How to plant Pinellia ternata?

After the land is selected, from June 5438+00 to June 5438+0 1, the land will be deeply dug for about 20 cm, and the gravel and weeds will be removed to make it weathered and mature. Pinellia ternata has a short growth period, and base fertilizer plays an important role in it. Combined with soil preparation, 2000 kg of stable manure or compost and 50 kg of calcium superphosphate were applied every 667 m2, and turned into soil as base fertilizer. Plow it again before sowing, then rake it flat, and increase the width of the border 1.3 m, and the width of the border ditch is 40 cm. Or after shallow tillage, it is made into a flat ridge with a width of 0.8 ~ 1.2 m, and the ridge width and height are 30 cm and 15 cm respectively. It is necessary to level the ridge of the field in a down-to-earth manner, so that spring sowing can accelerate germination and plastic film mulching cultivation can be carried out at seedling stage. Accelerating germination and plastic film mulching not only make Pinellia ternate germinate early, increase the growth period by more than 20 days, but also keep loose state during soil preparation, promote root growth, make Pinellia ternate root thick and long, develop root system, and enhance the ability of drought resistance and seedling lodging prevention.
