以实践认识为基础,结合已有的高产栽培理论与技术,提出浙江超级稻一季15 t·hm-2栽培的基本技术原则。即选用籼粳交偏粳型、大穗特大穗、强抗倒的超级晚稻品种;培育超高产农田,使土壤基础肥力产量稳定达到9 t·hm-2以上;以日平均温度26~27℃常年出现日期作为抽穗期安排播种期;以多穗为目标,确定移栽的基本苗数;培育叶蘖同伸适龄壮秧并择日移栽,促早发够苗;实行超宽行距,使群体封行期推迟到抽齐穗期;按测土配方施肥原理框定肥料总量;以叶色前见无效分蘖期“黄”、后见稻穗“破口黄”为原则,稳前、攻中、控后施肥,“浅—深或和搁—湿”为序水分管理;根据高肥量大群体特点加强病虫防治。
Based on practical knowledge and combined with the existing high-yielding cultivation theories and techniques, the basic technical principles of Zhejiang super-rice cultivation of 15 t · hm-2 in the first season were put forward. That is, selecting the super late rice varieties with japonica-japonica cross japonica type, big panicles with big ears and strong anti-fall; cultivating super-high-yielding farmland so that the soil fertility yield could reach more than 9 t · hm-2. The daily average temperature ranged from 26 ℃ to 27 ℃ The perennial emergence of the date as a heading date for sowing; with more spike as the goal, to determine the basic number of transplanted seedlings; cultivate leaf tiller with the age of suitable age seedlings and choose day transplanting, early hair seedlings; The group seal postponed to the pumping full heading; according to the principle of soil testing and fertilizer formula frame the total amount of fertilizer; leaf color see the invalid tillering period “Yellow ”, see the rice “broken mouth yellow ” principle, Steady before the attack, the post-control fertilization, “shallow - deep or and put - wet ” in order of water management; pest control according to the characteristics of a large number of high-fat mass pest control.
