Matters needing attention in the latest planting of Sagittaria

Sagittarius, also known as scissors grass, it is a perennial aquatic herb of Alisma family, planted all over China. The main edible part of arrowhead is its underground bulb, which usually grows in shallow ditches, streams and paddy fields. So what do we need to pay attention to when planting arrowheads? Let's learn together with Xiaobian below.

1. Seed bud treatment

Sagittarius it is mainly the use of seed buds for reproduction and growth, then the selection and treatment of seed buds is also very important. Generally, we will choose the right size, no pests and diseases, fully mature seed buds. Then part of the corms are cut off, soaked in carbendazim, fished out and dried after 15 minutes, and stored through winter. Before sowing, the seeds should be soaked in water for a day or two, and then they can be sown.

2, planting time

Sagittarius also has requirements for planting time, and not all times are suitable for planting sagittarius. Generally speaking, the planting time of arrowhead is from the end of April to the beginning of May every year. At this time, the average temperature can reach more than 15 degrees, so that the emergence rate after sowing will be higher. Sowing time can not be too early or too late, the earliest sowing time can not be earlier than April and a half.

3. Water level adjustment

Water level management is critical for sagittarius cultivation. Although sagittarius is an aquatic plant, its water requirements are of a strict standard. When sowing, the water level of paddy field is generally about two or three centimeters. 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 seedling growth period, the water level should also be maintained at about three centimeters. If the temperature rises above 26 degrees Celsius, then we need to increase the water level reasonably, controlling it at about five to ten centimeters. It is important to note that we need to keep the soil moist in the field no matter what stage it is growing.

4. Topdressing management

Topdressing is to promote the growth of sagittarius, thereby improving the yield and quality of sagittarius. A week or so after planting, topdressing is needed, mainly with decomposed manure. In its whole growth process, we should follow the principle of promotion, control and promotion to carry out topdressing, so as to achieve the best use of nutrients. In the process of fertilizing, nitrogen fertilizer or other fertilizer seeds cannot be applied unilaterally, and attention should be paid to the coordinated use of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer.

5. Disease and pest control

In order to improve the yield and quality of arrowhead, we also need to pay attention to the prevention and control of pests and diseases in the process of planting. The most important diseases are brown spot disease and stripe disease, we can use thiophane combined with chlorothalonil use. The most common pests are aphids, moths, shaving insects, we can use aphidines, dimethoate, beta-cypermethrin to spray kill.

The above are the five most important problems that need to be paid attention to in the process of planting Sagittarius, followed by the density of planting Sagittarius, the trimming of branches and leaves, etc. These are also the problems that we need to pay attention to in the process of planting. If you encounter other problems in the process of planting, you can also ask questions from Xiaobian.
