Detailed Introduction to the Hexi 40 Rice Variety
The Hexi 40 rice variety was developed through crossbreeding by the China-Japan Project Team of the Yunnan Academy of Agricultural Sciences. This variety has a plant height of 83.6 cm and a panicle length of 16.8 cm. It produces 5.6 tillers per plant, with a maximum of 12, and an effective panicle rate of 86.8%. The full growth period is 176--180 days, and heading and flowering finish in late July to early August, which helps it avoid the effects of low temperatures in August. It also shows early maturity, high yield, and disease resistance, with good-looking grain and excellent eating quality, as well as good overall traits. This variety can be suitable for altitudes of 19

Red rice paddy has been successfully cultivated in Hefei
After large-scale demonstration planting in Tongcheng, Huaining, Qianshan and other cities and counties, the new two-line hybrid rice (red rice) variety Wandao 129, independently bred by the Anqing Agricultural Science Research Institute, was recently examined and approved by the provincial crop variety approval committee; 9 of all 12 evaluation indicators reached the Ministry-issued first-grade high-quality rice standard, and it was decided to permit its promotion and planting as double-season late rice in the areas along the river and south of the river in our province. The newly bred red rice Wandao 129, also known as Peiliangyou 98, is a new rice variety that the Anqing Agricultural Science Research Institute began focusing on breeding in 1999

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

Demonstration and promotion of high-quality, high-yield rice for cold regions carried out in Heilongjiang
The National Agricultural Science and Technology Leap Program project "Integration and Demonstration of New High-Quality, High-Yield Rice Varieties for Cold Regions and Vegetative Matter Cultivation Technology" was officially launched on March 2 in Heilongjiang Province. The project is undertaken by the Heilongjiang Academy of Agricultural Sciences and Heilongjiang Bayi Agricultural University, and it is the first time that Heilongjiang Province's rice planting industry has been included in the National Leap Program. The project adopts three new high-quality, high-yield rice varieties of different maturity periods - Songjing No. 9, Longdao No. 5, and Longjing No. 14 - which were approved and promoted by the Heilongjiang Academy of Agricultural Sciences in the past two years and have passed national super rice acceptance, as well as vegetative matter pot seedling

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

Key Technical Points for Autumn Potato Cultivation with Rice Straw Mulching (Part 2)
4. Timely early sowing. Potatoes prefer a cool climate, and the sowing period should be when the daily average temperature steadily drops below 25°C. In plain and hilly areas below 500 m in altitude, the suitable sowing period is from late August to early September; in low mountainous areas at 500-800 m in altitude, the suitable sowing period is in late August. 5. Reasonable close planting and sufficient base fertilizer. For fields with rice stubble potatoes intercropped with rapeseed, both potatoes and rapeseed are planted in wide-narrow row patterns. For potatoes, the wide row is 0.6 m, the narrow row is 0.2 m, the hill spacing is 0.22 m, and about 700
