A planting method for intercropping of flue-cured tobacco and quinoa

Abstract

The invention relates to a planting method for intercropping of flue-cured tobacco and quinoa, belonging to the technical field of quinoa planting. The planting method comprises the following steps: planting land preparation, flue-cured tobacco planting management, quinoa seedling culturing, intercropping of the quinoa and the flue-cured tobacco, and field management for the quinoa after intercropping. According to the invention, tobacco planting, quinoa planting and soil protection are organically combined, and spare time and space of a tobacco area in autumn and winter are fully utilized forinterplanting the quinoa, so the utilization efficiency of land resources is effectively improved; the influence on soil hardening due to heavy fertilization during planting of preceding flue-cured tobacco is lightened; ecological pressure is retarded; ecological protection, soil improvement and economic development are simultaneously achieved; research and application demonstration sites for various planting techniques are established for ecological protection and sustainable development of the tobacco area and a poverty-stricken mountainous area; a theoretical basis is provided for the research on adjusting and controlling technologies for continuous cropping of tobacco, provides a scientific basis for realizing sustainable production of tobacco leaves, and has important practical significance on promoting modern tobacco production.

Description

technical field [0001] The invention belongs to the technical field of quinoa planting, and in particular relates to a planting method for the intercropping of flue-cured tobacco and quinoa. Background technique [0002] Quinoa (Chenopodium quinoa W.) is a dicotyledonous annual herb of the family Amaranthaceae. Native to the Andes in South America, it can be grown at an altitude of 1000-4500 meters. It is a kind of whole grain with high nutritional value, rich in 14%-22% protein, its content is twice that of rice; it contains high calcium, phosphorus, manganese, potassium, zinc, magnesium, iron and selenium, etc. A variety of mineral elements, its mineral element content is higher than that of ordinary grains, 2 times that of wheat, 5 times that of rice and corn; rich in 0.841-1.7 mg / 100 g of Ve, Vb, Vc and other vitamins and essential for human body 9 kinds of amino acids, especially containing about 4.6%-6.6% of lysine that is lacking in general grains; rich in unsaturat...

Problems solved by technology

Researchers have always focused on improving the quality and yield of flue-cured tobacco. In recent years, although they have realized that tobacco continuous cropping has caused soil nutrient imbalance in tobacco fields, accumulation of harmful substances, increased soil-borne diseases, and obvious decline in tobacco leaf yield and other problems, but The research on the continuous cropping obstacles of flue-cured tobacco is still not deep enough

Has not been able to find a good crop and good rotation with it, making its research progress slowly
