How to select and soak the seeds of zucchini?

1. Seed selection

Before the zucchini seeds are sown, we must first choose the zucchini seeds. The seeds should be fresh, glossy and with high germination rate. For some seed coat dull and yellowing phenomenon, then generally stored for a long time of old seeds, the germination rate of this kind of seeds is generally low, not suitable to choose. Then we have to pick out the impurities in the seeds, the seeds of diseases and insect pests and the seeds with wounds to ensure the overall quality and germination rate of the seeds.

2. Soaking seeds

Remove sundries, select clean and full seeds with a weight of about 200g, place them in tile basins or other oil-free containers, soak them in cold water, then scald the seeds with warm water of 50 ℃ and 55 ℃, keep them stirring continuously, keep them cool to 20 ℃ for 20 minutes, naturally cool to 20 minutes, soak the seeds for 6 hours, and then soak them with 1% potassium permanganate for 2030 minutes to disinfect and sterilize. Air-dried, to semi-dry can be heated to accelerate sprouting, the appropriate temperature is 25 ℃. If the amount of seed is large, it can be turned when sprouting, in order to promote sprouting neatly, but no longer turn after budding.

Second, what are the seedling methods of zucchini?

Prepare the nursery bed and pour enough warm water of about 35 degrees into the soil. When the water seeps into the lower layer of the soil, the culture soil on one side of the upper layer of the soil can be sown. Zucchini seedling method is mainly to raise seedlings in a nutrition bowl, each nutrition bowl can sow a seed, after sowing to cover a layer of about 4 cm of nutrient soil. In general, after all the nutrition bowls have been sown, they should be covered with another layer on the whole bed, and then properly covered with plastic film to maintain soil moisture. Seedlings can emerge after about 7 days. When about 75% of the seedlings are unearthed, the plastic film should be removed to avoid burning seedlings.

The above is the introduction of zucchini. Before planting zucchini, farmers should choose varieties with high quality, high yield, disease resistance, wide adaptability, moderate maturity and not running seedlings after setting fruit. For example, Golden Apple 12, Ruifeng 9, "Golden Beauty" Snow White 5 and so on.
