Abstract
The invention relates to an oily sunflower planting method and application thereof in an early rice-oily sunflower-rape triple-cropping system. The oily sunflower planting method comprises the following steps: (1) selecting an improved variety, carrying out plowing, carrying out basal dressing, carrying out furrowing and compartment dividing, and carrying out pitting; (2) carrying out seed manure applying, carrying out sowing, and carrying out irrigation; and (3) carrying out field management and harvesting: carrying out resowing or replanting, and carrying out water drenching; carrying out final thinning, carrying out intertillage weeding, and covering compartment faces of oily sunflowers with rice straws; carrying out topdressing prior to budding of the oily sunflowers; carrying out moisture management after the budding of the oily sunflowers; carrying out disease and insect pest control; carrying out pollination or fertilization; and carrying out harvesting. The oily sunflower planting method disclosed by the invention can be applied to the early rice-oily sunflower-rape triple-cropping system. The oily sunflower planting method disclosed by the invention is high in oily sunflower yield, light in crop disease, insect and weed damage, low in chemical fertilizer consumption and low in cost, can be used for fertilizing soil fertility, improving soil and protecting cultivated land productivity, is water-saving and can be applied to early rice-oily sunflower-rape triple-cropping system planting. According to the application disclosed by the invention, through reasonably matching early rice-oily sunflower-rape varieties, the link-up of oily sunflower-rape crops for rotation is improved, and grain-oil double good harvest, i.e., 500kg of grains per mu and 200kg of oil per mu is achieved.
Description
technical field [0001] The invention relates to a planting method of oil sunflower and its application, in particular to a planting method of oil sunflower and its application in the triple cropping system of early rice-oil sunflower-rape. Background technique [0002] Oil sunflower is an important oil crop in my country, which has the characteristics of drought tolerance, poverty tolerance, strong adaptability, short growth period and high oil content. As a nutritional and health-care edible oil, sunflower oil contains high levels of oleic acid and linoleic acid, of which linoleic acid is an indispensable fatty acid for the human body. Oil sunflower has a short growth period and is widely planted in northern regions. In recent years, the middle and lower reaches of the Yangtze River have developed rapidly. The middle and lower reaches of the Yangtze River have a long frost-free period and sufficient heat. Oil sunflowers can be sown in spring or autumn. At present, oil sun...
