Detailed Explanation of High-Efficiency Cultivation Techniques for Shallow-Water Lotus with Straw
High-efficiency cultivation of shallow-water lotus with straw has developed quite rapidly in Feixian County, Shandong Province over the past five years. In 2005, 8,870 lotus ponds were built, covering an area of more than 5,300 mu. The reason is that this technique has obvious advantages over traditional shallow-water lotus cultivation. Mainly, it has high yield and good benefits. The average yield per mu of shallow-water lotus cultivated with this technique is 4,923 kg, which is 1,242 kg more than the 3,681 kg of ordinary cultivation, an increase rate of 31%, and the quality is good with a high marketable rate, with a net increase in income of more than 1,800 yuan per mu.

High-yield and high-benefit "garlic with beans" planting achieves two plantings and three harvests
Interplanting garlic with soybeans is one of the resource-saving agricultural cultivation models currently promoted by the Fujin City Agricultural Technology Extension Center. It rationally matches and combines crops according to their growth patterns and habits, forming a mutually beneficial symbiotic relationship: the nitrogen fixation by soybean rhizobia increases the soil's nitrogen content, so the garlic does not suffer nutrient deficiency, which benefits the garlic's later growth and bulb enlargement. The garlic plants, especially the garlic roots, have a strong pungent taste in the soil, which strongly inhibits and kills various soybean pests, viruses and pathogens. Because

Introduction to famous and superior sweet potato varieties: these high-quality varieties are worth knowing about
Which sweet potato varieties to choose depends on market demand, what they will be used for, and also the local cultivation ecological conditions, especially soil-borne diseases. According to trials, virus-free cultivation generally increases yield by 20%-30%, and also improves their appearance and marketability. Therefore, choosing virus-free sweet potato elite varieties is the prerequisite for achieving high sweet potato yields. The overall goal is to select virus-free sweet potato varieties that are resistant to disasters and diseases, high-quality, high-yielding and efficient.

Detailed Explanation of Key Post-Season Management Techniques for High-Quality Wheat
After wheat turns green, sustained high temperatures and drought have caused the jointing, stem elongation, and flag leaf stages to occur 5-7 days earlier than usual. Currently, the wheat seedling condition is close to normal, but growth varies between plots. Therefore, it is recommended to strengthen the late-stage management of high-quality wheat: 1. Carry out booting and heading fertilization and irrigation management as soon as possible: this fertilization and irrigation can not only promote floret development, increase floret fertility rate and increase grain number per spike, but also promote nitrogen uptake and conversion in the later stage of wheat, making it one of the very important measures to increase wheat yield, protein content and wet gluten content (mandatory indicators for national standard strong-gluten wheat
