What to do if the beans you planted yourself have lodging

Lodging is a phenomenon caused by external factors and is a permanent dislocation of the plant from its natural upright state to the stem of the plant. Lodging is a common problem in crop production, and has become one of the important limiting factors for high and stable crop yield. Crop lodging can only be natural, not forced.

The following is a detailed introduction to the specific measures to prevent lodging.

1. Select dwarf varieties that are resistant to water and fertilizer, thick stems and short internodes, determine the appropriate planting density, implement scientific fertilizer and water management, cultivate strong seedlings, and prevent and control pests and diseases in a timely manner. If necessary, plant growth regulators.

It can be used to adjust internode length, plant height, plant type, etc. Disease-resistant varieties are selected for planting. If the bean plant falls, do not help it or it will hurt its roots.

2. It is to improve the quality of land preparation and sowing, select medium and low-grade varieties with high yield, fertilizer tolerance and lodging resistance after heavy rain, manually lay the fallen crops in time, remove stagnant water, spray plant growth regulators, and enhance the stress resistance of crops. Drain immediately. Level and cultivate the soil.

Add nitrogen fertilizer or compound fertilizer.

Usage. Do a good job in pest control.

3. Drainage and waterlogging should be carried out immediately, and the fallen crops should be manually lifted in time and sprayed with plant growth regulators to enhance the stress resistance of crops. After lodging, pay attention to drainage when the soil moisture is high. If the lodging occurs early, tall crops should be uprooted as soon as possible and management should be strengthened. For densely planted crops, it mainly relies on stem auxin.

to promote the reverse growth of the lodging stem in a certain node and return to the erect state.

4. It is necessary to scientifically fertilize and use water to prevent excessive nitrogen fertilizer, implement formula balanced fertilization, strictly control the topdressing time, and avoid initial topdressing; Using chemical control technology, paclobutrazol was sprayed on the seedlings.

Plant growth regulators such as Zhuangfeng amine can shorten the length of basal internodes, increase the thickness of stem walls, and improve lodging resistance. Increasing potassium fertilizer at seedling stage can improve the strength of corn stover. In the case of sufficient nitrogen fertilizer, the combined application of potassium fertilizer and nitrogen and potassium fertilizer should be promoted.

Potassium fertilizer should be used as early as possible and applied as a seedling fertilizer after emergence. Soil cultivation can promote the rooting and development of aboveground backbones and improve the lodging resistance of plants, which is one of the effective measures to prevent lodging of maize. Train.

In this case, it may be because of the lack of nutrients in the beans, and at this time, you should water some topdressing in time, so that the lodging situation can be changed.

To water and fertilize in time, soil fertility should also be ensured, do a good job of loosening the soil and killing insects, and prune branches and leaves regularly.

If you water too much and fertilize too much, you should reduce your fertilizer intake and keep it sunny.

Summary. For lodging soybeans, the plants often cover each other, affecting photosynthesis, and must be supported in time after lodging, before the plants have formed new roots, and fertilization should be applied while cultivating the soil to promote the rapid rooting of new roots. 7 10 kg of potassium fertilizer can be applied per mu, which can enhance the lodging resistance.

For the plots that have fallen due to flooding, rush to drain the stagnant water in the field to reduce the flooding time, especially for the plots that have been flooded for less than two weeks, they should be drained in time to restore the vitality <> soybean roots

Hello, yes <>

Lodging has a great impact on soybean yield, the heavier the lodging, the greater the yield reduction, and the earlier the lodging, the more the yield is reduced. The occurrence of soybean lodging is usually caused by the overgrowth of the plant. First, according to the characteristics of planting varieties and local environmental conditions, determine the reasonable planting density and planting method, and the density of plots with good fertility should not be too large; The second is reasonable fertilization, the proportion of nitrogen, phosphorus and potassium is coordinated, and excessive nitrogen fertilizer must be avoided; the third is timely cultivation to promote the development of soybean roots and enhance the ability of soybean to resist lodging; Fourth, according to the local soybean growth, weather trends, etc., plant growth regulators should be applied in a timely manner.

The main function of the regulator is to reduce plant height and internode length, increase stem diameter, and thus enhance soybean lodging resistance.

Soybean is a kind of fine stem crop, planting density is larger, generally per mu (667) planting 8500-10000 plants, in case of wind and rain in summer, it is particularly prone to lodging phenomenon, once lodging, it will cause a reduction in yield or no harvest, is the first major technical problem that has plagued soybean production for many years.

Douge can effectively improve the lodging resistance of soybean, mainly due to the following two points: first, Douge can regulate and control the growth and development of soybean, after the use of soybean in the early flowering period of soybean, Douge can quickly form a control factor in the soybean body, shorten the internode height of soybean 1-3 nodes, make soybean grow slower in the early stage, and promote the soybean stem to become thicker, internode shortening, long stocky, strong, forming a good "figure"; Second, because Douge can promote the development of soybean root system, the number of root nodules is greatly increased, the nutrients are sufficient, and the ability to fix the land is enhanced. Third, because after the soybean podds, the soybean song can quickly promote the lignification of the soybean stem and enhance the hardness of the stem, so that the soybean is not easy to lodging when it encounters wind and rain.

If you ask a farmer who grows soybeans, what is the most troublesome question during the growing of soybeans? I believe that the ultimate answer is not pests and diseases, nor weeds, but lodging, because after the lodging of soybeans, it will more or less lead to a reduction in yield. For particularly severe lodging, there may be no gain.

Regarding the situation of soybean lodging, some can be avoided and some cannot be avoided. It depends on the reason for the lodging. In the following content, we will discuss with you 6 common factors that cause soybean lodging in detail, hoping to get the attention of growers.

Seed issues. Purchased soybean seeds are not good or fake seeds. For example, after sowing some soybeans, due to the seeds, after the emergence of the seedlings, the seedlings become weaker, the seedlings become weaker, the root system is underdeveloped, and the stems are thinner.

In the mid-to-late stages, they experience strong winds and heavy rain. It was very easy to stay. When you need to buy seeds, carefully distinguish between old seeds, undocumented seeds, and seeds that are not grown locally.

It is not recommended to buy them.

Sowing problems. When soybeans are planted, the field density is too high due to the large amount of sowing seeds. After the soybeans emerge, they will be found to be crowded, especially in the middle and late stages, when the leaves are completely sealed, the field ventilation is very poor, and they can block each other.

It affects normal photosynthesis. In addition, competition between plants for water and nutrients can lead to poor growth, fragile seedling growth, and easy lodging.

Prosperity issues. Some farmers find that there is water backing in the field, and they will consider whether it is due to long-term reasons, such as too much fertilizer, which causes soybeans to appear in the field, and cannot control it. The chances of inversion will increase.

Here, soybeans produce rhizobia, and the roots provide some nitrogen, so if planted, there will be too much nitrogen fertilizer.

Pest problems. During the planting process, there are no prevention and control measures. When there are pests in the field, it can also cause soybeans to stand upside down, especially the roots of underground pests, thus destroying soybeans. On the one hand, on the other hand, insecticide sprays or irrigation treatments are used.

Disease problems. It can also lead to the appearance of handstands when soybeans are infected, such as soybean stems. Once infected, it cannot be prevented in time, the soybean stalk is destroyed, and it is easy to break, especially in windy, rainy weather, under the action of the outside world, it is normal to appear.

Weather issues. This cannot be avoided. For example, it is not possible to have heavy rain, hail or other extreme weather. There is no way around this situation. After all, growing agriculture sometimes requires a certain amount of luck.

It is very likely that the plant lacks nutrients, resulting in a weak rhizome. Appropriate amount of nitrogen and potassium fertilizer supplementation to promote the growth of plant rhizomes. It is also possible that the plants are too sparse. It is also possible that the plant has developed pests and diseases.

It may be that the vegetative growth in the early stage is too vigorous, the plants are too dense, and the straw is too fine.

It may be that the plant lacks nutrients, resulting in the lodging state of the plant's rhizome is not hard, or it may be that the plant is not densely planted. The seeds should be evenly sprinkled in fertile nutrient soil at the time of planting.

In the flowering period, if you find that there is a vigorous soybean, you can spray the control agent in bad weather, after the occurrence of strong wind and rain, drain as soon as possible, check the degree of lodging in the field, if it is not too serious, do not go to the artificial straightening, so as not to break the stem, and at the same time wait for sunny days, insecticidal and disease prevention work, you can also spray foliar fertilizer, supplement nutrition, if it is particularly serious, basically wait for the yield to be reduced.
