Key points of high-yield techniques of kidney bean

Every grower wants to increase the yield of plants, so what should be done if string beans want to be high-yielding? As a common planting variety in our country, there are four main points to improve the yield of green beans at present. Interested users of green beans can come together with Xiaobian to see what to do.

1. Targeted seed selection

The environment is different in different places, and the seedlings needed are also different. In some places, the relative selection of seeds should have a certain degree of heat resistance; in some places, the growth environment is excellent, so it is necessary to choose high-yield ones. In this way, the survival rate of seedlings is high and high yield can be achieved. For example, the heat dependence of generous green stick bean is relatively prominent, this kind of seedling can be considered in the southern coastal areas; the yield of Guiyang green stick bean is relatively high, and this seedling can be considered in the central region.

2. Rational fertilization

Kidney beans need to be fertilized for a relatively large number of times, reasonable fertilization can make the best use of fertilizer, which requires growers to grasp the time. Base fertilizer should be applied together with seedlings when planting, seedling fertilizer should be added about 15 cm after emergence, chemical fertilizer and fruit fertilizer should be added during the two periods of flowering and pod formation, and conservation fertilizer should be added after a harvest. In addition to these periods, additional growth fertilizer is required for some growth that is not ideal.

3. Timely determination of seedlings

When the seedlings grow to 20 cm, the seedlings should be fixed on the next support, late will delay the time of pods. The support should be high, and it is better to have some branches at the top, so that the seedlings will grow thicker and have more branches in the later stage, and there will naturally be more pods. At this time, the seedlings of the four seasons will receive plenty of sunlight, and the expansion rate of pods will be greatly increased, which is also conducive to picking and harvesting.

4. Prevention of diseases and insect pests

One of the main factors of yield reduction is diseases and insect pests, and measures for high yield must be done well. Brown spot and powdery mildew are common diseases of kidney beans. Growers should know how to prevent and treat them. The former can be prevented by anthrax, while the latter can be prevented by chlorothalonil. For some diseased plants to pay more attention, the disease site had better be removed, take away from the planting area, so as not to spread. Pests such as aphids and ladybugs are directly crushed to death as long as they are found so as not to spread.

These are some of the main points that can increase the yield of string beans. The editor thinks that in addition to adequate fertilizer, everyone's field management is also very important.
