How to Achieve Early Maturity and High Yield in Soybeans
1. Choose suitable varieties. When selecting seeds, choose varieties with shorter plant height that can be planted at wider spacing; these varieties have relatively lower water requirements and suffer less yield loss in dry years. 2. Strengthen field management and weed promptly. Weeds compete with soybeans for fertilizer and water, affect photosynthesis and hinder ventilation, so weeds must be removed promptly. Cultivate and hill up at the right time. When cultivating and hilling, cultivate deeply and hill up plenty of soil to enhance soil permeability and its capacity to retain water and fertilizer. 3. Apply sufficient base fertilizer. On the basis of applying farmyard manure, the amount of chemical fertilizer applied must not be

How good is the soybean variety Shandou 125?
The high-quality soybean Shandou 125 is a new soybean variety developed by the College of Agronomy, Northwest A&F University in 1988 through sexual hybridization and pedigree selection. Its original line code was 88125-3-7-4. In 1988, So-3-4 was used as the female parent and the Japanese variety Ri 9-11 as the male parent for hybridization, and 21 F1 seeds were harvested that year. In 1989, the F1 generation was planted, showing mid-early maturity and good disease resistance. After eliminating false hybrids, 16 uniform single plants were harvested. In 1990, the F2 generation was planted, with wide segregation and many types.

Introduction to the Shennong 6 soybean variety and its cultivation key points
[Basic Information] Shennong 6 (original line number Shennong 91-44) was bred by the Department of Agronomy of Shenyang Agricultural University in 1986 through sexual hybridization, using Fengjiao 66-12 as the female parent and Kaiyu 8 as the male parent, selected according to breeding objectives. Since Shennong 6 was introduced to Pulandian City in 1996, it has withstood the test of different years and different climatic conditions (low temperature and scant sunlight, high temperature and drought), consistently showing high and stable yield, disease resistance, and lodging resistance, with an average yield increase of 18.7%-24.7% over the control. In order to fully bring out the excellent varietal characteristics of Shennong 6,

Detailed Explanation of Main Soybean Disease Control Measures
Soybean mosaic virus disease The pathogen of soybean mosaic virus disease is a virus, and there is currently no specific chemical agent. The key to controlling this disease is to control the occurrence, spread and damage of aphids, so as to "cut off the source of the virus and control the disease by controlling the insect." Apply pesticides in a timely manner in the early stage of aphid occurrence and keep them under control at the beginning of the peak period. 1. Agricultural control: ① Promote disease-resistant (tolerant) varieties; ② Strictly select seeds before sowing and remove brown spot seeds; ③ Establish a virus-free (low-virus) seed propagation system and healthy seed fields. Healthy seeds should be selected for seed fields, and diseased seedlings should be removed in combination with hoeing before aphids occur. Seed fields should be isolated from virus sources by more than 100 m to prevent the spread of the pathogen; ④ Avoid late sowing so that the susceptible period avoids the aphid peak; ⑤ When aphids appear in soybean fields, control them in a timely manner. 50% pirimicarb wettable powder and 5% fenvalerate emulsifiable concentrate may be used; ⑥ Clear weeds around the farmland. 2. Physical or biological control: Silver-gray plastic film may be placed in the field to repel aphids. The amount and frequency of chemical pesticide application should be minimized in the field to protect natural enemies of aphids such as green lacewings, ladybugs and hoverflies. 3. Chemical control: Start spraying for control before the onset of viral disease or in the early stage of the disease. In July to August, agents for controlling viral diseases may also be sprayed in combination with aphid control. 4. Commonly used agents: 2% Jun Ke Du Ke aqueous solution, 20% Virus A wettable powder, etc. 5. Scope of application: All soybean production areas. 6. Precautions: Spraying should be uniform with no missed areas, and application should be continuous 2 times with an interval of 7 days to 10 days each time; actions should be unified and control should be concentrated and contiguous. Agents should be used alternately to prevent the development of aphid resistance.

Interplanting autumn soybeans in rice paddies yields good increases in both output and income
According to trials: after the mid-season rice harvest, by using the temperature and light conditions in the field, planting an additional season of autumn soybeans can increase soybean yield by 60-120 kg/mu, with economic income of 150-420 yuan/mu, giving a relatively good effect of increasing both output and income, and it is suitable for extension in ratoon rice areas below 400 m in altitude. The key technical points are as follows: 1. Suitable site and good varieties: fields below 400 m in altitude with no water for retaining ratoon rice, as well as all rice seed production fields, can be planted. After the rice grains have set, open ditches to drain water; after the rice harvest, promptly clear weeds and rice stubble, without plowing, and according to

How to grow spring-planted soybeans in Northeast China? A detailed explanation of the technical guidance
In the autumn and winter of last year, precipitation in Northeast China was lower than normal, soil moisture was insufficient, and drought was relatively severe. This spring there has been more rain and snow, temperatures began to rise rapidly in early April, and temperature and precipitation are close to normal. The Soybean Expert Steering Group of the Ministry of Agriculture, together with the National Agricultural Technology Extension Service Center, based on full investigation, proposed the following technical guidance for spring soybean planting: 1. Strictly select excellent varieties. Because of the dry climate last autumn, soybeans may not have matured normally physiologically at harvest, and mechanical threshing increased the possibility of damage to the seed embryo

Detailed Explanation of Mid-to-Late Stage Management Techniques for Soybeans in Northeast China
The main soybean-producing areas in Northeast China and Inner Mongolia have generally suffered from a disaster pattern of spring drought followed by spring waterlogging. Drought, low temperatures and insufficient sunlight have caused slow plant growth, and have also increased the occurrence of herbicide injury, weed infestation and diseases. At present, plants generally have 2-3 fewer compound leaves than in the same period of a normal year, and growth is uneven. Therefore, cultivating strong seedlings, building a reasonable population structure, promoting early maturity and preventing lodging are the key tasks in mid-to-late stage field management of soybeans, and at present special attention must be paid to draining waterlogged soybean fields and preventing waterlogging damage. Recently, the soybean expert guidance group of the Ministry of Agriculture and the National Agricultural Technology
