Bean planting knowledge
The long bean can be directly sown, or it can be transplanted and transplanted. Generally, it is transplanted by seedlings. By transplanting seedlings, it can appropriately inhibit vegetative growth, promote reproductive growth, and adopt seedlings for seedlings or nursery beds. The seeding amount per 667 square meters is about 2.5kg. Nursery is generally used in greenhouses, and nutritious soil seedbeds and nutrient spas should be prepared before sowing. The nutrient soil seedling bed should be ploughed in advance, and the hoe is fine and flat. The 1800 square meters of rotted organic fertilizer is about 1000kg. If the seedlings are used for nutrition, the diameter of the nutrient raft should not be less than 8cm and the height should not be less than 10cm. Then, on a flat bed, press 7 to 8 cm to see the seeds of 3 to 4 seeds full of seeds (3 to 4 seeds in the nutrient solution), pour the bottom water, cover the 0.5 cm thick nutrient soil, and then tiling. The mulch is then insulated with a small arch shed. After sowing, the seedlings can be emerged under normal conditions for 4 to 7 days. After the seedlings are unearthed, the mulch film should be removed in time, but the small arch shed still has to be exposed. After emergence, keep the temperature at 20~25°C during the daytime. In the greenhouse, it is necessary to pay attention to heat preservation, and also to ventilate and ventilate to ensure that the seedlings grow neatly and robustly; the seed germination period and seedling stage soil should not be too wet, so as not to reduce the germination rate. Or cause the seedlings to grow up, or even rotten dead seedlings.
