再生稻一次种,两次收,省种、省工、省时间。种得好再生稻亩产可达300～400公斤,头季加再生稻亩产可达800～900公斤。在无霜期短,不宜种两季的高寒山区,发展杂优再生稻,是增加粮食产量的有效途径。从近几年的实践来看,栽培再生稻要抓好以下几项技术措施。一、选择适宜再生稻生长的土壤。以选择沙质壤土为好。因沙质壤土通透性好,稻根活力强,寿命长,增强再生能力。
Ratooning once species, twice received, provincial species, provincial workers, save time. Kinds of reborn rice well up to 300 ~ 400 kg per mu, up to 800 ~ 900 kg per mu in the first season plus renewable rice. In the frost-free period is short, not suitable for two seasons alpine mountains, the development of hybrid rice, is an effective way to increase food production. In recent years of practice, cultivation of ratooning rice should do a good job in the following technical measures. First, choose suitable ratoon soil growth. To choose sandy loam as well. Because of sandy loam permeability, rice root vigor, long life, enhance regeneration.
