrogen phosphate can be sprayed once every 7-10 days between nursery and anthesis. surface.
Watering, planting until emergence and budding, to keep the soil moist. Water control during flower bud differentiation can promote early flower bud differentiation.
The flowers are collected at the opening of the flower stalk at the bottom of the flower stalk. At this time, the highest sugar content in the stems of the plants is conducive to preservation, and then an organic fertilizer is applied to promote the formation of new bulbs.
Pilling stage: Generally 40-45 days after flowering, excavate new bulbs when half of the aboveground parts begin to yellow. The bulbs should be sterilized with carbendazim and sunned for 10-15 days after unearthing and stored at low temperature.
Bulbs have medicinal value, smashed with honey can cure sore, chopped water to swallow can cure snoring disease.
