Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

Detailed introduction to the rice variety Guyou No. 14
After the "father of hybrid rice" Yuan Longping bred hybrid rice in the 1970s, the world experienced a second Green Revolution. However, hybrid rice seed production procedures are complicated and expensive, and there are many fake seeds on the market. How to breed apomictic rice that can be used as seed generation after generation became the long-cherished wish of many breeders. Now, apomictic rice bred by researcher Chen Jiansan, a famous breeder at the Chinese Academy of Agricultural Sciences, and other experts has realized this wish. The biggest features of apomictic rice: besides not needing annual seed production, it has also made great breakthroughs in rice quality, yield and resistance

Four key points to master in rice fertilization
First, pay attention to applying sufficient organic fertilizer. Organic fertilizer contains various nutrients, can improve soil aeration and its characteristics of absorbing fertilizer and retaining water, promote robust growth of rice plants, and achieve high yield and good quality. Organic fertilizer is mainly used as base fertilizer, applying 30-40 loads of decomposed farmyard manure per mu, or 30-40 kg of cake fertilizer, and 40-50 loads of human and livestock manure can also be applied after plowing and before flooding. Second, pay attention to controlling nitrogen fertilizer. Excessive application of nitrogen fertilizer to rice will not only cause an increase in ineffective tillering, greening, lodging, and intensified pests and diseases, leading to more empty and shriveled grains, a decline in the seed-setting rate, and affecting rice yield.

Characteristics and Traits of the Rice Variety Guofeng No. 1
Origin: A new high-quality three-line hybrid rice variety bred by the Guofeng High-Quality Hybrid Rice Breeding Center (a joint venture between Hefei Fengle Seed Industry and the China National Rice Research Institute). Approval status: Approved by the National Approval Committee in 2001. Characteristics and traits: When grown as double-season late rice, the growth period is similar to that of Jinyou Gui 99; when grown as single-season middle rice, the growth period is about 6 days shorter than that of Shanyou 63. This combination has taller plants, medium tillering ability, and longer flag leaves, with large panicles and many grains, generally 180 total grains per panicle, and a seed-setting rate of 8

What are the common problems in dryland rice cultivation?
1. How to grow enough rice seedlings under drought and water shortage conditions. The whole year's success lies in spring. This vividly and profoundly illustrates the importance of seedling raising in the whole year's production. Under this year's special conditions, growing enough seedlings is the key measure to win the battle against drought and secure a bumper harvest. To grow enough rice seedlings under drought and water shortage conditions, the first thing is to determine the seedling raising method according to local conditions, and the second is to implement the seedling raising technical measures. When determining the seedling raising method, there are three approaches to choose from for reference: first, in places where water can be obtained locally, promote
