What are the control methods for deformed mushrooms?
Deformed mushrooms mainly occur when ventilation is poor and the carbon dioxide content in the mushroom house exceeds 0.3%. Mushrooms that emerge too deep, growing out of cracks in the coarse soil, are also often deformed. For preventive measures, focus on ventilation and air exchange in the mushroom house. Ground bud mushrooms: when the compost is brought into the mushroom house with excessive moisture, when the mushroom house is ventilated too long during watering of the coarse soil, when the fine soil is covered too late, or when the temperature is relatively low, ground bud mushrooms are likely to appear. For preventive measures, master proper watering amounts and timely ventilation so that the mycelium hangs above the clay and below the fine soil.

What are the considerations when formulating feed for rabbits
Pay attention to selecting ingredients according to local conditions. The selected raw materials must not only meet the nutritional needs of domestic rabbits, but also suit local conditions, using locally available forage as much as possible. Pay attention to feed diversity. Combining a variety of feeds can play a role in nutritional complementation. Pay attention to seasonal differences. In most regions of China, green succulent feed is scarce in winter and spring, and domestic rabbits are prone to vitamin deficiency, so supplementation should be noted. Pay attention to feed palatability. Domestic rabbits like bitter lettuce, alfalfa (Medicago sativa), and soybean, and dislike forage with a musty or fishy smell. Be economical and practical.

How does the rice variety Jingxian 89 perform?
Jingxian 89 is a high-quality rice variety bred by the Foshan Agricultural Science Institute in Guangdong Province by crossing the japonica-indica hybrid progeny 677 with IR36. It took part in the Guangdong provincial regional trials in 1990-1991, with an average yield of 408.2-416.2 kg per mu, an increase of 9.07%-16.55% over the control variety Qishanzhan. In early 1992 it was approved by the Guangdong Provincial Crop Variety Approval Committee and became a variety promoted throughout the province. This variety has excellent grain quality and high protein content; according to testing by the Rice Quality Supervision and Testing Center of the Ministry of Agriculture,

Detailed Explanation of How to Make a Pig Feed Formula
1. Prepare the data: (1) The types of raw materials. (2) The nutrient content of each raw material and the content of potentially toxic and harmful substances. This is the foundation for making a pig feed formula. 2. Design the formula: Based on the known nutritional standards and the nutrient content of each raw material, reasonably determine the proportion of each raw material in the formula, so that the formula's digestible energy, crude protein, calcium, phosphorus, salt, lysine, and methionine just reach the nutritional standards without being excessive, thereby reducing costs. When designing the formula, be sure to pay attention to the scientific nature of the formula, and never add any

Feed Formulas and Scientific Preparation Methods for Lactating Sows
Lactating sows need large amounts of nutrients to support lactation. During peak lactation, the sow's milking capacity exceeds the nutrients she takes in through feed and exceeds the nutrients excreted in milk, so her body condition declines rapidly. Preparing high-quality, high-nutrient-density feed for lactating sows is the best way to resolve this contradiction. Feed Formula 1: Lactation Feed Formula 1 in Table 4-3 avoids as much as possible the use of bulky feeds such as alfalfa and rice hull bran. In the design of lactation feed formulas, unknown nutritional factors appear to be less
