Rice Research Institute of Jilin Academy of Agricultural Sciences selects high-quality rice varieties
At the recently concluded evaluation of high-quality rice varieties (lines) in Jilin Province, "Jigeng 81" and "Jigeng 83", bred by the Rice Research Institute of the Jilin Academy of Agricultural Sciences, were rated as "high-quality rice varieties", and another 6 lines were rated as "high-quality rice lines". It is reported that this high-quality rice variety (line) evaluation was the third such event held after 1995 and 1998. The 10 high-quality rice varieties selected in the previous two events have already been promoted and applied on a large scale in production thanks to their good quality and high yield

=Rice Research Institute of the Jilin Academy of Agricultural Sciences Characteristics and Traits This variety has the following features: 1. It has good biological traits. The growth period is 135 days, requiring an effective accumulated temperature of about 2750°C, and it is insensitive to photoperiod and temperature responses. The plant height is 95-100 cm, the plant type is compact, the leaves are erect, and the leaf sheath, leaf margin, and leaf collar are all green. It has strong tillering ability, with more than 20 tillers per single transplanted seedling. -
What are the advanced methods for transplanting rice seedlings?
1. Improved intensive cultivation: transplant young seedlings at the 3-leaf to 4-leaf 1-heart stage early. Fields with good water sources should be planted early; fields with poor water sources can be planted slightly later. Both dry-raised and water-raised seedlings are suitable, but sufficient base fertilizer should be applied, the field should be deeply plowed and harrowed level, strong seedlings should be selected as much as possible, and transplanting should be done in shallow water; both the row spacing and hill spacing are 1 chi 3 cun, with three single plants per hill spaced 3 cun apart in a triangular arrangement. This transplanting method has density within sparseness and sparseness within density, minimizing competition among plants for nutrients and sunlight to the greatest extent, which benefits individual plant development and can therefore increase yield considerably. It is the most advocated

Introduction to the Characteristics of the Jijing 14 Rice Variety
The super-high-yield japonica rice new variety Jijing 14 (90-3) is an excellent new variety combining high yield, disease resistance, high lodging resistance, and superior grain quality. Characteristics: In the Hebei Provincial regional trials and large-area demonstrations, this variety's average yield per mu exceeded the control by more than 15%, with a general yield of 750 kg per mu. In 1993, this variety was selected to implement Hebei Province's "Harvest Cup" high-yield program. On-site expert threshing verification showed that the average yields per mu of two high-yield fields (over 2 mu each) were 907.9 kg and 918.7 kg respectively. Among them, 918.7 kg exceeded Hebei Province's

How should rice seedling beds be managed to cultivate strong seedlings?
I. Water management in seedling beds: For dry-raised seedlings, generally no supplemental water is needed during the seedling stage. Adhere to dry raising and dry management to improve the drought tolerance of the seedlings. At the same time, pay attention to watering well three times: water thoroughly with "bottom moisture water" before sowing, water well with "film-removal water" when removing the film, and water well with "leaf-rolling water" during drought. At the 1-2 leaf stage, control water appropriately to promote downward growth of seminal roots; at the 2-3 leaf stage, pay attention to supplemental water to prevent seedling death; after the 3-4 leaf stage, strictly control water and use dry raising to cultivate physiologically strong seedlings. To prevent excessive rainwater from making dry raising and dry management impossible, small arched sheds or greenhouses can be used to strictly control water for dry raising.

How effective is the Jiaduo frequency-vibration insect-killing lamp at trapping and killing the rice stem borer?
The rice stem borer is one of the important pests in rice production in Wuchang City. In recent years, with changes in rice varieties and warming climate conditions in our city, the occurrence and damage of the rice stem borer have become increasingly serious. According to this autumn's survey, for certain varieties in Wuchang, the average number of insects per 100 steps per mu reached more than 20,000, with the highest in key outbreak areas reaching 60,000, and in some cases more than 100,000. Such insect numbers are rare in history, whether domestically or abroad. In order to further control the damage of the rice stem borer, explore new approaches to its control, and reduce pesticide pollution of rice. This year our city set up at Sun Guanghao's field in Lianhua Village, Wuchang Town

Introduction to the Characteristics and Traits of the Jiahe Zaozhan Rice Variety
Jiahe Zaozhan was developed by the Rice Breeding Group of the School of Life Sciences at Xiamen University through a combination of sexual hybridization and the original "rice mature pollen irradiation mutagenesis technique" (which won the Second Prize for Science and Technology Progress of Fujian Province), and was bred through the pedigree method as Fujian Province's first late-maturing early-season new variety meeting the national quality standard for edible rice. It was recognized by the organizing committee of the '99 China International Agricultural Exhibition as a "Famous Brand Product" early-season variety and won the Second Prize for Science and Technology Progress of Xiamen City in 1999. Its cross combination: E94/Guangdong Dalizhong.
