10 Key Measures to Increase Soybean Yield
1. Thinning: On the basis of full stands of soybeans, thin the seedlings when the two opposite simple leaves unfold, generally increasing yield by 10-20%. 2. Pressing seedlings: When the first compound leaf of some soybean seedlings unfolds, choose a sunny midday and use animal power or a machine-drawn wooden roller to press along the ridges, which can increase yield by 8.5-10%. 3. Pinching: At the early flowering or full flowering stage of soybeans, remove about 2 cm from the top of the main stem by hand, which can increase yield by 7.2%-10.8%. 4. Applying rare earth: Mix 2 kg of rare earth per 1 kg of soybean seed for seed dressing, or spray once each with rare earth solutions at concentrations of 0.03-0.04% and 0.08 during the soybean seedling stage and early flowering stage, which can increase yield by 15-20%.

Eight key technical measures for increasing soybean yield
First, applying flower-and-pod fertilizer. The flowering and pod-setting stage is when soybean grows and develops most vigorously, and it is the period of greatest fertilizer demand in the soybean's entire life. Applying flower-and-pod fertilizer can reduce flower and pod drop, promote full grains, and improve quality. Flower-and-pod fertilizer should be applied at the early flowering stage, preferably as a combined application of nitrogen and phosphorus fertilizer, with 3-5 kg of urea and 7.5-10 kg of phosphate fertilizer per mu, applied in holes opened 5 cm to the side of the soybean roots, and after application, soil should be hilled up to cover the fertilizer. Second, spraying foliar fertilizer. In addition to the three major elements nitrogen, phosphorus and potassium, boron, zinc and molybdenum are indispensable trace elements for soybean. Therefore, from the flowering to the seed-filling stage of soybean

Nano magnetic energy liquid can be used to increase soybean yield and promote early maturity
This spring, due to large temperature fluctuations, the effect of pre-emergence closed weeding in soybeans was poor, fields were overgrown with weeds and seedlings were small, the area affected by herbicide damage was large, soybean growth was hindered, root development was poor, stunted seedlings in the field were severe, and the growth process was delayed by an average of 7-10 days. 1. Main manifestations 1. New leaves grow slowly, the lower leaves turn yellow and withered, the root system shows rusty roots and reddening, and at this stage root rot also occurred over a large area; 2. Field plots with normal growth accounted for only about 20% of the total area; 3. Individual plants had fewer branches, reduced by more than 20-30%.

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
