How to choose melon seeds? What are the methods of raising seedlings?

There is more demand for melons in the market, and many farmers have planted them. However, before muskmelon cultivation, farmers had better carry out seedling work, so as to ensure that muskmelon seedlings are uniform, strong, promote early maturity, and achieve the purpose of increasing production and income. So how to choose melon seeds? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to select melon seeds?

Muskmelon seeds should be selected according to the seed characteristics of the variety, the shrunken seeds and damaged incomplete seeds should be removed, and those with full, moth-free, mildew-free and mechanical damage should be selected, and then the germination test should be carried out. Those with a germination rate of more than 90% are good seeds, about 85% are general seeds, and less than 70% are poor or aged seeds, so don't use them.

Sun the selected seeds, then put them in 55 ℃ warm water of 5-6 times the seed amount, stir continuously for about 15 minutes, when the water temperature drops to about 30 ℃, soak in the greenhouse for about 5 hours, rub off the gelatinous material from the seed epidermis and rinse clean.

Second, what are the seedling methods of muskmelon?

1. Raising seedlings in greenhouse

Can be divided into heating greenhouse, solar greenhouse (greenhouse). The heating greenhouse is to raise the indoor temperature by fire or water vapor, which is used for extra-precocious cultivation and seedling cultivation; the solar greenhouse (greenhouse) relies on sunlight to raise the ground temperature, and other heat preservation measures are taken without heating, such as setting a small arch shed in the greenhouse, covering grass, and so on. suitable seedlings can be cultivated for double mulching in greenhouse or small arch greenhouse in early spring. This kind of greenhouse has the advantages of low cost and good tightness, and it is widely used in various places.

2. Nursery in hotbed

According to the different heat sources, the commonly used are brewing heat hotbed, electric heating hotbed, fire Kang bed. The heating hotbed heats the bed soil with the heat released by the decomposition of organic matter such as barnyard manure; the electric heating hotbed uses electric energy to heat the bed soil, which consumes more electricity and costs more; the Kang bed is built with bricks at the bottom of the bed and is covered with cultivated soil. according to the changes of external air temperature and the growth needs of seedlings, temporary fire (firewood or coal can be) to heat up.

3. Raising seedlings in cold bed

The simplest form of seedbed, the use of sunlight during the day to increase the temperature of the seedbed at night to cover the grass. In order to make full use of solar energy and improve the heat preservation effect, the bed site is located in the open area with high dryness and sufficient light, and there is a wind barrier around it. The width of the seedbed is about 1.3m. The length of the seedbed depends on the topography and the number of seedlings, generally not more than 10m. The depth of the bed pit is 25~35cm, the bed wall should be straight, the soil beside the bed should be compacted, bamboo should be used as the arch frame, the arch frame should be covered with agricultural film, and all sides should be sealed with mud. The cold bed only uses sunlight energy and heat preservation measures to improve the bed temperature, but the warming effect is poor, and it can not improve the soil temperature of the seedling bed, so the effect is poor. Shading seedling bed is to cover sunshade facilities such as sunshade net on the cold bed to avoid sunburn of seedlings and cover greenhouse film to prevent rain on rainy days.

The above is the introduction of muskmelon, whether there is a profit in melon planting depends on each link of production, and there are many basic requirements in the process of raising seedlings, which lays a good foundation for melon production and achieves a good harvest.
