Alisma alismatis is an aquatic plant that can be harvested for many years, but its whole plant is poisonous. It is rarely exposed to alisma alisma in our daily life, but it is planted in most parts of our country. It can be used for heat release, bacteriostasis, diuresis, wetness and urination. The following is the planting method of alisma orientalis brought by the editor, if you want to plant alisma alisma. Then you can take a good look at it.

1. Land selection and preparation

Alisma alismatis has a relatively special place in the selected land and soil preparation, that is, its seedling land and planting land should be selected and prepared separately, and the seedling land will generally be planted in a sticky soil with sufficient sunlight and nutrients, and it is better to have a relatively clear silt soil. On the other hand, the choice of planting site is relatively random, as long as it is close to the water source and the rice planting land with better light. If the seedling land is to be leveled, only 300 jin of fertilizer is needed per mu, while the planting land needs at least 4,000 jin of farm manure per mu, and then deep ploughing is carried out, and finally leveling can be sown.

2. Sowing and raising seedlings

Alisma alismatis usually sows and raises seedlings around June and July every year. Before sowing, we need to soak the seeds in clean water, then soak them with chemicals, remove them and rinse them in about five to ten minutes, mix them in prepared plant ash, and finally spread the seeds evenly on the whole seedbed. Gently press the seeds into the soil with a rake to wait for seedlings to emerge.

3. Seedling stage management

Because alisma alisma is sown in summer, when the temperature is relatively high, and the sun is also relatively large, so we have to carry out heat dissipation treatment, generally around the seedlings will build a shade shed to avoid direct sunlight, the second is to water, used to reduce the temperature of the soil, so that the seedlings grow normally. Secondly, we should pay attention to timely drainage in case of more rainfall, so as not to hurt the seedlings, and then the shade canopy can be removed when the seedlings grow four or five leaves, and reasonable topdressing is carried out according to the growth of alisma alisma seedlings to promote the growth of seedlings.

4. Transplanting and planting

The seedling stage of alisma orientalis is basically about a month, so it can be transplanted in July and August, when the seedlings of alisma alisma have basically grown to about 10 centimeters, and it is best to choose a cloudy day for transplanting, so the survival rate of planting will be higher. In order to increase the yield of alisma to you, we need to plant according to a reasonable density, usually about 9,000 plants per mu. That is, the row spacing is about 25 cm and the plant spacing is about 20 cm.

5. Field management

About two to three days after transplanting, we have to check the alisma seedlings in the field. If there are fallen or dead seedlings, then we should support and replenish the seedlings in time. The water level of the newly planted alisma alismatis field is basically about one centimeter. But in the later stage, we can slowly deepen the secretary in the field, but the highest water level can not exceed 10 centimeters, which is generally the best at about five or six centimeters. In the whole growth process of alisma orientalis, at least three times of topdressing were needed, the first time was mainly irrigated with fecal and urine water, and the second and third times were mainly based on phosphate fertilizer and cake fertilizer, and combined with intertillage. Finally, it should be noted that we should remove the lateral buds and early moss of alisma orientalis properly, which can reduce the consumption of nutrients and promote the growth of tubers.

6. Pest control

The main diseases and insect pests of alisma alismatis are white spot disease, quenching disease, constricted aphid and moth pests. White spot disease and quenching pathogen are diseases caused by fungal infection, and white spot disease can be prevented mainly by seed treatment. and the use of wettable zinc 500 × 800 solution for treatment, while quenching disease can be prevented by controlling the planting density, and treated with Bordeaux solution. As for the pests of alisma, we can use trichlorfon liquid or dimethoate EC to treat them.
