Last Updated: 2024/11/06, The control technology of continuous cropping of soybean can slow down the effect on yield. The effect on soybean yield. Different environments have different effects on soybean yield. ① heavy cropping and light continuous cropping; heavy ② in the west and southwest and light in the north and east; heavy thin land and light fertilised land in ③; heavy slope in ④, light in low wet area; heavy dry year and young rain in ⑤; heavy no or less fertilization in ⑥, light in more fertilizer; heavy sowing in ⑦ and light in ploughing and renovation; heavy underground diseases and insect pests in ⑧, light in underground diseases and insect pests; ⑨ mature land is heavy, newly reclaimed land is light; ⑩ drought is heavy, irrigation is light.

The effect on soybean yield. Different environments have different effects on soybean yield. ① heavy cropping and light continuous cropping; heavy ② in the west and southwest and light in the north and east; heavy thin land and light fertilised land in ③; heavy slope in ④, light in low wet area; heavy dry year and young rain in ⑤; heavy no or less fertilization in ⑥, light in more fertilizer; heavy sowing in ⑦ and light in ploughing and renovation; heavy underground diseases and insect pests in ⑧, light in underground diseases and insect pests; ⑨ mature land is heavy, newly reclaimed land is light; ⑩ drought is heavy, irrigation is light. The East fourth League in Inner Mongolia Autonomous region is similar to its neighboring provinces, in which the Huleng area is similar to the northern part of Heilongjiang Province, and the serious phenomenon is also very serious. Today, I would like to talk about three issues: the first is the effect of soybean continuous cropping on soybean yield and quality; the second is the reason of soybean continuous cropping; the third is the control technology.

Effect on the quality of soybean

The 100-grain weight of continuous cropping soybean decreased, the diseased grain rate and insect feeding rate increased, and the commodity quality decreased significantly. According to the investigation in Fujin, Hulin and other places in Heilongjiang, the average 100-grain weight of pre-cropping soybeans is 18.2 grams, which is 2.7% lower than that of normal-cropping soybeans, and the average 100-grain weight of continuous cropping soybeans is 18.0 grams, 3.7% less than that of regular-cropping soybeans. The diseased grain rate and insect feeding rate of soybeans in the first cropping increased by 39.7% respectively compared with the first stubble, and the diseased grain rate and insect feeding rate of continuous cropping soybeans increased by 95.5% compared with the first stubble. The protein and fat content of soybean was significantly increased and decreased after more than three years of long-term cropping, while the protein content and fat content of soybean were significantly increased after more than three years.
