早稻部分: 我省双季早稻面积现有二千六百万亩,平均亩产仅五百斤左右,如何提高双季早稻的产量,是一个极其重要的问题。1978年我们选用良种广陆矮4号和科矮早两品种,栽培面积一亩。另有四分田用条摆法和插秧法进行比较试验。1979年仍选用常规品种广陆矮4号,栽培面积二亩,另用广陆矮4号和杂交水稻汕优7427—1进行肥料比较试验,面积6分。从播种后秧田育秧阶段,至插秧后的本田生育阶段,着重研究其生理特性、生长发育规律及与高产有
The part of early rice: The area of double-season early rice in our province now covers 26 million mu and the average yield per mu is only about 500 jin. How to increase the yield of double-season early rice is an extremely important issue. In 1978, we selected the best varieties of Guanglu Dwarf No. 4 and Branch Azawa two varieties of cultivated area of an acre. Another four-year field with pendulum method and transplanting method to compare the test. 1979 is still the choice of conventional varieties Guanglu dwarf 4, the cultivation area of 2 acres, the other with Guangluai 4 and hybrid rice Shanyou 7427-1 for fertilizer comparison test, an area of 6 points. From sowing seedling seedling stage, to transplanting Honda growth stage, focusing on its physiological characteristics, growth and development and with high yield
