The latest seed price and planting method of water chestnut

Water chestnut is the fruit of the annual herbaceous aquatic plant of the rhombus family, also known as Fengling, Wuling, water chestnut, etc., which is native to the warm areas of Europe and Asia, but only China and India have carried out domestication and cultivation. It is most cultivated in southern China, especially in the Taihu Lake region of the lower reaches of the Yangtze River and the Pearl River Delta. Let's take a look at the seed price and planting method of water chestnut.

How much is the water chestnut seed per jin?

The price of water chestnut seed is about 10-15 yuan per jin, but the price varies greatly due to the quality, variety, producing area and market of the seed. There are many cultivated varieties of water chestnut, and the selection of excellent varieties is not only the basis of high yield, but also the key to compete for the season, occupy the market early and improve economic benefits. The early and middle ripening varieties of large water chestnut can be selected mainly for raw food. Wuling varieties with late maturity can be planted with high yield.

What are the varieties of water chestnut?

1. Shajiaoling: medium mature varieties, sown by Qingming and Grain Rain, harvested by the Beginning of Autumn and the End of Heat, tough rhizome, small dense leaves, small fruit shape, 400 kilograms per mu, green white and thick skin, suitable for cooked food, resistance to wind and waves, resistance to deep water and lean land.

2. Shuihongling: precocious varieties, sown in Qingming Festival, the Beginning of Autumn began to harvest tender turtle, the End of Heat and Frosts Descent harvested old diamond, with large fruit shape, high water content of diamond meat, yield of 800kg to 1000jin per mu, suitable for raw food, not resistant to deep water, not resistant to wind and waves.

3. Xiaobai Ling: middle and late maturing varieties, sowing in Qingming Festival, harvesting from White Dew to Frosts Descent, hard meat, suitable for cooked food, small fruit shape, 600-1200 jin per mu, strong growth potential, strong resistance to wind and waves, wide range of growth adaptation, suitable for deep water cultivation.

4. Daqingling: medium mature varieties, sown in Qingming Festival, harvested from White Dew to Frosts Descent, medium quality, large fruit shape, green and white skin, thick pericarp, hard meat, suitable for cooked food, yield of 1000kg to 1200jin per mu.

5. Nanhu Ling: early and middle ripe varieties, sown in Qingming Festival, harvested from the End of Heat to Frosts Descent, good quality, hard meat with japonica, medium fruit shape, yield of 1000kg to 1200jin per mu, moderate water level, fertile soil and weak resistance to wind and waves.

The planting method of water chestnut

The main results are as follows: 1. Seedling field selection: seedling fields with shelter from the wind and sun, fertile soil, water depth of 10 to 50 cm and convenient drainage and irrigation should be selected. Duckweed and sponges in the surface of the seedling field should be removed before raising seedlings, and plastic film should be buckled in advance for seedling raising and planting.

2. Sowing method: the ponds with shelter from wind, shallow water level, fertile soil and convenient drainage and irrigation were selected as seedling ponds in the Yangtze River basin from the Spring Equinox to Qingming. The seedlings were sowed on demand according to the row spacing of 1 meter square. The amount of seeds per mu was 6590 kg, which could be used for 8 mu of diamond ponds.

3. Transplanting and planting: on the same day, the seedlings were planted on the same day. Generally, the row spacing of shallow water turbot was 1.52m, the hole spacing was 1.52m, the planting distance of each hole was about 230m, the distance between rows of deep water turbot was 2.53m, the distance between holes was 2mm 2.5m, and each hole was planted with a bunch of about 8000m.

4. Rational fertilization: the amount of fertilizer needed for water chestnut is more concentrated. 2000 kg of pig manure or rotten mud manure can be applied per mu before planting, and 5 kg urea is applied as quick-acting fertilizer per mu after germination. After flowering, it is divided into 2 to 3 times combined with disease prevention and pest control and foliar spraying with 2-3 packets of strong yield-increasing hormone or 2% potassium dihydrogen phosphate.

5. Weeding at the right time: there are many kinds of aquatic weeds in Lingtang, such as Euphorbia angustifolia, Pteris vittata, bryophytes, etc., which must be removed manually in time, otherwise it will affect the photosynthesis of water chestnut. Weeds are generally cleared every 10 days after transplanting until the water surface is covered.

6. pest control: the common pests in water chestnut are aphids and leafhoppers, which can be controlled by trichlorfon or dipterex spray at the initial stage, and the common disease is mainly rhomboplague. Jinggangmycin plus carbendazim spray can be used in the early stage of the disease.

7. Timely picking: the water chestnut is ripe 20-30 days after flowering, harvested as vegetables or eaten raw when the sepals fall off and the pericarp is not fully hardened, and picked when ripe, processed or left seeds must be fully mature. Early-maturing varieties are picked every 5 days and late-maturing varieties are picked every 7 days.
