Asparagus cultivation methods and precautions

1. Maintenance methods

1. Temperature: Different growth periods have different temperature requirements. It is both cold-resistant and heat-resistant, and its growth is best when the maintenance temperature is 25 degrees. In extremely cold areas, where the temperature is below thirty degrees, it can also survive the winter, but the yield will be reduced.

2. Watering: Its transpiration is relatively small, which means that the water consumption is not large. Therefore, unless it is dry weather, watering is generally not required. Watering in dry weather should also be based on the condition of the soil. Watering is only necessary when the soil is completely dry. Do not water too frequently. Watering once every ten days is most reasonable.

3. Fertilization: The demand for nutrients is different in different periods, so the fertilization method is also different. The seedling stage is when the consumption of nutrients is the greatest. Before planting, you need to mix base fertilizer into the soil. You need to fertilize it once one month after planting, and once more before autumn. For adult plants, it is sufficient to fertilize once every quarter, about four months.

4. Light: It needs a lot of light to grow. Only with sufficient light can the plant grow well. If conditions permit, it is best to have full-day sunlight. If full-day sunlight is not possible, the minimum daily sunlight time must be guaranteed to be five hours.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. The breeding time is generally in autumn or spring. No matter when to breed, you need to dig trenches for planting. Before planting, you need to mix base fertilizer in the soil. After sowing, cover it tightly with soil and then water it thoroughly. Generally, seedlings will emerge in about two weeks.

2. Build a trellis: If the plant grows in a relatively small space, a trellis is needed to help it shape. For example, for asparagus potted plants, a trellis is needed when it grows to 15 centimeters.

3. Problem Diagnosis

1. Odor: Normal asparagus has a grassy smell or no smell. If the asparagus has an odor, it is likely to be contaminated. At this time, do not use inorganic fertilizers and avoid using pesticides, and this situation will be alleviated.

2. Hollow bamboo shoots: The problem of hollow plants is caused by nutritional imbalance. When applying fertilizer, you must reasonably match the fertilizer types, use more phosphorus and potassium fertilizers, and avoid using nitrogen fertilizers.
