Rice straw return technology is being vigorously promoted and applied.
Vigorously promoting rice straw return is one of the most economical and effective ways to recycle nutrients through the soil-crop-soil cycle. It not only plays a very important role in improving soil and building up soil fertility, but also has great significance for improving soil potassium and silicon nutrient conditions, balancing crop nutrition, and alleviating the contradiction between the shortage of potassium fertilizer resources in our country and the excessively rapid rise in chemical fertilizer prices. 1. Increasing soil organic matter content. Rice straw has a high organic matter content. Generally, dry rice straw has an organic matter content of 40%. After being returned to the field, it is beneficial to the

Detailed Explanation of the Five Major Characteristics of the Rice-Rapeseed Combined Planting Model
Rapeseed is an important oil crop in the Yangtze River Basin. Traditional rapeseed cultivation involves raising seedlings and transplanting them. Because raising seedlings and transplanting rapeseed in paddy fields requires large inputs of labor and materials, with low yields and low returns, and crops are easily lost when unsuitable weather occurs, this affects farmers' enthusiasm for planting rapeseed. Changing traditional seedling transplanting to no-till broadcast direct seeding with rice straw mulching simplifies the production process and achieves the goal of cost saving and efficiency improvement. Compared with traditional seedling transplanting, the rice-rapeseed combined model has the following characteristics: First, no-till broadcast direct-seeded rapeseed, per

Key Cultivation Techniques for the Rice-Rice-Oilseed Rape Triple Cropping System
No-Till Direct Seeding Technique for Oilseed Rape in Paddy Fields The no-till direct seeding technique for oilseed rape in paddy fields is a cultivation method in which oilseed rape is sown directly without plowing after the previous rice crop is harvested. This technique features full utilization of temperature and light resources, improved land utilization rate, reduced labor intensity, and significant economic benefits. Based on demonstration planting results, this technique is suitable for large-scale promotion in our county. I. Four Major Advantages of No-Till Direct Seeding of Oilseed Rape: 1. Labor-saving and cost-saving. For one mu of paddy field, the labor required for ditching, fertilizing, sowing, and pesticide application is only 2-3 working days; the cost of seeds, fertilizers, and pesticides does not exceed 100 yuan

Detailed Introduction to Biological Water-Saving Technology in Rice
Biological water-saving technology refers to the use of a plant's own physiological and genetic potential to obtain more output under the same water conditions. Although it is difficult to research and remains underdeveloped, it requires little input and yields high benefits in practice. Using the large amount of germplasm resources obtained over many years, rice breeders have developed a number of strongly drought-resistant varieties through intervarietal hybridization, systematic selection, and introduction and evaluation, and have applied genetic engineering to the breeding of new varieties, continuously providing high-quality, strongly drought-resistant new hybrid rice combinations and new varieties with greater biological potential for water-saving cultivation.

Application methods of Shangnong Iprobenfos for controlling rice blast
Shangnong Iprobenfos is a systemic fungicide with a pre-harvest interval of more than 20 days and low toxicity to humans and livestock. Its formulation is a 40% emulsifiable concentrate. Shangnong Iprobenfos is mainly used to control rice neck blast, and is also effective against rice sheath blight (small sclerotium disease), small grain sclerotium disease, rice sheath blight, and planthoppers, and also has insecticidal and lodging-resistant effects. Application methods: To control rice blast, sheath blight, and small sclerotium disease, dilute 600-1200 times with water and spray. Precautions: (1) This agent is also a cotton defoliant, so when applying

Analysis of the Benefits of Rice-Water Bamboo Crop Rotation and Water Bamboo Cultivation Techniques
Chongxian Town, Yuhang District, Hangzhou City, is located in a plain water-network area and was originally mainly engaged in rice cultivation, along with some aquatic crops such as water bamboo, arrowhead, and lotus root. During agricultural development and industrial restructuring, Chongxian Town utilized local water and soil resources to vigorously expand the rice-water bamboo rotation area, and treated water bamboo production as a high-efficiency agricultural undertaking within the vegetable basket project. The district, town, and village invested 2 million yuan to establish the Chongxian Village water bamboo demonstration park. In 2005, the Hangzhou Municipal Agricultural Comprehensive Development Office designated it as a national agricultural comprehensive development high-tech demonstration

Detailed Introduction to the Fengdao No. 15 Rice Variety
Fengdao No. 15 is a new early-maturing japonica rice variety bred by the Dali Prefecture Agricultural Science Institute through crossbreeding, with 04-2865 as the female parent and the high-yielding variety Dianyul No. 1 as the male parent. Results from years of multi-site trials and demonstrations show that the standout characteristics of this variety are early maturity, strong cold tolerance, moderate resistance to rice blast and bacterial leaf blight, high and stable yield, and good quality. It is currently a new japonica rice variety with relatively outstanding comprehensive traits among the promoted varieties in the high-altitude areas of Yunnan Province. In July 2002, it passed the approval of the Yunnan Provincial Crop Variety Approval Committee, and it was determined to be promoted for planting in the cold cool rice areas of Yunnan Province at altitudes above
