Detailed Explanation of Key Points for Cultivating Colored Rice
Nutritional and health rice, namely red rice, black rice, and fragrant rice, are traditional premium and precious rice varieties in China. I. Fragrant indica rice. It ranks first among the four premium rice varieties first recommended by the Rice and Rice Products Quality Supervision and Testing Center of the Ministry of Agriculture. After testing and evaluation of 12 indicators, all exceed the first-grade rice standards. Its grains are jade-like in color, and the content of trace elements, especially selenium, is very high, making it the best variety for developing pollution-free green food. The fragrant indica rice plant height is 100 cm, about 150 grains per panicle, 1000-grain weight 28 g, usual yield 500-550 kg per mu, and the whole growth period is 136

What are the reasons rice seedlings are slow to tiller
1. Rice bakanae disease: Patterns of occurrence and routes of transmission: The pathogen of rice bakanae disease overwinters on grains and rice straw. The following year, if infected seeds or rice straw are used, the pathogen multiplies as the seeds germinate, invading through the coleoptile or wounds of the seedlings, causing the seedlings to develop the disease and grow excessively tall. Affected seedlings often wither and die. Infected seedlings that do not die are pale yellow-green, grow thin and elongated, generally about one-third taller than healthy seedlings; root development is poor, with few tillers or even no tillering. After infected seedlings are transplanted, they carry the pathogen into the field, causing rice plants to develop the disease. When rice heads and flowers,

Detailed Explanation of Rice-Fish-Loach Ecological Agriculture Engineering Technology
1. Environmental conditions of the production area: a good ecological environment, far from pollution sources, good air; high, thick and compact paddy field ridges, relatively clayey soil, relatively high soil fertility, and paddy fields with sustainable development capacity; good irrigation and drainage conditions, relatively sufficient water sources, and fresh water quality. 2. Paddy field engineering facilities: dig a ring-shaped ditch around the paddy field, with a ditch width of 1 m and a depth of 0.5 m; surround the field ridges with anti-escape plastic sheeting (40-50 cm above ground, buried 20-30 cm underground); install double-layer anti-escape blocking nets at the water inlet and outlet. 3. Rice, river crab,

How is the Fu'er Daohebao rice product?
Fu'er Daohebao brand rice seedling-strengthening nutrient agent is a "four-in-one" ultra-efficient seedbed nutrient substrate jointly developed by the Fu'er Group and the Chinese Academy of Agricultural Sciences, including a fertilizer enhancer, an acid regulator, a soil conditioner, and a mother agent. This product is suitable for rice seedling-raising areas in the cold regions of the north (except for saline-alkali land seedling-raising areas). A single application can provide the required nutrients, and it has effects such as seedbed soil disinfection, acid regulation, biochemical control, and root promotion. It can achieve the "one controls three" effect of enhancing stress resistance (disease resistance, cold resistance, low-temperature resistance), cultivating strong seedlings, and improving yield and quality. 1. Rake

A Brief Introduction to the Characteristics and Traits of the A Dao No. 7 Rice Variety
The new late-maturing, high-yield rice variety A Dao No. 7 was introduced by the Fine Seed Multiplication Farm of the First Agricultural Division in 1992 from the Liaoning Provincial Institute of Saline-Alkali Land Improvement and Utilization, and was systematically selected and bred over 5 consecutive years. Characteristics and traits: This variety belongs to the late-maturing, japonica rice type. When sown around the end of April in the Tarim River and Shajingzi reclamation areas, it can fully mature by the end of September, with a whole growth period of 150-155 days. The mature plant height is about 90 cm, the plant type is relatively compact, and it has strong tillering ability. Emergence, heading, and maturity are neat and uniform. The plants are clean and robust, maturing while still green without premature senescence; the panicle position is relatively low, with the flowers hidden among the leaves. The grain

How do you rescue rice seedlings poisoned by trichloroacetaldehyde?
Phosphate fertilizer contains trichloroacetaldehyde and trichloroacetic acid. If phosphate fertilizer is applied excessively during rice seedling raising, or if inferior phosphate fertilizer with a high content of trichloroacetaldehyde (acid) is applied, the rice seedlings may suffer trichloroacetaldehyde (acid) poisoning. In mild cases, the seedling leaves curl and shrink, tillers grow in clusters, and brown necrotic streak spots appear at the leaf tips; in severe cases, the streak spots spread from the leaf tips toward the middle and base of the leaves, tillering decreases or stops, the root system becomes abnormally short and thick, and may even rot and turn black, ultimately killing the entire plant. For fields where the seedlings are only mildly affected, immediately adopt the method of irrigating by day and draining by night, repeatedly flushing with water

Disease- and pest-resistant japonica rice successfully bred in Jiangsu
A breakthrough has been achieved in the "Breeding of New Multi-Resistant, High-Yield and High-Quality Japonica Rice Varieties" carried out through cooperation between the Bokun Agricultural Research Institute of Yixing City, Jiangsu Province, and the China National Rice Research Institute and other institutions. New high-yield, high-quality japonica rice lines such as 4701 and 4714 have been successfully bred with resistance to brown planthopper, rice blast and other pests and diseases. It is reported that the bred high-yield, high-quality japonica rice lines combine genes for resistance to brown planthopper, white-backed planthopper, rice blast and stripe leaf blight, as well as specific genes for high yield and high quality. Testing has shown that these high-quality japonica rice lines are resistant to brown planthopper,
