Should Latest Yardlong Beans Be Pinched? Pinching Methods for Yardlong Beans

The most common vegetable in summer is the yardlong bean. Many people buy some, and besides eating them fresh, they can also be made into pickled yardlong beans and dried yardlong beans. For vegetable farmers, this is also the harvest season; usually before one crop is fully harvested, the next crop is already ripe. But to achieve high yields of yardlong beans, pinching the yardlong beans is extremely important. So how should yardlong beans be pinched? Let's take a look together.

1. Should yardlong beans be pinched?

Pinching yardlong beans is actually removing the top, mainly removing the apical growing point. Simply put, it means picking off the topmost part of the yardlong bean vine. Whether or not to pinch yardlong beans depends on the variety. If it is a bush yardlong bean, pinching is not needed; on the contrary, pole yardlong beans must be pinched, as only this way can the yield and quality of the yardlong beans be improved. Summer is hot and rainy, and both temperature and humidity are suitable for the growth of yardlong beans. If the vine growth is not inhibited in time, it will lead to a lack of nutrients in the yardlong beans and result in low yields. Therefore, pinching at the right time can improve yield and quality.

2. Pinching methods

The method of pinching yardlong beans is actually quite simple. When planting on a large scale, the method of pruning and pinching can be adopted: remove all lateral buds below the first inflorescence of the main stem, which concentrates nutrients on the main vine and ensures the growth of the main vine. For lateral branches at each node above the first inflorescence of the main stem, pinch off the growing tips after retaining 2-3 leaves, which can promote the development of the first inflorescence. When the main vine grows to 2-3 m, the foremost tip of the main vine must also be cut off, which allows the previously retained lateral branches to grow stronger. If the lateral branches develop too vigorously, they still need to be handled. Only through such continuous handling can the yardlong beans be ensured to grow large and long.

3. The principle of pinching for high yield

The yardlong bean is a herbaceous vine with a spreading growth habit. To ensure that nutrients are fully supplied to the pods, the endless spreading of the vines must be inhibited, as only this way can the harvest period of the yardlong beans be extended and a high yield be obtained. What needs attention is that pinching depends on the variety type of the yardlong bean and the planting method. Generally, as long as the yardlong beans are trellised, pinching must be carried out. Some varieties do not need trellising, and generally these varieties do not need pinching either.
