1.离蘗分栽。播种吋单粒点播,粒距4～5厘米,增施氮肥加强管理,争取多分蘗。移栽时把具有独立根系的分蘗剥离分栽,采取稀植线插,高肥培育,浅水灌溉,适时露田。不育系可剥1～2次,保持系可剥3次,扩大繁殖系数。不育系在离蘗分栽时,注意主茎与各次分蘖要分片种植以免抽重抽穗不整齐。一般采用移父繁殖法,即每插4～5行母本留60厘米的父本行。保持系由于种子较多应该分期播
Divided from the tiller planted. Sowing inch single-point on-demand, grain spacing 4 ~ 5 cm, nitrogen fertilizer to strengthen management, strive for more tillers. When transplanting, the tillers with independent root system should be separated and planted, and the plants should be planted with thinning lines, high fertility, shallow irrigation and timely dew field. Sterile lines can be stripped 1 or 2 times, to maintain the peel 3 times, to expand the breeding coefficient. Male sterile lines in tillering sub-plantation, pay attention to the main stem and each tiller to be planted in pieces so as to avoid heading irregularly. The general use of parenting propagation method, that is, each insert 4 to 5 female parents stay 60 cm father line. Maintained by the seed should be more broadcast
