Forage grass type triticale intercropping type multi-cropping mode in region around lakes on Qinghai-Tibet Plateau and Gannan region

Abstract

The invention relates to a forage grass type triticale intercropping type multi-cropping mode in the region around lakes on the Qinghai-Tibet Plateau and the Gannan region. The method comprises the following steps of 1, after sowing land is fertilized, through ploughing and harrowing, making land level in the region with the latitude lower than 3,500 meters, including all the three prefectures ofnorth Qinghai, south Qinghai and Malho, Tianjun county in Haixi Prefecture, the eastern sector of Qilian Mountains in Gansu, the region around lakes on the Qinghai-Tibet Plateau in Gannan Prefecture and the Gannan region; 2, conducting row planting on preceding crops Gannong II triticale in the first and middle ten days in September every year, and after sowing, conducting furrowing; 3, conductingtopdressing after the preceding crops are sowed and turn green in the middle ten days in March next year; 4, conducting row planting on the multi-cropped crops among lines of the preceding crops in the middle ten days in May next year; 5, when the previous crops and the multi-cropped crops all enter a flowering period, using labor or a hilly area mower to cut the triticale. By implementing the triticale intercropping type multi-cropping technology in the region around lakes on the Qinghai-Tibet Plateau and the Gannan region, a double-cropping-a-year planting mode is created, and the triticaleyield and economic benefit in a unit area are increased by a large margin.

Description

technical field [0001] The invention relates to the technical field of forage grass production, in particular to a forage grass type triticale intercropping multiple cropping model in the Qinghai-Tibet Plateau around the lake and the Gannan area. Background technique [0002] Multiple cropping refers to the method of planting two or more crops in one year on the same land. Compared with single cropping, multiple cropping has obvious advantages. It changes the input types of variable elements through techniques such as expanding the sown area, increasing the yield of crops in each season, and planting multiple crops rationally, so as to avoid the continuous decline of single variable elements. (Li Tianlai, Yang Lijuan. Overcoming crop continuous cropping obstacles-a difficult problem [J]. Chinese Agricultural Sciences, 2016, 5: 916-918.). Multiple cropping mainly achieves the goals of high light efficiency, high land efficiency, high energy consumption, high input and high o...

Problems solved by technology

This area is the most suitable area on the Qinghai-Tibet Plateau for large-scale contiguous planting of forage grass and mechanized operations. However, due to the cold climate in this area, annual forage forage crops such as oats, highland barley, rye, arrowhead peas, and Chinese sweet potato a
