Key points of the latest high-yield green bean cultivation technique tutorial
Increasing plant yield is what every grower wants, so what should be done to achieve high yield in green beans? As a common cultivated variety in our country, the key points for increasing green bean yield at present include the following four. Interested green bean growers 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 also differ. Some places are hotter, so correspondingly the seed selection should choose types with a certain heat resistance; some places have an extremely good growing environment, so high-yield types should be chosen. Only in this way is the survival rate of the seedlings correspondingly high, and only then can high yield be achieved. For example, the heat tolerance of Dafang Qingbang bean is relatively outstanding, so southern coastal areas can consider this seedling type; the yield of Guiyang Qingbang bean is relatively high, so the central region can consider this seedling type.
2. Rational fertilization
Green beans need to be fertilized a relatively large number of times. Rational fertilization allows green beans to make the greatest use of fertilizer, which requires growers to grasp the timing well. Base fertilizer is applied together with the seedlings at planting time. About 15 cm after emergence, seedling fertilizer should be added. During the two periods of flowering and pod formation, chemical fertilizer and fruit fertilizer should be added. After one harvest, maintenance fertilizer should be added. In addition to these periods, for some plants whose growth is not very ideal, extra growth fertilizer should be added.
3. Timely seedling setting
When green bean seedlings grow to more than 20 cm, the seedlings should be fixed to the nearby support. If this is late, it will delay the time of pod formation. The support should be tall, and it is best if the top has some branches, so that in the later stage the green bean seedlings will grow relatively densely and have more branches, and naturally form 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, so measures in this regard must be done well to achieve high yield. Brown spot disease and powdery mildew, as common diseases of green beans, are something growers must know how to prevent and treat. The former can be controlled with carbendazim-type anthracnose preparations, and the latter can be controlled with chlorothalonil. Pay more attention to some diseased plants, and it is best to remove the diseased parts and carry them away from the planting area to avoid spread. As for pests such as aphids and ladybugs, as long as they are found in daily management, just crush them directly to avoid spread.
The above are some key points by which green beans can increase yield. The editor thinks that to increase yield, besides sufficient fertilizer, everyone's field management is actually also very important.
