Breeding of Xuanjingnuo No.7 and high-yield cultivation techniques for rice following wheat
This article introduced the breeding process and characteristic characteristics of Xuanjingnuo No.7,and summarized the high-yield cultivation techniques as a wheat stubble rice from two cultivation models:machine transplanting and live broadcasting. Xuanjingnuo No.7 was an early maturing and late maturing glutinous rice variety developed through systematic breeding using Xuanjingnuo No.1 as the female parent and Jingnuo 86120-5 as the male parent. It had characteristics such as tolerance to late sowing,strong stress resistance,and wide adaptability,and was suitable for machine transplanting and direct seeding as wheat stubble rice cultivation. The principle of high-yield cultivation was to promote strong stems,large panicles,and increased grain weight on the basis of sufficient effective panicles,in conjunction with disease,insect,and weed control. Specific measures include timely and appropriate sowing,scientific fertilizer and water management,comprehensive prevention and control of diseases,pests and weeds,and timely harvesting. Machine transplanting also requires uniform planting and dense planting,and sufficient planting of basic seedlings. The purpose was to provide reference for the promotion and planting of this variety.
