The latest planting method of water shield

Brasenia schreberi can also be called horseshoe mainly because its shape is very similar to horseshoe. It is an aquatic plant, mainly appearing in Jiangnan area. Because it has certain conditions when planted, many places do not have to sell it, so it is a kind of precious vegetable. Moreover, I believe many friends do not know this kind of talent. So today we mainly come to learn the planting method of Brasenia schreberi. Later, we can plant it according to specific conditions.

1. Land selection and preparation

Brasenia schreberi needs sufficient light to grow normally, so we should choose to plant it in a sunny place, followed by it is easier to survive in acidic soil, so we need to measure the pH value when selecting the land, and it is better to choose in a zone rich in minerals and no pollution in running water or water. The silt in the field is preferably about 20 cm. When preparing the soil, we can use machines to turn the fields, and then raise and strengthen the ridges, which is conducive to water storage and flood prevention, and finally sprinkle appropriate amount of manure.

2. Timely sowing

There are two ways of sowing, the first is seed sowing, the second is cutting planting, but the germination rate of Brasenia schreberi seeds is special, so seeds are usually not used for sowing. If seeds are used, they need to be carefully selected, and then planted after seed treatment. Therefore, the most commonly used planting method is cutting planting. Brasenia schreberi can be planted in spring and autumn, but the best sowing time is March and April in spring, followed by August and September in autumn.

3. Reasonable close planting

When using cuttage sowing, we need to carry out reasonable close planting according to the fertility of the soil. Usually, we need to cut the stems of Brasenia schreberi into sections of 10 cm, and then insert them vertically into the soil according to reasonable density. Generally, we plant the land with sufficient nutrients at intervals of about 60 to 70 cm between rows and 50 cm between plants. For fertile land, we plant it with a row spacing of about 50 cm. For relatively poor soil, we plant it with a spacing of 30 to 40 cm. Only in this way can the soil be reasonably and fully utilized.

4. Water and fertilizer management

Water and water quality management of Brasenia schreberi planting is very important. Brasenia schreberi 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 seedling emergence, the water level can be increased appropriately. The water depth is controlled at about 25 to 35 cm. In summer, we need to deepen the still water to about 70 cm, because the temperature in summer is relatively high. In winter, the water depth should be 30 cm, so that Brasenia schreberi can grow normally. The growth solution of Brasenia schreberi needs a lot of nutrients, but we can only fertilize according to the growth of Brasenia schreberi. If the leaves are yellow or the growth speed is slow in the field, we can add appropriate amount of phosphorus fertilizer containing trace elements to supplement nutrients.

5, pest control

The most common diseases of Brasenia schreberi are leaf rot and blight, which are mainly caused by water pollution. We can control them by purifying water quality and using Bordeaux mixture. The more common pests are borers, green insects, etc., which can be sprayed with dimethoate milk, followed by a large number of conch snails and flat snails. We can spread tea cakes to poison or identify them for killing.
