Witchweed Cultivation Techniques: Late March to early April Is the Suitable Sowing Period
AbstractSoil and fertilizer management: witchweed can only survive by relying on other plants, so natural grassland should be chosen for cultivation. Timely sowing: choose late March to early April for sowing. Transplanting and setting out seedlings: a reasonable planting density is beneficial for the better growth of witchweed in the later stage. Field management: promptly pull out dead seedlings and replace them with healthy young seedlings, weed and topdress on time, and maintain a good living environment.
1. Soil and fertilizer management
Witchweed is a semi-parasitic plant, generally parasitizing the roots of herbaceous plants of the same family. Only by relying on other plants can witchweed carry out photosynthesis and grow normally, so witchweed is not very easy to cultivate artificially.
Choosing the planting site is relatively important. Witchweed is generally widely distributed in areas such as field edges, grassland, and barren hills. Witchweed originally belongs to a category of weeds, so when planting, choosing natural grassland is enough. As long as before planting witchweed, a little fine soil is scattered on the grassland, and then sufficient base fertilizer is applied, witchweed can be planted.
2. Timely sowing
When planting witchweed, it is best to choose around late March to early April, when the temperature is relatively stable. Because witchweed is planted by the method of propagation by sowing, after choosing natural grassland, scatter the witchweed seeds on the surface of the fine soil, and then cover the seeds with a layer of fine soil. The soil temperature is best kept at around 18 to 22 degrees. Under normal procedures, witchweed can emerge in about ten days.
3. Transplanting and setting out seedlings
The growth period of witchweed seedlings is relatively slow, but during the seedling growth period, no special management is needed either. As long as witchweed can maintain normal absorption of water and nutrients, it is enough. When the witchweed seedlings grow to 6 to 8 cm, they can be transplanted and set out. After transplanting, witchweed must maintain a certain density, with row spacing kept at around 30 to 35 cm, and plant spacing kept at around 20 to 25 cm.
4. Field management
About 5 to 7 days after transplanting and planting, observe the growth of witchweed to see whether there are dead seedlings. If dead seedlings are found, promptly pull out the dead seedlings and replace them with healthy witchweed seedlings. The presence of dead seedlings and weak seedlings will affect the normal growth of witchweed. Timely field management can ensure the uniform growth of seedlings.
After the seedlings survive, promptly loosen the soil and weed. If there are too many weeds in the field and they are not cleaned up in time, it will cause uneven nutrient absorption by witchweed. Then water and topdress on time. When the soil dries up, water it to maintain soil moisture. When topdressing, it is best to choose farmyard manure, so that witchweed can have a relatively good living environment and the quality and yield of witchweed can be ensured.
