Method and time of raising seedlings of balsam pear

The method of raising seedlings of balsam pear: first prepare the nutritious soil, in order to prevent fungal diseases, soak the seeds in carbendazim solution for about 1 hour, then soak them in warm water to accelerate germination, control the temperature, ventilate in time, and sow seeds after budding. Seedling raising time of balsam pear: seedlings are generally raised in greenhouses or greenhouses in the north from the end of March to the beginning of April, sowing in the Yangtze River Basin in mid-March, and sowing in spring, summer and autumn in South China.

1. Time for raising seedlings of balsam pear

1. Balsam pear was sown in greenhouse or greenhouse from the end of March to the beginning of April and planted in early May.

2. The Yangtze River basin was sown in the middle of March and planted in the middle of April.

3. In South China, seeds are usually sown from January to March in spring, from April to May in summer and from July to August in autumn.

2. Seedling raising methods of balsam pear

1. Prepare nutritious soil

The main results are as follows: (1) Balsam pear needs to prepare nutritious soil 4-5 months before sowing. Farm manure which has not been planted with melons can be selected and put together for fermentation. If it is too late to ferment, disinfect it with disinfectant after the nutrient soil is stacked.

(2) first dilute the disinfectant according to a certain proportion, spread it evenly on the soil, then mix it with the soil evenly, cover it with a plastic film and seal it for about 3 days, spread out the soil for about 7 days, and wait for the effect to dissipate, you can use it, or you can buy the finished nutrient soil directly.

2. Seed disinfection

The main results are as follows: (1) balsam pear can be sowed by dry kernel direct sowing or soaking seeds to accelerate germination before sowing, and the seeds need to be disinfected before sowing to prevent the seeds from carrying bacteria.

(2) first, soak the seeds in clean water for about 4 hours, then remove the seeds and soak them in carbendazim and other solutions for about 1 hour, which is beneficial to prevent fungal diseases. finally, the seed surface can be washed with clean water to accelerate germination, or sow directly.

3. Soaking seeds to accelerate germination

1. Soak the sterilized seeds in warm water of 55 ℃. In order to heat the seeds evenly and prevent scalding, stir continuously until the water temperature drops to about 35 ℃.

2. In order to absorb enough water, the seeds can be soaked in water for about 7 hours, or the stolen goods on the surface of the seeds can be soaked clean, and then the seeds can be air-dried, wrapped in a wet sandcloth and placed in an environment with a temperature of about 32 ℃ to accelerate germination.

3. When promoting germination, you need to wash the seeds with 32 ℃ of warm water every day, which can improve the permeability of seeds and promote their germination. In about 4 days, most seeds will be white and can begin to sow.

4. Sowing and raising seedlings

The main results are as follows: 1. First prepare the seedling bowl, load it with nutritious soil and place it in the seedling bed, then pour water thoroughly. After the water permeates completely, it can cover a layer of fine soil, and then sow seeds.

2. A seedling bowl can sow a seed and cover with soil and plastic film after sowing, which can increase the temperature of the seedling bed and thus increase the germination rate. After emergence, the temperature should be controlled at about 22 ℃ and ventilated in time.

3. In order to ensure sufficient light of the seedlings, the plastic film is opened during the day and covered at night. The plastic film can be removed about 3 days before transplanting, which can improve the cold resistance of the seedlings.
