试验目的和经过为了探明杂交稻秧田分蘖移植本田成穗并长出第1次有效分蘖的规律,探明常规稻本田第1次各蘖位分蘖的出现率、成穗率和穗粒性状,分别于1982及1983年早季稻采用“汕优2号”,1981—1982年早、晚季稻采用“桂朝2号”,以不同秧苗类型、不同移植叶龄试验为主,并在1975、1976年早季稻“珍珠矮11号”、“广二矮5号”、“IR8号”等亩产800—1100斤高产田进行分蘖生长发育规律观察调查。试验地点在华南农学院农场跃进区。杂交
The purpose of the experiment and after in order to ascertain the law of tillering transplanted Honda into hybrid rice seedlings and grow the first effective tillering, to find out the first occurrence of tillering tillering tillering rate, spikelet and grain traits, Shanyou 2 was used for early season rice in 1982 and 1983 respectively. Early 1981-1982 and Guizhao No.2 were used for late season rice. The experiment was conducted on different seedling types and different ages of leaf transplant in 1975 , 1976 early rice “Pearl short 11”, “Guang Er short 5”, “IR8” and other 800-1100 kg per mu yield of tiller growth and development of the law to investigate the survey. Test site in South China Agricultural College farm Yuejin District. Hybridization
