再生稻是利用头季稻收割后的稻桩萌发再生苗而抽穗结实、一次插秧2次收获的栽培方式。它具有省工、省种、省肥、节水以及增产增收的优势。据报道,1995年福建省创造了杂交早稻加再生稻667平方米产稻谷1047.2公斤(其中杂交早稻630.5公斤,再生稻416.7公斤)的高产纪录。1995年,湖南杂交水稻研究中心在汉寿县护城村也创造了杂交中稻加再生稻667平方米产稻谷1007.8公斤的纪录。这种栽培方式在我省有着广阔的发展前景。 一、再生稻的生长特点 1.再生稻的生育期 一般为60天左右,如威优77早季4月2日左右播种,7月30日左右成熟收割;
Regeneration is the use of rice after harvest the first season rice paddy seedling germination and seedling heading and fruiting, a transplanting 2 harvest cultivation methods. It has the provincial labor, provincial species, provincial fertilizer, water and the advantages of increasing production and income. It was reported that in 1995 Fujian Province created a record high yield of 1047.2 kg (including 630.5 kg of early hybrid rice and 416.7 kg of regenerated rice) of 667 square meters of early rice plus ratoon rice. In 1995, Hunan Hybrid Rice Research Center also created a record of 1007.8 kilograms of hybrid rice with 667 square meters of paddy rice in Huocheng Village, Hanshou County. This cultivation method in our province has a broad development prospects. First, the growth characteristics of ratooning rice 1 ratooning rice growth period is generally about 60 days, such as Weiyou 77 early April about sowing, mature harvest around July 30;
