Cultivation techniques of Pinellia ternata with three crops in a year

Pinellia ternata is a common large quantity of traditional Chinese medicine harvested all the year round. it has wide adaptability, easy cultivation and simple management. If the high-yield and multi-cropping cultivation technique is adopted, three kinds and three harvests in one year can be realized, and the benefit is extremely remarkable. Especially interplanting with wheat, corn, sorghum and other crops, the economic benefit is higher.

In this paper, the cultivation, harvest and processing techniques of Pinellia ternata are introduced as follows:

I. selection of land and land preparation

It is better to plant Pinellia ternata with loose and fertile soil. When preparing the soil, 3000Mu of miscellaneous fertilizer is applied, 30kg of phosphate fertilizer is applied, 100kg of plant ash is applied, and ammonium hydrogen phosphate is avoided. Deep ploughing fine rake, 1.3 meters wide, 0.17 meters high, 0.3 meters wide, the ditch can be intercropped with wheat, corn, sorghum or kenaf and other long-stalk crops.

2. Sowing method

Tubers are usually used to propagate three kinds of three crops a year, that is, April, July, July, October, and April of the following year. The number of seed blocks per mu varies with the size, and the general seed requirement per mu is more than 40 kg. When planting, ditches can be opened with a row spacing of 18 cm. Select white, disease-free tubers sown according to the plant distance of 10 Mel 15 cm, compaction the soil, in case of dry weather, water along the ditch, and then sow the soil.

III. Field management

Mainly do a good job of weeding and cultivating the soil, hoe when you see the grass, first shallow and then deep. After growing for about one and a half months, there are buds on the petiole and the soil begins to be cultivated. Combined with soil cultivation, phosphate fertilizer and plant ash or potassium dihydrogen phosphate can be applied. If the soil is not cultivated, the pearl antler will be exposed and new beads will not grow; in case of drought, it should be frequently watered with small water and ploughed to cultivate the soil after pouring. In the late growth stage of Pinellia ternata, burdock should be cut off so as not to consume nutrients and affect the growth of tubers.

IV. Disease and pest control

To prevent and cure virus diseases, you can spray 1500 times of Zhanling liquid, control leaf spot and root rot, spray and irrigate 1800 times of carbendazim wettable powder or 1800 times of agricultural antibiotic 120 water agent. 1000 times of phoxim can be sprayed to control thrips and diamondback moth larvae. Fifth, when harvesting, processing and harvesting, ploughing can be done with ploughing, careful picking, large ones being used as medicine, and small ones being used as seeds. The medicine is first piled up indoor for 5 days, making it sweaty and easy to desquamate. Then put it in a sack or woven bag, put it on a board or slate, rub it with water, peel it, then pour it into a sieve and immerse it in water, bleach off the dregs and sell it directly to the local medicine purchasing department.
