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.

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.
