Embodiment Construction

[0022] According to the aforementioned breeding and cultivation methods, the yield per mu of "Baonong 34" is stable at 550kg--600kg after multi-point trial planting, testing and demonstration. For example, in 2000, a breeding farm of fine varieties produced trial varieties, with an average yield of 562kg per mu. In 2001, 31 mu were bred per plant, with an average yield of 565kg per mu. In 2001, a township tried to plant 6.5 mu of direct-seeding rice, with an average yield of 520kg per mu. In 2002, a farmer in Shanghai tried to plant 2.4 mu, with an average yield of 585kg per mu. An agricultural company tried to plant 8 mu, with an average yield of 615kg per mu. A township’s fine seed farm planted 7 mu of direct-seeding rice, with an average yield of 527kg per mu. mu, with an average yield of 593kg per mu. In 2002, the average yield per mu was 583kg in Shanghai city trial, 566kg per mu in Baoshan District, 561kg per mu in production test, and 573kg in average yield per mu in ...

Abstract

The invention discloses a seed selection and cultivation method for Baonong 34, a novel rice variety, wherein the seed selection step employs the parental generation combination of short stem round-grained rice Hanfeng and the characteristic fragrant glutinous rice Kouxianghong, and the breeding step comprises choosing pollen growth time, low-temperature and sterilization treatment, increasing lattice curing rate, improving green sprout rate and secondary transplanting.

Description

technical field [0001] The invention belongs to the technical field of agricultural improved varieties, and in particular relates to a method for breeding and cultivating a high-quality rice "Baonong 34". Background technique [0002] The breeding of improved agricultural varieties is the basic way to increase crop yield and improve crop quality. The breeding and cultivation of improved agricultural varieties are closely related to natural conditions such as geography and climate. Carrying out crop variety improvement according to local conditions has become an important issue in the development of agriculture. All countries and regions have invested considerable manpower and material resources to carry out relevant scientific research. [0003] Rice is the most important food crop in my country. Our country has a vast territory and abundant resources, and the natural conditions vary greatly from place to place. East China, such as Shanghai, Jiangsu, Zhejiang and Anhui, h...
