一从几个典型例子说起1.湖南道县朱鸿修稀播重肥,培育壮秧,早熟抗倒伏,增加产量:道县以一季中稻为主,是湖南秧田播种量最稀的一个地区;一般每亩播60—70斤,每亩本田用种约4斤。朱鸿修则播的更稀,合本田每亩用种量只1斤4两。朱鸿修育秧技术的主要特点是:(1)精选种,留好秧。每年进行田间穗选,再经室内选择稻穗上部三分之二的饱满谷粒做种;扯秧时更剔除生长不良的秧苗,达到
A typical example from a few 1. Hunan Road, Zhu Hongxiu thin seeding heavy crops, nurturing strong seedlings, precocious lodging, increase production: Daoxian mainly in a quarter of rice, Hunan slender seeding a rare area; general Sowing 60-70 kg per mu, about 4 kg per acre Honda species. Zhu Hongxiu is broadcast more dilute, with the amount of Honda 1 acre per mu 4 two. Zhu Hongxiu seedling cultivation techniques are the main features: (1) selected species, leaving good seedlings. Each year field spike election, and then by indoor selection of two-thirds of the top panicles of rice to do species; pull when removing more malting seedlings, reaching
