How much do Heterophylla pseudostellaria seeds cost? Detailed planting methods
Heterophylla pseudostellaria, also known as haier ginseng, shuangpiqi, four-leaf ginseng, etc., is a perennial herbaceous plant of the genus Pseudostellaria in the carnation family. It likes to grow in warm and humid environments and is distributed in Liaoning, Hebei, Shandong, Anhui, Jiangsu and other places. Its roots are used as medicine and have effects such as strengthening the spleen and replenishing qi, nourishing blood and promoting fluid production. Let us take a look at Heterophylla pseudostellaria seed prices and planting methods together below!
How much is Heterophylla pseudostellaria seed per jin?
The price of Heterophylla pseudostellaria seeds is about 40-50 yuan per jin, but prices vary greatly depending on seed quality, variety, place of origin and market. Heterophylla pseudostellaria propagation methods are divided into two types: seed propagation and rhizome propagation. Because the seeds mature unevenly and the seeds fall off naturally after the capsule splits, harvesting is not easy. Generally, after harvest, seedlings are cultivated on the spot, and large-scale production mostly uses rhizome propagation. At the same time, Heterophylla pseudostellaria is susceptible to mosaic virus disease, which has a very large impact on yield after onset, so it is best to choose Heterophylla pseudostellaria varieties with high resistance to mosaic virus.
Sowing methods for Heterophylla pseudostellaria
1. Soil selection: For Heterophylla pseudostellaria planting, choose sandy loam soil with good soil fertility and irrigation conditions. Clay soil, waterlogged low-lying land, and plots whose previous crop was tobacco are not suitable for cultivation.
2. Apply sufficient base fertilizer: Before plowing for Heterophylla pseudostellaria, evenly spread 5-6 cubic meters of high-quality farmyard manure, 50 kg of ammonium bicarbonate, and 50 kg of nitrogen, phosphorus and potassium compound fertilizer per mu.
3. Level the bed surface: After fertilizing the Heterophylla pseudostellaria planting land, plow to a depth of 20 cm, level it and then rake it fine. With a bed spacing of 180-200 cm, make raised beds with a height of 10-15 cm and a surface width of 130-140 cm. After leveling the bed surface, it is ready.
4. Sow at the right time: For Heterophylla pseudostellaria, in October-November, evenly broadcast the seeds on the bed surface, then take soil from another bed to cover them with a thickness of 1 cm. For both drilling and broadcasting, the seeding rate is about 5 jin per mu.
5. Post-sowing management: After sowing Heterophylla pseudostellaria, cover the bed surface with 8-10 cm thick wheat straw and cover it with a nylon net. In early March of the following year, remove part of the wheat straw, but still leave a small amount of wheat straw (just enough to tightly cover the bed surface).
Planting methods for Heterophylla pseudostellaria
1. Seedling preparation: The ginseng seedlings (tuberous roots) cultivated for Heterophylla pseudostellaria have 2 sources: one is the seedling field, and the other is the main field. For both sources of ginseng seedlings, about 1 mu is expanded to plant about 10 mu. In September-October, after digging out the ginseng, pick out diseased and weak roots and set them aside for planting.
2. Plant at the right time: In September-October, place Heterophylla pseudostellaria seedlings flat in the ditch end to end. Place 1 large seedling, 2 medium seedlings, or 3-4 small seedlings, then cover and level the bed surface. Use about 50 kg of seed roots per mu.
3. Weeding and topdressing: After the Heterophylla pseudostellaria seedlings emerge completely, do 1 shallow loosening of the soil, and combine it with weeding to apply 1 topdressing of thin human and livestock manure water to promote strong seedling growth. After that, pull out weeds as soon as they appear, keep the field free of weeds, and stop weeding in early May.
4. Hill up soil at the right time: After Heterophylla pseudostellaria emerges in early spring, cover the bed surface with soil from the cleared ditches, scatter it beside the plants, and carry out hilling, which is beneficial to root growth and development, but the thickness must be below 1.5 cm, otherwise there will be fewer roots and yield will be affected.
5. Drainage and irrigation: Heterophylla pseudostellaria is afraid of waterlogging. During the rainy season and after heavy rain, clear the ditches and drain water in time. But it is also afraid of drought. During severe drought, attention should be paid to watering, often keeping the soil moist to promote root development.
6. Pest and disease control: Heterophylla pseudostellaria diseases include black spot, leaf mold and viral disease, which can be controlled with 50% mancozeb 500-fold solution and phosethyl-Al 500-fold solution. For insect pests, 1-1.5 kg of phorate should be broadcast per mu at planting time.
7. Harvest at the right time: When more than half of the leaves in the Heterophylla pseudostellaria field have turned yellow and withered, it can be dug for harvest. Before digging, sweep up the seeds, mix them with wet sand and store them in a cool place. After harvesting commercial fresh ginseng, dry it in the sun in time. When half dry, rub off the fibrous roots, continue drying until completely dry, and keep for sale.
