Medicinal planting techniques in dry and semi-summer

The dry Pinellia is a perennial herb of the Southern Star Family. The whole plant is 15-30 cm in height. The medicinal underground bulbous stem has the effects of dampness, phlegm, and down-regulation and vomiting. The original wild was on hillside or damp grass and forest.

First, site preparation: mainly sandy or semi-sand soil, followed by other soils, should have good drainage conditions and watering conditions. It is not appropriate to plant the land where the sand is too sticky. In the field operation, the centipede must be 1.5 meters wide and not too wide. Before and after the "May Day", two rows of corn were planted on the loquat to facilitate the shading of the Pinellia terrine. The planting can be done in addition to the fruit trees, and grows well. Regardless of whether the spring planting or the autumn plant should be well-prepared in advance, the base fertilizer must be applied to the base fertilizer. The cultivated land should not be too deep, because this species is only 5-7 cm deep, and harvesting is easy.

Second, sowing: According to spacing 15-20 cm, open 3-4 cm deep ditch, the seed ball evenly sprinkled in the ditch, plant spacing 2-6 cm (small dense, large thin), complex soil 1-2 centimeters after the flattening, drought can be watered, the temperature of 18-20 degrees, generally 12-15 days successive emergence.

Third, field management: Pinellia two or three times a year the emergence and down seedling phenomenon, down a few days after the seedlings also re-emerged new seedlings, which is a normal breeding phenomenon. If any grass is removed during the seedling stage, do not use weeds to prevent weeding. If the land is drowning, it can be watered in time for seedling emergence. The seedlings are topdressed with nitrogen, phosphorus and potassium fertilizers, with 20-25 kg of mu, taking care not to stick to the foliage. Tian Yan's corn is managed as usual, and forest trees are also managed according to the rules, which is not harmful to Pinellia. Pay attention to drainage when there is too much rain, and do not accumulate water for a long time. When there are flowers, they can be cut off, so that the nutrients can be concentrated in the underground tubers, which will increase production.

Herbicides can be used after the seedlings are poured down in the Pinellia trifoliate or Kekuile. The dosage is less than that of the herbicide. A few days later, it is sprayed once more and sprayed before the evening afternoon. This works well.

Fourth, harvesting and processing: According to local conditions, late autumn or early spring shaved, remove the dirt, wash the skin, drying is the medicine.

Note: Pinellia is toxic and must not be eaten. After touching or processing, wash hands with soap.
