High protein soybean cultivation techniques

Our province is one of the major producing provinces of high-yield soybeans in summer. Due to the non-standard cultivation techniques, the mu yield of soybean in our province has been low for many years, affecting the income of farmers. Now we introduce the cultivation techniques of high-protein soybeans as follows for reference.

Land selection and fertilization. Because of the 20%-30% output reduction of heavy soybean crops, it is best to choose high-protein soybeans that have no pollution, fertile soil, sufficient water resources, and no heavy crops. When planting Mushi manure more than 1,000 kilograms, evenly before the site preparation. The ratio of nitrogen fertilizer, phosphate fertilizer and potash fertilizer is 1:2:1 when chemical fertilizer is applied. In general, 13 kg of ammonium phosphate and 5 kg of potassium sulfate are applied per acre, and the seed is applied in layers.

Seed dressing. Soybean inoculation of Rhizobium before sowing is an effective measure to increase production. The specific method is: use a small amount of rice soup or water into the paste into the paste into the seeds, and then put the seeds in the shade, slightly dry and then mix in phosphate fertilizer and potash, or add a small amount of molybdenum fertilizer, boron fertilizer, manganese fertilizer Trace elements such as fertilizer, and immediately after sowing.

In addition to. Each acre with 50% acetochlor 130 ml plus 48% Guangmiaoling 50 ml water 25 kg, immediately after sowing soybeans for pre-emergence soil treatment.

Cultivator. The cultivator has a variety of functions, such as breaking the compaction, storing water, protecting the weeds, eliminating the weeds, promoting the survival of rhizobia and enhancing the nitrogen fixation ability of the rhizobia. The cultivator should be cultivated 3 times according to the standard of "shallow, deep and shallow". The last cultivator should also be earth-cultivated to prevent the lodging of plants.

Drought prevention and drainage. From the flowering stage to the grain-filling stage, high-protein soybean has the fastest water-absorbing rate and the largest amount of water consumption. If the soil moisture is less than 25%, the phenomenon of flowering and falling will occur. Irrigation should master the principle of pouring small water and avoid flooding. Generally, it is poured once every 5-7 days, and it is poured 2-3 times in succession to protect the flowers and increase the yield and quality. In addition, soybeans are a kind of poorly-tolerant crops. After flooding, they are easy to fall and fall. Therefore, attention should be paid to trenching and draining to prevent waterlogging.

top dressing. Soybean topdressing nitrogen fertilizer at the end of the scab can meet the nutrient requirements of soybean grains, but it will not cause plant growth, and it will help increase grain weight and yield. For the general plot, the ditch can be created during the flowering period, and about 10 kilograms of urea can be applied per acre, and the fertilizer can also be applied to the soybeans in combination with irrigation. If the fertilizer is insufficient, extra-root fertilizer should be applied during the grain period. Generally, 0.5 kg of urea, 1.5 kg of superphosphate, 0.25 kg of potassium sulfate are added per acre, and 50 kg of water is added to the leaves after being dissolved, preferably on a cloudy or sunny day. Spray after 4 pm, heavy rain should be used in case of rain.

Timely harvest. Shake the soybean plants and harvest them when there are sounds of the grains shaking and about 10% of the leaves of the plants do not fall. Grasping the harvest period is beneficial to improving the yield and quality of soybeans.
