Technology of promoting early ripening of soybean

Soybean is one of the main crops in China, and in the process of planting soybean, many farmers hope that their soybeans can mature quickly, but there is no good way, if the method is used wrong, it may also cause pulling seedlings to encourage. The following editor will explain the methods of promoting early maturity of soybeans for you. Let's take a look.

1. Drainage to promote growth

From July to August, many areas are in the rainy season with heavy rainfall. Too much Rain Water will affect soybean in varying degrees, especially in low-lying land, which is easy to rett root, which seriously affects the quality and yield of soybean. Therefore, for the low-lying terrain prone to waterlogging, drainage treatment should be carried out in time, and measures such as mechanical drainage and trenching drainage can be taken to eliminate stagnant water in the field and stagnant water in the plough layer in time. In addition, straighten up in time after drainage, cultivate plants and wash away the silt on the surface to promote the normal growth of soybeans as soon as possible.

2. Smoke and prevent early frost

To pay close attention to climate change, after entering the autumn, the temperature drops, especially at night, at 2: 00 to 3: 00 in the morning. When the temperature drops to 1-2 degrees, the method of artificial smoking can be adopted to prevent early frost. In the upwind of immature soybean plots, straw and weeds can be ignited and burned slowly, so that the land will form a layer of smoke, which can increase the surface temperature by 1-2 degrees, improve the field microclimate and reduce the harm caused by frost. Smoke should be distributed closely and evenly, and smoke should be shrouded in the whole field as far as possible. in addition, red phosphorus and other chemicals are used to burn in the field, which also has the effect of frost prevention.

3. Spraying fertilizer to promote early ripening

Spraying foliar fertilizer at the flowering and pod stage of soybean can accelerate the growth and development of soybean and promote its early maturity. generally, the foliar fertilizer sprayed is urea potassium dihydrogen phosphate, 350-700 grams of urea plus 150-300 grams of potassium dihydrogen phosphate per mu. If the soil is deficient, the corresponding micro-fertilizer can be used in the field. Foliar fertilizer spraying time is generally after 4 o'clock in the afternoon, try to avoid the high temperature period, in order to avoid drug damage, in the whole flowering and pod period of soybean can be sprayed 2-3 times. It can also be sprayed with growth regulators such as brassin and dwarftin, which can not only provide a portion for the plant, but also effectively increase the stress resistance and cold resistance of the plant. In addition, timely pulling out weeds and increasing the permeability of the field can also promote the early maturity of soybean.
