How to choose and sprout water celery? What are the methods of raising seedlings?

Water celery, also known as wild celery, is an aquatic vegetable growing in ponds, rivers and paddy fields. It has delicious taste and high nutritional value. It is mainly distributed in the central and southern regions of China, and the cultivated area is larger in Jiangxi, Zhejiang, Guangdong, Yunnan and Guizhou. So how to choose and sprout water celery? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to choose and sprout water celery?

We need to select the seed stem and accelerate the germination of the seed stem before sowing. Seed stem we generally choose a more robust, disease-free, more vigorous stem as the seed stem. Then tie the selected seed stems together, each about 20 to 30 centimeters thick. After they are tied up, pile them in a place where there is no sunlight and cover them with a layer of straw. Finally, water is watered once a day in the morning and once in the evening, which usually takes about a week to take root, and the rooting stems can be planted.

Second, what are the breeding methods of water celery?

1. Seedling raising time

The suitable planting period of water celery is from mid-late August to early September. In order to prevent wilting shoots in the hot sun, planting should be carried out in cloudy or sunny evenings.

2. Seedling preparation

It is necessary to drain water before planting, leaving only a thin water layer of about 1 centimeter, usually by planting at the edge of the field and sowing seeds in the field. The method is as follows: the base of the budding stem is facing the ridge of the field, the tip is facing the middle of the field, keeping a distance of 3-4 cm between the plants, and planting neatly in a circle around the paddy field. Strip sowing is carried out in the middle part of the field, and the distance between seeds and plants is 5-6 cm. When sowing seeds, it is best to reduce the overlap between species and plants as much as possible, and it is best to use bamboo poles or hands to pick the seeds from denser places to sparse places, so that the whole field can be evenly distributed. After planting, put water into the paddy field, the standard is to keep more than half of the ditch water in the ditch, the border surface is fully moist without stagnant water, so as to avoid scalding buds due to the rise of water temperature.

3. Seedling raising method

(1) Sponge

Dip the sponge of the same size as the seedling tray with water, put it into the seedling tray, continue to add water to the seedling tray, and gently pat the sponge with your hand while adding water to make it absorb enough water.

(2) sowing

Put the seedling tray flat in the greenhouse covered with greenhouse film or other places where there is plenty of sunshine and can protect against wind and rain, birds and animals. Spread the treated celery seeds evenly on the sponge full of water, so that there are about 10 seeds on the surface of each small sponge, too much or too little is not suitable.

Spray water with a sprayer after sowing to make the seeds absorb enough water and avoid seed accumulation.

(3) Management

Spray water more than 2 times a day after sowing and 4 times a day at high temperature to keep sponge and celery seeds moist. After 15 days, when there are 3-4 water celery buds on each sponge, some foliar fertilizer of potassium dihydrogen phosphate can be added to the spray water, and the initial concentration should not exceed 0.5 ‰. After 20 days, the concentration can be increased to 1 ‰. It was colonized when there were 3 or 4 true leaves in about 30 days.

The above is the introduction of water celery, if water celery wants to achieve high yield, raising seedlings is a very key link. Water celery is an important aquatic vegetable supplied in winter and spring, which is mainly fed by tender stems and leaves. It is rich in nutrition and plays a certain role in hemostasis, lowering blood pressure and lowering blood lipid.
