Reasons for more flowers and less pods in soybean
At present, when many farmers are planting soybeans, they find that some plots of soybeans blossom more than pods, and the reasons are "five checks". First, check the soil structure, analyze whether the soil pH value exceeds the standard and continue the crop; second, check the fertilization content, analyze whether the proportion of nitrogen, phosphorus and potassium applied is reasonable; third, check the planting structure and analyze whether the planting density is reasonable; fourth, check the root of the plant; analyze whether there are diseases and insect pests in the root of the plant; fifth, check the soil moisture, analyze the size of the content, excessive drought and waterlogging will affect the pod setting rate. Only by careful inspection and detailed analysis can we draw a conclusion and deal with it properly to prevent falling flowers and pods and increase yield.

Management of soybean flower pod stage
Bean flower pod stage requires strong stems, thick green leaves, no spots. Field management is mainly to prevent premature aging, control excessive growth, protect flowers and increase pods, prevent shedding. 1. The flowering and pod setting period of soybean is the period when soybean absorbs most fertilizer. The yield of soybean can be increased by more than 15% by applying flower fertilizer skillfully. Soybean initial flowering stage generally every 667 square meters of urea 5-10 kg, poor growth should be more, strong growth luxuriant, should be less or not chase. Nitrogen fertilizer is applied in coordination with flowering stage, phosphorus, potassium fertilizer, boron, molybdenum and other trace fertilizers are sprayed on leaves. Generally spray twice, each time

Occurrence characteristics and control techniques of soybean red spider
The soybean red spider is a cinnabar spider mite, which belongs to the family Tetranychidae. Affected by high temperature and drought in 2007, soybean red spider occurred in an area of 120 million mu in Heilongjiang Province, resulting in a serious reduction in soybean production. According to the survey, in recent years, the damage of soybean red spiders has become the main position, generally reducing soybean production by 20-30% and serious plots by 70-90%. First, morphological characteristics. The adult is 0.3-0.5 mm long, reddish brown and has 4 pairs of feet. The female mite is 0.5 mm long and has eggs.
