New bamboo-rice varieties successfully bred at the Meizhou research base
Recently, the author learned from the bamboo-rice research base of the Meizhou Agricultural School in Meizhou City, Guangdong Province that various experiments on drought resistance, disease resistance and ratooning ability of bamboo rice will be carried out here this year, and scientific research on new varieties such as the special bamboo rice "bamboo purple rice" will also be launched. At the same time, bamboo rice 966 and bamboo rice 989 will continue regional trials across the province. Meizhou City has also set up 6 sites in Jiaoling, Meixian, Xingning and Wuhua counties and cities, totaling 300 mu, for trial demonstration planting of bamboo-rice cultivation techniques. The agricultural school has opened a test base to conduct drought-resistance tests on bamboo rice 966 and disease-resistance tests on bamboo rice 989.

Introduction to the Batai Red Fragrant Rice Variety and Its Characteristics
Batai Red Fragrant Rice was developed by the Zengcheng City Agricultural Science Research Institute in 1993 through mutation selection of the internationally renowned high-quality rice Basmati using concentrated solar radiation treatment in 1987. Production performance and grain quality characteristics: trial planting yielded 300-350 kg per mu. The grain surface is reddish-brown, and it is a fragrant soft-type rice. The slender grains contain a variety of trace elements, amino acids, vitamins and plant sterols needed by the human body, as well as flavonoid compounds; it is a medicinal rice variety (yet to be developed and utilized). Characteristics and traits: this variety's plant

The new high-quality indica rice variety Yuexiangzhan has the characteristic of a high harvest index
Yuexiangzhan is a "high harvest index type" conventional high-quality rice newly bred by the Rice Breeding High-Tech Research Laboratory of the Rice Research Institute of the Guangdong Academy of Agricultural Sciences. This variety passed the conventional regional trials for the early crop in 1996 and 1997 and the mixed regional trials of conventional early indica rice and hybrid rice in the South China rice region in 1997 and 1998. In February 1998, it passed the provincial variety approval of Guangdong Province for crop varieties. It has now become the control variety for the early-crop high-quality grain regional trial in Guangdong Province, a key variety promoted throughout the province, and has been included in a promotion project of the Ministry of Agriculture. Yuexiangzhan is a dual-purpose variety for both early and late crops. Its growth period for the early crop in Guangzhou is 125 days,

What are the reasons why rice seedlings are slow to tiller?
1. Rice bakanae disease: Disease pattern and transmission routes: The pathogen of rice bakanae disease overwinters on grains and rice straw. The following year, when diseased seeds or straw are used, the pathogen multiplies as the seeds germinate, invading through the seedling coleoptile or wounds, causing the seedlings to develop the disease and become leggy. Diseased seedlings often wither and die. Diseased seedlings that do not die are pale yellow-green, grow thin and elongated, generally about one-third taller than healthy seedlings; their roots develop poorly, with few tillers or even no tillering. After diseased seedlings are transplanted, they carry the pathogen to the field, causing rice plants to develop the disease. When rice heads and flowers
