A course on the latest techniques and methods of raising seedlings of beans

Bean is a common vegetable in our life. There are two ways of direct seeding and seedling transplanting when planting, and seedling transplanting is mostly used when planting, which can not only sow, harvest and supply the market early, but also ensure the whole seedling and promote flowering and pod production. So how to raise beans? Let's get to know each other.

1. Soaking seeds to accelerate germination

Select large and full seeds without moth moth and disease spots, first dry for 1-2 days, soak the seeds with appropriate concentration of formalin for 20 minutes, take them out, rinse with clean water and sow the seeds. Or blanch seeds with warm water of about 50-55 degrees for 15-30 minutes, stir continuously in the process of releasing water, until the water temperature drops to 30 degrees, and soak for 6-8 hours. To improve this treatment, not only the germination rate of sowing is high, but also can effectively prevent diseases and insect pests and reduce the incidence of diseases and insect pests.

2. Sowing and raising seedlings

Spring sowing is suitable for late February to March, direct seeding is suitable for late April, and autumn sowing is generally sown in July, because it is in a hot and hot season and can be covered with a sunshade net. After sowing, plastic film should be covered, heat preservation and moisturizing, to facilitate seedling emergence, generally 4 days after emergence, plastic film should be opened in time after emergence, if planting in arch shed, day and night cover should be opened, ventilation and heat preservation should be paid attention to. When sowing in the open field, the plot should be thoroughly watered first, and then sown. Remember that it is more blindfoliated after sowing, and it can be planted before the first real leaves or the first compound leaves of seedlings are unfolded.

3. Soil preparation and fertilization

Beans are not resistant to waterlogging and should not be planted in low-lying, wet and waterlogged land. Before sowing, the land should be ploughed deeply and combined with mature organic fertilizer 2000-4000 kg per mu, calcium superphosphate 15-20 kg, plant ash 100,150kg, or microbial fertilizer 150,200kg as base fertilizer. After the cultivated land will be raked flat, good cultivation border, generally according to the width of the border 1.7m, ditch depth of 20-30cm in spring, 15-20cm in summer and autumn, and then covered with plastic film.

4. Reasonable close planting

In order to obtain more yield of beans, reasonable close planting must be carried out, which is the most important thing, especially after emergence, when the emergence is not high, the seedlings should be replenished in time, and the seedlings should be fixed 5 days after emergence, so that the root cutting can be reduced and the survival rate of seedling transfer can be improved. Be careful not to touch the rhizome and affect the normal survival rate when intersprouting.
