How to plant water chestnut (sowing time) how to preserve water chestnut seeds

Water chestnut is very common in life and is loved by many people because of its rich nutritional value. And water chestnut contains a lot of starch, can be used as a staple food to eat, at present in many places in southern China are planted. What is the planting method of water chestnut? May wish to follow the small series together to learn more about it.

How to plant water chestnut (sowing time)

1. Planting time: water chestnut is generally sown in the middle and lower reaches of the Yangtze River from late March to early April, and early maturity varieties begin to be harvested in early and mid-July, and generally end in late September to early October.

2. Selection of seedling field: seedling field should choose fields with wind and sun, fertile soil, water depth of 10- 50cm and convenient irrigation. Before seedling cultivation, duckweed and cotton wool in seedling field should be cleaned up. Greenhouse seedling cultivation and planting should be covered with film in advance.

3. Sowing method: From the spring equinox to Qingming in the Yangtze River Basin, ponds with wind protection, shallow water level, fertile soil and convenient irrigation shall be selected as seedling ponds. Seedling shall be sown according to the row spacing of 1 meter square. The seed quantity per mu shall be 65-90 kg, which can be used for 8-10 mu of water chestnut pond.

4. Transplanting and transplanting: planting on the same day of seedling emergence. Generally, the row spacing of shallow water rhombus is 1.5 - 2m, the hole spacing is 1.5- 2m, and a bunch of rhombus seedlings are planted in each hole. The row spacing of deep water rhombus is 2.5- 3m, the hole spacing is 2- 2.5m, and a bunch of rhombus seedlings is planted in each hole. About 8-10 plants.

5. Reasonable fertilization: the fertilizer required by water chestnut is relatively concentrated. Before planting, pig manure or decomposed mud manure can be applied to each mu. After germination, 5 kg urea can be applied to each mu as quick-acting fertilizer. After flowering, 2-3 times combined with 2-3 packs of strong yield-increasing factor or 2% potassium dihydrogen phosphate can be sprayed on the leaves.

6. Timely weeding: There are many kinds of aquatic weeds in the water chestnut pond, such as plantain grass, centipede grass, moss grass, etc., which must be removed manually in time, otherwise it will affect the photosynthesis of water chestnut. Generally, weeds are removed every 10 days after transplanting until water chestnut is filled with water.

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

How to preserve seeds

1. The selection has the inherent characteristics of this variety, the shape is regular, the skin color is deep, there is no disease and insect pest, the skin is thin and the meat is thick, the fullness is ripe, and the floating fruit is removed by placing in water, and the sunken fruit is left for seed.

2. The loss of winter storage is generally about 30%. In order to meet the seed consumption of a certain planting area, the loss should be estimated. The rhombus seeds are not resistant to drying and should be stored in water. They should be packed in woven bags and fixed with ropes. They should be placed in fields with hot spring water and sunk into water for winter. Keep the water flowing and not freeze the water chestnut seeds. In the spring of the following year, they were picked up, washed and sown.

Where does the water chestnut grow?

1. Water chestnut is generally planted in wet mud in temperate climates, such as ponds and swamps. The climate should not be too cold, preferably between 25 and 36 degrees Celsius. The water depth must be 60 centimeters.

Water chestnut is native to warm regions of Europe and Asia. However, only China and India have domesticated and cultivated. In southern China, it is cultivated especially in Taihu Lake area and Pearl River Delta area in the lower reaches of Yangtze River, and Honghu Lake in Hubei Province is the most abundant. Artificial cultivation in Anhui, Jiangsu, Hunan, Jiangxi, Zhejiang, Fujian, Guangdong, Taiwan and other provinces in the middle and upper reaches of the Yangtze River. Russia, Japan, Vietnam, Laos, etc. are also cultivated.

The planting prospect of water chestnut

The prospect of water chestnut planting is first considered from the perspective of the state. It is a poverty alleviation project supported by the state at present, so the cost is very low. Although the profit may not be much, it can at least guarantee that you will not lose money, otherwise how can you help the poor? Secondly, there are still many potential effects of water chestnut that have not been developed, so there is still a great market development prospect after that. Finally, although the price of water chestnut is not high at present, the demand is large enough, so it is still possible to seize a wave of market and wait for subsequent development.

The planting method of water chestnut is introduced here first. Does it feel easier? Moreover, the planting cost of water chestnut is also relatively low, and there is support from the state. Generally speaking, planting water chestnut is still a relatively promising project.
