Key Points of Rice Seedling Cultivation Technology: How to Grow High-Yield Seedlings
Rice is the main food crop in the lakeside lowlands of southern Shandong and southwestern Shandong, with high yield and strong marketability. However, in recent years, mixed varieties and severe diseases have affected the income of farmers in rice-growing areas. Therefore, all rice seedling cultivation techniques must be properly implemented to lay a solid foundation for a bumper rice harvest. 1. Select high-quality varieties. Although Yujing No. 6 rice has relatively poor disease resistance, it has excellent quality, strong photosynthetic efficiency and compensatory capacity, and good yield potential, so it should still be the main variety this year. Lindao 11 and Zhendao 88 can be planted in combination, and Shengdao 80 can be planted for demonstration.

Detailed Explanation of Key Points in the Quick-Freezing Processing Technology for Icefish
Quick-frozen icefish are exported to Japan, Southeast Asia, Europe and other places, and are especially popular with Japanese consumers. With the continuous increase in icefish yields from reservoirs, quick-frozen icefish has become one of China's export aquatic products with a relatively high foreign exchange earning rate. 1. Preservation and transportation of raw fish. Icefish have small bodies and thin skin, are highly prone to spoilage, and have a strong seasonal production period. To ensure the quality of the icefish, ice can be brought aboard the boat during fishing so that preservation can be carried out immediately. The specific method is to first sort and classify the caught icefish on the boat,

Processing Technology for High Viscoelastic Surimi Products (Part One)
When processing and making various surimi foods, the choice of fish species and the freshness of the fish are very important; they affect the elasticity of the product, so in surimi raw materials, there is a certain limit to the amount of soybean and wheat protein powder mixed in; too much will weaken the elasticity of the product. In order to solve the elasticity problem of aquatic surimi products, a new method is adopted in which fish protein alone or mixed with plant protein is made into protein fibers, and then mixed with surimi to produce surimi foods with excellent viscoelasticity, which can enhance the elasticity of Grade C low-quality surimi to above Special Grade A. The production method takes the original

Key Points of Compost Fermentation Technology in the Cultivation of Agaricus bisporus (Button Mushroom)
Compost fermentation is divided into the one-phase fermentation method and the two-phase fermentation method. (1) One-phase fermentation method: 1 day before building the heap, cut the rice (wheat) straw into sections and drench it thoroughly with clean water so that it fully absorbs water, then leave it piled for 1 day. 7-10 days before building the heap, wet the dry manure with clean water or urine water, then build it into a heap for fermentation. When building the heap, arrange 1 layer of manure and 1 layer of straw, piling them layer by layer; start watering at the fourth layer, and from the fourth layer to the eighth layer add all of the cake fertilizer, superphosphate, gypsum and half the amount of urea layer by layer. After building 10 layers, the heap height reaches about 1.5 m, the four sides are basically vertical, the top of the heap is shaped like a turtle shell, and the very top is covered with 1 layer of manure. To maintain aeration, 2-3 ventilation holes can be inserted from top to bottom with bamboo tubes at the top of the compost heap. To keep warm and retain moisture, the top of the heap should be covered with straw mats, and plastic film should be used on rainy days. When piling the material, the water content of the compost is required to reach saturation. On the second day after building the heap, measure the material temperature within 50 cm; under normal conditions the material temperature will rise to 70°C. If it does not reach this temperature, find out the cause and take remedial measures as soon as possible. During fermentation, turn the heap once at intervals, supplement auxiliary raw materials, and adjust the water content and pH of the compost. On the second day after building the heap, the material temperature begins to rise, and on the third day the temperature at the center of the heap reaches its highest point (74-80°C). When this temperature is reached, the first turning can be carried out 6-7 days after building the heap. On the day before turning, water the upper part of the heap first, then water layer by layer during turning; after the heap is rebuilt, a small amount of water should flow out around it, indicating that the amount of water added is appropriate. When building the heap, still add the remaining urea from the fourth layer to the eighth layer. 2 days after the first turning, the material temperature can reach as high as 75-80°C. 5-6 days after the first turning, carry out the second turning. The focus of the second turning is to adjust moisture; the appropriate water content is when the compost is squeezed tightly by hand and 3-4 drops of water can be squeezed out. On rainy days, when covering with plastic sheeting, prop it up with wooden sticks so that the inside of the material is ventilated, prevent anaerobic fermentation, and keep the material temperature at 60-65°C. Generally, the third turning can be carried out 4-5 days after the second turning, using the same method as above. If there are lumps of manure, crush them before mixing them in. 4 days after the third turning, carry out the fourth turning. First check the water content of the heap; the method is that when the compost is squeezed tightly by hand, 1-2 drops of water between the fingers is just right. If the moisture is insufficient, adjust it with 1% lime water. If the moisture is too high, spread it out to air for a while first, and rebuild the heap when the moisture is appropriate. At the same time, prepare 0.5% dichlorvos and spray it to kill insects. 3-4 days after the fourth turning, the temperature inside the material is still around 50°C and tends to stabilize; carry out the final turning. During the turning, adjust the water content of the compost to 60%-63% and the pH to 7.5-8.0, and at the same time check whether residual ammonia gas and pests remain in the compost. If there is an ammonia smell, formaldehyde can be used again to neutralize it; if there are insects, 0.5% dichlorvos can be used to kill them. From heap building to entering the house, the compost generally needs to be turned 4-5 times, and the intervals between turnings are usually 7, 6, 5, 4 and 3 days. During the heap-building process, the moisture of the compost should first be wet and then dry, the heap should first be large and then small, and the turning intervals should first be long and then short. Following this principle, the heap temperature can be maintained above 50°C for a long time.

Detailed Guide to Processing Technology for a Series of Potato Snack Foods
Potatoes have rich nutritional value. They contain protein, phosphorus, iron, inorganic salts, vitamins B1 and B2, and carotene, and their protein quality is relatively good, closest to animal protein, and easy for the human body to absorb. According to determination with an amino acid analyzer, potatoes contain 18 kinds of amino acids required by the human body and various trace elements. Potatoes can also supply the human body with a large amount of mucoprotein. Mucoprotein is a mixture of polysaccharides and proteins, can prevent fat deposition in the cardiovascular system, maintain the elasticity of arterial blood vessels, and prevent
