Suitable growth environment and climate characteristics for water shield cultivation (water shield seed cultivation technology)

Water shield is a common plant, and it is quite special. This plant grows in water, so it is rarely planted in northern China.

Moreover, water shield has high requirements for temperature and water, and it is difficult to grow in many places. So let's take a look at what techniques are needed to grow water shield? What are some good methods?

① Site selection conditions

Water shield needs sunlight to grow, so when choosing a site, you should choose a sunny place .

When selecting a site, it is also necessary to measure the pH contrast. It is best to choose a place with flowing water, abundant nutrients in the water, and a relatively high depth of silt in the field.

②Sowing method

• Seed sowing method

There are two common methods of sowing water shield: one is sowing with seeds, and the other is cultivation by cuttings.

Because the germination rate of water shield is not high when sown with seeds, it is usually not sown. If you use the seed sowing method, you must choose the seeds in advance, and the seeds you choose must be of good quality .

• Insertion method

Generally, the most commonly used method is cuttings, and the best time to sow is March, April, August and September.

When using the method of cuttings and sowing, the plant density must be adjusted according to the specific conditions of the soil. Generally, the rhizomes of water shield are cut into small sections and inserted directly into the soil.

Normally, areas with more nutrients can use a spacing of 60 cm. For relatively infertile and poor soil , we can use a spacing of 30 cm for planting, which can make the soil more scientific and efficient .

③ Management of water content and water quality

1. Adjustment of water level

In the growth of water shield, water quantity and water quality are very important, which largely determines the yield and quality of the stored vegetable. Only sufficient water can meet the growth needs of water shield.

Usually the depth of water in the field needs to be adjusted according to the seasonal temperature and precipitation. When planting in spring, the most appropriate water depth is 15 cm.

When the seedlings grow, the water level in the field should be appropriately raised, and the water depth should be controlled at about 25 cm to 35 cm. In summer, the amount of water needs to be increased, generally deepening it to 80 cm.

Because the temperature is relatively high in summer, water evaporates more easily. In order for water shield to survive the winter safely, the water depth must be at least 30 cm for normal growth , and it is not easy for water shield to be affected by low temperatures in the spring of the following year.

2. Observation of water quality and fertilizer conditions

The growth of water shield also requires a large amount of fertilizer, but the specific circumstances of fertilization should also be adjusted according to the growth of water shield.

If the leaves of water shield in the field turn yellow or the growth rate becomes slower, you can add appropriate amount of fertilizer.

④Disease treatment

There are two common diseases of water shield: leaf rot and wilt.

Generally, there are not many other reasons for water shield diseases. The most common one is that the water quality is not managed properly. Poor water quality or too much fertilizer may cause diseases.

Therefore, when a disease occurs, the first thing to do is to observe the water quality and then use drugs to treat it according to the specific disease.

Conclusion

The cultivation of pure vegetables is actually not that simple. You must master scientific planting techniques and good planting methods to be able to better grow water shield.
