1. Select improved varieties
Now there are many varieties of beans, including red-skinned beans, local beans and hybrid beans, etc. We can select seeds according to various planting conditions in our locality. Generally, we can choose two or three varieties with the highest cost performance for mixed planting at one time, which can improve the yield of beans to a certain extent, and at the same time, new varieties of beans will appear to improve the quality of beans.
2. Soil preparation and sowing
If it is only for your own consumption, there is no requirement for soil preparation. However, if you want to achieve high yield, it is best to choose land with fertile soil and not easy to accumulate water, and combine it with base fertilizer for deep ploughing. The base fertilizer is mainly soil manure or livestock manure, with an average of about 3, kilograms per mu. Nowadays, beans can be sown all year round, but the best yield and quality are sown in April. Before sowing, we can sun the seeds for two days, then soak them in warm water for 24 hours, and finally take them out and soak them in medicine, so that chickens can promote the germination speed and enhance the resistance of plants. After the seeds are treated, we can sow them by drilling or hole sowing, evenly sow the seeds according to the row spacing of 4 cm and the plant spacing of 3 cm, and then cover the seeds with soil.
3. Water and fertilizer management
When the bean seedlings grow to about four or five centimeters, we need to water them so that they have enough time to grow. Secondly, when the bean seedlings grow to about twenty centimeters, we need to carry out the first intertillage weeding and combine it with fertilization. This fertilization can be carried out by mixing manure water with about 3 kilograms of urea. Then we have to wait until the flowering time to fertilize. At that time, we mainly sprayed potassium fertilizer and phosphorus fertilizer. The most important thing is fertilization after harvesting, which can prevent the bean seedlings from aging, so as to grow new branches and leaves, and blossom and bear pods, which is why other people's pods are inexhaustible.
4. Scaffolding and coring
Scaffolding is a very important step to increase the yield of beans. If you don't scaffolding and let them crawl and grow on the ground, basically you won't see any beans, so we usually start scaffolding when the bean seedlings grow to about 3 cm, and we have to manually lift them up, because it is impossible to actively grow along the scaffolding. Secondly, there is another way to increase the yield of beans, that is, when the Doudou bean seedling grows to about 6 cm, we need to remove the heart of its main seedling, then it will grow lateral branches, and then repeat the same action in turn until it feels appropriate.
5. Picking leaves and thinning flowers
Another way to improve the yield of beans is to gently pick some thin flowers and flowers damaged by pests in the full bloom period of beans, which can reduce the loss of nutrients and prevent the phenomenon of falling flowers, so as to minimize the loss. Finally, when the beans are formed, we need to remove some of the surrounding leaves, so that the beans can carry out full photosynthesis, enhance the permeability of the field, and at the same time reduce the loss of nutrients and water.
