How to grow western sea shoots

Western sea shoots are known as "sea ginseng" and "plant seafood", also known as sea bean and so on. they are new health vegetables introduced and domesticated from abroad and irrigated by pure natural sea water. So, how do you grow western sea shoots?

1. Soil

Western sea shoots are suitable for growing in soil with a salinity of 15% Mel 30%, and do not require high soil texture, such as sand, clay and sandy loam. Before planting, the consolidated saline-alkali land should be ploughed first to make the soil loose and ventilated. According to the different soil conditions, two types of sunny planting and shady planting are adopted, and shady planting is adopted for the improved land with good drainage and fertile soil, with a border width of 1-15m and a monopoly width of Q5Melet 1m, which is convenient for harvesting and installation of irrigation facilities; for saline-alkali land that has not been improved, it is easy to accumulate water because of soil consolidation, so it adopts the method of sunny planting.

Second, sowing seeds

When sowing in spring, the suitable temperature for seed germination is about 15 ℃. Full, dry, disease-free and pest-free seeds are selected and dried for 1-2 days. Before sowing, mix sand at the ratio of 1:5, and sow or strip sow seeds per mu is about 2kg. After sowing, cover the soil around 5cm.

III. Field management

1. Irrigate

Sea water or underground brine is used as the source of irrigation, and the salinity of sea water is maintained at 25%, 30%. If the salinity is too high, fresh water should be diluted. Due to the hardening of saline-alkali soil due to the lack of water and the large water demand for the growth of western sea shoots, micro-spray belt is generally used for irrigation in order to save cost. In the week from sowing to emergence, sprinkler irrigation should be done once in the morning and in the afternoon to ensure that the soil is moist. After the seedlings are unearthed, the times of irrigation can be reduced appropriately, and the times of irrigation can be adjusted according to the soil moisture during the whole growing period. Because the exuberant growth period of western sea shoots is in summer, there are more Rain Water and need to be drained in time.

two。 Fertilizer application

Western sea shoots have less demand for fertilizer, generally applying organic fertilizer 200kg per mu or so. The principle of fertilizing based on base fertilizer and supplemented by topdressing was adopted. In order to reduce waste, the method of ditch fertilization was adopted when applying base fertilizer, the depth of ditch was about 20cm, and the fertilizer was scattered in the ditch. After uniform fertilization, the soil was raked flat. When the western sea bamboo shoots grow for 45 days, they can grow to 15cm and apply organic fertilizer once. Using the method of spreading, applying organic fertilizer 30kg per mu or so. After topdressing, it is necessary to spray irrigation in time to let fertilizer seep into the soil to prevent the growth of branches and leaves, and it is necessary to interseedling western sea shoots; in addition, in order to make full use of land resources, it is necessary to replenish seedlings of western sea shoots.

3. Loosen the soil and weed

For seriously consolidated saline-alkali land, we should often hoe to ensure that the soil is loose; in addition, for land with loose and fertile soil, we should often weed to prevent weeds from competing with western sea shoots for nutrition.

4. Harvest

After 70 days of growth, the plant height can reach 30cm. At this time, the growth of western sea shoots can be promoted by picking fresh vegetables. When picking, the fleshy stem of western sea bamboo shoots is tender and pointed, and the picking length is 6-10cm. After picking off the tender tip, the western sea bamboo shoots will continue to grow new branches from the node, and vegetable farmers can pick them continuously from August to October.

Western sea shoots such as jade color, shaped like coral, taste crisp and tender, have a unique delicious seafood flavor, rich nutritional value. There are broad prospects for planting, and farmers with ideas can try.
