How to choose and keep the towel gourd? Methods of accelerating germination and Seedling-raising techniques of towel Gourd

Towel gourd is one of the most common vegetable crops. In rural areas, many friends like to plant several trees in their own courtyard. Towel gourd is a kind of temperature-loving and heat-tolerant crop with strong adaptability and lax requirements on soil. When farmers are planting towel gourd, the most important thing is to raise seedlings, so how to choose and keep towel gourd? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to choose and keep the towel gourd?

1. Seed selection

Towel gourd seed shell is very hard, farmers in the purchase of towel gourd seeds, must choose full and full. Seeds without mildew and yellowing in appearance.

2. Keep the seed

Towel gourd seed should be left root gourd, because the root gourd fruit early, long growth time, full seeds, offspring also early melon. Long towel gourd if you leave root gourd to do melon, because the melon is too long, often rot on the ground, should leave just on the shed of the melon to do melon, melon shape to both ends of the slender towel gourd is better. Leave the melon until the skin turns brown, harden and dry, harvest, and ripen indoors.

Second, how do towel gourd seeds sprout?

1, towel gourd seeds soaked in 50 degrees water for 5-8 hours, put on a wet cloth or paper, pay attention to the humidity of the paper or cloth, do not drip, but not too dry.

2. Cover with moist paper or cloth to block the light.

3. The suitable temperature for towel gourd seed germination is about 28-30 degrees, so we must pay attention to heat preservation at night.

4. Generally speaking, the germination rate of towel gourd direct seeding is relatively low, especially in early spring, it is best to accelerate budding and dew before sowing. If seedling cultivation towel gourd seedlings must be transplanted before the first true leaf, otherwise it will affect the survival rate. The seedlings emerged 4-5 days after sowing and could be planted 3 days after emergence.

5. it is also worth noting that after soaking the towel gourd seeds, if you dry the seed coat with a cloth, then leave it for 1 hour, then put it into a container covered with wet paper or cloth, covered with soaked paper or cloth to germinate, the effect will be better.

The permeability of towel gourd seed coat affects the germination rate and germination energy of towel gourd seeds. Only after absorbing water from the seed coat and leaving it in air for a certain period of time, the seed coat permeability can be improved, thus the germination rate and germination energy can be improved.

3. Seedling raising methods of towel gourd

1. Variety selection

Towel gourd seeds should choose varieties with high quality, high yield, good commercial properties and suitable for the market, and long stick-shaped varieties should be selected for cultivation in winter and spring, and the market should be oriented to varieties from Hong Kong, Macao and South China, such as green, Shuangqing, green and so on. Summer and autumn cultivation should choose short stick-shaped varieties facing the island market, such as Thailand towel gourd.

2. Sowing time

Winter and spring cultivation is usually sown from November to January-February of the following year, and harvested from December to April of the following year. Summer and autumn cultivation is usually sown from June to September and harvested from July to November.

3. Seed treatment

In order to prevent seed infection and improve the uniformity of germination, seed treatment should be done before sowing. Seed drying can promote seed ripening and improve germination rate. Generally, seeds can be dried for 2-3 days before soaking seeds, seeds can be soaked with 10% trisodium phosphate for 20 minutes, and seeds can be soaked in 60 ℃-70 ℃ warm water for 10-15 minutes. When soaking seeds, keep stirring. When the water temperature drops to about 30 ℃, continue soaking seeds for 4-6 hours. Then remove the seeds and put them under the condition of 28 ℃-30 ℃ and rinse them with clean water 1-2 times a day, including a clean sand cloth for wrapping the seeds. The seeds can be sown after 3-4 days of exposure.

4. Sowing method

The survival rate of towel gourd transplanting is low, and the direct seeding method is generally used. From March to April, the soil preparation is made, the width is about 3 meters, the seeds are sowed and germinated, two rows are sowed on both sides of the border, the plant spacing is 35 cm, and the holes are opened. 3 seeds per hole, about 300-450 grams per hectare, single row planting, plant spacing 30-50 cm, 2 seeds per hole, depth 1-2 cm, seeds flat, soil field capacity 75%. If it is too dry, it can be watered a little. Cover the hay after sowing to keep warm and wet.

5. Seedling stage management

The temperature of the seedling stage was maintained at 25 ℃-32 ℃ in the daytime and 18 ℃-20 ℃ at night, which made the seedlings emerge quickly. Generally, all the seedlings could emerge in 4-6 days. After the seedlings were unearthed, the temperature should be lowered properly, about 22 ℃-28 ℃ in the daytime and 15 ℃ at night. If there is not enough water in the seedling stage, we should properly water or spray water, pay attention not to flood irrigation, but also pay attention to the prevention and control of diseases and insect pests. When the seedlings grow 2-3 true leaves, they can be planted in about 30-35 days.

The above is the introduction of towel gourd. Because the shape, peel and color of towel gourd are different, farmers should choose and buy towel gourd varieties according to different consumer markets.
