Abstract

The invention provides a Shanlan rice dwarfing high-yield planting method. The method includes steps: applying base fertilizer, ridging, drying seeds in the sun, soaking the seeds, sowing, weeding, dwarfing, managing a rice field, and preventing pest and disease. High-quality seed soaking liquid is selected to perform proper-temperature seed soaking and variable-temperature seed soaking on the seeds, sowing density is adjusted by means of broadcast sowing, and a method combining weeding management, proper-time fertilization and using of biological insecticide to control pest and disease is adopted, so that inter-node length is shortened, Shanlan rice plant height is lowered, stem thickness and strength are improved, lodging resistance is improved remarkably, and ear length is increased. The planting method is high in operability, easy for mass peasants to master and great in popularization and application value.

Description

technical field

[0001] The invention relates to the technical field of agricultural planting, in particular to a dwarf and high-yield planting method of orchid rice. Background technique

[0002] Shanlan rice (Oryza sativa L.) is an ancient upland rice variety with strong adaptability in Hainan. Shanlan rice has strong drought resistance, white rice, strong stickiness and delicious aroma, and high crude protein content; Shanlan wine brewed from it has a very sweet taste and is well-known at home and abroad. However, Shanlan rice has poor tillering ability, low seed setting rate, poor plant type, and high plant height, generally reaching 140 cm to 160 cm. It is easy to lodging, low yield, and difficult to carry out industrial development. Exploring the dwarf and high-yield planting method of Orchid orchid in Hainan is of great significance for promoting the industrialization of Orchid orchid in Hainan. Contents of the invention
