湖南稻田种植制度,主要是绿肥-双季稻。水稻生产中存在的问题,主要是:土壤耕作一般田早稻采取二犁三耙,晚稻田采取一犁二耙,泥土整得成浆,以致土壤结构被破坏,泥沙分家,浮泥封面,通透性变差,不利水稻生长。双季稻面积大,传统的育秧移栽,收早稻插晚稻时,劳力十分紧张;早稻插秧后常遇到5月低温和晚稻插秧后,因7月下旬高温天气,禾苗生长发育慢,造成单位面积的苗数、穗数不高, Hunan rice cultivation system, mainly green manure - double cropping rice. The main problems in rice production are as follows: soil tillage Generally, the early rice in the field adopts the second harrow and the second harrow in the early rice paddy, and the second harrow in the late rice paddy produces the whole soil, resulting in the destruction of the soil structure, sediment separation, Permeability worsened, unfavorable to rice growth. Double paddy rice area, the traditional seedling transplanting, early rice plugging late rice, labor is very tight; early rice transplanting often encountered in May after low temperature and late rice transplanting, due to high temperature in late July, the growth and development of slow seedlings, resulting in units The area of ​​seedlings, the number of spikes is not high,
