Cultivation method of Brasenia schreberi

Water shield can also be called horseshoe because its shape is very similar to that of horseshoes. It is an aquatic plant, which mainly appears in the south of the Yangtze River. Because it is grown under certain conditions, it is not available for sale in many places, so it is a relatively precious vegetable, and I believe many friends do not know this kind of talent, so today we are mainly here to learn how to grow water shield. In the future, we can plant according to the specific situation.

1. Land selection and preparation

Water shield needs enough light to grow normally, so we should choose to plant it in the sunny place. the second is that it is easier to survive in places where the soil is acidic, so we need to measure the acidity and alkalinity when selecting the land. and it is best to choose in the area with rich mineral content in living water or water and no pollution, the silt in the field should be about 20 centimeters. When preparing the land, we can use the machine to turn the field, and then raise and reinforce the ridge, which is conducive to water storage and flood prevention, and finally sprinkle an appropriate amount of barnyard manure.

2. Sowing seeds at the right time

There are two ways of sowing, the first is seed sowing, and the second is cutting planting, but the sprouting rate of water shield seeds is special, so seeds are not usually used for sowing, and if seeds are to be used, they need to be carefully selected and then planted after seed treatment, so we still use cutting planting methods most commonly when planting. Water shield can be planted in both spring and autumn, but the best sowing time is in March and April in spring, followed by August and September in autumn.

3. Reasonable close planting

When using cuttings to sow seeds, we need to carry out reasonable close planting according to the fertility of the soil. Usually, we need to cut the stems of water shield into nodes of 10 centimeters respectively, and then insert them vertically into the soil according to a reasonable density. In general, we use the spacing of about 60 to 70 centimeters between rows and 50 centimeters between plants in the soil where nutrients are sufficient. For the more fertile land, we use a row spacing of about 50 centimeters between fish and plants to plant, and for relatively barren soil, we use a spacing of 30 to 40 centimeters. Only in this way can the soil be reasonably and fully utilized.

4. Water and fertilizer management

The water and water quality management of water shield planting is very important. Water shield needs a lot of water to grow. Usually, the water depth in the field needs to be adjusted according to seasonal changes. The water depth is generally about 15 cm when it is first planted in spring. After emergence, the water level can be increased appropriately, and the water depth can be controlled at about 25 to 35, while in summer, we need Ajing water to deepen to about 70 or 80 cm. Because the temperature is relatively high in summer, and in winter, the water depth will be as deep as 30 centimeters, so that water shield can grow normally. The growth liquid of water shield needs a lot of nutrients, but we can only apply fertilizer according to the growth of water shield. If the leaves turn yellow or the growth rate is slow in the field, we can add an appropriate amount of phosphate fertilizer containing trace elements to supplement nutrition.

5. Pest control

The most common diseases of water shield are leaf rot and Fusarium wilt. the main cause of the disease is water pollution, which can be prevented by purifying water quality and using Bordeaux solution. The more common pests are borers, green insects, etc., which can be sprayed with dimethoate milk, followed by a large number of solid snails and flat snails, we can spread tea cakes to kill or determine to kill.
