High-Efficiency Cultivation Experience of Interplanting Onions with Plastic-Film Peanuts
I. Raising Onion Seedlings. Sow onions around August 25 of the first year (for every mu of onions planted, 0.05 mu of seedlings is needed, with a seeding rate of 0.25 kg). 2-3 days before sowing, use 25% nitrofen to control weeds in the seedbed, and pay attention to controlling underground pests during the seedling stage. Before the soil freezes, dig a temporary planting trench near the seedbed that is 50 cm wide and 20 cm deep (spread a layer of sand in the trench), tie the onion seedlings into bundles, and plant them densely in the trench for temporary planting, cover the top tightly with fine sand, and add a cover of straw to prevent cold wind from entering and damaging the onion seedlings.

Detailed Explanation of Key Technical Points for Shrimp Fry Stocking in Spring
1. After thorough pond disinfection, it is essential to splash Jiedu Lvshuibao or Hushui Jiedu Wang to neutralize and expel toxins. After 4 hours, splash compound Bacillus or Xinjunke combined with Heitujing over the entire pond (they must be soaked in water 4 hours in advance). This decomposes disinfected animal carcasses and other organic debris and converts them into nutrients needed for algae growth, which helps cultivate algae and fertilize the water, and cultivate bacteria to maintain water quality. Then choose a sunny morning with ample sunlight to fertilize the water. If conditions permit, add 10 cm of fresh algae-containing water to introduce algae species, or use Duozaoyuan to supplement algae species. Before fertilizing the water, turn on the aerator to make the water flow, which is beneficial for algae reproduction and growth. Fertilization: soak Qiangxiao Peizao Gao, Feishui Kele or Yizao Yingyangsu, Feishui Lishengsu in water for 4 hours before splashing. For ponds where water fertilization has failed or does not work for a long time, after filling with water, first use Hushui Jiedu Wang and Heitujing to purify the water, then after 4 hours use the above water fertilization products with Duozaoyuan to fertilize the water.</p><p>2. Most Litopenaeus vannamei (Pacific white shrimp) farmers believe that the first batch of shrimp fry is the best, and they all ignore weather conditions in order to grab the first batch of fry, even stocking fry at lower temperatures. If strong winds and cooling weather occur within two days after stocking, causing a sudden drop in temperature, the shrimp will have a strong stress response. Because the fry are relatively weak, this can easily cause fry mortality. Therefore, stocking fry requires patience. Wait for consecutive good weather to stock fry, and choose a sunny morning or evening. Before stocking, use Jiedu Lvshuibao or Hushui Jiedu Wang to remove toxins from the water, and splash VC Yingjiling and Fuhe Gaibao to improve the fry's stress resistance and promote molting. 3. When selecting shrimp fry, understand the qualification, commercial reputation and technical strength of the hatchery enterprise, such as whether the production of broodstock and seedlings is standardized, whether it meets national requirements, and whether antibiotics are used or high-temperature seedling production is carried out throughout the production process. When purchasing fry, whether the enterprise can present quarantine qualification certificates from relevant government departments to ensure the health of the shrimp fry is the primary condition for successful farming. 4. Maintain the stability of pond water. Too lean or too fertile water will cause oxygen deficiency. Choose excellent water fertilization products such as Qiangxiao Peizao Gao, Jiaosu Gaifei, Yizao Yingyangsu, Feishui Kele, Feishui Lishengsu, Duozaoyuan, etc. to cultivate high-quality algae and keep the water body fertile, lively, tender and refreshing. When the water is too fertile and too dense, appropriately exchange part of the water, use Jiangjie Wang to improve water permeability, and use microecological preparations such as compound Bacillus, Xinjunke, pure EM bacteria, etc. to maintain the balance of algae and bacteria in the pond water. Regularly use Heitujing combined with compound Bacillus, Yingji Di Jiankang and other substrate improvers to keep the pond bottom clean and prevent moss, giving the shrimp a good bottom environment. 5. Feed reasonably. The feeding time is about 2 hours. Check the shrimp's feeding situation while they are eating to avoid leftover feed or insufficient feed. Regularly add health nutritional products such as Fengxia Gaowen C, Mianyi Huoliyuan, Hugan Weibao, Kaiwei Putang, etc. to the feed to improve the shrimp's feeding ability and the body's disease resistance, and improve the intestinal tract. Especially during the juvenile shrimp liver transition period, Hugan Weibao, Fengxia Gaowen C, Mianyi Huoliyuan, etc. should be added. 6. Use drugs reasonably. When shrimp become sick, according to the incidence situation and symptoms, use drugs safely under the guidance of technicians, and try to avoid using highly irritating drugs or antibiotics. It is recommended to usually splash herbal antibacterial and detoxifying traditional Chinese medicine products such as Caoben Jundumie for prevention, and at the same time pay attention to regulating water and improving the bottom, maintaining excellent water quality and substrate environment.</p>
