Three ways to increase soybean production
Intermediate seedling
After soybean emergence, early seedling on the basis of the whole seedling is an effective measure to increase production. The effect of increasing yield mainly depends on the time of interseedling, which should be carried out urgently when two opposite single leaves are unfolded.
Press seedling
When the first compound leaf of soybean seedlings unfolds, choose a sunny day at noon, use animal power or machine to induce wood along the ridge to suppress. When pressing seedlings, we should pay attention to avoid cloudy or sunny mornings, so as not to break the seedlings.
Pick the heart
In the first flowering or full flowering stage of soybean, remove the top of the main stem about 2 cm by hand.

Ten ways to increase soybean production
First, when the soil moisture is sufficient for seedling replanting and the time can catch up, soak the seeds with the original varieties for 2-3 hours and then replant; although the soil moisture is sufficient, the farming time is already late, you can speed up budding and replanting or replanting with precocious varieties; if the replanting time cannot catch up, seedlings with not less than one compound leaf can be taken and transplanted with soil as early as possible in cloudy or sunny afternoons, and watered immediately after planting to facilitate survival. Second, if the soybean has the trend of overgrowth or greedy green late maturity, the top of the main stem can be removed about 2 cm at the early or full flowering stage of the soybean. Or use sharp iron about 33 centimeters long

Secret recipe for increasing soybean production
In order to increase the yield of soybean, in addition to selecting excellent varieties, improving the nitrogen-fixing ability of nitrogen-fixing bacteria and controlling diseases and insect pests, the following four measures can be taken: 1. The specific method is: after the formation of two cotyledons of soybean, all the undeveloped leaves in the upper part are removed. In this way, the double main branch of & ldquo; & rdquo; can be produced. After the formation of the two true leaves, all the upper undeveloped compound leaves are removed to concentrate nutrients on the new main branches, accelerate the individual cell division of the plant, and promote the sturdy stems, luxuriant branches and leaves and pods of soybean.
