Seed price and planting method of Euryale seed

Euryale seed, also known as chicken head rice, chicken head fruit, wild goose beak seed, etc., is the dry and mature seed of Euryale Euryale of Nymphaeaceae. It is produced in all parts of China. It is rich in starch for edible, wine-making and non-staple food production. It is used as medicine for beneficial effects of kidney consolidation, tonifying spleen and diarrhea, dehumidification and belt stoppage. Let's take a look at Euryale seed price and planting method.

How much is the Euryale seed per jin?

The price of Euryale seeds is about 20-30 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of the seeds. Euryale seeds are wild in lakes and marshes in the north and south of China, and cultivated in Jiangsu and Zhejiang provinces. Southern Euryale is produced in Taihu Lake area of Jiangsu Province, which is of good quality, but its adaptability is not as good as that of northern thickening. Northern Euryale is produced in Hongze Lake area, which is wild or semi-wild, with poor quality but strong adaptability.

The planting method of Euryale seed

1. Seed soaking and germination: in the middle and lower reaches of the Yangtze River, the seeds were washed and soaked in clean water at the beginning of April. The depth of the water was to submerge the seeds. The water was often changed, and the sun and night cover were kept at 20: 25 ℃ during the day and more than 16 ℃ at night. Most of the seeds could be sown after 7 to 10 days of germination.

2. Sowing and raising seedlings: dig a 2-meter square and 20-centimeter deep seedling pond 5-7 days before sowing, remove filamentous algae, duckweed, weeds and other pests, flatten the sediment, irrigate about 10 centimeters, and so on, spread the germinated seeds evenly near the water surface after the mud water is clarified.

3. Pseudo-planting of transplanting seedlings: about 1 month after sowing, when Euryale seedlings have 2 or 3 young leaves, they can be transferred and planted. 40 square meters of seedlings are needed for 1 kg of seeds, and weeds and pests are removed in the seedling fields. Irrigation is about 15 cm, leveling the soil, not being too fertile and transplanting too deep.

4. Real-time colonization: the round shield-shaped leaves of Euryale seedlings can be planted when the diameter of the shield-shaped leaves is 250cm in mid-late June. Before planting, the holes are about 125cm / mu. When opening the holes, the weeds in the holes should be removed and appropriate base fertilizer should be applied. After 1 to 2 days, the plants can be settled when the mud water in the hole is clarified.

Planting management of Euryale seed

1. Check seedlings and replenish seedlings: Euryale seedlings can turn green after planting for 7 days. After survival, check seedlings for at least 1 or 2 times to ensure the whole seedling. Check if there is mud in the heart leaves of Euryale seedlings that do not grow well. If so, they should be removed.

2. Water layer management: when Euryale seedlings are planted, the water layer should not be shallower than 30 cm. After survival, the water layer can be gradually increased to 50 cm, and the maximum depth should not exceed 1.2 cm. The suitable depth of thickening water in shallow paddy field is 30 cm to 50 cm.

3. According to the weed growth, weeding in the field can be combined with weeding, that is, the soil at the edge of the hole should be pushed into the hole one by one, and the plant should not be damaged during operation. Topdressing can be combined with weeding.

4. Reasonable topdressing: Euryale seedlings generally use deep application of fertilizer balls (before row closure) or external root spraying (after row closure). Fertilizer balls are retted from soil and fertilizer, adding 50 kg of mature manure, 20 kg of urea, 20 kg of superphosphate and 10 kg of potassium chloride per 100 kg of fine soil.

5. Splash water to cool down: when planting Euryale seeds, you should often go to the field in the early morning and sprinkle cold water on the leaves to reduce the leaf temperature and promote flowering and fruiting. When splashing water, you must pour clear water, not muddy mud water on Euryale leaves, so as not to affect photosynthesis and cause rotten leaves.

6. Harvest and processing: Euryale can be harvested in the same year, and can be harvested when the pericarp is reddish brown from September to October. If the planting area is small and the manpower is sufficient, it can be harvested along with ripening. The harvested fruit hammers the prickly pericarp with sticks and other things, and the seeds can be dried in the sun.

Disease and pest control of Euryale seed

1. Leaf spot

[symptoms] at the beginning of the disease, there are many round disease spots on the leaf edge, which are dark green at first, and then turn dark brown, sometimes with wheel lines, which are very easy to rot and perforate. when the disease is serious, the disease spot can be connected with synthetic tablets, making the whole Euryale leaf rot.

[control] in addition to rotation and non-partial application of nitrogen fertilizer, Euryale leaf spot can also be foliar sprayed with carbendazim (50% wettable powder) 400 × 500 times.

2. Leaf tumor disease

[symptoms] the pathogen was fungus, which occurred more frequently from July to August. At the beginning of the disease, the foliar surface appeared light green macula, and the posterior eminence was tumorous, with a diameter of 440 cm and a height of 2 cm.

[prevention and treatment] in addition to crop rotation, thickening leaf tumor disease can also be foliar sprayed with methyl topiramate 800 / 1000 times and 0.2% potassium dihydrogen phosphate during the onset season.

3. Anthrax

[symptoms] anthracnose mainly occurs on plant leaves, often harms leaf edges and tips, and in severe cases causes more than half of the leaves to wither and blacken and die.

[prevention and control] remove diseased plants and diseased leaves, apply 1000-1500 times of Baogong wettable powder with 50%, spray or pour water, once every 7 days, 2 or 3 times in a row.
