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

The role and application method of spraying paclobutrazol on rice
Paclobutrazol is a highly active plant growth retardant and broad-spectrum fungicide. Its internationally used code is pp333, and the code for the product made in China is MET. Its physiological effects on rice are mainly dwarfing, promoting tillering and improving stress resistance. Moreover, after transplanting, the seedlings turn green quickly, tiller early, the number of effective panicles increases, and the seed-setting rate and 1000-grain weight increase. It is a simple, easy and effective measure to increase yield. Experiments in various places in Liaoning in recent years have found that rice seedlings sprayed with paclobutrazol show the following changes compared with the control: 1. The seedlings become shorter. Spraying at the rice seedling stage

Winter control of rice pests and diseases can yield twice the result with half the effort
In winter, rice pests and diseases are in a dormant state: pests stop feeding and pathogens stop infecting. If farmers seize this favorable opportunity to carry out control, they can achieve twice the result with half the effort. 1. Dispose of diseased rice straw. Diseased straw is the overwintering site for the pathogens of rice bacterial leaf streak, bacterial blight, rice blast and many other diseases, and is the main source of infection the following year. Before the end of March, farmers can compost diseased straw at high temperature, or process it as feed or fuel, which can greatly reduce the number of pathogens. For diseased rice straw that cannot be fully processed before the end of March,
