用３个不同熟期的优质籼稻银桂粘、金麻粘和金竹粘，以中早熟高产品种广二矮１０４为对照，在省内４个不同生态地区进行分期播种试验。结果表明，早熟品种银桂粘在海拔１１００ｍ以上温凉地区，中迟熟品种金麻粘和金竹粘在９００ｍ以下热量较好地区适期播种条件下，都能获得较高的产量。品种的精米率受试点和播种期的影响较小，整精米率、垩白粒率和直链淀粉含量受试点和播种期影响较大；不同的生态条件对不同品种影响不同；产量与稻米蛋白质含量成负相关。
Three high-yielding indica varieties of Yin Gui sticks, Jin Ma sticks and Jin Zhu sticks were used in this study. The high-yielding mid-early maturing varieties Guang Er short 104 were used as control, and the sowing experiments were carried out in four different ecotopes in the province. The results showed that the early-maturing variety Yin Gui sticky in the cool area above 1100m above sea level, the mid-late maturing varieties Jinma sticks and the golden bamboo sticks could get the higher yield under the suitable sowing conditions under the 900m heat. The rice yield of varieties was less affected by the experiment and the sowing date. The milled rice rate, chalky grain rate and amylose content were greatly affected by the experiment and sowing date; different ecological conditions had different effects on different varieties; the yield and rice protein The content is negatively correlated.
