我队每年宿根蔗占总植蔗面积60%左右,其中有8年的,有5～6年较大面积平均亩产5吨多的宿根蔗。第1～3年的宿根蔗产量一般高于新植蔗,因栽培宿根蔗面积多,对节省劳动力、种子、肥料和错开农时、达到粮蔗双丰收有极大的好处。但宿根蔗往往发芽不稳定,难能保证稳产高产。为了确保宿根蔗高产,就得促进蔗芽早出苗、壮苗和分布均匀。要达此目的,就得根据不同的气候条件特点,掌握它的规律,采取相适应的措施。我们的体会是:
Each year, our team occupy 60% of the total planting area of sugarcane, of which there are 8 years, there are 5 to 6 years larger area average yield of more than 5 tons of perennial sugarcane. In the first to third years, the yield of ratoon cane was generally higher than that of new cane. Because of the large area of cultivated ratoon cane, it is of great benefit to save labor, seeds, fertilizers and stagger agriculture when it achieves double harvest of grain cane. However, stubble sugarcane often unstable, it is difficult to ensure stable and high yield. In order to ensure the high yield of ratoon cane, we must promote early emergence of cane shoots, strong seedlings and distribution. To achieve this goal, we must grasp its laws and take appropriate measures according to different climatic conditions and characteristics. Our experience is:
