What should I do if the soybean plant is not tall?

If the soybean plant is not tall, it could be due to a number of reasons. Here are some possible causes and how to fix them:

1.Pest and disease infestation: Soybeans may be attacked by some pests and diseases, such as aphids, rust, etc. The solution is to detect and control with appropriate pesticides in a timely manner.

2.Poor soil: If there are not enough nutrients in the soil, soybean plants may grow slowly. The solution is to apply the right amount of organic fertilizer or chemical fertilizer to provide the nutrients that the plant needs.

3.Insufficient water: Soybeans need adequate water to grow properly. If the soil is dry, the plant may become dwarfed. The solution is to irrigate or water in time to ensure that the plants get enough water.

4.Temperature discomfort: Soybeans are plants that prefer warm climates, and if the temperature is too low or too high, it may affect its growth. The solution is to ensure that the growing environment is at the right temperature and take appropriate measures to protect the plants.

In short, to solve the problem of low soybean plants, it is necessary to find out the specific cause and take corresponding measures. If more specialized advice is needed, it is best to consult an agricultural specialist or plant doctor.

However, if the growth of soybeans becomes slow, or the leaves become weak, it means that there is a problem with the growth of soybeans, and the nutrients in the soil can not meet their growth well.

Summary. Hello, artificially sharpened, suitable for friends with less land, in the prosperous plot, the leaves are sharpened, and the tips can not be played at will. Pesticide prevention and control, this is a commonly used method, like other crops, the prevention and control agent can choose paclobutrazol, pay attention to the dosage, do not increase the dosage privately, apply according to the dosage instructions, in addition, in the fight to control the prosperity.

There are too many drugs to control Wangchang.

It is recommended that the vegetable farmer first remove all the small melons on the top of the plant, leaving only one melon on each plant, so as to reduce the burden of the plant and promote its recovery as soon as possible. In addition, the whole shed is sprayed with Yunda 120 mixed with amino acids or seaweed Jane Hushen acid foliar fertilizer, raising the head to promote the tree, once in about 5 days, spraying 2 times in a row.

How to relieve the drug damage.

Spray growth regulators or foliar fertilizers as soon as possible to relieve damage.

The soybean plant is not tall and does not need to be multi-effected.

The role and method of soybean control:

First, the role of soybean control.

Soybean is very prone to the problem of vigorous plant growth at the flowering and podding stages, and if it is not controlled in time, it is prone to problems such as field lodging, poor disease resistance, and decreased photosynthesis.

Second, judge the vigorous growth of soybeans.

1. Leaf growth.

The soybean leaves are vigorous, and the air permeability of the cluster chain is poor, and the field is completely closed.

2. Leaf color.

From the outside, the upper leaves of the soybeans are dark green in color and have a large area, while the lower leaves have turned yellow and some have begun to fall off.

3. The number of inflorescences.

If there are only a small number of inflorescences in the upper part of the main stem, and there are few inflorescences in the branches, the lower part of the main stem, etc., this is also a manifestation of vigorous growth.

In general, to judge whether soybeans are vigorous, you can observe from the above three aspects, if there are the above three situations, you can not let soybeans grow freely, you need to control the prosperity, and generally control the pesticides. The small planting area can also be artificially controlled, mainly by tipping and topping.

3. Soybean control method.

1. Spraying time.

When soybeans are in full bloom, they are generally carried out at the first flowering stage or the full flowering stage. In years with more rain, after the rain, the plants will grow rapidly, and the plots with a tendency to be closed in advance and grow can also be sprayed with a growth control agent after the rain to prevent growth.

2. Spraying selection.

Commonly used control agents such as paclobutrazol, uniconazole, chlormequatin, and arthrochlor are commonly used.

3. Spraying method.

1) paclobutrazol: in the first flowering stage of spring soybean and the full flowering stage of autumn soybean, spray with 60 grams of 15% paclobutrazol wettable powder mixed with 50 kg of water per mu. It can make the plant compact, prevent vigorous growth and lodging, and can effectively increase the number of beans and grain weight.

2) Uniconazole: At the first flowering stage of soybean, 30 grams of 5% uniconazole wettable powder per mu, 30 kg of water are added, and then sprayed. It can reduce plant height, control elongation, promote the growth of side buds and flower bud formation, and enhance stress resistance.

3) Chlormequatin: Chlorquat is mainly used to control growth. The spraying period is the full flowering period, the concentration is 500-1000 mg kg, after spraying, the stalk can be thick, increase the lodging resistance to rock seepage, and also increase the number of soybean pods.

4) Arthroamine: When soybean grows to full flowering, 5-6 grams of arthroamine can be used per mu, mixed with 15 kg of water, and then foliar spray is carried out. It can adjust the internode growth of soybean, dwarf plant height and shape good plant shape.

There are mainly the following 5 measures: 1. Sowing science. Spring soybeans are sown between late April and early May, and summer soybeans are sown in mid to late June after wheat harvest. The sowing density is determined according to the plant type and soil fertility, if the plant shape is small and the soil is trapped and the soil is fertile, it can be about 20,000 plants per mu, and if the plant type is large and the soil fertility is average, it can be 10,000 plants per mu.

2. Choose good breeds. It is necessary to choose excellent varieties suitable for local planting, avoid excessive pursuit of new varieties of royal ruler brothers, do not buy varieties that have not been planted, and in addition, choose varieties with strong resistance to stress, which is also relatively beneficial to later growth. 3. Reasonable fertilization.

Soybean fertilization should follow the "suitable nitrogen fertilizer, increase organic fertilizer, with phosphorus and potassium fertilizer and micro fertilizer", carefully apply nitrogen fertilizer, and spray trace element fertilizer in the middle and late stages, which can effectively prevent the flower pod from falling off. 4. Reasonable irrigation. Irrigation should be carried out in time to prevent severe drought and affect the growth of soybeans.

In addition, in summer, when it is rainy weather, it is necessary to pay attention to the prevention of waterlogging in the field and timely drainage. 5. Pest control. Soybean pests and diseases should be prevented and controlled in time, commonly used pesticides are cypermethrin, chlorpyrifos, etc., and downy mildew, which can be treated with methyl frost, manganese zinc, chlorothalonil, etc.

It is a herbicide pesticide that damages the stove. Solution or roll to save the prescription to prepare the skin: spray the plants with 600 times Tianda 2116 Zhuangmiao Ling Liquid + 200 times Brown Sugar Solution + 500 Times Urea Solution + 6000 Times 99% Tianda Evil Moldy Liquid + 3000 Times Tianda Organic Silicone Solution, once every 7 days, spraying 2 times in a row, which can effectively rescue soybean herbicide damage.
