How to select Malabar spinach seeds? What are the seedling-raising methods?

Speaking of Malabar spinach, I guess many friends are quite familiar with it. It is very common in daily life and is widely grown in both the north and the south. Malabar spinach has relatively high nutritional value, a very fresh fragrance, and tastes crisp and refreshing, so it is welcomed by many consumers. So how should Malabar spinach seeds be selected? What are the seedling-raising methods? After reading the following, everyone will understand.

1. How to select Malabar spinach seeds?

1. Besides mastering the planting time for Malabar spinach seeds, choosing good seeds is also very important. When purchasing, choose packaged seeds that are plump and within the production date, as this can increase the germination rate. Because Malabar spinach seeds are very hard and thick, if they are planted directly in the ground like this, it will take a long time for them to germinate, so it is necessary to soak the seeds in advance to promote germination or rub off the seed coat in advance. No matter which treatment method is used, the purpose is to speed up the germination rate.

2. Choose varieties with strong growth vigor, many branches, tolerance to high temperature, tolerance to drought, tolerance to moisture, and high nutritional value; with thick stems, thick leaves, tender leaves that are soft, smooth, and fleshy. For example, Large-leaf Malabar spinach.

2. What are the seedling-raising methods for Malabar spinach?

1. Direct seeding cultivation

For a pot with a diameter of 20 cm, sow 3 to 4 seeds per pot to ensure the emergence rate. To facilitate emergence, the seeds can be soaked for 1 to 2 days before sowing and germinated at a temperature of about 30°C. When the seedlings have 3 or 4 true leaves, thinning can be carried out, leaving 1 seedling per pot. When the seedlings are 10 to 15 cm tall, they can be harvested.

2. Seedling raising and transplanting

Sow dry seeds. At a suitable temperature of about 28°C, seedlings emerge in 3 to 5 days. If the soil temperature is low, sow after promoting germination. If not direct seeding but seedling raising is chosen, they can be divided into pots for transplanting and setting out when they have 4 to 5 true leaves.

3. Planting methods for Malabar spinach

1. Fertilizing and land preparation

Malabar spinach is a relatively cold-sensitive vegetable, so its adaptability to high temperatures is quite good. It is generally more suitable for planting in loose sandy soil. Malabar spinach needs sufficient water throughout its entire growth process, so when choosing land, pay attention to having a good irrigation and drainage system. When preparing the land, special attention should be paid to applying sufficient farmyard manure as base fertilizer. At the same time, deep plowing and deep planting should be carried out. After turning the land over, beds should be made. Generally, making beds about 1 m wide is enough. When making the beds, make the field ditches used for irrigation and drainage so they can be used directly when needed.

2. Seed treatment

Before sowing, the seeds should be soaked, because the seed coat of Malabar spinach is relatively hard. If simply sown directly, they may not germinate for a very long time. When soaking the seeds, pay attention to the water temperature and time. First soak them in water at about 50°C for half an hour, then soak them in water at about 30°C for 5 to 6 hours. Finally, remove the seeds and place them in a warmer place to promote germination. Usually after 3 to 4 days, the white sprouts will appear, and then they can be sown.

3. Sowing and setting out

There are two sowing methods. The first is to sow the seeds evenly on the bed at a spacing of 40 cm between rows and 30 cm between plants. The second is to first sow the seeds for seedling raising, and when the seedlings grow 3 to 4 leaves, transplant them. The distance between each plant and each row is also 40 cm between rows and 30 cm between plants.

4. Field management

After setting out, if there is no rain, water once every 3 days. After it grows new roots, apply the first fertilizer. If it rains after transplanting, apply some urea during the rain, as this can promote its growth. Malabar spinach can be harvested once each time it grows taller for a period. After harvesting, apply fertilizer once, which is beneficial for it to quickly grow new leaves and branches.

5. Disease prevention

The main diseases of Malabar spinach are brown spot disease and gray mold. Brown spot disease mainly harms the leaves, causing brown spots to appear on the leaf surface. In severe cases, the whole plant withers. Gray mold, on the other hand, has water-soaked light green spots, and diseased stems easily collapse and rot. We generally spray once every 5 to 7 days with a 600-fold dilution of 72% Kelu wettable powder, or a 600-fold dilution of 75% chlorothalonil wettable powder, or a 1000-fold dilution of 70% thiophanate-methyl wettable powder for control. Doing this continuously 2 to 3 times basically solves the problem.

The above is all the content the editor wants to share with everyone today. When selecting Malabar spinach seeds, you can refer to the suggestions above, and the seedling-raising methods can also be appropriately adopted. If you are preparing to plant, some necessary methods still need to be kept in mind.
