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

Detailed Explanation of Key Technical Points for Soft-shelled Turtle-Rice Ecological Rotation
In recent years, China's soft-shelled turtle farming industry has developed rapidly. Adopting the soft-shelled turtle-rice rotation model can achieve rice cultivation without fertilization, while planting rice can also improve the bottom substrate of turtle ponds and reduce the occurrence of turtle diseases. Zhejiang Qingxi Soft-shelled Turtle Industry Co., Ltd. began conducting soft-shelled turtle-rice rotation experiments in 1999, and in practice summarized the ecological rotation model of "raising soft-shelled turtles for 2-3 years, planting one season of rice," which has been promoted and applied in production. 1. Construction of Rice-Planting Turtle Ponds. Each pond has an area of more than 3 mu, with the largest reaching

Wuchang rice drinks fruit juice and takes calcium tablets to grow into ecological rice
Have you ever heard of a rice nutrient solution that people can drink? The fruit enzyme made by Liang Yingfen of Wuchang City, Heilongjiang Province, is drinkable by people. She used her homemade nutrient solution to replace rice foliar fertilizer, and the organic rice she produced was praised by experts for its high nutritional value. Liang Yingfen is a Korean ethnic farmer from Minle Township, Wuchang City. A rice blast disease in 2004 nearly wiped out all 6 mu of rice in her family. After many years of working with rice, Liang Yingfen realized that continuing to use chemical fertilizers and pesticides was very dangerous. The soil was getting poorer the more it was farmed, crop diseases and pests were increasing, and especially the residues of chemical

Detailed introduction to the new late japonica rice variety Xiushui 217
Xiushui 217 was approved in March 2003 at the 27th variety approval meeting of the Provincial Crop Variety Approval Committee. In the 2000 provincial regional trial, this variety had an average yield of 428.63 kg per mu, 0.14% less than the control Xiushui 63 (not significant); in the 2001 provincial regional trial, the average yield was 509.54 kg per mu, 11.30% more than the control Xiushui 63 (reaching an extremely significant level); the two-year average yield was 5.28% higher than the control Xiushui 63. The two-year average whole growth period was 136.4 days, 2.8 days longer than the control Xiushui 63. 2

What issues should be paid attention to in the management of single-season rice and other field crops
In the past week, the weather has continued to be hot with strong sunlight, field evaporation has been very high, and some rainfed fields have already experienced water shortage and drought. In the management of single-season rice and other field crops, attention should be paid to the following issues: 1. Spraying for disease and pest control should be done in the morning and evening, and sufficient water should be used. At present, it is the suitable period for controlling the fourth (2) generation leaf roller and rice planthopper of single-season rice. When selecting appropriate pesticides for control, the spraying time should preferably be before 8 a.m. or after 5 p.m., avoiding the high-temperature and strong-sunlight period as much as possible, and sufficient water should be used

Detailed Explanation of Key Techniques for High-Yield and High-Quality Cultivation of Black Rice
Black rice is an ancient and precious rice variety in China. It is rich in nutrients and has the functions of nourishing yin and replenishing blood, darkening hair and preventing aging. It has always been eaten as a tonic, and among the people it has the fine names of blood-nourishing glutinous rice, bone-setting glutinous rice, medicinal rice, longevity rice and monthly rice (eaten by women during confinement). Black rice is mainly distributed in Yunnan, Guizhou, Guangdong, Guangxi, Hunan and Shaanxi provinces. In the long course of cultivation, many precious farmer varieties have been formed, such as Yunnan Jinggu purple rice, Guizhou Huishui black rice, Guangxi Donglan ink rice and Hunan southwestern Hunan black glutinous rice. However, these varieties generally have tall plants, loose plant type, drooping leaves,

Neolitsea sericea is a native tree species of Shanghai
Neolitsea sericea (Bl.) Koidz. LAURACEAE Current status: rare species. Distributed only in a relatively narrow area along the eastern coast of China. According to literature records, it is also distributed in Chongming Sheyu, Shanghai. Due to excessive felling for firewood, few adult trees remain, and most of them have grown from sprouts. Morphological characteristics: Evergreen tree, up to 12 m tall; branchlets greenish, smooth, current-year branches often covered with brown-yellow silky hairs. Leaves alternate, leathery, oblong or ovate-oblong,

What pesticide gives the best control effect against older larvae of the rice leaf roller?
Chlorpyrifos and abamectin-monosultap are effective agents for controlling the rice leaf roller, but they must be applied during the 1st-2nd instar young larval stage (at this stage the rice leaf roller has not yet rolled leaves and caused damage, or has just begun rolling the leaf tips and causing damage), when the rice in the field has just begun to roll leaves. For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

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.
