Muskmelon fragrance, also known as cantaloupe, is suitable for all ages of summer melons and fruits, melons for the popularity of consumers, the market is in short supply, then which variety of muskmelon is good to choose in the greenhouse? What muskmelon greenhouse planting techniques need to be mastered?

What kind of muskmelon should be chosen in the greenhouse?

1. Variety selection of muskmelon cultivated in greenhouse

(1) thick-skinned melon type, good color, melon shape, thick meat, sweet and juicy, resistant to transportation.

(2) the middle type of thin and thick skin, with the aroma of common melon and the fragrance of muskmelon with thick skin, has a high sugar content, so it is suitable for greenhouse cultivation and open field cultivation.

(3) thin-skinned melon has the advantages of early maturity, crisp flavor, strong disease resistance and so on.

2. Recommend muskmelon varieties in greenhouse

You can choose Zhongtian No. 1, Jinmei, Mitian, Dongfang Mi No. 1, Huami 0526, Xibaluoto, Jade Mushroom, Gulaba and so on.

What are the planting techniques of muskmelon in greenhouse?

1. Seed treatment

Dry the seeds for 1-2 days before sowing. Put the seeds in warm water of 55 ℃, stir quickly for 10 to 15 minutes, stop stirring when the water temperature drops to about 40 ℃, continue soaking for 3-4 hours, and wash the surface mucus of the seeds. The treated seeds were wrapped in wet sand cloth and germinated under the condition of 28030 ℃. The seeds can be sown when 80% of the seeds are white (it is best when the radicle length is 0.5cm).

2. Timely sowing time

It is appropriate to sow seeds from late January to early February. The sowing date of extra-precocious cultivation (shed width 8 meters, five-film mulch) can be advanced by about a month, and the seedling bed can be watered through the bottom water the day before sowing, covered with film and electrically heated to preheat the soil.

3. Sowing method

Choose sunny morning sowing, first insert a 1cm deep hole in the middle of the nutrition bowl, then put the seeds flat on the nutrition bowl, the radicle down in the hole, cover with sowing (cover mud every 15-25 years to mix seedlings with a packet of disinfection), cover soil thickness is 1.0cm. Immediately after sowing, set up a frame to cover the film, and cover the non-woven fabric at night to keep warm.

Waiting for 60% of the seedlings to emerge, 80% of the mulch will be removed in time to prevent late exposure from causing tall seedlings. If there are "capped" seedlings after uncovering the film, they can be removed manually in the morning.

4. nursery bed temperature management

Master two high and two low: that is, from sowing to emergence, the temperature is kept at 28: 32 ℃ during the day and 18-20 ℃ at night; from emergence to before the appearance of the first true leaf, the temperature is controlled at 20: 25 ℃ in the daytime and 15-18 ℃ at night, and the temperature is too high to open the leeward to cool down; the first true leaf expands to the third true leaf, 25: 30 ℃ during the day and 15-20 ℃ at night; drop one week before planting

5. Humidity management

Watering of the first true leaf is strictly controlled before birth to prevent quenching, blight and overgrowth of seedlings. In the future, with the increase of water demand of melon seedlings, the dry and wet degree of seedling bed soil will replenish water in time. When watering, try to choose when the greenhouse temperature rises around 10:00 in the morning on a sunny day. One week before planting, the moisture content should be tightened from the seedlings. The day before planting, the nursery bed should be injected with starting medicine overnight and watered once to prevent the soil from being loose during transplantation. Depending on the seedling fertilization, according to the seedling development and leaf color, combined with watering fertilization, the concentration of available fertilizer is less than 0.3%, and it can also be poured or foliar sprayed with commercially available nutrient liquid fertilizer. After pouring, it should be properly ventilated to avoid toxic gas damage to melon seedlings.

6. Lighting management

After the seedlings are unearthed, the seedling bed should increase the light time as much as possible. Therefore, in fine weather, the film should be uncovered early and late to prolong the light exposure time of seedlings, even in continuous rainy days, as long as the temperature in the greenhouse reaches more than 10 ℃, the film should still be exposed to scattered light. Seedlings under the condition of no light for a long time are easy to yellowing or overgrowth. When it is cloudy and sunny for a long time, the greenhouse film can not be completely opened, multiple vents can be opened to let the seedlings slowly adapt to 1-2 days, and then normal management.

7. Planting and density

When the melon seedlings reach three leaves and the seedling age is about 30 days, they can be planted. Extra precocious cultivation is usually planted in the middle of January. According to the weather forecast, choose cold tail warm head, sunny good weather planting. The greenhouse is 6 meters wide, with 2 rows in each greenhouse, and the plant spacing is 30cm. The density is about 600 plants per mu. 4 rows were planted in 8 meters wide greenhouse, each row was planted in the center, and the density was about 640 plants. When planting, dig a good hole according to the plant distance, fill the solid soil around the seedling bowl, and irrigate the planting water according to the soil moisture. After planting, set up a small ring shed and a simple small ring shed, cover the greenhouse film. Note that there can be no gaps around the membrane.

8. Pest control

The main diseases were diseases in seedling stage, such as quenching disease, blight disease and anthracnose. In management, the humidity of seedling bed was mainly controlled and insecticides were sprayed regularly to prevent it. In the early stage of the disease, it can be prevented and treated with 30% vaccine enemy 800x solution, 75% methyl topiramate 600,800x solution, 25% amicida suspension 1500 times solution and so on.
