Beans are annual vegetables, which are very popular among the public, both in terms of nutritional value and taste. Beans are also one of the most widely cultivated vegetables in our country. Especially in rural areas, each household will basically plant one or two plots to ensure the self-supply of vegetables. Then, in the process of planting beans, if you want high yield, how should you manage the fertilizer and water? Let's explain the high-yield fertilizer management skills of the beans.
First, the type of high-yield fertilization of beans
Base fertilizer
If you want to produce high-yield beans, you must apply the base fertilizer. The base fertilizer is mainly composed of decomposed organic fertilizer and compound fertilizer. The base fertilizer can be applied when the beans are fine and ridged, and a small ditch can be opened on the planting ridge, and then the bottom fertilizer is placed in the ditch to cover the soil. However, it should be remembered that the distance between the bean seedlings and the organic fertilizer ditch should be kept at a distance of about 10 cm, so as to avoid burning the roots of the bean seedlings.
2. Top dressing
If the base fertilizer is sufficient, the first top dressing can be extended to the vine season. If the fertilizer is lacking, the first leaf of the bean plant can be raised to the vine before the vine is applied. It is necessary to reapply the top dress when the beans are flowering and podging.
3. Foliar fertilizer
In the middle and late growth stages, the bean cultivars often show symptoms of deficiency of trace elements such as leaf yellow, so the seedling stage and the vine-growing stage of the beans are sprayed with foliar fertilizer.
Second, beans high-yield fertilizer management skills
1. If the bean fertilizer is sufficient to apply the base fertilizer, it can promote the root growth of the beans and the activity of the rhizobium, so that the early stems grow robustly. The base fertilizer is generally applied with 2000-3000 kg of high-quality organic fertilizer per acre, 25-30 kg of superphosphate, and 50 kg of ash.
2. Before the flowering and pod formation, the management of water and fertilizer is mainly controlled. If the base fertilizer is sufficient, it is generally no longer topdressing. When the weather is dry, it can be properly watered. When the inflorescence pods of the bean plants sit and the subsequent inflorescences appear, the water can be poured once with the top dressing.
3. After the bean leaves enter the result period, it is necessary to carry out a top dressing and watering every half month or so. During the harvest period of entering the pods, the beans need more water and fertilizer, and another irrigation and topdressing can be carried out.
The above is the introduction of the types of high-yield fertilization of beans and the management of fertilizer and water. Fertilizer and water have a great influence on the life of the bean plants. The growers should ensure that the fertilizers in the process of growing beans are sufficient.
