1 主要栽培技术要发挥培杂双七优质高产特性,就必须针对培杂双七的特点,实施科学的栽培技术做到良种良法配套。一是针对培杂双七主要靠分蘖成穗为主(占总穗数80%)的特点,在栽培上要注意培育适龄壮秧,抛(播)足基本穴数(一般为1.6万穴/667m~2左右),采取抛秧或浅插,以增加低位分蘗。同时,由于培杂双七的千粒重较轻,属穗数型组合,应适当增加用种量(用种量一般为1.25kg/667m~2),以增加基本苗,从而提高有效穗数。二是针
1 main cultivation techniques To play Peiqi high quality and high yield characteristics, it must be Pei Shuangqi characteristics, the implementation of scientific cultivation techniques to achieve good varieties of good law. First, Pear is mainly due to the characteristics of Pear Paniculata mainly tillering panicles (accounting for 80% of the total number of spikes), in cultivation should pay attention to cultivating age seedlings, cast (broadcast) foot basic points (usually 16,000 points / 667m ~ 2 or so), to throw throwing or shallow inserted to increase the low tiller. In the meantime, due to the light weight of 1000 seeds per spike of Panax notoginseng and the combination of spike number, the seedling should be increased appropriately with the dosage of 1.25kg / 667m ~ 2, so as to increase the effective spike number. The second is the needle
