How to Grow Cynanchum hancockianum? Detailed Planting Methods and Techniques

The scientific name of Cynanchum hancockianum is Cynanchum hancockianum, and it is a medicinal plant that can treat various joint pains. So how do you grow Cynanchum hancockianum?

1. Site selection

Choose land with loose soil and open terrain for planting, and carry out land preparation before planting.

The specific process of land preparation is:

1. Apply 3000-5000 kg of decomposed pig and cattle manure or residue fertilizer (including turf compost) per 667 sq m, or 30-50 kg of superphosphate;

2. Cynanchum hancockianum is a shallow-rooted plant, so fertilizer generally does not need to be applied deeply. It is usually applied only after the second plowing, so that the fertilizer is mixed evenly with the soil;

3. After the land is leveled, open furrows and make beds. The size of the seedling bed should be determined according to the terrain and should be conducive to drainage and irrigation, field operations, and improving land utilization.

2. Sowing

Sow according to a reasonable density and depth, and cover with film after sowing is completed.

The sowing methods are seed stem seedling transplanting and seed propagation, among which:

1. Seed stem seedling transplanting

A rhizome seedling refers to a seedling stem that emerges from the ground from the tip of a rhizome. In late March or early April, in a plot reserved for growing Cynanchum hancockianum, select thick seedling stems and cut off 2 or 3 nodes of rhizome from below their root zone, with a little native soil attached. The tip of the seedling stem is especially tender and weak, so it should be pinched off, leaving only the upper 3 or 4 pairs of leaves to reduce evaporation. The planting row spacing is the same as that of the direct seed sowing method. After rooting, water thoroughly to firm the roots and increase the survival rate.

2. Seed propagation

From late March to early April, on prepared land, open holes and sow directly. The plant and row spacing can be determined according to the fertility of the land: 30 cm × 40 cm for fertile land, and 30 cm × 30 cm for medium land. The holes should be 3 cm deep. The seeds should first be soaked in warm water to promote germination, and then sown, with 3-4 seeds per hole. The covering soil should not be too thick; the seeds should just be hidden from view. After covering with soil, cover with straw, preferably plastic film, to increase soil temperature, maintain moisture, and promote seed emergence. To extend the growth period of seed-grown seedlings, seedling raising and transplanting can be used, that is, sowing in a heated bed in mid-to-late January, and in early-to-mid April, when the seedlings reach about 6 cm, transplant them into the field beds.

3. Field management

After the seeds germinate and grow into suitable seedlings, they can be transplanted, and after transplanting, appropriate field management is all that is needed.

1. Fertilization

The fertilizer can be superphosphate or compound fertilizer, or cake fertilizer, 35-60 kg per 667 sq m. After fertilizing, cover with soil to a thickness of about 3 cm. For the second application, only earthing up is needed.

After seed-grown seedlings grow their 3rd pair of true leaves, or after rhizome seedlings are transplanted and the lateral buds sprouting at the tip of the seedling stem grow their 3rd pair of leaves, topdressing should be carried out once every half month until early August. The fertilizer should mainly be urea, and decomposed human manure and urine can also be used (it needs to be properly diluted). After early August, earthing up and topdressing should be carried out 2 times. One is in mid-August, and the other is in early September.

2. Watering

Cynanchum hancockianum likes moisture and is not drought-tolerant, so whenever there is drought, irrigation must be carried out to keep the field moist. If there is prolonged rain without clearing, drainage should be carried out in time.

3. Weeding

After the seeds emerge, remove the straw or plastic film, and do a good job of thinning and filling in seedlings. Seedlings, especially seedling-grown plants, grow slowly at first, and weeds are most likely to grow, so loosen the soil and weed in time to promote seedling growth. After August, the rhizomes spread in all directions, so soil loosening should be stopped; if there are weeds, they can be pulled out by hand.

In addition, pest and disease control is also needed, so as to ensure the normal growth of Cynanchum hancockianum.
