Control Methods for Soybean Bacterial Blight
Symptoms: It damages seedlings, leaves, petioles, stems and pods. When seedlings are infected, the cotyledons develop semicircular or nearly circular brown spots. When leaves are infected, irregular chlorotic small spots initially appear, water-soaked, and after expanding they become polygonal or irregular in shape, about 3-4mm in size, with the center of the lesion dark brown to blackish brown, surrounded by a narrow chlorotic halo ring, and after the lesions merge they form dead necrotic patches. When the stem is infected, it initially presents as dark brown water-soaked elongated strips, which after expanding become irregular and slightly sunken. When pods and seeds are infected, dark brown streaks

Detailed Explanation of Key Points for Soybean Narrow-Row Dense Planting Cultivation Techniques on Small Ridges
Key points for soybean narrow-row dense planting cultivation techniques on small ridges: 1. Crop rotation: rotate in a three-zone rotation with crops such as wheat and corn, or rotate every other year with crops such as wheat and corn, to avoid continuous cropping. 2. Soil tillage: first, flat plowing and ridging. Second, rotary tillage and ridging. Third, ridging while sowing. 3. Variety selection: choose semi-dwarf, semi-determinate type varieties with strong stems that do not lodge, are disease-resistant, high-yielding, and suitable for dense planting; the maturity period should be suitable or slightly earlier than local varieties. 4. Seed preparation: first, seed selection. Second, seed treatment. 5. Fertilization: first, increase application of

How can the new functional components of soybeans be developed and utilized?
China is the homeland of soybeans, and over the long course of history, "soybeans have nurtured the Chinese nation." Modern science has discovered that the functional components of soybeans that nurtured the Chinese nation are mainly found in soybean meal. High-temperature soybean meal is the highest-yield product of the soybean oil processing industry. Whether the effective components in high-temperature soybean meal can be extracted is key to revitalizing China's soybean oil processing industry. The National Soybean Deep Processing Technology Research and Promotion Center invented a process using high-temperature soybean meal as raw material to continuously extract high-purity soybean oligopeptides, soybean isoflavones,

Introduction to New Soybean Line 90-77-2
New soybean line 90-77-2 was developed by the Dryland Crops Research Institute of the Jiangxi Academy of Agricultural Sciences in 1987 through artificial hybridization and selection using the high-yielding variety Aijiaoqing and Gandou No. 1. It is a summer-autumn dual-purpose soybean with advantages such as a moderate maturity period, high yield and good quality, thick stems, tolerance to heavy fertilization and resistance to lodging, wide adaptability, and temperature tolerance. Grown as a summer soybean, 90-77-2 has a whole growth period of about 140 days, a sub-determinate podding habit, purple flowers, brown pubescence, and medium-sized leaves that are dark and thick. The plant is tall (90

How to prevent and control soybean phytophthora root rot? Detailed explanation of occurrence patterns and control methods
After soybean phytophthora root rot was introduced into our prefecture with the transfer of soybean seeds in July 2005, our station immediately established a soybean phytophthora root rot monitoring leading group and dispatched professional and technical personnel to carry out field monitoring work in Gongliu County. 1. Disease investigation In 2005, the affected area was 2239 hectares, and in 2006 the affected area was 2858 hectares. 1. Disease situation in Xinyuan County The soybean planting area was 0.67 million hectares, the investigated area was 0.3 million hectares, and the affected area was 0.23 million hectares, of which the sporadic occurrence area was 0.2

Key Technical Points for Scientific Management of Soybeans Adapted to Seedling Conditions
Liang Huizhen, associate researcher at the Cash Crop Research Institute of the Provincial Academy of Agricultural Sciences, said that at present most areas of our province's soybeans are at the flowering and podding stage, which is the period of greatest nutrient and water uptake and also the peak period of root nodule nitrogen fixation. The main goal at this stage is to promote more flowering and more pod setting, prevent premature senescence, control excessive vegetative growth, increase flowers and preserve pods, reduce shedding, and lay the foundation for a high yield. Due to the tight time schedule at sowing, summer soybeans often receive no or little basal fertilizer, and by the time the soybeans set pods, nutrient deficiency occurs, so flower and pod fertilizer should be applied promptly. At

Detailed Explanation of Key Points for High-Quality and High-Yield Soybean Cultivation Techniques
I. Selection of Improved Varieties The selection of superior varieties is the core to achieving high quality and high yield. With Qindou No. 8 as the main cultivar, demonstrate and promote Zhonghuang 13, Jindou 23, and Yubian 30. II. Reasonable Crop Rotation and Formula Fertilization Soybean is most averse to continuous cropping and back-to-back cropping. For fields with severe disease incidence, switch to other crops, actively promote a reasonable crop rotation system, and reduce the number of years of continuous cropping and back-to-back cropping. According to last year's soil testing survey, the N:P:K ratio in soybean planting fields in our town was 12:1:5, while the N:P:K required by soybean is 14:3

Detailed Explanation of New Techniques for High-Quality, High-Yield Soybean Cultivation
Soybean is one of the crops with a relatively short growth period. Unfavorable conditions such as drought, waterlogging, lodging, and excessive vegetative growth during the growth period can all cause significant reductions in soybean yield. To develop soybean production, it is essential to take the promotion of new high-yield, high-quality, disease-resistant varieties as the foundation, and to center on assembling advanced scientific new technologies, following the path of increasing per-unit yield and benefits. In recent years, various regions have carried out a series of innovative studies on how to increase per-unit yield and benefits, achieving good results. The relevant high-quality and high-efficiency cultivation technical measures are now compiled and excerpted here and recommended to the broad community of farmers. 1

Detailed Explanation of Key Techniques for Uniform Planting and High-Yield Cultivation of Soybeans
1. Determine planting density, row spacing and plant spacing according to varietal plant-type traits, branching and other characteristics. (1) Short-stalked, early-maturing, main-stem-type varieties resistant to lodging and branching: row spacing 30-40 cm, plant spacing 8-10 cm, retained seedling density 18,000-25,000 plants. 2. Determine planting density according to soil fertility level and management level at the plant spacing. After determining the planting row spacing according to the variety, density adjustment should also be made according to soil fertility conditions and water-fertilizer management level. 3. Sufficient soil moisture and early sowing. Early sowing can significantly increase yield and increase fat content
