目前我县早造种植的水稻优质品种“玻惠占”、“新早占”、“新惠占”等,与三号粮比较起来,有一个共同的弱点就是穗小、粒少、粒细,因此,优质品种的产量普遍比三号粮低。要从根本上提高水稻优质品种的产量,一方面有待品种的改良,把小穗细粒的优质品种,逐步改为中穗中粒的优质品种。在这个基础上提高栽培技术。为了提高现有水稻优贡品种的产量,1985年早造我们对水稻优质品种的秧苗素质、插植苗数、施肥方法、病虫防治等进行一些试验,根据初步试验结果,要夺取早造水稻优质品种的高产,则要抓好如下措施。
At present, the fine varieties of rice that were planted and grown early in our county, such as “Bohui Zhanzhan”, “Zaozhanzhan” and “Xinhuizhan”, have a common weakness compared with No.3 grain, which is spike, small grain, fine grain Therefore, the yield of high-quality varieties is generally lower than that of No.3 food. To fundamentally improve the yield of high-quality rice varieties, on the one hand, the varieties to be improved, the fine varieties of fine spikelets, gradually replaced by medium-sized grains in the high-quality varieties. On this basis to improve the cultivation techniques. In order to improve the yield of the existing Yugong rice varieties, some experiments were carried out in early 1985 on the qualities of seedlings, the number of planting seedlings, the method of fertilization, the prevention and control of pests and diseases of the high quality rice varieties. According to the preliminary test results, Variety of high yield, we must grasp the following measures.
