How is the Changnongjing No. 2 rice variety?
The new rice variety "Changnongjing No. 2" (formerly named 89-94) was developed by the Changshu City Institute of Agricultural Sciences in Jiangsu Province in 1989 through a double cross of 84G091/Xiushui 04//Wuyujing No. 2, followed by continuous non-greenhouse generation advancement of F1 and F2, and was bred in 1993 as a new medium-maturing late japonica variety. This line has the characteristics of excellent grain quality, high yield, early maturity and good adaptability. Characteristics: This variety has large panicles and large grains, a low sterility rate and a high 1000-grain weight. It is a large-panicle type variety, similar to hybrid japonica rice. The usual yield is more than 650 kg per mu, with

How to prevent and control rice diseases? Kejie Town in Changning County strengthens unified prevention and control
In June, continuous rainfall in Kejie Town, Changning County, caused bacterial leaf streak to occur to varying degrees in more than 8,000 mu of high-quality rice across the town. The town quickly organized agricultural science personnel, taking villages as units and focusing on high-quality rice demonstration plots, assigning two technicians from each village to go deep into farming households to provide scientific and technological guidance, fully launching a wave of unified prevention and control of rice, mainly targeting bacterial leaf streak. At the same time, a 200-mu high-quality rice demonstration area was established in the two villages of Kejie and Dadi, with 20 yuan per mu in unified prevention and control subsidy funds, and electric sprayers were used uniformly for prevention and control. As of

Will rice suffer from quinclorac phytotoxicity after reseeding
Question: 4 mu of direct-seeded rice is at the 3-leaf 1-heart stage. Very few seedlings emerged after sowing, there are no seedlings in the low-lying areas, and the emergence rate is less than 50%. The sowing rate was 7-7.5 kg per mu. Not long ago, quinclorac was used for the "second kill" weed control. May I ask, if rice is reseeded in the areas of this field where no seedlings emerged, will the reseeded rice suffer from quinclorac phytotoxicity? Answer: Quinclorac is a selective herbicide for controlling barnyardgrass in paddy fields. It is generally applied at the 2-leaf 1-heart stage of rice, and applying it too early easily causes phytotoxicity. Before the 1-leaf stage of the seedlings, especially at the needle standing stage, applying quinclorac at the conventional rate

Introduction to the Rice Variety Boyou Gan 28
[Basic Information] Boyou Gan 28 (Boyou 752) is a medium-late, late-maturing combination bred by the Rice Research Institute of the Jiangxi Academy of Agricultural Sciences by crossing the male-sterile line Bo A with the self-selected restorer line 752. In spring in Hainan, test crosses were made using the Guangxi male-sterile line Bo A with the strong restorer line 752 (selected from 26 Zhai Zao/BG910) bred by this research group; in the autumn of the same year, a heterosis comparison trial was conducted in the institute's experimental field. The result was outstanding yield, with a measured yield of 102 t/hm2, 9.9% higher than Shanyou 63. Boyou Gan 28 1
