  • Detailed Introduction to the Rice Variety Jinzhu No. 1

    "Jinzhu No. 1" is a new medium-late rice variety developed through systematic selection, variety comparison, and regional trials by Niu Jing, a researcher at the Tianjin Academy of Agricultural Sciences and a Tianjin-appointed rice breeding expert, and his team. It is the first new variety in China developed through indica-japonica hybridization with major promotion value. It passed achievement appraisal in 1992. This variety is of the japonica type, with a full growth period of 150 days in the Beijing-Tianjin region, a seedling bed period of 35-40 days, and a main field period of 110-105 days. Seedling growth is relatively vigorous with a well-developed root system. The main stem has 15 leaves, plant height 90-10

  • Detailed Explanation of Upland Rice Cultivation Techniques: From Sowing to Field Management Key Points

    Upland rice refers to the practice, under dryland conditions, of selecting high-quality rice varieties with relatively strong drought tolerance, adopting dry direct seeding, relying mainly on natural rainfall throughout the growth period, and appropriately supplementing water during drought in key growth stages, so that rice can grow and develop normally and flower and set seed under relatively moist soil conditions. The key points of upland rice cultivation techniques are introduced as follows: 1. Variety selection. Because the sowing period of upland rice is later than the seedling-raising period of paddy rice, varieties with early maturity should be considered in variety selection. Recently approved at the national level in our province

  • Rice Pest and Disease Control: What to Do When Rice Has Difficulty Heading?

    What should be done when rice has difficulty heading? What causes difficulty in heading in rice? Please provide guidance. Causes of difficulty in heading in rice: When rice has difficulty heading, or shows the "neck-enclosed" phenomenon, the grains enclosed within the leaf sheath generally become empty or shriveled grains because they cannot emerge in time to pollinate and fertilize, which has a major impact on yield....

  • Characteristics and Traits of the Rice Variety Huayou Gui 99

    [Basic Information] The promotion of hybrid rice has played an important role in increasing China's grain production. With the development of the national economy and the continuous improvement of people's living standards, the requirements for grain quality have become increasingly higher. Breeding early indica hybrid rice combinations with good quality, high yield, and disease resistance is an important issue urgently needing to be solved in current rice breeding. The Department of Agronomy of South China Agricultural University, in collaboration with Tengxian Seed Company and Raoping County Seed Company, used the high-quality male sterile line Y Huanong A, which is highly resistant to rice blast, and the restorer line Gui 99 to develop the high-quality, high-yield, rice blast-resistant South China early indica hybrid rice

  • Detailed Explanation of the Principles and Key Technologies of the Three-Super Cultivation of Rice in Cold Regions

    The Three-Super cultivation technology for rice in cold regions addresses the growth-limiting factors currently present in high-yield rice cultivation in cold regions, such as a short growth period, excessive basic seedlings, excessive consumption of growth, poor light-receiving posture of the plant type, and decline of late-stage growth. Taking the "ridge-edge rice cultivation effect" as a model, it takes creating the largest super-high-yield population with the fewest basic seedlings as its basic approach, and takes "extending and expanding the nutritional time and space, releasing production potential, and strengthening the dual canopy (plant canopy and root canopy) performance" as its basic principle. It adopts standard high-quality super rice, uses single (double) seed positioning with ultra-early, ultra-low-rate sowing

  • Yesizhan: Main Agronomic Traits and High-Yield Cultivation Techniques of a High-Quality Conventional Rice

    Yesizhan is a temperature-sensitive, early- and late-season dual-purpose, high-quality, high-yield variety bred by the Foshan Institute of Agricultural Sciences through sexual hybridization of Xiyepzhan 10 and Zhong'er Ruanzhan, and was approved by the Crop Variety Approval Committee of Guangdong Province in March 2005. Its main agronomic traits and high-yield cultivation techniques are introduced as follows: 1 Main agronomic traits. Yesizhan is early to mid-early maturing in the early season, with an average full growth period of 127 days; it is early maturing in the late season, with an average full growth period of 108 days. The plant is short and sturdy, with strong tillering ability, green leaf color, narrow and upright leaves, and the capacity to hold many panicles, with large panicles and dense grains, and good grain filling

  • 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

  • Control Methods for the Brown Planthopper Infestation in Rice

    The brown planthopper, also known as the brown rice planthopper, is commonly called ascarid worm, soft-shelled ascarid, yóu worm, and midge. Scientific name Nilaparvata lugens (Stdl), order Homoptera, family Delphacidae. The brown planthopper is one of the major pests of rice in China, causing damage in all major rice-growing regions across the country, north and south, and every year it occurs and causes damage mixed with the white-backed planthopper. The two planthoppers...
