What is the best variety of watermelon seedlings? What are the methods of raising seedlings?

Watermelon is one of the fruits that people eat most in summer, and the total planting area of watermelon in our country is also very large, and there are many varieties of watermelon. If fruit growers want to plant watermelon, it is right to choose a suitable watermelon seedling. So what kind of watermelon seedlings is the best?

What is the best variety of watermelon seedlings?

1. Early spring ruby

It is a very precocious small red flesh watermelon of the hybrid generation. It was planted in spring, harvested in May and matured 35 days after fruit setting. It is planted in summer and autumn, harvested in September and matured 25 days after fruit setting. The variety has a long oval appearance, clear green stripes, robust plant growth, 0.4-0.5 cm thick pericarp, crisp and tender flesh, central sugar content more than 12.5, single melon weight 2.0 kg, long preservation time and good marketability.

two。 Black beauty

Black beauty melon is a variety of watermelon, the fruit is long oval, the melon is small, the pericarp is dark black and green, with inconspicuous stripes. Sweeter than other varieties of watermelons, meat is more important than other varieties of melons.

3. Honey treasure

Mibao, also known as Taihei, the face of the young fruit is dark green, vaguely green stripes, and there are white fruit powder on the mature side. A single melon weighs 6-7 jin, and the big one can reach about 12 jin. The skin thickness is about 1.2-1.5, strong at the beginning, resistant to storage and transportation.

2. Seedling raising methods of watermelon

1. Seedling raising time

The period of watermelon breeding, that is, from December to February, is the coldest time in winter, especially before and after grafting. Because of the small seedling shed, imperfect heat preservation facilities and low temperature in the shed, many melon farmers often have low temperature obstacles in case of cold current. With the low temperature in the shed, the first thing that melon farmers think of is to improve the heat preservation of the seedling shed. In addition, improving the cold resistance of seedlings is also an important measure to deal with low temperature.

two。 Measures to strengthen thermal insulation and heating facilities

In addition to the original greenhouse film, thermal insulation and other thermal insulation measures, proper heating in the shed is also very necessary. In the past, vegetable farmers often use stoves to heat up, but the danger is high. Vegetable farmers must be prepared for protection to avoid harming seedlings.

In addition, if you want to cultivate strong seedlings, it is suggested that vegetable farmers install supplementary lights in the shed, heating and replenishing light should be taken into account, which has an outstanding effect on improving the quality of seedlings. In the event of a short-term cooling of the cold wave, vegetable farmers can use greenhouse heating blocks for short-term heating, and a seedling shed can use 2-4 blocks, which can burn continuously for 2.5 hours after lighting, and there is no open fire, so it is safe to use and quickly increase the night temperature above 5 ℃. Through the combination of a variety of measures, the light and temperature conditions of seedlings can be effectively improved, and the primary factors restricting the success or failure of seedlings can be solved.

3. Improve the cold resistance of seedlings

After emergence, foliar spraying of Shiyuan Taurus suspension calcium 1000 times, chitin 1000 times, white sugar 300 times can effectively improve the cell activity and enhance the stress resistance of seedlings.
