Correct Methods and Techniques for Leaf Removal and Leaf Reduction in Vitex Bonsai
Vitex bonsai (Vitex negundo) not only has a peculiar tree shape, but its leaves are also very verdant, so its ornamental value is extremely high. However, its bizarre and strange shaping effects are often created artificially rather than being innate. That said, the branches of the environment are relatively hard, and their toughness is relatively poor.

Reasons for Yield Reduction in Continuous and Alternate Soybean Cropping and Yield-Preserving Techniques
I. Reasons for Yield Reduction in Continuous and Alternate Soybean Cropping Continuous and alternate soybean cropping causes plants to grow slowly and become short, with yellowing leaves, fewer pods, and fewer seeds, ultimately leading to a significant reduction in yield. In the short term, continuous and alternate cropping intensifies the damage from cyst nematodes, root maggots, root rot, pod borers, gray leaf spot, and malignant weeds, causes unbalanced depletion of soil nutrients, leads to deficiencies in soil nutrient elements, increases pathogenic fungi and decreases beneficial bacteria in the soil, and produces certain toxins, resulting in a severe decline in soybean yield and quality. In the long term, after long-term accumulation and reproduction, diseases, insects

Major progress made in project to control soybean yield reduction from continuous and alternating cropping
The reporter learned from relevant departments that the project "Research and Demonstration of Key Technologies for Controlling Soybean Yield Reduction under Continuous and Alternating Cropping," tendered by the Municipal Science and Technology Bureau, has achieved major progress after two years of scientific research. The project was carried out in Yilan and Bayan counties, the two counties with the largest soybean area in Harbin. Through key technology research, soybean varieties resistant to continuous and alternating cropping were selected, including Kenfeng 16, Heinong 48, Kangxian 4, and Hefeng 47. A formula fertilization technique was proposed with 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium, and
