在早稻栽培上如何力争较多的分蘖成穗,并在充分利用分蘖穗的同时,如何确保穗部性状,已成为高产栽培中一个不可忽视的问题。进一步了解常规稻的生物学特性,摸清分蘖消长及发育规律,为大面积高产栽培提供科学依据实属必要。为此,1982—1983年我们在澧县平原农技站对常规早稻分蘖特性进行了详细观察,同时对分蘖的利用进行了探讨。 一、材料与方法 供试品种广陆矮4号,每亩播种量设15、30、45、60、75、90公斤共六个处理,
In the early rice cultivation how to strive for more tillers into spikes, and make full use of tillering spike at the same time, how to ensure the ear traits, has become a high yielding cultivation can not be ignored problem. Further understanding of the biological characteristics of conventional rice, find out the growth and development of tillers and find out the scientific basis for large-area and high-yield cultivation is necessary. For this reason, we conducted a detailed observation on the tillering characteristics of conventional early rice in Yixian Plain Agricultural Technology Station from 1982 to 1983, and discussed the utilization of tillers. I. Materials and Methods The cultivars Guangluan 4 was planted with 15, 30, 45, 60, 75 and 90 kg of seeding per acre for a total of six treatments,
