What is the typical per-mu yield of arrowhead?

SummaryIn the first two years, the per-mu yield of arrowhead is around 1600 to 2000 jin, and it is higher in the third year, with the yield reaching about 4000 jin. However, the per-mu yield is closely related to one's own planting techniques, and only with good planting techniques will high yields occur.

The per-mu yield of arrowhead may not be very high in the first two years, basically around 1600 to 2000 jin, and by the third year it begins to stabilize, at about 4000 jin. However, the per-mu yield of arrowhead will have a certain relationship with one's own planting techniques. If the planting techniques are good, then the per-mu yield will be much higher, and if the planting techniques are not done well, then the per-mu yield will also decline somewhat.

How to plant arrowhead

1. Site selection and land preparation.

When planting arrowhead, it is best to choose a place with sufficient sunlight, and the soil should be somewhat fertile. Before planting, the land should first be given a good base fertilizer, and generally farmyard manure is enough.

2. Planting method.

It is best to plant in summer each year, in July or August. When planting, a spacing of about 30 cm is best, plant its seedlings one by one, and then gently fill the edges level with soil, and generally one mu of land can hold about 4200 plants.

3. Planting management.

After planting, arrowhead has a very large demand for fertilizer. When fertilizing, generally farmyard manure or green manure is the main choice. About the thirtieth day after planting, fertilizer should be applied once, and then about one and a half months later, fertilizer should be applied once. As for watering, it needs to be done in a timely manner, and its seedlings must not be allowed to suffer drought, otherwise their survival rate will be affected. Weeds also need to be removed in a timely manner, so as to prevent the other weeds from absorbing its nutrients and making the growth of arrowhead poor.

4. Pest and disease control.

Pest and disease control for arrowhead must be done well, especially in autumn, when the weather begins to cool, as this is the time when some pests and diseases are most likely to appear. The common disease is smut, and the pest is the lotus aphid. When disease occurs, special agents can be chosen for control, such as 70% thiophanate-methyl 1000-fold solution, 50% pirimicarb 2500—3000-fold solution, etc. At ordinary times, management also needs to be strengthened, and reasonable close planting, choosing disease-free buds and seedlings, etc. are all very key. Especially after harvesting arrowhead each year, the residues of some of its diseases should be cleaned up thoroughly, as only in this way can the pathogens be eliminated.
