我所在早稻高产栽培中,曾先后采用依靠主穗和分蘖穗这两条途径.前一条途径是历史上沿用的,采用多年,亩产量可以达到1,100斤左右的水平.但产量要再上去,困难较多,诸如通风透光条件差,病虫害多,易倒伏,穗形小等常成为产量进一步上升的障碍.后一条途径经过最近两年的小区试验和大田示范试验,显示出较多的优越性,亩产量可以达到1,200斤以上.其中1979年的大田高产示范试验,面积为2.3亩,平均亩产达1,214斤,为我所历史上早稻单产最高纪录.现将我们几年来的试验结果及依靠分蘖穗为主夺取高产的几个问题作如下小结.
In our high-yielding early-rice cultivation, we have adopted two methods: relying on the main spike and tillering spike. The former approach is historically used and has been in use for many years with a yield of about 1,100 kg per mu. More, such as poor ventilation and light conditions, pests and diseases, easy to lodging, spikelets and other often become obstacles to further increase in output.After the last two years of cell test and field demonstration test, showed more advantages , Mu yield can reach 1,200 pounds or more.Among them in 1979 field demonstration project of high yield field, an area of 2.3 acres, an average of 1,214 pounds per mu, for my record high yield of early rice in history. Now we years of test results and rely on Tilting spike to seize the high yield of several issues as summarized below.
