This year's beans have a good market, and the price is still above 2 yuan per catty. Many vegetable farmers only have eyebrows, because many beans are difficult to sit on, even if they are sitting only some defective products, it is not worth the money.

On September 5th, the reporter came to Dongxia Town in Qingzhou City and met Master Zhang Huaqing who was preparing to sell beans. He was tying the beans that he had picked off at the edge of the shed. The reporter saw Master Zhang Huaqing's bean pods uniform in length, green in color, and picked 300 jins at a time. The reporter can not help but praise: Your beans can have such a high yield, and the quality is still so good, it seems that you really have two ways to grow beans.

After talking with Master Zhang, the reporter felt that Master Zhang really had some worthwhile experience in managing.

First, make timely plant adjustments. The side branches below the first inflorescence of the main vine were removed, ie, the side branches on the first inflorescence above the main vine, leaving 1-3 leaves topping, retaining the inflorescences on the side branches, and increasing the crusted part. When the main vine grows to a height of 2-2.3 meters, the buds on the top leave a leaf topping, picking up the heart, promoting the formation and development of the lower node flower buds, preventing the main vines from growing too long, intertwining in the racks, not ventilating and ventilating, and not conducive to Pick beans.

Second, turn off the good temperature and raise the leaves and vines. The temperature difference between day and night should be strictly controlled, beans heat resistance, suitable for the growth temperature of 25 °C -28 °C. The optimum growth temperature during the flowering period of beans is not to exceed 35°C during the day and 18°C ​​during the night, which increases the temperature difference between day and night. Therefore, we must strictly control the temperature and change the air release time as the outside temperature changes. In addition, if there is poor ventilation and light transmission at the bottom of the plant during production, it is easy to cause fall and fall in the late stage. The old leaves in the lower part can be cut off and the defoliation in the field can be eliminated.

In addition, grasp the key period of make-up water. The period of flowering and podging of bean was longer. After the first peak of yield, the growth of plants was weakened. Therefore, in the 5-7 days before flowering, timely application of 15-20 kilograms of compound fertilizer + 10 kilograms of superphosphate + 5 kilograms of potassium fertilizer can promote flowering and scarring. During the prosperous period of soybean meal growth, fertilizer should be topped once again, and 15-25 kg compound fertilizer should be applied. After the flood season, according to the growth of the plants, a certain amount of total water-soluble fertilizers can be applied to extend the harvest period and increase the yield of beans.
