不同栽培密度对甬优7872产量及品质等农艺性状的影响

为探讨栽培密度对水稻产量及品质影响,提升优质稻米品质。以甬优7872为试验材料,设置5个栽插密度(30 cm×24 cm,30 cm×21cm,30cm×18cm,30cm×16cm,30 cm×14 cm),测定甬优7872的 产量及品质。试验结果显示栽培密度的增加,生育期缩短,分蘖力随栽培密度的增大而减弱,产量对着密度的增加,呈先增加后减少趋势。栽插密度为30 cm×24cm时,甬优7872稻米综合品质最好。栽插密度30 cm×16cm时,甬优7872平均亩产最高。甬优7872的优质高产稳产,栽插密度30 cm×18cm更加适宜。

Effects of Different Planting Densities on Yield and Quality of Yongyou 7872

In order to explore the effect of planting density on Rice Yield and quality, the indica japonica hybrid rice Yongyou 7872 was used as experimental material. Set 5 planting densities (30cm×24 cm,30cm×21cm,30cm×18cm,30cm×16cm,30cm×14cm).The results showed that with the increase of planting density, the growth period was shortened, the tillering ability decreased with the increase of planting density, and the yield increased first and then decreased with the increase of planting density. The planting density is 30cm×24cm, the comprehensive quality of Yongyou 7872 rice was the best. Planting density 30cm×16cm, the average yield per mu of Yongyou 7872 was the highest. Comprehensively considered. In order to achieve high quality, high yield and stable yield of Yongyou 7872, the planting density is 30 cm ×18cm is more suitable.
