Matters needing attention in planting Sagittaria sinensis

Cigu, also known as scissors grass, is a perennial aquatic herb of the family Alismatidae, which is grown all over China. The main edible part of Cigu is its underground bulb, which generally grows in shallow ditches, streams and paddy fields. So what problems do we need to pay attention to when planting Sagittaria? Next, let's study with the editor.

1. Seed bud treatment

Sagittaria mainly uses middle seed buds for reproduction and growth, so the selection and treatment of seed buds are also very important. In general, we will choose medium-sized, disease-free, fully mature buds. Then cut off part of the bulb, soak it with carbendazim, remove it and dry it after 15 minutes for overwintering storage. Before sowing, soak the buds in clean water for a day or two, and then sow the seeds.

2. Planting time

It also has requirements on the time of planting, and not all the time is suitable for planting. Generally speaking, the time of planting is from the end of April to the beginning of May every year, when the average temperature can reach more than 15 degrees, so that the emergence rate will be higher after sowing. The time of sowing should not be too early or too late, and the earliest sowing time should not be earlier than April half.

3. Water level regulation

The water level management of Sagittaria planting is very important. Although it is an aquatic plant, it has a strict standard for water demand. When sowing, the water level in the paddy field is usually about two or three centimeters, and after seven to ten days, we continue to inject new water into the field, and the water level is still controlled at about three centimeters. During the growing period of the seedlings, the water level should also be kept at about 3 centimeters. If the temperature rises above 26 degrees, then we need to reasonably increase the water level at about 5 to 10 centimeters. It is important to note that no matter at any stage of its growth, we need to keep the field soil moist.

4. Topdressing management

Topdressing is to promote the growth of Sagittaria, so as to improve its yield and quality. About a week after planting, topdressing is needed, mainly with rotten manure and water. In the whole process of its growth, we should follow the principles of promotion, control and promotion to topdressing, so as to achieve the best use of nutrients. In the process of fertilization, we should not apply nitrogen fertilizer or other kinds of fertilizer, but should pay attention to the combined use of nitrogen fertilizer, phosphate fertilizer and potash fertilizer.

5. Disease and pest control

In order to improve the yield and quality of Cigu, we also need to pay attention to the prevention and control of diseases and insect pests in the process of planting. The most important diseases are brown spot and spot disease. We can use topiramate combined with chlorothalonil. And the most common pests are aphids, heart borer, shaving insects, we can use aphid dichlorvos, dimethoate, cypermethrin to spray.

These are the five main problems that need to be paid attention to in the process of planting Sagittaria, followed by the density of planting and the trimming of branches and leaves, which are also problems that we need to pay attention to in the process of planting. If you encounter other problems in the planting process, you can also ask the editor for advice.
