The Pinellia ternata is a commonly used, large-scale medicinal material harvested all year round. If high-yielding and multi-cultivation cultivation techniques are used, three kinds of harvests can be tried, and wheat, corn, sorghum and fruit trees can also be interplanted. The shade in the dry Pinellia cultivars needs shading, which is beneficial to increase the yield, and the cultivation of white lands has a longer period of dormancy, which is not conducive to the growth of Pinellia ternate. Its cultivation and harvesting processing techniques are as follows:
(1) Site preparation and soil preparation: Cultivation of Pinellia ternata to loose and fertile soil is better, soil preparation is 50 kg of compound fertilizer per acre, or 3,000 kg of thin human excrement, deep tillage, and can be combined with wheat, corn, cotton, and sorghum. Intercropping of high-crop crops of fruit trees.
(B), cultivation time: South of Huanghuai, can be planted throughout the year (winter, spring emergence the following year), Heilongjiang and other places in northeast China and northwest Xinjiang region in April-May planting.
(C), sowing method: usually using tuber propagation, the success rate of 100%, short cycle, quick. The use of Pinellia dormitories can be repeated many times, multiple harvest, that is, in April to close in July, in October to close in October, October in April and close in the next year, the best kind of once a year. The amount of mu for planting depends on the size of the seed block and whether or not the amount of intercropping is determined, generally 30-150 kg. Before planting, dip the seed blocks with 5% grass ash water for 2 hours, or 2% potassium nitrate for 24 hours, or 5% carbendazim for 1000 times. Remove the shade and replant. For example, intercropping with maize, two rows of various corn, finished fonts, five species of Pinellia in the middle, row spacing 18 cm ditch (two rows for each face of the ditch), plant spacing 7 cm, soil compaction after sowing, such as In case of dry weather, it should be watered in time.
(d) Field management;
1, Pinellia root shallow, hi wet afraid of drought, water shortages can easily cause the ground part withered, so pay attention to science watering.
2, timely top-dressing is the main measure to increase production, combined with pouring water and pouring thin human waste.
3. There are small callus buds on the stems of Pinellia sinensis, and the soil can grow into a new pinellia. Soil cultivation is also the main measure for increasing production.
4, Pinellia out of pavilion grow calyx, should go to allow nutrients to transfer to the roots.
5, Pinellia Pests and diseases are not many, mainly tuber rot disease occurs in the water during the rainy season, first from the lower rot, severe stems and leaves withered, so pay attention to drainage. Insects have larvae of hornworms, which eat leaves from July to August, and can be sprayed with 90% of trichlorfon 800 times.
If Pinellia cultivation can strengthen the above several management measures, the output will be greatly improved.
(4) Harvesting and processing:
Before and after the autumnal equinox (September, late), Pinellia was excavated when the leaves were yellow, and the seeds were small, and large processing was used to sell the products. Processing methods: 1, artificial: or bamboo basket with Pinellia and stone in the water, shake, hit the skin, or loaded into the woven bag into the water with the foot, or with water with double income according to the cement floor rub . 2. Machine processing: peel off the skin with a peeling machine. Remove skin, wash away impurities with water, until the appearance of white. When the sun shines, it is best not to stir it by hand, and stir with a wooden stick to avoid skin poisoning and Pinellia discoloration.
