Detailed Explanation of Key Soybean Cultivation Techniques for Increasing Yield
1. The ecotype of soybean varieties should be appropriately selected according to the natural conditions of the local soybean production area. Soybean podding habit can be divided into 3 types: indeterminate, determinate and semi-determinate. Lao Zhao is located in Zhumadian, which belongs to the Yangtze River Basin spring and summer soybean zone, with a summer crop of 120—150 days. In this region, varieties with determinate podding habit should mainly be selected for planting, though indeterminate podding varieties may also have been chosen, which would lead to the above phenomenon. Therefore, attention should be paid to variety selection, especially in areas with relatively high soil fertility and abundant rainfall.

Soybean yield-boosting secrets: master these methods for higher yields
To increase soybean yields, besides choosing excellent varieties, improving the nitrogen-fixing capacity of nitrogen-fixing bacteria, and controlling pests and diseases well, the following four measures can also be taken: 1. Pinching the seedlings. The specific method is: after the two cotyledons of the soybean have formed, remove all the unexpanded true leaves at the top. In this way, "double main branches" can emerge. After the two true leaves have formed, remove all the unexpanded compound leaves at the top, so that nutrients are concentrated on the new main branches, accelerating the individual cell division of the plant, promoting thick and strong soybean stems, luxuriant branches and leaves, and pods

Three methods to increase soybean yield, simple and practical
Thinning: After soybean seedlings emerge, thinning early on the basis of a full stand is a proven yield-increasing measure. Its effect depends mainly on how early thinning is done; generally it should be carried out promptly when the two opposite unifoliate leaves have unfolded. Seedling pressing: When the first compound leaf of the soybean seedling has unfolded, choose a sunny noon and press the seedlings along the rows with a wooden roller drawn by animal power or machinery. When pressing, be careful to avoid cloudy days or sunny mornings, so as not to break the seedlings. Pinching: At the early flowering or full flowering stage of soybean, remove about 2 cm from the top of the main stem by hand.

Ten Ways to Increase Soybean Yield, Teaching You to Easily Boost Production
1. Checking seedlings and reseeding When soil moisture is sufficient and time still allows, soak seeds of the original variety for 2-3 hours before reseeding; if soil moisture is sufficient but the farming season is already late, you can germinate seeds before reseeding or use early-maturing varieties for reseeding; if the reseeding time cannot be met, you can as early as possible on a cloudy day or a sunny afternoon take seedlings with no less than one compound leaf and transplant them with soil, watering immediately after planting to help them survive. 2. Pinching the growing tip and removing leaves For soybeans showing a tendency toward excessive vegetative growth or late maturation with prolonged greening, you can pinch off about 2 cm from the top of the main stem at the early flowering stage or full flowering stage. Or use a sharp iron strip about 33 cm long

New soybean topping technique for higher yields: operate this way to get a bigger harvest
Soybean terminal buds have strong growth vigor and consume a lot of nutrients. Removing the terminal buds of soybean transfers nutrients to the pods, which helps increase yield. This is especially true for soybean with higher soil fertility and vigorous growth; timely removal of the terminal buds makes the yield-increasing effect even more pronounced. The method for removing soybean terminal buds is: at the early flowering stage, the peak of soybean growth, pinch off the 2-3 cm tender tip at the top of the main stem, so that apical growth is inhibited and nutrients are concentrated for reproductive growth, promoting more flowering and more pod setting, and helping to make the plants shorter and sturdier and enhance stress resistance. Soybean topping should follow the “three

Soybean Narrow-Row Dense Planting Cultivation Methods and Technical Key Points
Soybean narrow-row dense planting cultivation is currently an advanced cultivation technique with a relatively large application area and rapid development rate in soybean cultivation internationally. Since the early 1990s, our province, on the basis of absorbing and digesting foreign techniques and in combination with the province's natural characteristics and production conditions, has explored a soybean narrow-row dense planting cultivation technique suitable for the province's production conditions. Soybean narrow-row dense planting is divided into two modes: flat-planting narrow-row dense planting and ridge-planting narrow-row dense planting. The former high-yield cultivation technique is flat sowing, flat management, a narrow-row dense planting cultivation that stays flat throughout, and the latter refers to narrow-row dense planting cultivation based on ridge planting

Detailed Explanation of Key Points for Soybean Narrow-Row Dense Planting Cultivation Technology
Soybean narrow-row dense planting cultivation is currently an advanced cultivation technology with a relatively large application area and rapid development speed in international soybean cultivation. Heilongjiang Province began this practice in the early 1990s and designated it as a key research project of the Provincial Party Committee in 1995. 1. Select suitable varieties and carry out proper seed treatment. Narrow-row dense planting must select short-stalked or semi-short-stalked varieties with lodging resistance and high yield potential. Currently, the more suitable varieties applied in production include Hefeng 25, Hefeng 35, Suinong 14, Beifeng 14, Beifeng 1

Key Technical Points for Field Management of Soybeans in the Mid-to-Late Growth Stages
I. Management During the Flowering and Podding Stage During the flowering and podding stage, the main management tasks are to strive for more flowers, early flowers, uniform flowers, increased flowers, and increased pods, and to prevent flower and pod drop. Management should be based on observing the plants, combining preservation and control; for high-yield fields, control should be the main approach, avoiding premature canopy closure and shading, so that maximum leaf area is reached at the end of flowering. Specific measures: continue hoeing weeds before canopy closure, and apply irrigation and fertilizer as appropriate based on plant condition; at the early flowering stage, fertilizer should be applied to weak plants, but not to vigorous plants to prevent excessive vegetative growth. Applying phosphate fertilizer during the flowering and podding stage has an obvious effect; during this period, soybean leaf area reaches its maximum, water consumption increases, and both transpiration intensity and water demand

The key to soybean planting is to do a good job of three early tasks.
1. Early weed control. 3-4 days after soybean sowing and before emergence, use 50% acetochlor emulsifiable concentrate at 100-150 ml/mu, mixed with 30-40 kg of water for soil sealing. If weeds are already present in the field at the time of application, add 20% paraquat at 100 ml/mu and mix it in. If soybeans have already emerged and there is no time for soil sealing, use 10% quizalofop-p-ethyl emulsifiable concentrate at 60-75 ml/mu, or 15% fluazifop-p-butyl emulsifiable concentrate at 60-75 ml/mu, or 12.5% haloxyfop emulsifiable concentrate at 60-75 ml/mu, mixed with 40

How Does Soybean Cultivation Improve the Soil? A Detailed Guide to Practical Techniques
1. Soil Conditions for High-Yielding Soybeans Soil conditions are the foundation of high soybean yields. Soil moisture status, nutrient status, and certain physical properties of the soil are important factors affecting soybean yield. Soybean seeds require more moisture to germinate than cereal crops. Soybean seedling roots are relatively tender and high in water content, so suitable soil moisture conditions are needed to promote deep elongation of the young roots. The main root of the plant can reach about 1 m, and lateral roots can extend horizontally to about 0.5 m. When soil moisture is insufficient, both vertical and horizontal root growth are affected.
