Detailed explanation of techniques for seedlings of green beans

Green beans are a common vegetable variety in our lives, and farmers who grow green beans have not been a minority. Friends who have planted green beans should know that green beans want high-yield and high-quality, and seedlings are the first step! So, how do you raise seedlings for green beans? In order to plant early and harvest early, you can use nutritious seedlings. The following Hui Nongwang Xiaobian will tell you about the detailed technology of the bean seedlings.

1. Nursery soil and fertilizer

The regeneration ability of the roots of the green beans is weak, and the seedlings are cultivated with nutrient mash, which can ensure the survival rate at the time of transplantation and reduce the degree of root damage. The nutrient soil used for seedling cultivation should use soil with high organic matter content and strictly control the amount of quick-acting nitrogen fertilizer. It is best to use fertile large field soil instead of the soil of the vegetable garden to avoid the damage caused by the soil with pests and diseases. The organic fertilizer of the nutrient soil should be fully fermented and decomposed. The main raw materials are horse manure, cow dung or simmered compost, etc., and bio-organic fertilizer can be used conditionally.

The preparation ratio of peat soil and nutrient soil is: 60% of field fine soil, 30% of decomposed organic matter, peat soil or bio-organic fertilizer, and others such as super-calcium phosphate, grass ash, and ash after sieving 10%. If you use the high-quality bio-organic fertilizer to raise seedlings, the ratio of soil to fertilizer can be half, and you don't have to add other fertilizers. If you do not use nutrient sputum and raise seedlings directly in the seedbed, you can deepen the bed soil for a few days, spread the fertilizer, and then plan it again.

2, sowing

If seedlings are grown in a nutrient bowl, they should be planted in the morning in sunny weather. Before the sowing, the bottom water should be poured before the water is infiltrated. 2-4 seeds were spotted in each nutrient bowl, and 2-3 cm of soil was planted after sowing. Then the seedling tray was moved to a greenhouse or plastic greenhouse for heat preservation and seedling. If the outside temperature is low, cover the grass and keep warm at night. The seeds of the germinated green beans are 2-3 kg per mu, and the dwarf green beans are 2.5-4 kg per mu.

3, temperature management

Before sowing, the temperature of the green beans should be kept at 25-35 °C during the day, and not more than 15 °C at night. After the seedlings are unearthed, the daytime temperature can be appropriately lowered and kept at 20-25 °C. After 20-30 days, the seedlings can be transplanted and planted when there are 2-4 true leaves. 3-5 days before the planting of the green beans, the daytime temperature can be reduced to about 15 °C, and kept at 10 °C or more at night, and the seedlings can be exercised to enhance the adaptability of the seedlings.

4, water management

In the seedling stage of green beans, if the seedlings are not excessively dry, they may not be watered. For example, if the climate is dry, spray small water, or spread the soil between the plants to protect the soil. Avoid flooding with large water to prevent the soil temperature from being lowered by pouring cold water, and the phenomenon of "rust roots" in seedlings occurs.

The above is a detailed explanation of the technology of the seedlings of the green beans. The former growers usually use the method of first soaking and germination, sowing after sprouting, or the method of dry seeding. Although this method saves labor and labor, it has a slow emergence and a low emergence rate. In the future, you can try the method of raising seedlings of green beans. Not only can you harvest in advance, but the seedlings that grow out are still strong.
