1. Soil conditions with high soybean yield Soil conditions are the basis for high soybean yield. Soil moisture status, nutrient status, and soil physical properties are important factors affecting soybean yield.
Germination of soybean seeds requires more water than cereals. Soybean roots are softer and have higher moisture content. The proper soil moisture conditions can promote the deep root elongation. The main root of the plant can reach about 1 meter, and the lateral root can extend parallel to 0.5 meters. Insufficient soil moisture will affect its vertical and horizontal extension.
Soybean roots are sensitive to changes in oxygen in the soil. In the absence of oxygen, the amount of root growth was significantly reduced. Therefore, moderate soil moisture content, deep plowing layer and moderate elasticity can provide good moisture content and ventilation conditions, which will promote root growth and development. In soil science, soil compaction is used as the physical property index of soil moisture and aeration, and it is generally expressed as weight (grams per cubic centimeter of dry soil). The suitable soil capacity for soybean is 1.0 to 1.4. Loam is most suitable for the growth of soybeans, clay soil, clay loam soil and sandy loam can also grow normally; sand and clay, weak water holding capacity or poor ventilation are not conducive to growth.
2. Soil preparation Techniques for planting soybeans include flat-turning, ridge-planting, hoeing and deep-sowning techniques.
(1) Ping Fan Duo is applied in the spring soybean area which is cooked once a year in the north. Through ploughing, accelerated soil ripening is conducive to the full use of nutrients. To create a certain depth of loose plough layers, to bury agricultural fertilizers, residues, pests, weeds, etc., in order to improve the quality of sowing and create conditions for emergence.
Land-turning time varies depending on the pre-production, and sometimes it is subject to change due to weather conditions. The wheat maggots should be rolled over in August and should be completed in August, but no later than the beginning of September. Black soil depth of 25 to 35 centimeters; loess, white soil, light alkaline soil or thin or substratum soil containing harmful substances deeper than the fertilizer layer. After the ambush, in the autumn, after the soil has fully accepted the rainwater, it will be fine and smooth. Corn sorghum, millet sorghum and sorghum are turned autumn. The autumn fall time is short. Once it is rainy, it cannot be carried out. It can only be turned in the spring of the following year. The fall should end before freezing and can reach a depth of 20-25 cm. The fall-turning land should be ploughed immediately after ploughing, and once again be leveled and repressed before spring sowing the next year to prevent running crickets. The spring turns should be carried out before the soil is returned to the soil. A suitable depth of 15 cm is appropriate.
In general, the cumulation is better than the autumnal turn, which is beneficial to the accumulation of rainwater; the autumn turn is better than the spring turns, preventing excessive loss of water before spring sowing. However, if the fall is uncomfortable, the water will be too much, forming a large clod, the effect is not as good as the spring turn.
(2) Ridge cultivation is a commonly used traditional farming method in Northeast China; after ploughing, it can be used for ridges, which can increase the temperature, deepen the cultivation layer, and increase the drought resistance of the drainage. Before being used as corn, sorghum or millet, the original ridges were used for winter and before thawing in the early spring, the rakes were smashed with heavy rakes, and then the ridges were ridged and buckled. After the ridges were turned over, the ridges were promptly suppressed with a wooden roller to prevent running squatting.
(3) The northeast spring soybean area and the Huanghe-Huaihe summer soybean area are all adopted.耙茬 is a shallow ploughing method for sowing soybeans. This method can prevent too much tillage from damaging the soil structure, resulting in soil compaction, and can reduce the cost of deep plowing machinery operations.
In the northeastern spring soybean area, shallow paddy fields are mainly used as plots of wheat. After the wheat is harvested, use a double-row disc to kill the cockroach and dip it twice on the opposite side.
In the summer and summer soybean area of ​​the Huanghe-Huai River basin, after the former winter wheat is harvested, the base fertilizer is applied first, then the disc is used to exterminate the alfalfa 2 to 3 times, and the alfalfa depth is 15 to 20 cm, and then the animal's light-duty nails are used to dig lightly. Flat sowing.
(4) The deep-loose and deep-loose soil cultivation method adopts mechanized operation. It has various methods and is flexible and flexible. It is a very promising cultivation method. More highly mechanized farms in Heilongjiang Province have been used in more than 80% of soybean growing areas. The use of deep-soil spade, till the soil without turning the soil layer, the implementation of deep loose, break the flat plowing method or cultivating plough plough the bottom layer, the formation of virtual and practical plough layer structure. The depth of ridge bottom depth is generally 15 to 20 cm. It should not be too deep. The sulcus can be deeper and deeper, usually up to 30 cm. At the same time, it is also possible to complete topdressing, weeding, earth-cultivation and other operations at the same time by means of deep looseness.
