Robinia hispida is a salt-and-alkali-resistant woody flowering plant.
Robinia hispida, also known as Jiangnan locust, is a deciduous shrub in the genus Robinia of the Fabaceae family. Its stems, branchlets, pedicels and petioles all bear red bristly hairs, hence the name Robinia hispida. Its leaves resemble those of black locust (Robinia pseudoacacia), with alternate odd-pinnate compound leaves and broadly elliptical leaflets. The papilionaceous corolla is pink or purplish red. The flowering period is in May, and the pods mostly do not develop. For propagation of Robinia hispida, black locust is commonly used as rootstock for "cleft grafting". Generally, high-branch grafting is chosen. After surviving, it grows very quickly, and the crown spreads outward in an umbrella shape, bearing flowers all over the tree in the second year, which is very beautiful. Artificially, Robinia hispida can be made to bloom twice a year by

Breeding and Application of Tianfengyou 269, a High-Yield, High-Quality, Multi-Resistant Hybrid Indica Rice
1 Breeding Process Tianfengyou 269 (formerly named Yanyou 269) is a new high-yield, high-quality, multi-resistant three-line hybrid indica rice combination bred in 2002 by the Institute of Agricultural Sciences of the Coastal Region of Jiangsu, by crossing Tianfeng A, developed by the Guangdong Academy of Agricultural Sciences, with the restorer line Yanhui 269, which was self-bred by our institute. The self-bred restorer line Yanhui 269 was produced in the summer of 1995 by making a cross with Yanhui 559 as the female parent and Yanhui 469 (an intermediate material of our institute) as the male parent, obtaining 26 hybrid seeds, which were brought to Sanya, Hainan in the winter of the same year for planting

Honeysuckle: An Excellent Greening Plant That Is Both Medicinal and Pollution-Resistant
Honeysuckle is widely distributed in our country, from Liaoning in the north, Shaanxi in the west, Hunan in the south, to Yunnan and Guizhou in the southwest. It is a woody vine, evergreen, fragrant flower that grows wild in the mountains and is widely cultivated in gardens. In small courtyards, they can climb walls and reach into the air, expanding green coverage; in summer they also bring fragrance throughout the courtyard, which can ease the restlessness of summer heat. Honeysuckle belongs to the genus Lonicera in the family Caprifoliaceae. Its paired, inch-long tubular axillary flowers bloom side by side; when they first open, both stamens and petals are white, as white as jade, and after two or three days they

Detailed Explanation of Key Points for Cold-Resistant Cultivation Techniques of Jujube Trees
Jujube cultivation in Liaoning Province is mainly concentrated in the Chaoyang, Huludao and Jinzhou areas. In recent years, the high price of jujube, especially the high returns from superior new varieties, has driven many growers in many areas to successively introduce and plant on a large scale, but most failed due to freeze damage. New development areas are limited to Dalian and Yingkou, and the varieties are only Pear Jujube, Jinling Round Jujube and the like. Other areas still have scattered courtyard plantings, and mostly with old varieties. To enable better development of jujube production in Liaoning Province, the author believes that attention should be paid to cold-resistant cultivation of jujube. 1 Cold-resistant variety

Disease- and pest-resistant japonica rice successfully bred in Jiangsu
A breakthrough has been achieved in the "Breeding of New Multi-Resistant, High-Yield and High-Quality Japonica Rice Varieties" carried out through cooperation between the Bokun Agricultural Research Institute of Yixing City, Jiangsu Province, and the China National Rice Research Institute and other institutions. New high-yield, high-quality japonica rice lines such as 4701 and 4714 have been successfully bred with resistance to brown planthopper, rice blast and other pests and diseases. It is reported that the bred high-yield, high-quality japonica rice lines combine genes for resistance to brown planthopper, white-backed planthopper, rice blast and stripe leaf blight, as well as specific genes for high yield and high quality. Testing has shown that these high-quality japonica rice lines are resistant to brown planthopper,
