What is the difference between the two rice diseases? Explained clearly in one article
In recent years, bacterial brown spot of rice has shown a trend of relatively severe occurrence in some rice areas of our province. Most farmers mistakenly treat this disease as rice blast, which both increases costs and fails to achieve good results. For this reason, the two diseases are specifically distinguished below. 1. Symptoms. The symptoms of bacterial brown spot of rice are that reddish-brown small spots first appear on the upper leaves of the rice starting from the leaf tip and leaf edge, then expand into spindle-shaped, long oval, or irregular strip-like streaks, gradually spreading to the entire leaf, causing local necrosis of the leaf, with no bacterial ooze visible

Detailed Explanation of Key Cultivation Techniques for Liangyou Peijiu Rice
Liangyou Peijiu is a two-line high-yield hybrid mid-season rice variety bred by the Jiangsu Academy of Agricultural Sciences, and was approved by the Hubei Provincial Crop Variety Approval Committee in 2001. This variety has a compact plant type, hard stems, dark green leaves, and erect flag leaves. The panicle is spindle-shaped, with large panicles and many grains, and grains are densely set. The grains are medium-long, with a high seed-setting rate and a relatively low 1000-grain weight. Grain quality is relatively good. It shows an obvious two-stage grain-filling phenomenon, and color conversion at the late stage is average. The whole growth period is about 139 days, 3-4 days longer than Shanyou 63. It is moderately susceptible to bacterial leaf blight and highly susceptible to panicle neck blast. It is moderately affected by sheath blight.

What are the remedial measures after rice suffers from flooding?
Rice has strong waterlogging tolerance. After being submerged for about 3 days, about 80% of the rice seedlings can still survive, and it is enough to strengthen management. After being submerged for 4-7 days, 50%-80% of the rice seedlings survive, so it is necessary to promptly thin and replant seedlings to ensure a sufficient population. After being submerged for more than 7 days, only about 30% of the rice seedlings survive, so replanting or switching to other crops should be considered. It is necessary to adapt to local conditions, provide guidance by category, and carefully carry out post-disaster management of rice. As long as rice seedlings still have green leaves, the inside of the leaf sheath is still green and has a certain hardness, and the white roots or root system are light yellow, and 2-

Four key passes must be secured in controlling rice sheath blight
In recent years, sheath blight has risen to become the most important disease of rice, and it has four major characteristics: First, it occurs over a wide area. Second, there are very few varieties resistant to sheath blight. Third, the degree of damage is increasingly serious, even causing the plants to break through the top and lodge. Fourth, it first develops on the lower part of the rice plants, making it easy to overlook and miss the favorable timing for control. In control strategy, strictly securing the four passes is the key. 1. The pass of salvaging sclerotia - sheath blight mainly overwinters in rice fields in the form of sclerotia, and overwintering sclerotia generally have 60%-70% able to germinate from winter and spring through to early rice transplanting. The vast majority of sclerotia are lighter than water and can float with the water for a long time. After the rice field is irrigated,

What are the methods for treating licorice seeds?
1. Sulfuric acid treatment method. For every 1 kg of clean seeds, use 20-30 ml of 80% sulfuric acid and stir evenly. Once uniform sulfuric acid etching marks are visible on the seed coat, rinse with clean water and dry in the sun for later use. The treatment time depends on temperature and the amount of acid added. With the same amount of acid, the treatment time is shorter when the temperature is high and longer when the temperature is low. With more acid added, the treatment time is shorter; conversely, the treatment time is longer. 2. Seed coat crushing method. Place the seeds on a grinding pan at a thickness of 3 cm, turning them as you grind. When the seed coat is ground to a yellowish-white color

Intercropping Cultivation Techniques for Licorice in Land Returned from Farmland to Forest
Intercropping licorice in land returned from farmland to forest can both conserve soil and water and increase economic returns, achieving the goal of using the land to support the forest and the forest to support the land, and realizing a "win-win" for both the economy and ecology. Since 2002, Regiment 137 has conducted cultivation trials of intercropping licorice in land returned from farmland. After several years of experimentation and exploration, breakthrough progress has been made. 1. Land selection: Select sandy loam plots of land returned from farmland to forest with relatively low salinity and alkalinity, relatively few field weeds, and good drainage for intercropping licorice. The main tree species planted in the sowing area is wolfberry seedlings; the planting pattern is furrow planting

What to do about pigeon dysentery? It can be treated with the Chinese herb licorice
When a pigeon suffers from dysentery, its droppings are as thin as water, green with a yellow tinge. The sick pigeon huddles in the coop, drinking large amounts of water but not eating, and its condition worsens by the day. Buy licorice, mash it up and administer it to the sick pigeon by mouth, and also soak licorice in water for the sick pigeon to drink. The next day the droppings had already changed from thin to dry. Continue treating with licorice, and in less than a week the sick pigeon can recover. According to "Compendium of Materia Medica" by Li Shizhen, "Licorice, sweet and neutral in nature and flavor, mainly treats cold and heat pathogenic qi of the five zang and six fu organs, and resolves a hundred toxins," and "treats red and white dysentery, and taken it works immediately."
