How to Grow Edible Aquatic Plants Arrow (Can Arrow be Cultured in Water)

1, site selection: arrowhead cultivation needs sufficient water, so it should be planted in sand-enclosed land with convenient irrigation and drainage and deep and fertile soil layer.

2. Base fertilizer: Before planting, 2,500kg of green manure or pig manure 1 0,000kg is generally applied as base fertilizer, and planting is carried out after 1 week.

3. Collect Sagittarius Sagittarius seedlings: The standard Sagittarius Sagittarius seedlings are required to be stout, with three leaves and a height of about 25 cm. Cut off the extra leaves and remove the old roots and leaves at the same time.

The first batch of mushroom seedlings, called "vegetables" by mushroom farmers, were collected in the first half of August. Because of the early planting time, the seedlings are big, strong and grow fast, accounting for about 80% of the total seedlings. Topdressing the first batch of seedlings once after picking; 15 days later, the second batch of seedlings can be harvested. Mushroom farmers call it "washing the ground", accounting for about 20% of the total seedlings. "Washing the ground" seedlings can only be planted in early September, that is, before "Bailu". If the amount of seeds used is large and the supply of seedlings is insufficient, the first tillering seedlings can be planted from "vegetables" These seedlings are called "new bags" by farmers, and the seedlings of "new bags" are usually planted before September 20.

5. Planting requirements: It is generally arranged to plant from August 8 to September 20, with a plant spacing of 2 1cm and a row spacing of 50 cm, with about 6,500 plants per mu. The field should be flat and shallow, and irrigation and drainage pits should be dug. Shallow transplanting is required when planting, which is beneficial to the early growth and rapid development of seedlings. Every other row, 2 ~ 3 plants are used as spare seedlings from the heel, so as to make up for the shortage in time and ensure the whole seedling.
