随着我省三熟制面积不断扩大,早稻在5月中旬至5月底栽插的面积逐步增加,为了提高中迟熟茬口早稻的产量,我们进行了不同播种期的试验,摸索中茬口早稻应用趸秧的适宜播种期,为提高中茬口早稻的产量提供理论依据。供试品种华矮32号,播种期共分两批,即三月二十六日四月十二日,移栽期都是五月七日。小区面积为0.02亩,三月二十六日播的未设重复,四月十二播的设了三次重复,管理一般。现将试验结果小结如下:
With the continuous expansion of the three-cropping system in our province, the planting area of early rice increased gradually from mid-May to the end of May. In order to increase the yield of early-late mature rice, we conducted the experiment of different sowing dates and explored the application of middle-crop early rice Suitable for sowing seedling sowing period, in order to improve crop stubble yield of early rice provide a theoretical basis. The test varieties Hua-dwarf 32, sowing period is divided into two batches, that is, March 26, April 12, transplanting period is May 7. The plot area is 0.02 mu. There was no repeat on sowing on March 26 and three repetitions on April 12 for general management. The test results are summarized as follows:
