What are the key cultivation techniques for rice-following beans?
Rice-following bean cultivation is a method in which, after the autumn rice harvest, the field is not ploughed or harrowed; instead, trenches are made, the field is divided into beds, and drainage is carried out, then soybeans are broadcast or dibbled on the bed surface and covered with rice straw. It has the advantages of simple planting, saving labour and time, low input, and good results, and is a short, flat, and fast project for raising multiple cropping and increasing grain, feed, and income. 1. Select improved varieties. There are many local soybean varieties; after mass purification and rejuvenation, those with good ecological adaptability, high yield, and disease resistance and with a moderate growth period can all be selected; for

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

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
