The Latest Technical Method Tutorial for Promoting Early Maturity in Soybeans

Soybean is one of the main crops grown in China, and during the soybean cultivation process, many farmer friends hope their soybeans can mature faster, but they are troubled by the lack of a good method. If the wrong method is used, it may even lead to pulling up seedlings to help them grow. Below, the editor will explain the methods for promoting early maturity in soybeans. Let's take a look together.

1. Drainage to promote growth

In July-August, many regions are in the rainy season, with relatively high rainfall. Excessive rain can affect soybeans to varying degrees, especially in low-lying plots, where root rot is very likely to occur, seriously affecting soybean quality and yield. Therefore, for low-lying areas prone to waterlogging, timely drainage and waterlogging reduction treatment should be carried out. Measures such as mechanical drainage and ditch digging for drainage can be adopted to promptly remove accumulated water in the field and perched water in the plow layer. In addition, after drainage, promptly straighten and cultivate the plants, wash away the surface silt, and promote soybeans to return to normal growth as soon as possible.

2. Smoking to prevent early frost

Pay close attention to climate changes. After entering autumn, temperatures drop, especially at night when the temperature is relatively low, around 2-3 o'clock in the morning. When the temperature drops to the crop critical point of 1-2 degrees, artificial smoking can be used to prevent early frost. At the upper air vent of immature soybean plots, straw and weeds can be ignited and allowed to burn slowly, so that a layer of smoke forms over the plot. This can raise the surface temperature by 1-2 degrees, greatly improve the field microclimate, and reduce the harm caused by frost. The smoking points should be evenly distributed to ensure the entire field is covered by smoke as much as possible. In addition, burning agents such as red phosphorus in the field also has a frost prevention effect.

3. Spraying fertilizer to promote early maturity

Spraying foliar fertilizer during the soybean flowering and podding stage can accelerate soybean growth and development and promote early maturity. Generally, the foliar fertilizer sprayed is urea plus potassium dihydrogen phosphate. Per mu, 350-700 grams of urea plus 150-300 grams of potassium dihydrogen phosphate can be used. If the soil lacks certain elements, the corresponding micro-fertilizer can be applied in the field. The spraying time for foliar fertilizer is generally after 4 p.m., avoiding high-temperature periods as much as possible to prevent phytotoxicity. During the entire soybean flowering and podding stage, it can be sprayed 2-3 times. If conditions permit, growth regulators such as brassinolide and chlormequat can also be sprayed, which can not only provide the plants with a share of nutrients, but also effectively increase the plants' stress resistance and cold resistance. In addition, promptly pulling out weeds and increasing field ventilation and light penetration can also promote early maturity in soybeans.
