1978～1979年,我站做了秧苗素质与产量关系试验。结果证明,稀播秧苗素质好,大田产量高。 (一)不同播种量与秧苗素质的关系在上述期间,我们用加农485品种做了80～200斤/亩播种量与秧苗素质关系试验,移栽时考察秧苗素质,结果见表1。从表1可以看出,同样品种相同秧令、不同播种量,秧苗素质差异很大。在以上范围内,秧苗素质随着播种量的减少而提高。 (二)不同秧苗素质与大田早发的关系试验证明,以7种不同素质秧苗同期移栽大田,密度同为3.2万/亩,考查的项目及结果见表2。
From 1978 to 1979, I made a test of the relationship between seedling quality and yield. The results show that seedlings planted seedlings good quality, high yield field. (A) the relationship between different sowing and seedling quality In the above period, we use the Gannon 485 varieties made 80 ~ 200 kg / acre seeding rate and the relationship between the quality of seedlings, seedlings transplanted quality, the results in Table 1. As can be seen from Table 1, the same varieties of the same seedlings, sowing different, very different quality of seedlings. Within the above range, the quality of seedlings increased with the reduction of seeding rate. (B) the relationship between quality of different seedlings and early field trials showed that 7 different quality seedlings transplanted in the same field, with the same density of 32,000 / mu, test items and results in Table 2.
