Xinjiang’s efficient cotton and peanut rotation planting technology demonstration successful
“This experimental field is planted using a ‘new’ technology – ‘cotton and peanut rotation’. Peanuts are harvested through a segmented harvesting model, that is, they are first pulled up and then picked, and each peanut plant bears fruit. The peanut pods are full and the soil is shaken off… This means that Xinjiang’s cotton and peanut efficient rotation planting technology has been successfully demonstrated.” Li Qiang, director of the Xinjiang Comprehensive Experiment Station of the National Peanut Industry System and a researcher at the Economic Crops Research Institute of the Xinjiang Academy of Agricultural Sciences, said on the 8th .
In recent years, relying on the Xinjiang Comprehensive Experimental Station Project of the National Peanut Industry System, the Xinjiang Major Science and Technology Project “Research on Key Technologies for Oil Crop Germplasm Resource Collection and Excellent Gene Mining” and other projects, the Xinjiang Academy of Agricultural Sciences Economic Crops Research Institute has innovated the peanut industry system The team established a high-efficiency rotation planting technology for cotton and peanuts to promote “cost-saving, efficiency-increasing, and green ecology” of cotton oil production.
Li Qiang introduced that the experimental field covers an area of 32 acres, with more than 750 resource materials and about 40 new varieties (lines). Among them, there are 7 acres of cotton and peanut rotation experiments. Currently, the experimental field has entered the harvesting stage.
Currently, Li Qiang leads the team to run between the fields and the laboratory every day to obtain more detailed experimental data. Li Qiang said: “Xinjiang is China’s main cotton producing area and a high-quality cotton producing area. Cotton production occupies a leading advantage in the agricultural industrial structure. However, due to the widespread phenomenon of continuous cotton cropping, the soil environment has deteriorated, and cotton yield and quality have been affected to a certain extent.”
Li Qiang said that a large amount of experimental data shows that in peanut-cotton rotation, peanut roots and rhizobia coexist symbiotically, and about one-third of the nitrogen fixed by rhizobia remains in the soil, which can not only fertilize the soil and provide nutrients for the next crop, but also It has a positive effect on alleviating diseases and reducing the use of pesticides and fertilizers, promoting cotton oil income, achieving land use coordination and improving economic and ecological benefits.
“Next, the team will conduct demonstration and promotion in Xinjiang to allow this new technology to ‘take off’.” Li Qiang said.
