1976年,我地区长期低温寡照,水稻生育期推迟,为探索促进水稻生长、早熟,免遭霜冻灾害的途径,我们分不同时期、不同长势和不同剂量三种情况喷洒“721”石油助长剂进行试验。试验看出,喷洒“721”能促进早熟,提高产量,尤其对三类苗和贪青晚熟的水稻,作用更为明显。现将试验情况、调查结果整理如下。一、试验内容及方法喷洒“721”共分三个处理:1、不同时期喷洒试验:分别在水稻
In 1976, the long-term low-temperature region in our region was delayed and the growth period of rice was postponed. In order to explore ways to promote rice growth, precocious puberty and frost disaster, we sprayed “721 ” oil at different times, different growth conditions and different doses Agent test. Test shows that spray “721 ” can promote early maturity and increase yield, especially for three types of seedlings and late greyish rice, the role is more obvious. The test situation, the survey results are summarized below. First, the test content and methods Spray “721 ” is divided into three treatment: 1, spraying test in different periods: respectively in rice
