不同播种期和插秧苗数对‘特优107’产量的影响
|
摘要
为了进一步研究杂交水稻新品种‘特优107’获得较高产量的理论依据,通过采用二因子随机区组设计,在早、晚两季探讨不同播期与苗数对产量构成因素的影响。结果表明:早播种生育期拉长,特别是早季更加明显;增加基本苗数,可以缩短生育期;播种期与苗数的变化主要引起穗粒数和穗数的变化,对产量的影响均达极显著水平;晚季播种期与基本苗两者的互作对产量的影响达极显著水平,而早季未达显著水平。通过适宜的播期和一定的苗数,在主攻穗数的前提下,增加穗粒数,可以提高生产潜力。‘特优107’在闽南做早、晚季栽培,在中肥水平条件下,早季2月中旬末,晚季7月中旬初播种,每公顷基本苗插56.7万苗左右,可以获得较高的产量。
This article is mainly about influences of different sowing time and basic seedlings to yield component of ‘ Teyou107 ’ in early and late seasons. The results showed that, sowed earlier would prolong the growth period, especially in early season. The increase of the basic seedlings in quantity would shorten the growth period. Different sowing time and basic seedlings could cause to change the spike number and grain number per spike, the influence to the yield was significant. The influences to the yield of late season interacted with basic seedlings was significant, but in early seasons it did not reach the significant level. On the premise of proper sowing time, basic seedlings and enough spikes would bring its superiority of big spike, could enhance the potential of increasing production. ‘ Teyou107 ’ was cultivated in early and late seasons in southern Fujian. Under an average soil condition, ‘ Teyou107 ’ should sow in late midmonth of February and midmonth of July with 567000 seedlings/hm 2 to get higher yield.
