Planting techniques of beans in open field in spring

The temperature gradually rises in spring, when the humidity and moisture are also more abundant, it is a good season to grow vegetables in the open field, and beans are no exception, can be cultivated in the open field. So how to grow beans in the open field in spring? Let's get to know it with the editor.

1. Cultivation time

Open field cultivation in spring is the main cultivation method of beans, which is mainly used in most parts of the country. This method has the largest planting area, the highest yield, the long harvest and supply time, and the largest yield. In North China, the seeds are generally sown in the open field from the final frost period to the middle of April. After emergence, the final frost period has passed, and the seedlings can grow safely. Young pods can be harvested in mid-June, and generally harvested until mid-late August.

2. Preparation for sowing

Open field cultivation of beans in spring, mostly choose winter fallow land or rice stubble after overwintering leafy vegetable harvest, and after the previous crop harvest, clean up the field in time, ploughing the land, making the soil layer loose. 10-15 days before sowing, fully rotten organic fertilizer is applied as base fertilizer, and the amount of fertilizer can be determined according to local conditions and according to soil quality and fertility. Generally, 5000-6000 kg of organic fertilizer and 50-100kg of compound fertilizer are applied per mu, and shallow ploughing is done once. After mixing the soil and fertilizer, the beds are leveled. In areas with more Rain Water, drainage channels should be built so that they can be drained after rain.

3. Sowing method

Planting beans in open field in spring, if sowing directly, can be carried out 5-7 days before the final frost period, and the soil temperature of 10 cm above 10 degrees. It is necessary to ensure that there is no frost harm after the seedlings are unearthed. When sowing, if the soil water content is suitable and the soil moisture is good, you can not water it, open a ditch for direct seeding, if the soil is dry, you can first open a ditch for watering, and if sowing and watering, close the ditch. When raising seedlings and transplanting, we can first open ditches to plant seedlings, and then water them to cover the soil to seal the ditches, and the cultivation density varies with different varieties.

4. Field management

The temperature in early spring is low, and after sowing beans, the seedlings often emerge slowly and unevenly, and the phenomenon of missing seedlings and broken ridges often occurs, and the phenomenon of dead seedlings often occurs during seedling raising and transplanting, so it is necessary to check seedlings and replenish seedlings in time. Bean seedling stage, should be late ploughing weeding, squatting seedlings, promote root growth, in the case of sufficient soil moisture, the seedling stage is generally not watered, when the seedlings are complete, later combined with watering, timely ploughing and hoeing. Topdressing is mainly nitrogen fertilizer, about 10 kg of available nitrogen fertilizer per mu. If you apply organic fertilizer, you can spread it between rows or open a shallow ditch, row it once after application, mix the soil and fertilizer, and then water it to promote the growth of stems.
