79年我室以“化杀”组合赣化2号为材料,对蘖节栽培的水稻生育特性进行了观察研究,证明蘖节栽培比种子栽培更能显示出杂交优势,因此,它在生产上有一定的利用价值。材料和方法试验于我院试验场进行,供试组合赣化二号,种子由我所水稻室杂优组提供,试验田面积2.7亩,辅助试验每小区0.1亩,不重复。秧田每亩落谷30斤,4月25日落谷,按常规方法培育带蘖壮秧,5月25日移植至繁殖田,6月23日将秧苗剪叶、剪根、剥蘖,制成10厘米长的蘖节扦插,生育期间取样考查株高、干重、叶面积、绿叶数、分蘖数、
In 79 years, we used the “Kill and kill” combination Ganhua No.2 as the material to observe the growth characteristics of rice in tillering stage and proved that the growth of tillering section can show the advantage of hybridization more than the seed cultivation. Therefore, Have some use value. Materials and methods The experiment was carried out in the experimental field in our hospital for the combination of Ganjiang II. The seeds were provided by the rice hybrid lab in our lab. The experimental plot area was 2.7 mu and the auxiliary experiment was 0.1 mu per plot, which was not repeated. Seedling fall valley 30 acres per acre, April 25 Valley of the Fall, according to the conventional method of cultivating strong sprout with tiller, May 25 transplanted to the breeding field, June 23 will cut the leaves of seedlings, cut the roots, peeling tillers, made of 10 Centimeter long tillering cuttings, sampling during growth to check plant height, dry weight, leaf area, number of green leaves, tillering number,
