杂交油葵目前系国外引进。该作物生长期短,适应性广,抗逆性强,丰产性好,出油率及油品位高,栽培管理较易。但栽培管理是否得法,对产量和籽实含油率仍有较大影响。现将有关技术要点介绍如下: 一、选择适宜播期 杂交油葵全生育期90天左右,从4月上旬至7月下旬均可播种,一年可种植两季。从实践看,一般在高温期间开花灌浆的产量相对偏低, Hybrid sunflower is currently imported from abroad. The crop growth period is short, wide adaptability, strong resistance, high yield, oil yield and high oil level, cultivation and management easier. However, the cultivation and management of the law, the yield and oil content of seeds still have a greater impact. The relevant technical points are as follows: First, select the appropriate sowing hybrid sunflower full growth period of about 90 days, from early April to late July can be sown, planting two seasons a year. From a practical point of view, the yield of flowering grout is generally relatively low during high temperature,
