Rice physiological red blight can be controlled with raw gypsum powder
Rice physiological red blight often occurs in cold-waterlogged mountain valley fields and in paddy fields where organic green manure has not fully decomposed. This disease mostly occurs at the tillering stage of rice, showing as very little tillering, leaves turning yellow-brown, and tea-brown irregular spots on the first and second leaves from the base; some mistake it for leaf blast. When the rice hills are pulled up, the root system is yellow-brown, and in severe cases black; the seedlings do not grow, commonly called "fa qiu". There are three main causes of physiological red blight: first, toxic substances such as hydrogen sulfide produced during the decomposition of green manure; second, some cold-waterlogged

What are the control methods for early heading in rice?
This year, the Yangtze River and Huai River basins have experienced persistent drought with little rain, causing severe impacts on agricultural production. In July-August, rice in the rice-growing areas north of the Yangtze River and in the Huai River basin showed "early heading" to varying degrees. Field performance: 2-3 early heads per hill, differing from late-developed tillers by more than 7-10 days, clearly showing "second flush heads" or "third flush heads". To make up for the losses caused by "early heading" to field production as early as possible, the causes of early heading are analyzed below, and rescue methods are proposed. The length of the rice seedling age is closely related to the early heading phenomenon.

Detailed Explanation of the Method and Technique for Brewing Yellow Rice Wine from Potatoes
Potatoes are rich in starch and highly nutritious. Using potatoes as the raw material to brew yellow rice wine not only keeps costs low but also produces good wine quality. 100 kg of potatoes can yield about 85 kg of 50-proof yellow rice wine. Pretreatment. Wash and peel potatoes that are free of pests, disease and rotten spots, then put them in a pot and boil. After taking them out and letting them cool, pour them into a large earthenware vat or stainless steel pot and mash them into a paste with a wooden stick. Prepare the starter material. For 100 kg of potatoes, use 100 g each of Sichuan pepper and fennel, add 20 kg of water, bring to a boil over high heat in a pot, then simmer over low heat for 30-40 minutes. Take out and cool

Standardized Cultivation Techniques for Dry-Raised Sparse Planting of Rice in Ningxia
Clean the pear orchard by scraping off the rough and cracked bark on the trees to destroy the cocoons and pupae of pests such as the pear fruit borer and the pear stinging caterpillar; sweep up dead branches, fallen leaves and mummified fruit to reduce the sources of infection for diseases such as pear scab, brown spot and powdery mildew; prune out diseased and damaged leaves, branches and trunks to eliminate the overwintering larvae of the pear bark miner and the pear stem sawfly; the cleared material should be buried deep in a centralized pit or burned. Irrigation and fertilization: irrigate during the period from leaf fall to soil freezing to improve the pear trees' winter hardiness; in spring, irrigate 10 days before flowering, and according to tree age and tree vigor, apply 0.5-1 kg of urea per tree to promote flowering and leaf development. Deep digging of the tree plate
