Last Updated: 2024/11/10, Water shield, also known as lake vegetables, grows in an aquatic environment. Water shield is tasteless and smooth, contains a variety of minerals, vitamins and other nutrients, but also has medicinal value, so it is a precious vegetable. Because the water shield lives in the water, so the later management is the same as its management.

Water shield, also known as lake vegetables, grows in an aquatic environment. Water shield is tasteless and smooth, contains a variety of minerals, vitamins and other nutrients, but also has medicinal value, so it is a precious vegetable. Because water shield lives in water, its later management is different from that of other vegetables. But the main management aspects are more or less the same, but the specific requirements are different. So now let's take a look at how to manage it and what management skills we have.

First, fertilizer and water management

To improve the soil, pond mud and humus can be used to improve the soil, 30 jin of urea per mu, mixed with river sand, 100 jin of rotten straw. After this, there is generally no need for topdressing, if you have to topdressing, just sprinkle dozens of jin of nitrogen fertilizer. Need to grow in the water, can not be without water, and to maintain the 30 cm water layer is best, and then gradually deepen, but not more than 1 meter, not less than 10 cm, so that you can grow well, drought will die. Shallow water in spring and deep water in summer.

Temperature and humidity

Water shield likes temperature and is not cold-resistant. It will grow poorly when it is below 15 degrees, and then it will grow best in the range of 20 to 30 degrees. The growth above 354 degrees will be slower. The air humidity is required to be about 80%. It should not be less than 70%, which is bad for leaf growth. Cool air is required and the water temperature is above 14.

Third, lighting

Like light, when the light is sufficient, it will be beneficial to the growth of leaves, can accumulate nutrients and accelerate reproduction, but the high temperature in midsummer will slow down the growth a little bit. Generally speaking, it needs strong light, can withstand shade, and can grow in shady environment, but it grows well without light.

IV. Disease and pest control

The main pest is root-eating golden flower insect, mainly gnawing on leaves and petals, spraying with 800 times of 90% crystal trichlorfon or 60% imidacloprid 500 solution. There are also aquatic animals such as snail lions and slugs, which are poisoned with soaked snails and bean cakes. It is highly toxic and does not produce drug harm. Or spiroamine, 100 grams per mu is effective. The main disease is leaf rot, first of all, we should often change water, keep the water clean, free of germs, fertilize do not use farm manure, easy to carry germs. After cutting off the diseased branches, disinfect them with lime.

Water shield is mainly planted in the water environment, so the management of water is very important, to maintain a suitable period for the amount of water, and then the temperature and light to meet the requirements of water shield growth. Then pay attention to the prevention and control of diseases and insect pests in the process of growth. The above content provides understanding reference, thank you for reading support.
