连续两年在川南盆地灰棕紫泥水稻土上进行田间试验.结果表明,再生稻吸收养分起初有一短暂的停滞期,而后则急剧上升.20天可吸收总需要量的90%以上,抽穗后的30—35天,养分吸收量不到总需要量的10%.稻茬中的养分含量可显著提高潜伏芽的萌发率.在中稻收割之后,它们随即向下部潜伏芽萌发的部位运转.在一定的施肥条件下,气候是再生稻的限制因子,故再生稻施肥不宜过多.
Field experiments were conducted on gray-brown purple clay soil in the south of Sichuan Basin for two consecutive years.The results showed that the nutrient absorption of ratooning rice began to have a short period of stagnation at first, and then rose sharply.After 90 days, Of the 30-35 days, nutrient uptake less than 10% of the total demand of the nutrient content of rice stubble can significantly increase the germination rate of latent buds in the middle rice after harvest, they immediately germinated buds to the lower part of the site operation in Under certain fertilization conditions, the climate is a limiting factor for ratooning rice, so fertilization of ratoon rice should not be too much.
