参加全国第三届水稻高产理论与实践研讨会的代表指出,高产地区水稻持续增产,必须采取综合措施,除选用良种、改土和治水等措施外,在技术路线上须明确以下几条原则: (1)不能走亩增穗数的途径,必须走稳定适宜穗数,稳攻大穗的“小群体、壮个体、高积累”的栽培途径。(2)根据品种、前茬、秧龄特点,培育叶蘗同伸壮秧。(3)按照有效分蘗叶龄期够苗的严格要求,按移栽秧苗的特点,通过计算,确
Representatives participating in the Third Seminar on Theory and Practice of High Yield Rice in the People’s Republic of China pointed out that the paddy in high-yielding areas should continue to increase production. Comprehensive measures must be taken. In addition to such measures as selection of improved seeds, improvement of soil and water control, the following principles must be clarified on the technical route: (1) If we can not take the path of increasing the number of spikes per acre, we must adopt the cultivation method of “small groups, strong individuals and high accumulations” to stabilize the number of spikes and stabilize the large spikes. (2) According to the variety, stubble, seedling age characteristics, cultivate leaf tiller with stretch strong seedling. (3) In accordance with the strict requirements of effective tillering leaf age enough seedlings, according to the characteristics of transplanted seedlings, by calculation, indeed
