Key Points and Management Methods for Arrowhead Cultivation

AbstractWhen cultivating arrowhead, try to choose fairly fertile land, or you can prepare base fertilizer yourself. When transplanting seedlings, it is best to choose a relatively hot season and maintain a certain density. During the growth of arrowhead, fertilizer should be applied about three times, and at the final harvest care should also be taken not to damage the corms.

1. Land selection: When choosing a field for arrowhead cultivation, try to choose relatively fertile land, preferably with plenty of sunlight. If the field is not very fertile, you can also use natural fertilizer to make base fertilizer. Each mu of field should preferably not exceed a capacity of 4000 jin, and it should not be too dense, because arrowhead has a fairly large demand for soil nutrients.

2. Transplanting seedlings: The transplanting time for arrowhead is generally from the end of June to early July each year. The soil moisture must be sufficient. In fact, it is quite similar to a paddy field for rice transplanting. The transplanting density is best kept at a spacing of 6 cm, and inserting about 2 cm into the soil is more suitable.

3. Fertilization: During the growth of arrowhead, in addition to doing a good job with base fertilizer, a total of three more fertilizer applications are enough. It is best to use organic compound fertilizer for all applications. The first is applied at the time of transplanting, the second is applied about one month after transplanting, and the last is applied about half a month after the second.

4. Harvest: The harvest time for arrowhead is generally from November to February of the following year. During harvest, great care must be taken, otherwise the corms are easily damaged. Damaged corms are generally very difficult to sell and will also rot quickly during transport, so harvesting is a relatively important step.
