Embodiment 1

[0070] In the high-altitude mountainous area of ​​northwestern Yunnan where one crop is ripe once a year, 10 and 1 local fodder oat varieties were introduced to the winter fallow land by means of crop rotation for comparative experiments, and 7 fodder oat varieties suitable for planting in winter fallow land at an altitude of 2200 meters were screened out. , New winter and spring forage varieties in high-altitude areas have been added, which has completely changed the situation of single planting varieties in winter fallow land in the city; the cultivation range of winter and spring forage grass has been expanded, high-quality and high-yield forage grass sources have been widely opened, and the shortage of high-quality forage grass has been solved. question;

[0071] (1) The specific steps are:

[0072] 1. Land plot selection Choose flat terrain or small slope, deep soil layer, good irrigation and drainage, and must have irrigation conditions, but it is strictly forbidden to c...

Abstract

The invention belongs to the technical field of fodder oat cultivation, and discloses a cultivation and management method for fodder oat in a winter idle land of a high-altitude area. The method comprises the following steps: plot selection; land preparation and fertilization, wherein 1 to 1.5 tons of decomposed farmyard manure, 5kg of urea and 15-20kg of compound fertilizer are applied on the surface of the land per mu before tilling, tilling for soil breaking is performed then, raking and land leveling are carried out, and the depth thereof is 10-15cm; a variety is best selected from imported hulled oat varieties which are resistant to cold and drought, strong in resistance to plant diseases and insect pests and high in grass yield; sowing and pressing, wherein sowing in strip is adopted, line spacing is 15-20cm, and a covering depth is 3cm or so; the sowing quantity is 8-9kg / mu; adoption of broadcast sowing, wherein a rotary tiller is used to cause seeds to be spun into the soil 3cmor so after sowing, and the sowing time is from mid-late October to early November; pressing treatment is performed after sowing; field management; pest control; and harvest. The invention provides ahigh-yield cultivation and management method for producing single-season high-quality fodder oat by utilizing the winter idle land after cropping in the high-altitude area of northwest Yunnan.

Description

technical field [0001] The invention belongs to the technical field of fodder oat cultivation, and in particular relates to a method for cultivating and managing fodder oats in fallow fields in high altitude areas. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Lijiang City is located in the northwest of Yunnan, the middle and upper reaches of the Jinsha River, and the Yunnan-Sichuan-Tibet Triangle in the transition zone from the Qinghai-Tibet Plateau to the Yunnan-Guizhou Plateau. The territory has towering mountains, deep canyons, and undulating rivers. It is distinct (more precipitation in summer and autumn, less in winter and spring), large temperature difference between day and night, and long frost period in winter. Lijiang's agricultural infrastructure is weak, and agricultural production depends on natural planting. Due to the constraints of terrain, climate, altitude and other factors, crop...
