Detailed Explanation of Key Techniques for High-Yield Cultivation of Green Beans

Every grower wants to increase plant yields, so how can you achieve high yields with green beans? As a common crop variety in our country, there are currently four key points for increasing green bean yields. Those interested in green beans can take a look with the editor at what should be done.

1. Targeted seed selection

Environments differ from place to place, and the seedlings needed differ as well. Some places are hotter, so relatively speaking, seeds with a certain heat tolerance should be chosen; some places have extremely good growing conditions, so high-yield varieties should be chosen. Only in this way will the corresponding seedling survival rate be high and high yields be possible. For example, Dafang Qingbang beans have relatively outstanding heat tolerance, so southern coastal areas can consider this seedling; Guiyang Qingbang beans have relatively high yields, so the central region can consider this seedling.

2. Rational fertilization

Green beans need to be fertilized relatively many times. Rational fertilization allows green beans to make the greatest use of fertilizer, which requires growers to grasp the timing well. Base fertilizer should be applied together with the seedlings at planting time. When the seedlings reach about 15 cm after emergence, seedling fertilizer should be added. During the two periods of flowering and pod setting, chemical fertilizer and fruit fertilizer should be added. After one harvest, maintenance fertilizer should be added. In addition to these periods, for those growing not very ideally, additional growth fertilizer should be applied.

3. Timely seedling fixing

When green bean seedlings grow to 20 cm, the seedlings should be fixed to the support beside them. If this is delayed, it will delay the time of pod setting. The support should be tall, and it is best to have some branches at the top, so that later the green bean seedlings will grow more densely and have more branches, and naturally set more pods. At this time, the green bean seedlings will also receive more sufficient sunlight, the expansion rate of the pods will be greatly increased, and it will also be beneficial for picking and harvesting.

4. Pest and disease prevention

One of the main factors reducing yield is pests and diseases. Measures in this regard must be done well to achieve high yields. Brown spot disease and powdery mildew are common diseases of green beans, and growers need to know how to prevent and treat them. The former can be controlled with carbendazim, and the latter can be controlled with chlorothalonil. Pay more attention to some diseased plants. It is best to remove the diseased parts and take them away from the planting area to avoid spreading. As for pests such as aphids and ladybugs, as long as they are found in daily management, crush them directly to avoid spreading.

The above are some key points for increasing green bean yields. The editor thinks that to increase yields, in addition to sufficient fertilizer, everyone's field management is actually also very important.
