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

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,

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

The concept of specialty rice Specialty rice refers to rice with specific genetic traits and special uses, mainly distinguished from ordinary rice by the particularity of its use. Specialty rice generally includes three categories: colored rice, aromatic rice and special-purpose rice. Although its varieties account for only about 10% of rice germplasm resources, it has received widespread attention at home and abroad because of its special nutritional, health-care and processing-and-utilization characteristics.

Correct Methods and Technical Key Points for Returning Rice Straw to the Field
1. Rice straw mulching in wheat fields. After wheat sowing is completed, use 250-300 kg of rice straw per mu, cut into 10-20 cm straw segments, and spread evenly over the field so that the straw does not form piles and the soil is not left exposed. 2. Rice straw mulching in rapeseed fields. When transplanting rapeseed, plant the seedlings according to the specified spacing into holes with sufficient basal fertilizer, cover with soil, and then evenly spread rice straw over the whole field at 300 kg/mu, so that the straw does not cover the holes (seedlings) and the soil is not left exposed, while also applying integrated chemical weed control and necessary field management measures. 3. Drainage and
