Disease- and pest-resistant japonica rice successfully bred in Jiangsu
A breakthrough has been achieved in the "Breeding of New Multi-Resistant, High-Yield and High-Quality Japonica Rice Varieties" carried out through cooperation between the Bokun Agricultural Research Institute of Yixing City, Jiangsu Province, and the China National Rice Research Institute and other institutions. New high-yield, high-quality japonica rice lines such as 4701 and 4714 have been successfully bred with resistance to brown planthopper, rice blast and other pests and diseases. It is reported that the bred high-yield, high-quality japonica rice lines combine genes for resistance to brown planthopper, white-backed planthopper, rice blast and stripe leaf blight, as well as specific genes for high yield and high quality. Testing has shown that these high-quality japonica rice lines are resistant to brown planthopper,

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

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 Functions and Roles of Rice Leaves
The rice leaf is composed of two main parts: the leaf blade and the leaf sheath, in addition to accessory organs such as the auricle and ligule. The junction where the leaf sheath connects to the stem is called the leaf node. The junction where the leaf sheath connects to the leaf blade is called the leaf collar. When the seed germinates, the first thing to grow out is the coleoptile that protects the young shoot as it emerges, also called the sheath leaf. The sheath leaf differs from other leaves in that it is white and shaped like a cylinder. The second leaf has only a leaf sheath and no leaf blade, and is called an incomplete leaf. Leaves beginning from the third node have both a leaf sheath and a leaf blade, and are called complete leaves. Counting the number of leaves of a variety
