杂交水稻育秧技术要求与常规品种不同,这主要由于杂交水稻的特性与常规种不同。如杂交水稻第一代种子是一种杂合体,有它特有的杂种优势。这种优势表现于根系发达,对水肥吸收力强,因而地上部份生势旺盛,分蘖力强,穗大、粒多。所以在栽培杂交水稻时,应充分利用它的优势潜力。其欣是杂交水稻的种子,是经过不育系与恢复 The technical requirements of hybrid rice seedlings are different from the conventional varieties, which is mainly due to the different characteristics of hybrid rice and the conventional ones. Such as hybrid rice first-generation seeds is a hybrid, with its unique heterosis. This advantage is manifested in the developed root system, strong absorption of water and fertilizer, so vigorous growth of the upper part of the strong tillering, spike, grain and more. Therefore, when cultivating hybrid rice, it should make full use of its potential advantages. Its Xin is the seed of hybrid rice is through sterile lines and recovery
