A cultivation technique for hybrid oilseed sunflowers, which relates to a crop cultivation technique, is characterized in that the cultivation technique for the hybrid oilseed sunflowers includes the following method and steps: variety selecting: a short-straw, high-yield and stable-yield variety with good earliness needs to be chosen for spring sowing; soil preparation and fertilization: 5000 kilograms of well-rotted farmyard manure and 30 kilograms of nitrogen-phosphorus-kalium compound fertilizer are applied per mu, and after uniform application, the land is deeply tilled; sowing time: sowing is normally carried out within fifteen days after the mid of March, the hole sowing method is mostly adopted, and the density per mu is about 3800 plants; field management: after oilseed sunflower seedlings emerge, the seedlings are checked in time, the seedlings are supplemented in time, and when two to three pairs of true leaves appear, weeding, thinning and final singling are carried out by being in combination with intertillage; pest control: 50 percent of phoxim or solution 1000 times as much as chlorpyrifos can be chosen to be sprayed on the land surface at the seedling stage, the manual pest-catching method rather than pesticide can be adopted at the flowering stage, and highly effective cypermethrin pesticide can be chosen for pest control at the seed-setting stage; and timely harvesting: preferably, harvesting is normally carried out in late June to early July according to harvesting standards that: the backs of oilseed sunflower discs become yellow, bracts become brown, stems have yellow flowers, and seeds are hardened. The yield of the hybrid oilseed sunflowers cultivated by the cultivation technique is high, the oil yield rate is high, time and labor are saved, and the economic benefit is high.
