How do cucumber seeds grow? Squamous cucumbers usually use sexual reproduction (seed propagation). However, because cucumber juice contains certain plant alkaloids and organic acids that inhibit growth, they inhibit the germination of seeds. If you do the treatment before sowing, it will be very difficult to germinate even if you sow the cucumber. The following Xiaobian will tell you how to plant the cucumber seed!
Choosing cucumber seeds
For the varieties of cucumber seeds planted in previous years, the growers can feel comfortable choosing because the planting conditions and harvest conditions of this species are clear, but for seed varieties that have not been planted, it is better to plant them in small areas if the budding effect is achieved. And the growing conditions are satisfactory, and then sowing a wide range. In addition, before sowing, it is best to test the seed germination rate and germination potential of the purchased seed. The germination potential of the cucumber seeds is rapid and neat, and only the budding rate of more than 90% can meet the requirements of planting and ensure the harvest. .
Of course, different varieties of cucumber seeds adapt to different cultivation conditions, some suitable for open field cultivation, some suitable for greenhouse cultivation, friends in the purchase of cucumber seeds should be specific analysis of the specific circumstances, select the suitable varieties for planting.
Cucumber seed processing
According to a survey of a variety of cucumber infestation diseases, about 34.6% of seeds are transmitted by bacteria, mainly including anthrax, scab, black spot, and bacterial keratoses, so seeds should be disinfected prior to sowing. . There are many methods of disinfection, of which the heat sterilization method is better, has the advantages of simple operation, wide sterilization spectrum, safety to seeds, environmental protection, cost savings, etc., and is suitable for adoption by a large number of farmers.
1. Warm water pre-soaking: Immerse the cucumber seeds in room temperature water and pre-soak for 4 hours, remove and immerse in 55°C hot water, heat and sterilize for 15 minutes, then remove and put into cool water to cool down, then transfer to germination or sowing . The precautions are the water temperature and time strictly complying with the technical requirements.
2. Seed Disinfection: Seed disinfection is the most economical and effective method for preventing and controlling various infectious diseases and insect pests. It is an indispensable measure to prevent plant diseases and insect pests. Due to the small amount of cucumber seeds used for treatment and the long harvest time of cucumbers, there is almost no problem with pesticide residues. Therefore, it is also an important measure to promote the use of pollution-free vegetables.
1 Seed coating: The seed coating agent contains fungicides and insecticides that kill pathogens and underground pests, as well as trace element fertilizers and plant growth regulators that can promote seed germination and cucumber growth. Some of the commodity seeds are already coated before delivery, and the use of such seeds does not require disinfection.
2 Warm soup soaking: Warm soaking is a method of killing germs on the surface of seeds by high temperature using the difference in tolerance of dry species and germs to high temperatures. The dried seeds were put into warm water of 55-60°C, stirring constantly, and hot water was continuously added, and the water temperature of 55-60°C was maintained for 10 minutes. The temperature was lowered to 28-30°C and soaked for 4-6 hours. The germination was performed after panning.
3 Pharmaceutical soaking: First, use 72.2% Prokary water or 25% metalaxyl wettable powder 800 times soaking for 20 minutes to prevent fungal diseases of cucumber seedlings. Second, 50% of methine WP can be soaked for 500 minutes to prevent anthracnose and stem blight. Thirdly, disinfecting with 2.5% Shiloh suspension seed coating agent can not only kill the pathogenic fungi latent in the seed coat, but also penetrate into the seeds to kill the pathogenic fungi invading the seeds and effectively prevent the melons from seedling stage. Dysplasia, blight and other diseases. Fourth, in order to prevent viral disease caused by seeds, it can be soaked in 10% trisodium phosphate solution for 20 minutes. Fifth, the 1 million-unit agricultural streptomycin 500-fold dilution soaked for 2 hours can prevent bacterial diseases.
No matter which kind of agent is used for soaking seed, the seed should be washed with water after soaking so as to prevent the occurrence of phytotoxicity.
Soaking and Germination
1. Seed Soaking: Seeds soaked in warm soup or soaked in pesticide can be soaked in the temperature of 25-30°C for 4-6 hours, so that the seeds can absorb 50-60 % of their dry weight, and then they can be washed by hand. The mucus, remove the germination inhibitors, rinse the impurities and rinse the seeds, and rinse with water.
2. Seed germination: Seeds after soaking are wrapped in clean wet gauze. The wet towels on the outside are wrung and put in place at 25-30°C. Wash 1-2 times daily with warm water, continue to germinate after panning, germinate at a temperature of 25-30°C for 16-20 hours, sow seeds that have germinated in batches and sow or place at 5-8°C Under the conditions, all the seeds are sown together.
