我区一九七二年双季早稻的插秧季节,普遍比往年提早一周至半个月。大部分地区在三月上旬试插,三月中旬大插,四月下旬基本插完。大多数地区由于适时提早插秧,提早了成熟,增加了产量,对全区夏粮增产六千多万斤有重要作用。但是,也有一些地区盲目追求早插,引起寒害死苗,影响了产量。为了防止一种倾向掩盖另一种倾向,掌握好早稻的插秧时间,夺取早稻高产,我们对如何适时提早双季早稻的插秧问题作了一些调查,现综述如下。
The planting season of double-season early rice in 1972 in our district is generally one week to half a month earlier than previous years. In most parts of the trial in early March, plug in mid-March, basically finished in late April. In most areas, because of timely early planting, early maturity and increased output have played an important role in increasing more than 60 million kilograms of summer grain in the region. However, there are also areas that blindly pursue early planting, causing cold damage and death and affecting output. In order to prevent one kind of tendencies to cover up another tendencies, grasp the planting time of early rice and seize the high yield of early rice, we made some investigations on how to timely early planted the rice seedlings of double-season early rice and are summarized as follows.
