Characteristics of the Jinda 74 soybean variety
Jinda 74, a new soybean variety recently bred by Professor Li Guiquan, a soybean expert at Shanxi Agricultural University, has become one of the 3 new soybean varieties most recently approved this year by the Shanxi Provincial Crop Variety Approval Committee, thanks to its advantages of strong drought resistance, good yield performance, high resistance to mosaic virus, and great yield-increasing potential. Jinda 74 was developed by crossing and selecting Jinda 52 and Jinda 47. It is a dual-purpose variety for both spring and summer sowing, and is especially suitable for planting in land with high fertility and ample water. Experts say that under conditions combining good seed, good methods, and good land, the yield can

Soybean Disease Control Technology: How to Use Junke Duke
Junke Duke (2% Ningnanmycin aqueous solution) is a brand-new biological pesticide successfully developed by the Chengdu Institute of Biology, Chinese Academy of Sciences. It features high efficiency, a broad spectrum, environmental friendliness, and the ability to promote crop growth and improve quality and income. It has a very good control effect on soybean root rot, phytophthora blight and other diseases. I. Control of Soybean Root Rot 1. Symptoms When infected at the seedling stage, brown oval, elongated or irregular lesions form on the diseased plants and the base of the stems, slightly sunken, then developing into large patches surrounding the main stem and even damaging the lateral roots. In the later stage, the roots of diseased plants turn dark brown, the epidermis rots, and the lateral roots and fibrous roots are few or necrotic. The diseased plants are stunted and yellow, and the lower leaves drop early. Except for a few seriously damaged at the seedling stage, diseased plants generally do not die, but they bear few pods and few seeds, affecting yield.

Detailed Introduction to the Soybean Variety Kangxian 2
Kangxian 2 was developed by the Saline-Alkali Land Crop Breeding Research Institute of the Heilongjiang Academy of Agricultural Sciences in collaboration with the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences. In 1982, a sexual cross was made using Nenfeng 9 as the female parent and (Nenfeng 10 x Frenklin) F2 as the male parent. The progeny were continuously planted and identified in a soybean cyst nematode disease nursery, combined with southern multiplication and generation advancement, and selected and bred using the modified pedigree method, producing a new soybean variety with high resistance to soybean cyst nematode. Original code: Fuyu 8201-205. Characteristics: This variety has an indeterminate podding habit, a plant height of about 95 cm, and the main stem has 16 to
